Illustrative activity — the kind of moments the app surfaces.

The loop

Three ways in. One balance.

Everything you do lands in the same pile of TVX. TVX raises your Level; Level unlocks bigger rewards. No wallet, no gas, no waiting.

Mine

One tap starts a session that keeps earning even when the app is fully closed. A notification tells you when it's ready to claim.

Watch

Rewarded video pays TVX on top, verified before it lands. Every fourth ad lights a boost window; a lucky roll can multiply the payout.

Check in

A flat daily reward that builds a streak. The streak adds a permanent bump to your mining rate — and breaking it hurts.

A small RPG bolted onto the loop.

TVX has somewhere to go. Buy a pickaxe, upgrade it through levels, and fold its bonus into your mining rate — or spend on timed boosts, unlocks and cosmetics that never touch the earn rate.

Global top 100 — and your own league.

The weekly board resets every ISO week and shows the top 100. Everyone also races a smaller league — eight tiers, Bronze to Legend, up to 30 players a group. Finish in the top fifth and you're promoted Monday; mine nothing and you drop. Your own row tells you the gap to the spot above in real TVX — and there’s a global chat room for talking shop while your rig mines.

Badges to earn

No small print

An economy you can audit.

Rewards apps are usually vague about the maths. Not this one. Every bonus is added, never compounded, so the maximum earn rate is finite and knowable no matter how many systems you stack.

The whole parameter set — rates, caps, costs, windows — is published in the whitepaper, and it's the same config the client and server both read.

Illustrative stack for an early player. Each segment is a capped source; the rate is their sum, applied once.

TVX is the in-app unit you mine, not currency. Today it has no cash value, can’t be bought and can’t be cashed out — you spend it in the Marketplace on pickaxes, boosts and cosmetics. Ads are standard rewarded video — watching is always your choice.

Roadmap

Version 1.0.3: crews, eras and 105 badges.

TAVEXA MINI is live on Google Play, and Phase 3 — growth — is well under way: crews, Eras and the Vanguard, 105 badges that pay TVX, public profiles, promo codes and an ambassador program with real perks.

Phase 0 — Foundation Phase 1 — Engagement Phase 2 — Launch Phase 3 — Growth Phase 4 — Depth

Questions

The short answers.

Is it free? What does it cost?

It’s free to install and play. There’s nothing to buy to earn TVX; ads are optional and pay extra, they’re not the price of entry.

Is this crypto? Can I cash out?

Not today. There’s no tradable token and no blockchain, and TVX can’t be cashed out — it’s the in-app unit you mine, with no monetary value. You spend it in the Marketplace on pickaxes, boosts and cosmetics.

What are Crews?

A group of up to five players. On any day three or more of you claim a mining session, everyone who mined gets a bonus: +30 each at three, +40 at four, +100 when all five mine. Crew members need Level 3 to count.

What are Eras and the Vanguard?

Eras are a mining bonus for the whole community that steps down as it grows: +100% in the Genesis Era (the first 2,500 miners), then +75%, +50%, +30%, +15%. The first 250 miners to reach Level 5 are the Vanguard and keep +5% mining for good.

Will it drain my battery or data?

No. Mining is computed on the server from elapsed time when you claim — nothing runs on your phone while the app is closed. You only get a notification when a session is ready.

Which phones does it run on?

Android first — available now on Google Play. There’s no iOS release announced yet.

How old do I have to be?

16 or older. The ambassador and partnership programs are 18+.

Can I delete my account and data?

Yes, any time — in the app under Settings → Account, or by email. Here’s how.

Whitepaper

The TAVEXA MINI economy

A rewards app lives or dies on trust. Most are opaque about how earning works; this document is the opposite. It states every source of TVX, every bonus, every cap, and the mechanisms that keep the system fair.

Update, 2 November 2026: TVX is the in-app unit you mine. Today it has no cash value, there is no cash-out and no tradable token. The cash-out and token plans described on this page are on hold — they are kept as a record of earlier thinking and are not a commitment or a promise of value.

§1Abstract

TAVEXA MINI rewards attention and consistency with TVX — a virtual, in-app balance with no monetary value and no relationship to any cryptocurrency or security. TVX is earned three ways: a passive mining session that accrues while the app is closed, optional rewarded video ads, and a daily check-in. Layered on top are streaks, a weekly pass, weekly missions, timed events, level milestones and a referral team, each of which modifies the earn rate or pays a bounded bonus.

Today, TVX is not a token and carries no promise of value. A gift-card redemption feature is engineered, and it stays switched off until the conditions in §9 are met. This is a deliberate sequencing, not an accident: the product is a rewards app first, proven at real scale, before any cash value enters the picture — never the other way around. §9 sets out exactly when redemption turns on; §10 sets out, with the same discipline, the only conditions under which a broader liquidity mechanism would ever be considered. Neither section promises a date or a price. Both exist so that if either ever happens, it happens because the numbers earned it, not because a roadmap said so.

What remains is a game about a machine that earns for you. The rest of this paper describes how that machine is balanced and defended.

§2Design goals

Retention through honest urgency, not dark patterns

Engagement mechanics are timed windows the player can see and reason about — a three-hour boost after completing the daily goal, a repair window after a broken streak, a countdown on a live event. There are no hidden timers, no pay-to-skip walls, no loot boxes bought with real money. The pull to return is "your boost is live for two more hours", stated plainly.

Bounded rewards

Every bonus source has a hard cap, and bonuses are summed rather than multiplied (§4). The maximum possible earn rate is knowable and finite regardless of how many systems a player stacks, so the economy cannot be inflated into meaninglessness by a small number of maximised accounts.

Server authority

The client never decides what a reward is worth. A mining claim's payout is computed by the server from the session's recorded start time and a rate locked in at start; an ad reward is credited only after the ad network's server-to-server verification confirms the view. The client runs a copy of the same rules only for an optimistic preview, which the server reconciles.

Fraud resistance as a first-class feature

A reputation score, deterministic idempotency on every mutation, a replay guard on the ledger, and a level-and-activity gate on referral rewards are built into the core loop, not bolted on. See §7.

§3The TVX economy

All earning credits a single append-only ledger; the running balance is the sum of its entries. TVX raises the account Level from cumulative lifetime earnings across a 50-step curve, and Level unlocks higher ad caps, higher earn multipliers and milestone rewards.

Sources and sinks
Flow	Mechanic
Source	Idle mining — 15 TVX/hr base, 4–8 h sessions, rate modified by every bonus in §4
Source	Rewarded ads — 9 TVX base × earn multiplier × boost × ad-streak × event × luck
Source	Daily check-in — 11 TVX + 2 per level (13 at Level 1, 111 at Level 50), up to four times a day, streak advances once
Source	Reward tasks & weekly missions — small credits for in-app actions; weekly missions grow +20% per 10 levels
Source	Weekly Pass — 7 tiers, 15→225 TVX, one per check-in day that week
Source	Mystery Box — a bounded random amount, once daily from Level 3
Source	Level milestones — 375→37,500 TVX at Levels 10/20/30/40/50, once each
Source	Referral activation — +150 once a referred friend reaches Level 3
Source	Badges — 50 / 150 / 500 / 1,500 / 5,000 TVX the first time each family reaches tier I–V
Source	Crew bonus — 30 / 40 / 100 TVX each on a day 3 / 4 / 5 Level-3+ crew members claim a session
Source	Promo codes & program rewards — added to the balance only: they don’t raise Level and don’t count on the weekly leaderboard
Sink	Marketplace pickaxes — one-time purchase then upgrades; the only rate item bought with TVX
Sink	Store — consumables, timed boosts, permanent unlocks, cosmetics, a −25% daily deal

Cosmetic sinks (frames, pickaxe skins, chat colours) give TVX somewhere to go without touching the earn rate, so a player can spend without weakening their own progression.

§4The additive rate model

The mining rate is the most important number in the economy, and the way its bonuses combine is a deliberate choice. Every source contributes a bonus in basis points; those are summed, and the sum is applied once:

rate = 15/hr × (1 + Σ bonusBps / 10000)

Multiplicative stacking produces runaway numbers: five ×1.4 bonuses compound to roughly ×5.4, not ×3. Additive stacking keeps each source's marginal effect bounded and legible. A player with everything maxed knows exactly what their ceiling is.

Rate sources & caps
Source	Rate	Cap
Era (community size)	+100% → 0	locked at session start
Vanguard (first 250 to reach Level 5)	+5%	permanent
Active ambassador / partner	+5%	while the role is active
Check-in streak	+2% / day	+50% (25 d)
Active referrals	+2% / friend	+20% base, grows w/ level & unlock
Level milestones	+5% each	+25% (all 5)
Equipped pickaxe	rarity + level	bounded by catalog
Timed boost (Rush Hour / Overclock)	+50% / +25%	while active
Daily-goal boost	+10%	3 h window (5 h w/ Go-Getter)
Limited-time event	admin-set	event window

§5Rewarded ads

Ads are the revenue engine and are always optional. The player can run the entire loop — mining, check-ins, streaks, missions, the pass — without watching one; ads simply pay TVX on top.

Verification

A rewarded video is served by Google AdMob. The reward is credited only after AdMob's server-side verification callback confirms the impression to our backend. A request whose token belongs to another account, or which arrives before verification, is rejected; a verified token that is replayed is caught by the ledger guard (§7) and dings reputation.

Caps and gates

Daily cap by level: 15 ads at Level 1, rising to 50 at Level 50.
Minimum gap of 25 seconds between ads.
Reputation gate: below a score of 20, ad earning is blocked entirely.

Boost, luck, streak, double

Boost window — every fourth ad lights a 15-minute window in which ad rewards are +50%.
Lucky Ad — a per-ad roll: ~8% pay double, ~2% pay triple. The triple is surfaced as a celebration.
Ad Streak — consecutive days with at least one ad watched add +2% to ad rewards, capped at +20% over ten days. Independent of the check-in streak, with no freeze.
Ad Boost — for 180 seconds after a credit, watching one more ad adds 60% to that reward. One boost per ad; the offer expires with the timer.

