Terms & Conditions

Last updated: 26 August 2026 · Regulamin for the Whaaack! Android app, the Amazfit watch edition, and this website.
What changed on 26 August 2026: a second Whaaack! now runs on Amazfit watches under Zepp OS, sharing this account and this backend with the Android game. What it does not contain, where you sign in to it, and which board its runs go on are set out at the end of section 2.
What changed on 16 August 2026: Google Play Games was added — achievements, profile statistics, and a third way to hold an account. See sections 2 and 3.

1. Who you are contracting with

IDCT Bartosz Pacholek, Kaszubska 12/8C, 70-403 Szczecin, Poland, NIP PL7642542255 (“we”, “us”). Contact: the contact form.

These terms govern your use of the Whaaack! Android application, the Whaaack! watch edition for Amazfit watches running Zepp OS, and this website. By installing or using either application you accept them. If you do not accept them, do not use either. Where a section names one edition, it applies to that one only.

2. What the service is

Whaaack! is a single-player arcade game. It is free to download and free to play in full, in both editions. Two things are genuinely optional:

• an account, which is required only to place scores on a public leaderboard — and which, in the Android app, you can create from Play Games instead of an email address, see section 3; and
• a one-time ad-free purchase, which removes advertising from the Android app.

Neither is required to play, and nothing about the gameplay is locked behind either.

Google Play Games is a third thing, and it is not opt-in. If your device already has a Play Games profile, the app connects to it when it starts — before you have tapped anything — and from then on it unlocks achievements and reports your runs to Google, casual runs included, whether or not you have a Whaaack! account. That is how Play Games version 2 is built: there is no in-app switch, because none of it is ours to hold. Turning it off means signing out of Play Games, in the Play Games app or your Google account settings, after which the app sends nothing and the game plays exactly as before. Exactly what is sent is set out in the privacy policy. All of that is the Android app: the watch edition contains no Play Games code, so none of it happens there.

The Amazfit watch edition

There is a second Whaaack! that runs on Amazfit watches under Zepp OS. It is the same game laid out for a small round screen, on the same account and the same backend, so these terms cover it too. What differs:

• Nothing in it is for sale, and the game carries no advertising. It is free in full: there is no ad-free unlock, because there are no ads to remove. Its settings page inside the Zepp app links out to three places — a buy me a coffee page, our Android game on Google Play, and our own site — and a tip left through the first unlocks nothing and is handled by Buy Me a Coffee, not by us.
• You sign in from your phone, not on your wrist. The watch has no keyboard, and the app on it holds no network permission of its own — it asks the watch for the screen size and for local storage, and for nothing else — so creating an account, signing in and out, changing the password and asking for a reset are all done on the Whaaack! settings page inside the Zepp app, under Zepp → Profile → your device → Whaaack! → Settings, and a companion service in that same app makes every network call for the watch. Only an email address and a password work there — see section 3.
• Watch runs are ranked on a board of their own. They are not mixed with phone scores, because a three-by-three grid tapped with one finger does not produce times comparable to a four-by-four tapped with two thumbs. The account and the display name are shared: one account, one name, two boards — so playing both editions is not keeping two accounts, and section 4 applies to each board on its own.

The watch edition reaches your watch through the Zepp app rather than through Google Play. Zepp Health is not a party to these terms: it sells nothing here and takes no payment for the game. The game, and anything wrong with it, remains ours.

3. Your account

There are three ways to have one in the Android app, and they differ in what you give us:

• Email and password — you must give an address you control, confirm it, and keep the password to yourself.
• Google — Google confirms who you are and we receive your address and name. There is no separate password.
• Play Games — your Google Play Games profile identifies the account. It has no mailbox and no password: internally it is keyed to an address derived from your Play Games player ID, at a domain that cannot receive mail, so there is nothing to send a reset to. Signing in with Play Games again is the only way in — on any Android device carrying your Play Games profile, which is also what makes it portable. Your Play Games gamer tag becomes your starting display name on the public leaderboard, and you can change it afterwards like anyone else. Signing out of Play Games therefore locks you out of this account, since the profile is the only credential; signing back in restores it. Be aware of the limit that follows: this kind of account cannot be given an email address or a password later, and cannot be recovered by us if you lose the Google account behind it. If that happens the account and its scores remain on the leaderboard and we may have no way to establish that they are yours. If that risk matters to you, use an email or Google account instead — both can be recovered.

Only the first of the three reaches the watch. The Zepp settings page signs in with an email address and a password and offers nothing else, so an account held through Google or Play Games — neither has a password of its own — does not sign in there; to be ranked on the watch you would sign up on the Zepp page with an address that has no account on it yet, and that is a second, separate account. Otherwise it is one account throughout: the same profile, the same name, the same password, so a password changed from the Zepp app is the one the Android app then wants. Confirmation and reset links sent from the watch edition open a page on this website, where a new password is typed, so an account can be created, confirmed and recovered by somebody who has never installed the Android game.