§6Streaks & loss aversion

The check-in streak is the retention core. It advances once per calendar day (UTC) on the first check-in, and it does three things: pays milestone bonuses at 3, 7, 14, 30, 50, 75, 100, 200 and 365 days; adds a permanent +2%/day to the mining rate up to +50%; and, when broken, opens a paid recovery window.

Decay, not a wipe

Missing a single day without a Streak Freeze consumable reduces the streak by seven, not to zero — a long investment survives one slip. Missing two full days resets to one.

The repair window

For 24 hours after a break, the pre-break streak can be bought back for TVX, at a cost that scales with what is restored (600–12,000). The state remembers the exact streak lost and when, so the offer is precise. A resumed streak on a new day clears a stale offer.

The calendar

The Rewards tab shows the current month as a real calendar grid with a tick on every day the account checked in, renewing on the first. It exists to make the chain, and the cost of breaking it, physical.

§7Anti-abuse

Reputation

A 0–100 trust score, starting at 50. Ordinary play adds small amounts and pins an honest account at 100 within days. Two abuse signals subtract three points each: a replayed mutation, and an ad token belonging to another account. Reputation gates ad earning (below 20) and the early earn-multiplier tiers (40–85).

Two-layer idempotency

Every mutation carries a client-generated Idempotency-Key header, deduplicated against a mutations table so an honest retry returns the cached response. Independently, each ledger entry the engine produces has a deterministic idem string, and the ledger has a unique constraint on (user, idem). A mutation whose deterministic entries already exist is treated as a duplicate: current state is returned, no double credit, reputation dinged.

Server-authoritative claims

Session payouts are computed server-side from the recorded start time and locked-in rate, never from a client-reported amount. Day and week boundaries are computed in UTC on both sides so the client's optimistic preview and the server agree at midnight.

Sybil gate on referrals

A referred friend only counts toward the active-team boost once they reach Level 3 and have mined within the active window. A farm of one-session-a-day throwaway accounts is worth nothing. There is also no flat payout for a signup. The same Level-3 bar applies to crew members.

Gifted TVX can’t buy rank

Promo codes and program rewards add to the balance only — not to lifetime earnings, Level or the weekly leaderboard. Better pickaxes unlock by Level (Iron 3, Gold 8, Diamond 16, Obsidian 20), and Level only comes from TVX earned by playing, so a gift can’t be turned into a top pickaxe and a league win.

§8Architecture & trust

The rules of the economy exist four times, in lock-step. The Dart engine is the specification; a test suite is the contract; a TypeScript port runs on the server; an in-process mock runs the real Dart engine for local development. A parity test reads the TypeScript as text and asserts its load-bearing numbers still match the Dart side.

reward_engine.dart

Pure (state, action, now) → result. The spec.

engine.ts

Server port, runs in a Supabase Edge Function.

mock client

Runs the real Dart engine as an in-process server.

engine tests

300+ app tests + 200+ shared Dart↔TS parity checks.

Writes land through a single atomic RPC that upserts state, appends ledger rows with deduplication, and records the mutation — a claim and its referral side effects commit together or not at all. The client holds a durable offline queue: a mutation made without a connection applies optimistically, is queued with its idempotency key, and reconciles when the connection returns.

Remote configuration

Every tunable number lives in one versioned config blob fetched and cached by the client. Retuning the economy, or starting a limited-time event, is a new config row, not an app release. The current parameter set is in the field guide.

§9Governance & redemption

Economy parameters are set by the operator and can change to keep the system balanced; material changes are noted in-app. There is no on-chain governance and no community treasury today — §10 is the only scenario in which that could ever change.

Why redemption is gated on two conditions, not one

A redemption flow for gift cards is designed and built. It stays switched off until two independent conditions both hold, not one:

Operational readiness — a payout partner under contract, tax and identity setup for every jurisdiction served, and the compliance review real payouts require.
Ad-revenue readiness — verified rewarded-ad revenue reliably covers the redemption liability the ad-provenance rule below creates, with margin, measured over a sustained period — not a single good week.

The second condition exists because a redemption pool that pays out faster than its revenue backs it isn't a feature, it's a countdown. Gating on real, measured ad revenue — not a launch date, not a TVX balance, not demand — is what keeps "coming soon" from becoming a broken promise.

The ad-provenance rule

Once redemption is live, cashing out will require that at least 60% of the redeemed balance's lifetime provenance is ad-earned — traced from the same append-only ledger that already tags every entry by source (ad_reward, ad_double, session_claim, checkin, and so on). Earning, holding and spending TVX work exactly as they do today, with no new restriction anywhere in the app; the rule applies only at the redeem screen, to the balance being cashed out. In practice this means real payouts are backed by real ad revenue, by construction — a balance built entirely from the free loop can still be spent in the Marketplace exactly as before, it simply can't be redeemed for cash. Even once live, TVX is redeemed for a fixed catalogue — never cashed out at a floating price, and never traded.

No forward-looking value, today

Nothing in this document, the app, or its marketing should be read as a promise that TVX will have value on any specific date. Today it is a rewards-program balance and nothing else. §10 states the one long-term, fully conditional exception to that sentence, and states it with the same caution.

§10Token & long-term liquidity

This section describes a possibility under study, not a product, a date, or an offer. No token exists today. There is no presale, no allocation, no whitelist, and nothing to buy, stake or reserve. If that ever changes, it will only be after redemption (§9) has been running successfully, and only under the conditions below — stated now, in public, so they can't be quietly loosened later.

What actually breaks other "tap-to-earn" tokens

Two failure modes show up again and again in this genre. The first: an app spends years telling millions of people their balance will be worth something once a mainnet or a listing finally happens — a promise that keeps receding. The second, newer one: an app does list a token, fast, on the strength of hype alone, before real trading depth exists behind it — and the price collapses within days once the buyers who propped up the launch have no organic demand to sell into. Both are the same underlying mistake: treating a token as a way to create liquidity rather than something that requires liquidity to already exist. TAVEXA MINI's position is that this is a sequencing failure, not a crypto failure — liquidity has to exist before a token needs it, never the other way around.

The gate

A token would only be considered once all of the following hold, sustained for two consecutive fiscal quarters — not a single spike:

Proposed liquidity-readiness criteria · subject to legal and financial review before adoption
Condition	Why it's the bar
Redemption (§9) live and operating without a backlog	proves the ad-revenue-to-payout model already works with real money, at real volume
A large, genuinely active user base illustrative: 250k+ monthly active accounts	real trading depth needs real people, not a number on a pitch deck
Verified ad revenue at meaningful scale illustrative: $50k+ / month	the same discipline as §9 — liquidity backed by revenue, not by the token's own hoped-for price
Full legal review in every jurisdiction offered	a token can be a regulated security depending on how it's structured and sold — a legal question before it's a product one

The thresholds above are a starting proposal, published so the bar is public before it's ever close to being met — not a number we'll quietly move. They will be finalised with legal and financial counsel, not adjusted downward to hit a launch date.

What this is not

Not investment advice. Not an offer or solicitation to buy, sell or trade any security or digital asset, in this jurisdiction or any other. Not a guarantee that a token will ever launch, that it would have any particular value if it did, or that today's TVX would convert to it on any particular terms. Anyone telling you otherwise — in a chat, a group, or a "pre-sale" — is not us.

Phase 3 — Growth in progress now

Tavi waving hello to new players

Progression rebalance (Oct 2026) — every level now pays: the daily check-in grows with level (11 + 2 per level), the L11–L50 earn-multiplier tiers rise to ×2.4 → ×4.0 (each above the L6 streak tier), weekly missions +20% per 10 levels, the Weekly Pass +3% per level
Google Play listing rebuilt as a game (Simulation · Incremental), with a clearer title and description
Install-source measurement, so growth spend follows what actually brings players in
Meet Tavi — TAVEXA's robot mascot, now starring in the store art and a new vertical promo video
Version 1.0.1 live on Google Play — the new rewards shown correctly in-app, tidier leaderboard rows
A preview video on the Play listing and an official YouTube channel
Version 1.0.2 — the app, the store listing and this site all say the same thing: an idle mining game, TVX with no cash value
A regular cadence of limited-time events — Happy Hour every Friday, Bonus Ad Hour every Sunday
Version 1.0.3 — Crews: up to five players, a daily bonus when three or more mine (+30 / +40 / +100 each)
Eras & Vanguard: a community-wide mining bonus that steps down as the game grows (+100% in Genesis), and +5% forever for the first 250 miners to reach Level 5
105 badges in 18 families plus specials and hidden badges, each family tier paying 50–5,000 TVX; a badge score and titles
Public player profiles and a shareable profile card
Ambassador & Partner roles with in-app perks (+5% mining while active, named invite links), promo codes, invite skins at 5 / 25 / 100 friends

Every mechanic, number and moving part

The whitepaper explains why the economy is shaped the way it is. This is the operator's reference for what — each system, its exact values, the windows that trigger it, and where it surfaces in the app.

Three ways in, one balance

Everything the player does resolves to TVX in a single balance. TVX raises their Level from cumulative lifetime earnings. Three mechanics generate it; every timed window, streak and boost exists to pull the player back to one of the three.

Idle miningPassive, runs with the app closed. One tap to start, one to claim.
Rewarded adsWatch an ad, get TVX on top. The revenue engine, always optional.
Daily check-inA reward that grows with your level and builds a streak — the retention anchor.

↓ all credit the same append-only ledger ↓

Balance → Level

50-level curve off cumulative earnings. Milestones at 10 / 20 / 30 / 40 / 50.

Marketplace

Spend TVX on pickaxes, boosts and cosmetics. TVX has no cash value.

Idle mining session session_start / session_claim

Starting a session records a server-side start time and locks in the effective rate; the claim payout is computed by the server from elapsed time × locked rate, so a client can't forge the amount. Claimable once the session has run its full length (or half, with Instant Claim).

Idle mining — the numbers

A passive session that keeps earning while the app is fully closed. Nothing runs on the phone; a local notification fires when it's ready.

Length: 4 h default · 6 h with Extended Sessions · 8 h with Marathon Sessions
Base rate: 15 TVX / hr, before any bonus stacking
Lucky Strike: Server rolls a multiplier on claim — ×1.5 (8.5%), ×2 (3.3%), ×3 (1.2%). Revealed as a celebration.
Consumables: Double Mining (×2 payout) · Instant Claim (skips the back half only — no free loop)
Overclock: Sessions auto-restart on claim while a 24 h / 7 d Overclock is active
UI: Home mining card + full dial on Earn. A finished session flips the button to a pulsing CLAIM NOW · +amount.

Rewarded ads ad_complete / ad_double expanded

Google AdMob rewarded video, verified server-side (SSV) before TVX lands. Reward = base × earn-multiplier × boost × ad-streak × event × luck. Rate-limited, capped, and gated on reputation so it can't be farmed.

Base reward: 9 TVX, then multiplied
Min gap: 25 s between ads
Daily cap: Tiered by level: 15 → 20 → 25 → 30 → 40 → 50 (L1 / 10 / 20 / 30 / 40 / 50)
Reputation gate: Below 20 reputation, ad earning is blocked entirely
Boost window: Every 4th ad lights a 15-min +50% window on ad rewards
Lucky Ad new: Per-ad roll — ×2 (8%), ×3 (2%). The ×3 gets a jackpot dialog.
Ad Streak new: Consecutive days with ≥1 ad watched: +2% / day on ad rewards, capped +20% (10 days). Separate from the check-in streak; no freeze.
Ad Boost new: For 180 s after a credit, watch one more ad to add +60% to it. Countdown sheet on Earn; one boost per ad.

Daily check-in & streak checkin / repair_streak

A daily reward that grows with your level and also advances the check-in streak — a loss-aversion engine that grants a passive mining boost, unlocks milestone bonuses, and, if broken, can be bought back for a short window.

Reward: 11 + 2 × level TVX (13 at Level 1, 111 at Level 50), cooldown 6 h (up to 4 claims/day); the streak advances only on the first claim of a new UTC day
Streak bonus: +2% mining rate per streak day, capped +50% (25 days)
Milestones: Day 3 → +22, 7 → +60, 14 → +135, 30 → +340, 50 → +525, 75 → +900, 100 → +1,500, 200 → +3,400, 365 → +7,500 TVX
Streak Freeze: Consumable — covers exactly one missed day
Decay, not wipe: Miss a day with no Freeze → streak drops by 7 (not to zero); miss two full days → back to 1
Streak Repair: Within 24 h of a break, pay TVX (cost scales with what's restored, 600–12,000) to put it back. Offered on Home & Rewards.
Calendar: The Rewards tab shows the current month as a real calendar grid, a tick on every checked-in day, renewing on the 1st

How the mining rate stacks

Every bonus source is summed and applied once — never compounded — so each new source has a bounded, predictable marginal effect no matter what else is running:

rate = 15/hr × (1 + Σ bonusBps / 10000)

Additive rate sources
Source	Amount	Cap
Era (see below)	+100% → 0 by community size	locked at session start
Vanguard	+5%	first 250 to reach Level 5, permanent
Active ambassador / partner	+5%	while the role is active
Active referrals	+2% / active friend	+20% (10) + level & unlock
Check-in streak	+2% / day	+50% (25 days)
Level milestones	+5% each	+25% (all 5)
Equipped pickaxe	rarity + level	Obsidian maxed
Timed boost (Rush Hour / Overclock)	+50% / +25%	while active
Daily-goal boost	+10%	3 h window (5 h w/ Go-Getter)
Limited-time event	admin-set	event window

Daily goal → timed boost dailyGoalBoost

Do 4 daily activities (distinct tasks + check in + watch an ad + claim a session) and a 3-hour +10% mining boost lights. Deliberately a ticking window, not an all-day bonus — there has to be a reason to mine now. Completing it fires a celebration + a "boost is live" push, and a "30 min left" push before it ends.

Goal: 4 activities / day (flat)
Reward: +10% mining for 3 h — 5 h with the Go-Getter unlock
UI: Progress ring + segmented bar on Home & Rewards

Weekly Pass weekly_pass_claim new

A battle-pass-style track of 7 escalating rewards. Tier N unlocks once the account has checked in on N distinct days in the current ISO week; the tail tier is the "came back all week" payoff. Resets every week.

Ladder: 15 · 22 · 37 · 56 · 90 · 135 · 225 TVX, +3% per level (×1.3 at L10 … ×2.5 at L50)
Unlock: distinct check-in days this ISO week (max 7)
Claim: per-tier, once each; idem weeklypass:<week>:<tier>
UI: Horizontal scrubbable track card on the Rewards tab

Weekly missions mission_claim

Five weekly targets that reset each ISO week. Progress accrues passively as the player uses the app; the reward is claimed once the target is hit.

Mission catalog
Mission	Target
Ad Marathon	watch 40 rewarded ads
Steady Hand	check in on 5 different days
Task Master	complete 20 tasks
Session Streak	claim 5 earning sessions
Big Week	earn 1,500 TVX in the week

Limited-time events config.events[] new remote

Admin-toggled promo windows — e.g. "Weekend 2× Mining". Each is {key, title, kind, magnitudeBps, startsAt, endsAt}. kind: idle_rate adds to the mining rate alongside referral/streak; kind: ad_reward multiplies ad payouts. Toggling one is a new config version, no redeploy — the migration ships a ready SQL template. Home shows a gradient banner with a live countdown while an event runs.

Happy Hour: Fridays 17:00–19:00 UTC · mining sessions started in the window run +50% faster
Bonus Ad Hour: Sundays 17:00–19:00 UTC · rewarded ads pay +30%
Schedule: a weekly template in config (eventSchedule) is turned into dated windows by a cron job every Monday; a push goes out 10–15 minutes before each, and Home shows a countdown to the next one

Win-back push ladder lifecycle-dispatch new server cron

A pg_cron job (every 6 h) sweeps user_state.updated_at for accounts gone quiet 3 / 7 / 14 days and sends each one one personalised FCM push per stage — copy uses their real streak count, level and balance. A lifecycle_pings table guarantees a stage never fires twice. Reuses the existing Vault secrets + FCM sender; no new infra.

D3: "Your N-day streak is fading" / "your rig is idle"
D7: "A week of TVX, unclaimed — Level N miners are pulling ahead"
D14: "We kept your account warm"

Mystery Box mystery_box_open

A once-daily random TVX reward, unlocked at Level 3. The range widens at the same level brackets as the ad cap (L3–19: 11–22 … L50+: 60–120). Go-Getter grants a second free open per day; a Mystery Key consumable buys one more. A box is also paid automatically alongside each level milestone.

Levels & the earn multiplier

Level comes from cumulative earnings across a 50-level curve — fast to ~15, steep 15→30, a genuine long-haul 30→50. The earn multiplier scales every ad and reward; early tiers also gate on streak and reputation, later tiers on level alone.

Multiplier tiers
Multiplier	Requires
×1.00	base
×1.10	L2 · 40 reputation
×1.25	L3 · 3-day streak · 55 rep
×1.50	L4 · 7-day streak · 65 rep
×1.80	L5 · 14-day streak · 75 rep
×2.20	L6 · 21-day streak · 85 rep
×2.40 / 2.70 / 3.00 / 3.40 / 4.00	L11 / 20 / 30 / 40 / 50 — level only, each above the L6 tier

Level milestones (10 / 20 / 30 / 40 / 50) each pay a flat bonus (375 → 37,500 TVX), a Mystery Box, a permanent +5% mining rate, and an upgraded profile frame: Bronze → Silver → Gold → Platinum → Legendary. The earning-team cap also grows +5 every 10 levels.

Eras & Vanguard growth new

An Era is a mining bonus for the whole community, set by how many accounts have ever registered. It steps down as the game grows, so the earliest miners mine fastest. The bonus is added to the mining rate and locked in when a session starts.

Eras
Era	Registered miners	Mining bonus
Genesis	0 – 2,500	+100%
Dawn	2,500 – 10,000	+75%
Rise	10,000 – 50,000	+50%
Expansion	50,000 – 100,000	+30%
Horizon	100,000 – 250,000	+15%
Legacy	250,000+	—

The Vanguard are the first 250 miners to reach Level 5, numbered #001–#250 in the order they get there (accounts that never mine don’t take a spot). Each keeps +5% mining forever and a Mythic Vanguard badge. Every player also gets a badge for the Era they joined in. Home shows the current Era, how many spots are left in it, and your Vanguard number.

Reputation reputationDeltas

A 0–100 trust score, starting at 50. Honest play pins it at 100 within days; abuse signals bleed it. Purpose: a lightweight fraud throttle.

Gains: check-in +1 · ad +1 · session claim +2 · task +1 · streak milestone +3 · mission +4 · referral +3 (all clamp at 100)
Losses: −3 for a replayed mutation · −3 for a stolen / tampered ad token
Gates: ad earning stops below 20; the early multiplier tiers (L2–6) also need 40–85 reputation

Badges badges 105

18 families × 5 tiers (Bronze, Silver, Gold, Platinum, Diamond) plus 15 specials: 105 in all. The server checks them on every action; each family tier pays TVX once, the first time you reach it. Pin up to four to your profile showcase.