Whichever you use:

• One person, one account. Do not create accounts to inflate or manipulate the board. Note that an email or Google account and a Play Games account are separate accounts even when they are the same person — we have no way to know they are you both times, and we do not merge them. The Android app and the watch edition are the opposite case: one account serves both, so playing on both is not keeping two. Keeping two of your own is not cheating; using several to occupy the board is, and falls under section 4.
• Your display name is public. It must be 2 to 24 characters long, made only of unaccented letters a–z, digits, spaces, dots, underscores and hyphens, and it must start and end with a letter or a digit. It must also be unique, ignoring capitalisation. Where the name is not one you typed — a Play Games gamer tag, or the name on a Google account — we fit it to those rules automatically: characters they do not allow are dropped, anything longer than 24 is cut, a number is added if the name is already taken, and if too little usable text survives we assign a neutral generated name instead. So the name on the board may differ from your gamer tag, and you are free to change it. Beyond that it must not be offensive, impersonate anyone, contain contact details or advertising, or infringe anyone's rights. We may replace a name that breaks the last rule with a neutral one — every account has to have a name, so there is nothing to delete — and we will tell you why. To report someone else's name, use the contact form.
• You may change your display name once every 30 days. The first change is always available — the clock starts at your first rename, not at sign-up — which matters if the name you were given was derived rather than chosen. The control for it is in the Android app: the watch edition asks for a name when you sign up but cannot change one afterwards, so if you signed up from the Zepp app and have no Android install, ask us through the contact form.
• If you are under 16, do not create an account without a parent or guardian's agreement. Casual play requires no account.
• You can delete your account at any time — see section 10.

4. Fair play

Ranked scores are meant to be earned. You agree not to modify the app, tamper with its traffic, automate play, or submit scores that were not produced by actually playing. We run every submitted run through server-side checks and rate limits, and one the game could not have produced — or one of a flood from a single account — is refused as it arrives; the app tells you the run was not recorded. We can also delete a score after the event, and in serious or repeated cases suspend the account. Where we do that we will say so if you ask.

This holds in both editions, each against its own board: watch runs are checked and rate-limited against limits written for the watch's smaller grid, and one those limits reject is refused as it arrives in the same way. On a watch the submission is made by the companion service inside the Zepp app on your phone, so that link is part of the traffic you agree not to tamper with.

5. Advertising

Unless you have bought the ad-free unlock, the Android app shows advertising supplied by Google AdMob between runs. Where Google's consent framework requires it — the EEA, the UK and the other regions it covers — its consent form is shown before any ad is requested, and Settings → Ad privacy options then lets you change that choice at any time. Details are in the privacy policy.

The watch game shows no advertising and contains no advertising code, so there is no consent form there and no Ad privacy options row — there is nothing to ask you about. The links out of its settings page are listed in section 2.

6. The ad-free purchase

This section is about the Android app. The watch edition is free in full — no purchase, no unlock, nothing sold through the Zepp app — so buying the unlock changes nothing on the wrist, because there are no ads there to remove.

How it is sold

The ad-free unlock is a one-time purchase, not a subscription. It is sold through Google Play's billing system. For users in the European Economic Area and the United Kingdom, Google is the seller of record: the payment contract for the transaction is with Google, Google issues the receipt, and Google's refund policy applies to it. We remain responsible for the content and the functioning of what you bought.

What you get

Advertising is removed from the app for as long as Google Play reports the purchase as yours: there is no expiry and nothing to renew, and the only thing that ends it is the purchase itself being refunded and revoked. The entitlement is tied to the Google Play account that bought it, so it follows you to a new device and survives a reinstall. Use Settings → Restore purchases if it does not appear immediately.

We deliberately err on your side. Once an install has confirmed the purchase with Google Play, that install keeps the ads off whenever Play cannot be reached afterwards — offline, on a plane, in a tunnel — for as long as that lasts, with no time limit. The one exception is a fresh install that has never managed to ask: it has nothing to go on, so it shows ads until it reaches Play once. Access is only ever withdrawn after Google confirms, in more than one session, that the purchase is no longer held.

Right of withdrawal (prawo odstąpienia od umowy)

Digital content supplied other than on a tangible medium is normally subject to the 14-day right of withdrawal under the Polish ustawa o prawach konsumenta. That right is lost under art. 38 ust. 1 pkt 13 of that Act only if all of the following happened: performance began with your express and prior consent, you acknowledged before performance began that you would thereby lose the right, and we gave you confirmation of that on a durable medium.