Tier rewards: Bronze 50 · Silver 150 · Gold 500 · Platinum 1,500 · Diamond 5,000 TVX
Badge score: tiers score 1 / 2 / 4 / 8 / 16; titles: Prospector → Excavator (25) → Deep Miner (75) → Gem Hunter (200) → Mine Lord (450) → Legend of the Deep (800)
Specials: Vanguard, the Era you joined in, Launch Month 2026, Comeback, Perfect Week, Senior and Elite Ambassador — plus hidden badges whose conditions stay secret

Badge families · tier I → V
Family	Measured by	Tiers

Crews crew new server

A crew is a small group — up to 5 players. Create one and share its CRW- code, or join with a friend’s. On any UTC day that 3 or more members claim a mining session, everyone who mined collects the Crew bonus. It is paid automatically the next time you open the app, and topped up if more of the crew mine later that day.

Bonus: +30 each at 3 miners · +40 at 4 · +100 when all 5 mine (Full Crew)
Who counts: members at Level 3+ — lower levels can join and play, but don’t count yet
One crew: one crew at a time; after leaving or being removed, 24 h before joining or starting another
Owner: the creator can remove members; if the owner leaves, the longest-standing member takes over
Crew streak: consecutive days the crew reached 3 miners
Reminder: at 14:00 UTC, members who haven’t mined get one nudge if their crew already has (under the Mining alerts setting)

Player profiles /u/:name new

Tap any name on the leaderboard or in your league, or long-press a chat message, to open that player’s profile.

Shows: username, join date, level, badge score and title, the four pinned badges, best streak, equipped pickaxe, frame and chips: Vanguard number, Era, Ambassador or Partner role, invite title
Never shows: email, balance or anything account-related
Share card: Profile → “Share my profile card” makes an image to post anywhere

Referral & Earning Team referral_redeem

Invite friends with a code. There is no flat payout for a signup (that used to reward spam). The referrer earns two ways: a one-time activation bonus, and a passive mining boost that scales with how many friends are currently active.

Referee bonus: 55 TVX, one time, for the person who was invited
Activation bonus: when a friend reaches Level 3 (reputation ≥ 40): +150 for the inviter (up to 10 friends) and +50 for the friend — once each
Invite link: tavexa.app/i/<code> — carries the code through Google Play’s install referrer, so it is applied at sign-up
Nudge: the team screen shows each friend’s level and a one-tap “your rig is idle” message for anyone not mining
Ad earnings: never shared - a friend's ad rewards are theirs alone (the old 10% ad rev-share was removed in Oct 2026)
Active-friend boost: +2% mining rate per friend who mined in the last 24 h and is Level 3+
Team cap: starts at 10 · +5 per 10 account levels · +10 with the Bigger Team unlock
Invite rewards: friends who reach Level 3 unlock pickaxe skins and a title: Recruiter (5), Captain (25), Commander (100)
Share task: sharing your invite pays 50 TVX once a week

Global Chat & Weekly Leaderboard

Chat — one room for everyone, keyed to the username, ~48 h retention, poll-based over the API seam. Links and promo text are blocked; 1.5 s send cooldown. Name colour is a cosmetic bought from the store — an owned collection you switch between for free.

Leaderboard — top 100 by weekly TVX, resets each ISO week. A compact Home social strip new shows your rank, the gap to the spot above, your streak and how much of your team is active — and taps through to the full board.

Weekly leagues league new server

The global top 100 is out of reach for a new player, so everyone also races a small league: a cohort of up to 30 on the same tier, ranked by this week’s TVX. Open the League tab on the Leaderboard screen and the server places you. On Monday the top fifth of each group moves up a tier, and anyone who mined nothing drops one.

Tiers: Bronze → Silver → Gold → Platinum → Diamond → Master → Grandmaster → Legend
Group size: up to 30; the oldest open group fills first — no invented players, a quiet league just shows who is in it
Promotion: top 20% of the group (at least 1, at most 5) with TVX > 0 - Silver and above also need an active team (see below)
Team requirement: from Silver onward, promotion also needs active team members (mined in the last 24h, level 3+): Silver→Gold 5, Gold→Platinum 10, Platinum→Diamond 15, Diamond→Master 20, Master→Grandmaster 25, Grandmaster→Legend 30. Short on the requirement? The rank isn’t wasted - it passes to the next-best player who has it.
Demotion: zero TVX all week, on Silver or above
Rollover: Monday 00:20 UTC, with a push or Telegram DM for anyone who moved

Ambassador & Partnership program partner-apply new server

An in-app application form (Profile → "Ambassador Program", first in the list). Two kinds — represent your country or partnership — each with a thorough, decision-ready field set (main platform + link, audience band, languages, weekly commitment, experience; or company + website + role + partnership type). Only decision-critical fields are required.

Storage: partner_applications table — review, then set status and reviewer_note
Email: best-effort notification with the full form when the mail keys are set
Tracking: "My applications" screen — each submission with a status chip (Submitted / In review / Accepted / Declined) and any team note
Roles: Scout, Ambassador, Senior and Elite Ambassador; Partner Bronze, Silver and Gold
Perks: +5% mining while the role is active, a role chip on the profile, rewards for real results, and a named invite link (tavexa.app/i/name) for partners
Honours: Senior and Elite Ambassadors keep a badge and an Ambassador frame for good; Elite also unlocks a pickaxe skin

Store catalog store_buy

Everything buyable with TVX that isn't a pickaxe. Pickaxe purchases and store spends are the only actions that subtract TVX. Three consumable / timed keys rotate onto a −25% daily deal.

Store items · price in TVX

Chat name colours ×12	cosmetic	1.4k–10.8k	owned collection, free to switch

Pickaxes pickaxe_buy / _upgrade / _equip

Mining tools bought once with TVX, then upgradable through levels. The equipped pickaxe's bonus folds into the mining-rate stack. Wood is owned from the start. Each pickaxe unlocks at a player level, and levels only come from TVX earned by playing, so gifted TVX (promo codes, programme rewards) can't buy a top pickaxe early. A pickaxe you already own can always be upgraded.

Pickaxe catalog
Pickaxe	Rarity	Unlocks at	Price
Wooden Pick	common	Level 1	— starter
Stone Pick	common	Level 1	450
Iron Pick	uncommon	Level 3	2,700
Gold Pick	rare	Level 8	10,800
Diamond Pick	epic	Level 16	40,500
Obsidian Pick	legendary	Level 20	135,000

Upgrade cost scales price × 0.6 × currentLevel (min 200). Also on the Marketplace: sponsored / partner tasks that submit a link or handle for manual approval, then pay a flat credit.

Architecture at a glance

The rules of the economy exist four times, in lock-step. The Dart engine is the spec; a test file is the contract; the TypeScript port and the in-process mock must match it — a parity test diffs their load-bearing numbers.

reward_engine.dart

Pure (state, action, now) → result. The spec.

engine.ts

TS port for the Supabase Edge Function.

mock_api_client.dart

Runs the real Dart engine as an in-process "server".

economy_engine_test.dart

Unit tests + a shared Dart↔TS parity-vector suite.

Client seam: ApiClient: DioApiClient (HTTP) ↔ MockApiClient. One line swaps local → global.
Gateway: EconomyGateway — cached state, optimistic local engine apply, server reconcile, a durable offline Outbox, 2-layer idempotency (HTTP key → mutations; ledger idem → append-only ledger_entries)
Server: Postgres (no direct client access — every call goes through service-role Edge Functions) + Deno Edge Functions (51) + an atomic apply_writes(jsonb) RPC + economy_config remote-config (v32)
Auth: guest / email + password / Google — all mint a Supabase session
Notifications: flutter_local_notifications (mining-ready, streak-risk + a last-chance alert 1 h before the deadline, boost-expiring, a come-back nudge after ~60 h idle) + server-side D3/D7/D14 win-back pushes + FCM for broadcasts + Telegram DM mirrors (streak alert, come-back, referral and league-promotion nudges) for linked accounts; white bolt status-bar icon
Persistence: Hive, stored as plain JSON maps (not typed adapters) for backend portability
Time: all day / week boundaries in UTC so client and server agree

Tunable numbers config v32

Every economy constant lives in one remote-config blob, fetched and cached by the client. Retuning is a new row in economy_config — no app release.

FAQ

Is this crypto? Can I withdraw money?

No. Today there is no tradable token and no blockchain, and TVX can’t be withdrawn or cashed out — it’s an in-game score with no monetary value, spent in the Marketplace.

Does mining really run while the app is closed?

Yes. The session records its start time on the server; the payout is computed from elapsed time when you claim. Nothing runs on your phone, and you get a notification when it's ready.

Do I have to watch ads?

No. Ads are optional and pay TVX on top of everything else. The full loop works without them — you just earn slower.

What does it collect about me?

A username (optionally an email), a push-notification token, and your in-app economy data. Rewarded ads use Google AdMob, which processes an advertising identifier. Full detail in the Privacy Policy. Nothing is sold.

How is it kept fair?

Server-authoritative payouts, deterministic idempotency on every write, a ledger replay guard, a reputation-based throttle, and a level-and-activity gate on referral rewards. See whitepaper §7.

Inside TAVEXA MINI: a tour of every screen

Five tabs on the bottom, a dozen systems underneath, and exactly one balance that all of them feed. Here's what each screen is actually for.

TM TAVEXA MINI Team September 20266 min read

Open the app and you land on Home — your rig's dashboard. The mining ring tells you what's running and what it's worth right now; if a limited-time event or a boost is live, it's the first thing you see, not something buried three taps deep. A social strip shows your leaderboard rank and how far the next spot up actually is, in TVX, not vibes.

None of these screens exist to keep you scrolling for its own sake. Rewards groups everything you can do today; Wallet answers "where did my balance come from"; Marketplace is the only place it can go. The whole shell is built as a StatefulShellRoute, so switching tabs never loses your scroll position or resets a running countdown — the mining ring on Home keeps ticking whether you're looking at it or three tabs away.

Systems feeding one balance

Why nine screens instead of three

The easy version of this app is one button that says "claim." We built nine screens instead because each one answers a different question a real player actually asks: what am I earning right now (Home), how do I earn faster (Earn), what's left to claim today (Rewards), where did all this come from (Wallet), what can I spend it on (Marketplace), who's helping me and who am I helping (Earning Team), is anyone else here (Chat, Leaderboard), and who am I in this (Profile). Cut any one of those and a real question goes unanswered — that's the test we used to decide what earned a tab and what got folded into a detail screen instead.

A rewards app with a dozen systems and no map is just a dozen confusing systems. The tour above is the map.

Five hooks that make it hard to put down (the honest kind)

"Engagement" has a bad reputation, mostly earned. Here are the five mechanics actually doing the pulling in TAVEXA MINI, and why we're comfortable naming every one of them out loud.

TM TAVEXA MINI Team September 20265 min read

Every one of the five mechanics below is engineered to make you want to open the app again soon. That's not a confession — it's the job description of any rewards product. What matters is whether the mechanic still looks fine once you understand exactly how it works. Read each one as if we're explaining it to you before you've used it, because that's genuinely how we designed it.

1

Every 4th ad

The Boost Window

A real, visible 15-minute window where ad rewards run +50%, counting down on the Earn tab. The pull is exactly as strong as the number on screen — no hidden multiplier, no "sometimes it's better, you'll never know when."

2

Resets every Monday

The Weekly Pass

Seven tiers, one unlocked per distinct check-in day. The pull isn't "grind harder today," it's "there's a reason to open the app tomorrow specifically" — a hook that rewards a habit, not a session length.

3

180-second window

Ad Streak + Ad Boost

Consecutive ad days add +2% each, up to +20%. Watch one ad and a countdown opens to add 60% to that exact reward with one more. Both expire on a real clock, both pay out the stated amount — no escalating requirement, no bait-and-switch.

4

One config row

Limited-time events

A "Weekend 2× Mining" banner, when one runs, shows up on Home with a countdown and nowhere else to hide it. It's honest about being temporary because it's built to literally stop existing when the timer hits zero.

5

D3 · D7 · D14

Win-back pushes

Go quiet for three, seven or fourteen days and we send exactly one push per stage, built from your actual state — your real streak, your real level. Not "we miss you." A nudge built from truth, sent once, not a drip campaign.

Every hook on this list tells you the truth about what it does. That's the whole design brief.

What's deliberately not on this list

No countdown that resets itself if you don't act (a fake-scarcity classic)
No loot box — every reward you can see the odds or the fixed value of before you commit
No streak mechanic that punishes harder than it rewards (see the streak-repair piece)

Engagement mechanics aren't inherently manipulative. The line is whether the player, shown exactly how the mechanic works, would still feel fine about it. Every one of the five above passes that test, on purpose.

A day in the life of a TAVEXA MINI miner

Not a hypothetical persona — the exact sequence of taps and numbers a genuinely active account sees over one ordinary day.

TM TAVEXA MINI Team September 20264 min read

This isn't a hypothetical persona built for a pitch deck. It's the literal sequence of screens, taps and numbers a real, moderately active account moves through on an ordinary weekday — six separate moments, none of them requiring more than a few seconds of attention.

7:12

Home

The overnight session lands

A notification: the session is done. The ring is full, and the button has already flipped to a pulsing CLAIM NOW · +140. One tap. A shower of coins animates toward the balance, and a fresh session starts on its own — Overclock is still active from last week's purchase.

7:14

Rewards

Check-in, streak day 13

+11 TVX, and the streak strip ticks over to day 13 — +26% now folded permanently into the mining rate. The Weekly Pass card shows day 3 of 7 lit, one more tier waiting.

12:30

Earn

A lunch-break ad, and a double

One rewarded ad — the fourth today, so the Boost Window lights, +50% on ad rewards for 15 minutes. A sheet slides up: Boost it?, a 180-second ring counting down. One more ad. +24 instead of +15.

18:45

Earning Team

Checking the rate stack

Two friends mined today; the rate breakdown shows Team at +4%, next to Streak at +26% and Pickaxe at +12%. The whole stack, laid out, sits at 275% of base — exactly why the effective rate reads what it reads.

21:50

Closing the day out

#482 this week, 160 TVX from #481. Global Chat is mid-conversation about who's opened a Diamond pick yet. Not yet — the Marketplace screen shows exactly how close.

None of this required a single decision that felt like it was being made for you. Every number on every screen was one you'd already seen coming.

That's the actual design goal behind all of it: a day where the app is worth opening five or six separate times, and every single one of those visits pays out something real and legible, whether it's 11 TVX or 140.

Feature Tour

The pickaxe system: a small RPG bolted onto real rewards

Six tools, a rarity ladder, and an upgrade curve — the one part of TAVEXA MINI that plays like a collection game, sitting directly on top of the mining rate that actually matters.

TM TAVEXA MINI Team September 20264 min read

Everyone starts with a Wooden Pick, free, day one. From there the ladder climbs through Stone, Iron, Gold, Diamond, to Obsidian — common to legendary, exactly the rarity vocabulary you'd expect from a loot-driven game, except every step is bought outright with TVX you earned mining, not with a currency you had to buy.

WOOD

STONE

IRON

GOLD

DIAMOND

OBSIDIAN

Buying a pickaxe is only step one. Each one upgrades through levels afterward, at a cost that scales with price × 0.6 × currentLevel — cheap early, deliberately real by the time you're pushing a Diamond pick toward its cap. The pickaxe you have equipped folds its bonus directly into the mining-rate stack described in the rate-math post; it isn't cosmetic, it's one of the five real levers on your effective rate.

Three things to actually do with a pickaxe

Collect

Six pickaxes, one visible rarity ladder, starting piece free.

Upgrade

A real cost curve tied to the pick's own level, not a random gate.

Skin it

Six cosmetic skins recolour the equipped pick without touching the rate.

Skins — six of them, priced 2,700–13,500 TVX — sit entirely apart from the upgrade ladder. They exist so spending TVX always has somewhere satisfying to go, even once your rate is already where you want it, and buying one never touches your actual earn rate one way or the other.

A collection loop only feels good when the thing you're collecting also does something. Ours mines faster.

The Marketplace tab is also where sponsored partner tasks live — follow a channel, submit a link, get reviewed, get paid — a completely separate reward stream that happens to sit next to the pickaxe shelf because they're both "spend a minute here, come back with something."

Global Chat & the Leaderboard: the social heartbeat

An idle-mining app doesn't need a social network. It needs one room and one scoreboard, both honest, and both worth glancing at more than once a day.

TM TAVEXA MINI Team September 20264 min read

Global Chat is exactly one room — not per-country channels, not a wall of servers to pick between. Everyone lands in the same conversation, keyed to a username, with roughly 48 hours of history so it stays a live conversation instead of an infinite scroll. Links and obvious promo text get filtered automatically, and a 1.5-second send cooldown keeps it from turning into a wall of spam the moment it gets busy. The one cosmetic touch: a name colour, bought from the store, from a collection you own and can switch between for free once purchased — small, but it's the one place your Marketplace spending shows up to other people.

The Leaderboard is just as deliberately simple: top 100 by TVX earned that week, resetting clean every ISO week. Nobody camps the top forever, because the board itself forgets last week ever happened the moment a new one starts. A compact social strip on Home shows your current rank and the exact TVX gap to the account above you — not a vague "you're doing great," a real number you can decide to close today.

One room

No servers to pick, no channel to find — everyone lands in the same place.

~48h history

Long enough to catch up, short enough to stay a live conversation.

Weekly, clean reset

Top 100 by TVX, no account camping the top forever.

Why we kept both small

Together, chat and the leaderboard are the only two screens in the app where you're looking at other people instead of your own numbers. We kept both of them small on purpose: big enough to feel alive, small enough that a person who opens the app once a day for the mining loop never feels like they're missing a second app's worth of social obligation layered on top. Neither one has notifications of its own, unread badges, or a reason to pull you in beyond what's actually there when you look.

A leaderboard that never resets rewards whoever showed up first. A leaderboard that resets weekly rewards whoever showed up this week — which is a much more interesting group of people to compete against.

Policy

Trust before liquidity

Every rewards app eventually gets asked "so when can I cash out?" We have a real, staged answer — and we're publishing the exact conditions for every stage of it now, before any of them are close to being met.

TM TAVEXA MINI Team September 20265 min read

The honest answer, today: TVX is an in-app balance with no cash value. It raises your Level, unlocks milestones, and that's it right now. There's a real plan for what comes after "right now" — two stages, each with its own hard, public gate — and this post is that plan, in full, including the parts that are years away and might not happen at all.

● What's live today

An in-app balance

No exchange, no floating price, no promise the balance is worth more tomorrow than today.

● What's planned, staged

Redeem, then maybe liquidity

A fixed-catalogue gift-card redeem first (whitepaper §9); a conditional token discussion only after that (§10).

We looked hard at how this genre usually goes, because we didn't want to repeat either of its two standard mistakes. The first: an app spends years telling millions of people their mined coins will be worth something once a mainnet finally launches — a promise that keeps receding and never quite arrives. The second, more recent one: an app does ship a token, fast, riding pure hype into a listing before any real trading depth exists behind it, and the price collapses within days once the users who propped up the launch have nothing organic to sell into. Both fail for the same reason — treating a token as the thing that creates demand, instead of something that needs real demand to already exist. We're not interested in either version.

A rewards program that names its conditions before it needs to can't quietly move the goalposts later — the goalposts are already public.

So here's the actual, two-stage plan, stated as plainly as we can state it, with every gate a matter of measurable fact rather than a vibe or a launch date:

Stage one: redemption, gated on ad revenue (whitepaper §9)

Gift-card redemption turns on once a payout partner and per-region legal/tax work are done, and verified rewarded-ad revenue reliably covers what redemption would pay out, with margin, over a sustained period — not a single good week. On top of that, cashing out will require that at least 60% of the redeemed balance's lifetime provenance is ad-earned, traced straight from the ledger. Spending and earning TVX doesn't change at all; the rule only applies at the redeem screen. This is what keeps the payout pool solvent by construction, instead of by hope.