If something is wrong with it

Chapter 5b of the ustawa o prawach konsumenta (art. 43h–43q) governs contracts for digital content. If the ad-free unlock does not conform to the contract — for example, ads keep appearing — you may require us to bring it into conformity, and if we fail to do so within a reasonable time and without significant inconvenience to you, you may demand a price reduction or withdraw from the contract. Tell us through the contact form and we will deal with it; we will confirm receipt and tell you what we intend to do.

This part applies to the watch edition too, and we do not rely on its being free to escape it: you give us an email address, a password and a display name in order to place a score there, which is what that chapter covers. There is no price to reduce or refund, so the remedy is that we fix it — and if we cannot, you can stop and delete the account under section 10, at no cost.

7. Intellectual property

The Whaaack! name, the artwork, the audio and both applications — the Android app and the watch edition — are protected. You get a personal, non-exclusive, non-transferable, revocable licence to use them on devices you control, a paired watch included, for your own non-commercial enjoyment. You may not redistribute, resell, decompile (beyond what law permits), or use the assets in your own products without written permission.

By placing a run on the leaderboard you allow us to publish your display name and that score on the leaderboards in either edition, the separate watch board included, for as long as you keep the account. This covers a display name you never typed — one derived from a Play Games gamer tag or a Google account name — which is published on the same terms, and which you can change in the Android app's Settings if you would rather appear under something else.

8. Availability, and changes

The game is provided as it is. We do not promise it will be uninterrupted or error-free, and the leaderboard depends on third-party infrastructure that can be unavailable. Casual play keeps working offline regardless.

On a watch there is one more link in that chain. The watch app makes no network calls of its own, so signing in, opening the board and recording a run all need your phone within reach and the Zepp app running; without it the game still plays and still keeps your best time on the watch, and a run finished out of range is not recorded — it is not held and sent later.

We may update either application, change or discontinue features, or reset a leaderboard where it has been compromised. The two are separate programs and can be updated, changed or withdrawn independently of each other. If we discontinue the service entirely we will give reasonable notice and, where the law requires it, a proportionate refund of anything paid for.

9. Liability

Nothing in these terms excludes or limits liability that cannot be excluded or limited by law — including for death or personal injury caused by negligence, for intentional fault, or under mandatory consumer-protection rules. Subject to that, our liability for the free parts of the service is limited to what the law requires, and in relation to the paid unlock is limited to the amount you paid for it.

10. Ending it

You can stop at any time by uninstalling the app; on a watch that means removing Whaaack! from the watch through the Zepp app, which takes with it the one thing the watch itself keeps, your best time. To remove your data as well, use Settings → Delete my account in the Android app, or the deletion page, which explains how to do it with neither application installed. Deletion is immediate and irreversible, and covers your display name, every score we hold — watch runs included, in the same operation and by the same cascade — and whatever identifies the account: your email address, or the Play Games player ID where that is what you signed in with.

The watch edition has no Delete my account control of its own: it can create an account and sign in to one, but it cannot erase one. Signing out happens on the Whaaack! settings page inside the Zepp app, where your session is kept, and it is separate from signing out of the Android app: do both if you want both. After a deletion that page may go on saying you are signed in until it next tries to reach us.

Deletion does not reach your Play Games profile. Achievements and run statistics belong to Google, not to us, and survive the deletion; clear them through the Play Games app or your Google account. Nor does it sign you out of Play Games — sign in that way again and you get a new, empty account, because the player ID was the only thing tying you to the old one.

Deleting your account does not cancel the ad-free purchase, which belongs to your Google Play account and remains available to you.

We may suspend or terminate an account that seriously or repeatedly breaches section 3 or section 4. Where we do, we will tell you why and you can dispute it through the contact form.

11. Complaints and disputes

Please come to us first, through the contact form. We aim to respond within 14 days.

If we cannot resolve it, a consumer in Poland may seek help from the powiatowy (miejski) rzecznik konsumentów, from a regional Wojewódzki Inspektorat Inspekcji Handlowej, or from the UOKiK, and may use out-of-court dispute resolution.

The European Commission's online ODR platform is no longer an option: it was shut down on 20 July 2025 and Regulation (EU) 524/2013 was repealed. Some templates still link to it; it does not work.

Complaints about a payment, including refunds, are handled by Google Play as seller of record.

12. Governing law

Polish law applies. If you are a consumer habitually resident elsewhere in the EEA, this choice does not deprive you of the protection of the mandatory rules of your own country (Article 6 of the Rome I Regulation), and you may bring proceedings in the courts of your place of residence.

13. Final provisions

If any provision is found unenforceable, the rest stands. We may amend these terms — for example when features change or the law does — and will post the new version here with a fresh date; material changes affecting the paid unlock will be notified in the Android app, which is the only edition that has one. If you play only on the watch, this page is where changes appear.

These terms are published in English. Where a Polish-language version is provided and the two conflict, the Polish version prevails for consumers resident in Poland.