Stage two: a token, gated on real scale (whitepaper §10)

Only after stage one has run cleanly for a while would a token even enter the conversation — and only once there's a large, genuinely active user base and verified ad revenue at real scale, sustained for two consecutive quarters, plus a full legal review in every jurisdiction it would touch. No presale, no whitelist, no allocation exists today, and none will be announced before those conditions are actually met. The exact thresholds are in §10, published now specifically so they can't be revised downward later just to hit a launch date.

What this costs us

Some players want a payout today and will go find one elsewhere. We accept that. The trade is a product that can be honest about its own economics and its own timeline, instead of one that has to keep a story going to survive. If either stage ships, it'll be because the numbers and the paperwork are actually there, not because enough people asked.

What would actually move either gate

Nothing about demand, on its own, moves either one. For redemption: a signed payout partner, completed legal review per region, and ad revenue that measurably covers the liability. For a token: everything in §10's table, all at once, sustained, reviewed by counsel. Until then, this post and the whitepaper are the entire plan — not "we heard you," which isn't the same thing as "it's compliant," and not a date, because we don't have one to give.

What an independent audit found

We asked for an outside pass at TAVEXA MINI's backend, database and economy, with no say over what it looked at and no veto over what got published. Here's what came back, and what we did about it.

TM TAVEXA MINI Team September 20266 min read

In September 2026 we commissioned an independent technical and economic review of TAVEXA MINI — the backend, the database, the client, and the economy's own numbers. We're not naming the reviewer; what matters here is the method and the result, not the byline. The scope: read-only queries against live production data, a full pass over the source, and re-verification of every claim before it went in the report. Nothing was changed or fixed during the review itself, and no secret or credential was written into it — only where each one lived, for us to rotate.

● Before

Pre-launch, untested by anyone outside the build

A single-developer codebase that had never been read by someone trying to find where it breaks.

● After

Findings fixed, published, and re-checked

Every item below either shipped a fix the same week or is tracked, by name, on the public roadmap.

We're publishing this because the alternative — fixing things quietly and saying nothing — is exactly the kind of silence we've said elsewhere we'd rather not practice. A report you never see protects nobody but us.

What we found and fixed

A race condition in how balances were written. Two actions landing at nearly the same moment could overwrite each other instead of both counting. Fixed with optimistic-concurrency writes: a conflicting write now retries against the current state instead of silently clobbering it.
A database table growing without bound. Every request was logging its entire response for replay-safety, forever. Slimmed to just what idempotency actually needs, with an automatic retention sweep.
Database permissions broader than any table needed. Default access grants would have made a future table world-writable by mistake, not on purpose. Locked down to exactly what each table's own rules require.
No way to delete your account. Now built end-to-end — in-app, and by email — and required reading before we could accept this size of an app in any real app store.
No moderation tools in Global Chat. Reporting existed; blocking another user didn't. Added, along with a review queue for reported messages.
No age gate. A rewards app with optional ads and open chat needs one regardless of store policy. Added at sign-up, 16+.
No error or crash visibility at all. If something broke for a real user, we'd have had no way to know. Built a first-party analytics and error-reporting pipeline before we needed it, not after.
The redemption math didn't hold up. Organic earning paid out more, per day, than rewarded ads could realistically fund — a problem every app in this genre eventually hits and few name out loud. This is the one we're proudest of not hiding: the Sep 2026 economy rebalance and the ad-earned-share requirement in whitepaper §9 exist directly because of this finding, not despite it.

What's still open, on purpose

We're not going to pretend everything on the list is closed. Rewarded-ad verification enforcement is being hardened before it's switched fully on — tracked as its own line in Phase 2. A handful of items are ours to do by hand rather than ship in code: rotating a set of development secrets, and finishing the production app packaging a real store listing requires. None of it is hidden because none of it is finished — it's on the roadmap because it isn't.

The value of an audit isn't the list of things that were wrong. It's whether the list is still readable a year later, next to what actually happened about it.

Why we keep doing this

We don't think one review makes a product trustworthy forever. What we're committing to is the pattern: keep asking someone to try to break it, keep publishing what they find, and keep this specific post open to being wrong later if a future review contradicts it. That's a harder standard than "audited," and it's the only one we think is worth anything.

Why we add bonuses instead of multiplying them

An early build of the mining rate multiplied every bonus together. It looked fine with two bonuses active. It looked insane with six.

TM TAVEXA MINI Team September 20265 min read

Here's the version we almost shipped: a +50% streak bonus, a +20% team bonus, a +25% pickaxe bonus and a +50% timed boost, all multiplying the base rate in sequence. Add a fifth bonus and the number stops being something a player can estimate in their head. That's the actual problem: not that the number gets big, but that nobody — including us — can look at their own account and predict what happens when the next bonus source is unlocked.

● What we almost shipped

50.6/hr

Four bonuses multiplied in sequence — a 238% jump from sources that sound modest individually.

15 × 1.5 × 1.2 × 1.25 × 1.5

● What actually ships

36.8/hr

The same four sources, summed once — a predictable, legible 245% of base.

15 × (1 + 1.45)

The fix was to stop multiplying and start adding, in basis points, once:

rate = 15/hr × (1 + Σ bonusBps / 10000)

The same five sources maxed out — streak, team, level milestones, pickaxe, a timed boost — sum to roughly 275% of base, not 800%+. More importantly, every source's marginal contribution stays exactly what it says on the label: a +2%-per-day streak bonus adds 2% each day, forever, whether you have zero other bonuses running or all of them.

Compounding bonuses

An economy where a player can compute their own ceiling on a napkin is an economy that feels fair, even to the player who hasn't maxed it out yet.

The part we didn't compromise on

We kept exactly one exception in mind while designing this, and then didn't use it: Lucky Strike and Lucky Ad multipliers (×1.5 to ×3, rolled server-side on a single claim) stay multiplicative, because they're a one-shot dice roll on a single payout, not a standing rate modifier. Multiplying a one-time roll doesn't compound into anything — it resolves and it's done. The rule we actually follow is narrower than "never multiply": it's "never let two standing bonuses multiply each other." Everything in the whitepaper's rate table follows from that one line.

Designing a streak you don't dread breaking

Loss aversion is real and it works. It's also the mechanic most responsible for making people feel bad about apps they otherwise like.

TM TAVEXA MINI Team September 20264 min read

The classic version, which you've almost certainly used, is a single missed day wiping a streak counter back to zero. It's effective — nobody wants to lose a 40-day chain — and it's also the single most common source of "I deleted the app after I missed one day and lost everything" reviews across the genre. We wanted the retention pull without inheriting that specific resentment.

Three decisions got us there:

Decay by 7, not to zero

A missed day with no Streak Freeze costs seven days. A 40-day run drops to 33.

A 24-hour window

Buy the exact days back, cost scaling with what's restored (600–12,000 TVX).

A real calendar

Not a bare counter — the month, the ticks, the ninth actually looks like the ninth.

Max streak bonus

Days to reach it

A number going up is an abstraction. A calendar with gaps in it is a memory.

What we chose not to do

We didn't add a way to buy an unlimited streak-freeze subscription, and we didn't make the repair cost trivial. Both would have quietly turned "don't break the chain" into "pay to never think about it," which defeats the point of having a streak in the first place. The mechanic is supposed to reward showing up, not reward spending enough to skip showing up.

What happens if you miss two days

The seven-day decay only covers a single slip. Miss two full days in a row with no Freeze active and the streak resets to one — the repair window still opens, but it's now repairing from a much smaller base, which is the honest trade-off of a forgiving-once system: it forgives once, not indefinitely.

Fighting ad fraud without punishing honest players

The easy version of ad-fraud prevention treats every player like a suspect. We wanted a system that mostly forgets you exist — right up until you do something that looks like abuse.

TM TAVEXA MINI Team September 20265 min read

Every account starts at 50 reputation, on a 0–100 scale. Ordinary play — a check-in, an ad watched, a session claimed, a streak milestone hit — nudges it up by one to four points, clamped at 100. Within a few days of normal use, an honest account sits at the ceiling and never thinks about the number again. That's the part we care about most: the score should be invisible to everyone who isn't doing something wrong.

Two things pull it down, and only two: a replayed mutation (the same write, resent as if it were new) and an ad token that belongs to someone else's account. Each costs three points. Below 20 reputation, ad earning stops outright; between 40 and 85, the early earn-multiplier tiers stay locked. That's the entire penalty surface — no shadow bans, no silent throttling triggered by "unusual" but legitimate play patterns like watching several ads in a row after a long break.

Penalty triggers, total

A fraud system that occasionally flags real players isn't a fraud system with a bug. It's a fraud system with the wrong design.

The boring infrastructure doing the real work

Reputation catches patterns; three other mechanisms catch the individual events:

Idempotency keys

A retried request returns the cached result instead of a second credit.

Ledger replay guard

Every entry has a deterministic id; the ledger enforces uniqueness on it.

Server-side verification

An ad credit only lands after AdMob's own callback confirms the impression.

None of this requires the player to notice it exists, which is exactly the point — a fraud layer that shows itself has usually already failed at its actual job.

Four engines, one truth

The scariest bug class in a rewards economy isn't a crash. It's the client and the server quietly agreeing on the wrong number.

TM TAVEXA MINI Team September 20265 min read

The client needs to show you something the instant you tap "claim," before a round trip to the server completes — that's the whole point of an optimistic UI. But the server is the only party allowed to actually decide what you earned. Those two facts are in tension unless the client's guess and the server's truth are computed by rules that are provably the same rules. Our answer was to stop treating that as a documentation problem and start treating it as a lock-step problem.

reward_engine.dart

Pure (state, action, now) → result. The specification, not a description of it.

engine.ts

A line-for-line port that runs inside the Supabase Edge Function — the actual authority.

mock client

Runs the real Dart engine in-process, so local development never touches a fake ruleset.

parity test

Reads the TypeScript source as text and asserts its load-bearing numbers still match the Dart side.

The interesting piece is the last one. Most cross-language ports drift silently: someone tunes a constant in one file, forgets the other, and the bug sits there until a support ticket surfaces it weeks later. Our parity test doesn't run the TypeScript — it reads it as a string and greps for the numbers that matter (a rate constant, a cap, a formula's shape) and fails the build the moment either side changes without the other. It's a blunt instrument on purpose. Blunt instruments are the ones you don't have to remember to use correctly.

Parity diff, Dart vs TS

Silent drift tolerated

We didn't want "the client and server agree" to depend on two engineers remembering to update the same number in two files on the same day.

Why a mock server instead of a fake one

The other unusual choice: local development doesn't run against a simplified stand-in economy. The mock API client runs the actual Dart engine in-process, so a feature built and tested entirely offline behaves identically to production the moment it's pointed at the real backend. One line swaps the client implementation. Nothing about the rules changes.

What this actually catches in practice

It's caught real bugs, not hypothetical ones — a streak-repair calculation that briefly disagreed between the Dart and TypeScript sides during the Phase 1 push shipped fine specifically because the parity test failed the build before it reached a device. That's the entire value proposition in one sentence: the boring test that fails loudly in CI is cheaper than the interesting bug report that arrives from a real account three weeks later.

The Weekly Pass, and why it isn't a battle pass

It has tiers, a ladder of rewards, and a reveal moment at the end — the shape of a battle pass. The incentive underneath it is the opposite of one.

TM TAVEXA MINI Team September 20264 min read

A battle pass, in the genre that popularised the term, rewards hours logged: grind a season's worth of matches or missions, or pay to skip the grinding. Ours rewards a much smaller, much more specific thing — showing up on a distinct day. Tier N of the seven-tier ladder unlocks the moment you've checked in on N different days in the current ISO week. There's no way to grind it open faster by playing longer in a single sitting, and there's no way to buy a tier you haven't earned.

DAY 1 · 15

DAY 2 · 22

DAY 3 · 37

DAY 4 · 56

DAY 5 · 90

DAY 6 · 135

DAY 7 · 225

That constraint was intentional. The check-in streak already rewards consecutive days; the Weekly Pass rewards the same behaviour on a shorter, resetting clock, so a broken long streak isn't the only thing worth coming back for — a fresh Monday is too. The tail tier, at 300 TVX, is specifically the "came back all seven days" payoff, sized to be worth noticing without being worth changing your week around.

The reward for showing up should scale with showing up, not with how long you're willing to sit there once you have.

What an Ambassador actually does

The application form is longer than most in-app forms get away with. That's deliberate — we'd rather ask for detail up front than review a form that tells us nothing.

TM TAVEXA MINI Team September 20263 min read

The Ambassador & Partnership program has two tracks, and the form branches depending on which one you pick.

● Track 1

Represent your country

Your main platform and a link to it, an audience-size band, the languages you post in, how many hours a week you can realistically commit, and any relevant experience — the fields a reviewer actually needs to say yes or no.

● Track 2

Partnership

A company name, a website, your role there, and the kind of partnership you're proposing — enough for a reviewer to understand what working together would actually look like.

After you submit, the application lands in a review table with a status — Submitted, In review, Accepted, Declined — that you can track from a "My applications" screen in-app, along with any note a reviewer leaves. We don't auto-approve either track; a person reads every submission.

We'd rather tell an applicant "not yet" honestly than tell them "yes" and mean "maybe, we'll see."

What we don't promise

Acceptance isn't a job offer, a guaranteed payment, or a promise of a specific reward — the program is still early, and we're upfront about that in the form itself. What it is: a real, tracked way to say "I want to help this grow in my country" or "I want to explore working together," and to have that go to an actual person instead of a support inbox.

Why the form doesn't ask for less

A short form is easy to fill out and impossible to act on. Asking for an audience-size band and a weekly-hours commitment up front means a reviewer can say "yes, and here's what to expect" on the first pass, instead of a back-and-forth of follow-up questions that quietly discourages everyone except the most persistent applicants — which is exactly the opposite of who a program like this should select for.

Phase 1 shipped: what changed and why

Foundation was Phase 0 — the economy, the auth, the core loop. Phase 1 was about giving that loop a reason to pull you back on a given hour, not just a given day.

TM TAVEXA MINI Team September 20264 min read

Phase 0 was the foundation — the economy, the auth, the core loop, the anti-fraud plumbing. Phase 1 was about giving that loop a reason to pull you back on a given hour, not just a given day. Here's what actually shipped, and what we fixed alongside it.

1

Ads

Lucky Ad, Ad Streak, Ad Boost

A roll on rewarded video (×2 about 8% of the time, ×3 about 2%), a streak that stacks +2%/day to +20%, and a 180-second window to add 60% to any single credit.

2

Retention

The seven-tier Weekly Pass

One tier unlocked per distinct check-in day, resetting every ISO week — the design rationale is its own post.

3

Config-driven

Limited-time events

A promo window that lights from a new config row, not a code change — and disappears the same way when the timer ends.

4

Server cron

The win-back push ladder

Personalised D3 / D7 / D14 nudges built from each account's real streak, level and balance — not a generic "we miss you."

5

Quiet fixes

The stuff nobody sees in a changelog

A monthly calendar rebuild of the streak strip, a Dart↔TS streak-repair parity fix, a daily-goal correction (five was quietly unreachable; it's four now), and a real notification icon after a placeholder shipped by mistake.

6

Quiet fixes alongside

2

Phases complete

The features that show up in a changelog and the bugs that get fixed alongside them are usually the same amount of work. Only one of them makes it into the announcement.

What's deliberately still missing

No hint, anywhere, that TVX becomes money or crypto later. No multi-level referral commissions — a referrer earns from the friends they invited directly, not from a downline. No forced or deceptive ad gating. Each of those is a fast way to grow a number in a spreadsheet and a fast way to get an app pulled from the Play Store, or worse, to genuinely deserve it.

What's next

Phase 2 is launch readiness: the Play Store listing, the legal review this site's Privacy Policy and Terms keep flagging as drafts, and production ad configuration. Phase 3, after that, is where the Ambassador program above starts to matter at scale.

Is TAVEXA MINI a scam?

The question everyone asks before they've read anything else on this site — and a fair one, in a genre with a real scam problem. Here's the honest, specific answer, not a denial.

TM TAVEXA MINI Team October 20265 min read

Asking this is the right instinct, not an insult. "Mine crypto on your phone" and "invite friends to earn more" are two of the most reused sentences in mobile-app history, and most of the time they're attached to something that quietly disappears once it has enough installs. We'd rather answer the question directly than pretend it's rude to ask.

The usual red flags, checked against what this app actually does
What a scam usually does	What TAVEXA MINI does instead
Pays you (or your referrer) real money for signing up	Zero payout for an invite landing. A referral only ever adds a capped mining-rate bonus once the friend reaches Level 3 and is actually mining — see the rate math below.
Promises a coin that will "be worth something" once it launches	No tradable token exists today, and nothing here promises one. TVX is the in-app unit you mine and has no monetary value.
Credits ad rewards on the client's word alone	A reward is credited only after AdMob's own server-side verification confirms the impression to our backend — the app client can't just claim you watched something.
Multi-level referral commissions — you earn off a downline you never met	One level only. You earn from the friends you invited directly; nothing from who they invite.
No way to delete your account or data	Built end-to-end, in-app and by email, and a documented page for exactly how.
An anonymous team with no accountable process	A public, numbered whitepaper, a published economy config version, and a dev blog that names real bugs we found in our own backend — including this one.

A denial costs nothing to write. A table that links to the receipts costs a lot more, which is the point.

What we are not

Not a cryptocurrency. Not an investment. Not a security. There is no exchange listing, no floating price, and nobody here will ever message you first asking for a wallet seed phrase, a password, or a "verification fee" — our own group rules say so explicitly, because that specific scam targets communities exactly like ours. TVX is an in-app reward for time and attention, nothing else, today.

What we actually are

An idle mining game: start a session, it earns while your phone is closed, come back and claim it. Watch an optional ad for more. Build a streak. That loop is real, it's server-authoritative (the client can't forge what it's worth — see how the two engines stay in sync), and it pays out in TVX you can spend inside the app today. Whether that's worth your time is a judgment call we can't make for you — we can only make sure every number behind it is true.

The honest limitation

There's no cash-out today. If you're installing this specifically to make money, don't — that feature doesn't exist, and we'd rather lose that install than imply otherwise. TAVEXA MINI is an idle mining game; TVX is its score.

Phase 2, so far: what shipped since launch readiness began

Phase 2 was supposed to be the quiet one — store listings and legal review. It didn't stay quiet.

TM TAVEXA MINI Team October 20264 min read

Phase 2's job, on paper, was launch logistics: a store listing, a legal review, production ad configuration. It still is — but three things grew out of it that were big enough to ship on their own, plus a closed-testing milestone that makes all of it real for the first time.

1

Competition

Weekly leagues, eight tiers deep

Bronze through Legend, ranked cohorts of up to 30, promotion and demotion every Monday. From Silver up, promotion also needs active teammates — not just TVX — so a lone high scorer can't camp a slot a real team earned.

2

Telegram

Reminders that stay out of the group

A streak-loss alert, a come-back nudge, a referral-activity nudge and a league-promotion nudge — every one a private DM, opt-in via /notify on, never posted where anyone else can see it.

3

Hardening

Account security, tightened

Deleting your account and changing your email or password now all re-verify your current password first — a valid session alone isn't enough for any of the three. A password change also signs you out everywhere else.

4

Milestone

Closed testing, live

The app is now in a real Google Play closed test — the required step before anyone outside it can install from the store. Everything above shipped before we asked a single outside tester to open it.

Phases shipped, one in progress

A launch-readiness phase that only ships paperwork isn't using the waiting room for anything.

What's still actually open

The Play Store listing itself, the data-safety form, and the content-rating questionnaire — all genuinely in progress, not done. Production AdMob review is pending on Google's side, outside our control, which is exactly why closed testing starts now instead of waiting on it.

TAVEXA MINI is live on Google Play

Phase 2 is done. Here is what fourteen days of closed testing changed before the public build went out.

TM TAVEXA MINI Team October 20264 min read

On 7 October the app went into a Google Play closed test. Every day after that, between thirteen and seventeen testers had it installed, and they used almost everything: daily check-ins, mining sessions, rewarded ads, tasks, the mystery box, weekly leagues and invites. Fourteen days later Google granted production access, and the first public build — version 1.0.0 — is now on Google Play.

1

Ads

Ad rewards that settle on their own

Testers saw ad rewards stuck on “pending”. The server was rejecting Google’s verification callbacks because of a format mismatch in the ad-unit check. Fixed on the server, so it reached every installed copy at once, no update needed.

2

Invites

Invite codes on Google sign-up

A code typed into the invite field was ignored if you then chose “Continue with Google”. It is now applied on both sign-up paths, and the code from an invite link still carries through the Play Store install.

3

Stability

Fewer background errors

The app’s own error reports pointed at a few screens that tried to load data after you had already left them. Harmless to your balance, but noisy — all of them are guarded now.

4

Security

Tighter database permissions

A routine security scan found two internal database functions that were reachable more widely than intended. Both were locked down to the server only, and the data showed no sign either had been misused.

A closed test is only worth the wait if the build that comes out of it is different from the one that went in.

What hasn’t changed

TVX is still an in-app rewards balance — not a cryptocurrency and not a promise of future value. Ads are still optional. Every reward is still computed and verified on the server, and every rule is still in the whitepaper.

What’s next

Phase 3 is growth: ambassadors onboarded through the in-app program, a regular cadence of limited-time events and a small-group team layer. If you play, the fastest way to shape it is the Telegram community.

Version 1.0.3: crews, eras and 105 badges

The biggest update since launch. Mining gets social, early players get rewarded for being early, and badges finally pay.

TM TAVEXA MINI Team November 20265 min read

Until now TAVEXA MINI was mostly a game you played alone, next to other people. Version 1.0.3 changes that. You can mine as a crew, open anyone’s profile from the leaderboard, and earn your place in the game’s history just by being here early. Here is everything that shipped.

1

Social

Crews

Start a crew of up to five, or join one with a code. On any day three or more of you claim a mining session, everyone who mined gets a bonus: +30 each at three, +40 at four and +100 when the whole crew mines. Members count from Level 3, and a reminder goes out when your crew has mined and you haven’t.

2

Growth

Eras and the Vanguard

We’re in the Genesis Era: every mining session runs +100% until the community reaches 2,500 miners. Then Dawn (+75%), Rise (+50%) and on down as we grow. The first 250 miners to reach Level 5 are the Vanguard — a numbered badge and +5% mining, kept for good.

3

Progression

105 badges that pay

Eighteen badge families with five tiers each, from Bronze to Diamond, plus specials and a few hidden ones. Every family tier pays TVX the first time you reach it: 50, 150, 500, 1,500, then 5,000. Your badge score earns you a title, from Prospector to Legend of the Deep.

4

Profiles

Tap any name

Names on the leaderboard, in your league and in chat now open that player’s profile: level, pinned badges, best streak and pickaxe. Game stats only — never an email or a balance. Share your own as an image card.

5

Community

Ambassadors, partners and promo codes

Active ambassadors and partners mine +5% faster and wear their role on their profile; partners get a named invite link. Promo codes from our channels can be entered on the Rewards tab. Bring friends to Level 3 and you unlock pickaxe skins and a title at 5, 25 and 100.

6

Fairness

Gifts can’t buy a league win

Better pickaxes now unlock by level: Iron at 3, Gold at 8, Diamond at 16, Obsidian at 20. Level only comes from TVX earned by playing, and promo or program TVX doesn’t count toward Level or the leaderboard — so the race stays about who actually mines.

105

Badges

+100%

Genesis Era bonus

250

Players per crew

A mining game is more fun when someone notices you didn’t show up today.

What hasn’t changed

TVX is still an in-game score with no cash value. Ads are still optional. Every reward is still computed on the server, and every number is in the field guide.

Privacy Policy

Last updated 5 November 2026

This policy explains what personal data the TAVEXA MINI app (“the App”, “we”) processes, why, and what choices you have. It covers the mobile app and this site.

Who is responsible

The controller is the operator of TAVEXA MINI. Contact for privacy requests: feedback@tavexa.app.

Data we process

What we process, and why
Category	What	Why
Account	E-mail address, username, password (stored only as a salted hash by our authentication provider), sign-in method (e-mail, Google or Telegram). If you open TAVEXA MINI inside Telegram (the Telegram Mini App), the Telegram user id, username and first name that Telegram passes to the Mini App (never your phone number)	Create and secure your account
Gameplay	TVX balance, ledger of rewards, level, streaks, mining sessions, in-app store purchases, referral relations, partner-task submissions (the username or link you submit)	Run the rewards economy, prevent fraud
Device & notifications	Push token, platform, app version, time-zone offset, notification preferences	Deliver the reminders and announcements you enabled
Fair-play checks	About once a day the Android app asks Google Play Integrity whether it is a genuine copy on a genuine device; we store that verdict with a random install identifier (not a hardware id)	Prevent fraud such as modified apps, emulators and multiple accounts. Nothing is taken automatically; a flagged account is reviewed by a person and you can contact us
Network	IP address — used briefly for abuse throttling and not stored in your profile	Security and anti-abuse
Advertising	Google AdMob may process your advertising ID and ad interactions, subject to your consent choices (consent form and privacy options in Settings)	Show rewarded ads and verify rewards
Diagnostics & usage	A pseudonymous in-app event log (screens, claims) and crash or error reports linked to your account id	Fix bugs, improve the App
Community	Chat messages (kept about 48 hours), reports you file, users you block; your Telegram account id if you choose to link it, and Telegram reminders only if you turn them on with /notify on in the bot	Operate chat and community tasks, moderation
Public profile & crews	Other players can see your username, join date, level, badges, equipped pickaxe and frame, any program role, and, if you join a crew, your crew name, crew members and whether you mined today. Your e-mail and TVX balance are never shown	Leaderboards, profiles and crews
Applications	Details you submit in the Ambassador / Partner form	Review your application
Launch waitlist (closed)	E-mail address (and the invite code, if you arrived through an invite link), only if you asked before launch to be notified. The waitlist closed when the app went live on Google Play; new addresses are no longer collected	Send you one e-mail when the app went live

We do not collect precise location, contacts, photos or microphone data.

Legal bases

Contract (providing the App you signed up for), legitimate interests (security, fraud prevention, diagnostics), and consent (personalised advertising, push notifications, optional Telegram linking or Telegram Mini App sign-in). You can withdraw consent at any time in Settings or your device settings.

Retention

Account and gameplay data are kept while your account exists. Chat messages are deleted automatically after roughly 48 hours. Diagnostics, event logs, crash reports and fair-play check results are kept for up to 90 days; crash reports held by Firebase Crashlytics expire on their own within 90 days, also after you delete your account. When you delete your account, all personal data listed above is deleted, except records we must keep by law.

Your rights

You may request access, correction, export, restriction, objection or deletion of your data, and lodge a complaint with your data-protection authority. In the app: Settings → Account → Delete account; in the Telegram Mini App: Wallet → Delete my account. Or see how to request deletion. Otherwise email feedback@tavexa.app.

Children

The App is not directed to children and you must be at least 16 years old. We do not knowingly process data of younger users; if you believe a child has registered, contact us and we will delete the account.

Security & transfers

Data is encrypted in transit and access to production data is restricted. Some processors may process data outside your country under appropriate safeguards, such as standard contractual clauses.

Changes

We may update this policy. Material changes are posted here and announced in the App.

Legal

Terms of Use

By creating an account or using TAVEXA MINI you agree to these terms and to our Privacy Policy. If you don’t agree, don’t use the app.

Acceptance

You must be at least 16 years old, and 18+ for the ambassador or partnership program.

What TVX is

TVX (formerly called “Points”) is a virtual, in-app unit used for progression, the in-app store and leaderboards. TVX has no cash value and is not money, securities or crypto-assets. Cash-out or gift-card redemption is not available unless and until we announce it in the App. Any future redemption will be subject to separate conditions, availability, verification and limits, and TVX may be adjusted or expire as described in the App.

Fair use

One account per person. You must not use bots, emulators, automation, multiple accounts, self-referrals, VPN or IP tricks, modified apps, or exploit bugs to earn TVX, and you must not manipulate ads or task verification. We may withhold, reverse or reset TVX and suspend or delete accounts that break these rules, without prior notice where necessary to protect the service.

Ads and rewards

Rewarded ads are optional. Rewards are credited after server-side verification and may be limited by daily caps, cooldowns and eligibility. Availability and amounts can change.

Partner & social tasks

Some tasks ask you to follow or join third-party services and submit proof. Submissions are reviewed manually; false or duplicated submissions are rejected. Rewards are paid only after approval. Follow the rules of the third-party platform.

Community and chat

Do not post illegal, hateful, harassing, sexual, scam or spam content, personal data of others, or links to unsafe sites. Messages may be removed and repeat offenders muted or banned. You can report and block other users.

Your content and licence

You keep ownership of content you submit but grant us a limited licence to host and display it to operate the service.

Availability and changes

The App is provided “as is”. We may change, pause or discontinue features, the economy and rewards, or require an app update, to keep the service safe and sustainable.

Termination and deletion

You can delete your account at any time in Settings → Account (or see how to request deletion). We may suspend or terminate accounts that violate these terms.

Liability

To the extent permitted by law we are not liable for indirect or consequential loss, loss of TVX, or interruptions outside our reasonable control. Nothing limits liability that cannot be limited by law.

Governing law & contact

These terms are governed by the laws of the operator’s country of establishment. Contact: feedback@tavexa.app.
