1. What data we collect

None. This version has no account of its own and asks you to create nothing. It does not ask for your name, email address, phone number, date of birth, location, contacts, photos, files, microphone or camera. It contains no analytics, crash-reporting or advertising SDK, and it does not read the Android advertising ID.

We run no servers of our own, so we receive nothing about you. Everything the game saves is listed in section 3. Section 2 says exactly what goes to Google if you sign in to Google Play Games.

2. Google Play Games (optional)

The app offers leaderboards and achievements through Google Play Games Services. This is optional: Google may offer to sign you in with your Google account, and there is one row on the Statistics page that asks. You can decline, or leave it alone. Nothing in the game is locked behind an account: every world and every medal is earned by playing, and they all show on your phone whether you sign in or not.

If you sign in, the app sends to Google, under your Play Games profile: the score of each finished game (Classic and Jars have a board each, the Daily tray has its own, and the Journey has a board for the stars you have won), and which medals you have earned: there are twenty-three of them, on the game’s six ladders. A practice run of a past Daily tray is not sent. Google shows these on the leaderboards and on your achievements page. Your leaderboard entry, your Play Games name and avatar and your score, is visible to other players according to your own Play Games profile settings (Google’s “Make your gamer profile public” toggle). To attach any of this to your profile, Google Play services on your phone sends your Play Games player ID, an ID Google creates for this game and not your email address. The app shows your Play Games display name on the device; this version does not send your name or your email anywhere.

This data is held by Google, not by us, and Google’s Privacy Policy applies to it. You can sign out, change your profile visibility, or delete this game’s Play Games data in the Google Play Games app or at myaccount.google.com. We can see the leaderboards and the achievement totals in the Play Console, but no email address and no account details.

Cloud save (optional). While you are signed in to Play Games, the app also keeps one small backup in your own Google Drive app data, Google’s “Saved Games” feature. To do that the app asks for one Google permission, drive.appdata: the app-data folder of your Drive, a private space only this app can see. It does not read, open or list any other file in your Drive.

The backup holds your best scores, your lifetime totals, the worlds you have earned, the Journey levels you have won with the stars and best score each gave you, your Daily tray results, your last 30 finished games, and your settings, sound, vibration, skin, marble look, language and the rest, so that a new phone opens the way the old one did. It holds no name, no email address and no device id. The game you are part way through, and the moves of your best wins, are deliberately left out: they stay on the phone they were played on. The backup is read by you and the game, and it does not reach us. Deleting this game’s data in the Play Games app or in your Google account settings deletes the backup too.

The cloud save runs only while you are signed in to Play Games, and Google can refuse it. It is a convenience, not a guarantee. Please do not treat it as your only copy of anything.

3. Data stored on your device

This version saves the following on your phone, in the app’s own private storage:

• the game you are playing in each mode, and your best score for each mode and difficulty;
• the difficulty you chose, the mode you played last, and whether you have seen the taught first game and each of the nine one-off tips and first-time moments;
• your Journey: for each level you have won, how many stars it gave you, how many moves you had left, your best score on it, and whether you won it without a tool; the moves of your best win of a level, so you can watch it again; and the level you are part way through;
• your Daily tray: the day’s game while you are playing it, and your results, streak and medals;
• your last 30 finished games and your lifetime totals;
• your settings: sound, vibration, skin, marble look, the marks on the marbles, show a move, larger next marbles, less motion and language;
• the worlds you have earned, and which ones you have already seen;
• if you sign in to Google Play Games: the scores and medals still waiting to be sent, which ones Google already has, and when the cloud save last ran or was refused;
• whether the app has already asked you to rate it, so it asks only once, and the colour its opening screen should be.

None of it is sent to us. Uninstalling the app deletes all of it from the phone. If you sign in to Google Play Games, some of it goes to Google as well: section 2 lists exactly what.

Android backup. Android can back up apps’ data to your Google account and put it back on a new phone. If you have turned backup on, Android may include the list above in your phone’s backup, together with your other apps’ data. That is Android’s own feature, run by Google under your Google account and Google’s Privacy Policy. The app sends nothing itself, and we do not see the backup. You can turn backup off in your phone’s settings.

4. Third-party services

This version contains no advertising network, no analytics service and no crash-reporting service. Only Google services are in it, all run by Google LLC through Google Play on your phone:

• Google Play Games Services (Google LLC): the leaderboards, the achievements and the cloud save. It sends nothing until you are signed in, and you do not have to sign in. Section 2 says what it sends; Google’s Privacy Policy covers what Google then does with it.
• Google Play In-App Updates (Google LLC). When you tap “Check” beside the version number in Settings, the app asks Google Play whether a newer version is out. Nothing about you is sent: Google Play is asked about the app, not about you.
• Google Play In-App Review (Google LLC). Once, after you win a Journey level with three stars or finish a chapter, the app asks Google Play to show its rating card. Google decides whether it shows. If you rate the game, your rating goes to Google Play under your Google account, like any Play Store review, and Google’s Privacy Policy applies. The app gets nothing back: not whether you rated, and not what you said.
• Android backup (Google LLC), only if you have turned it on: section 3 says what it may copy.

Three buttons in the app hand something to another app on your phone, at your request, and none sends anything to us by itself: “Privacy policy” in Settings opens this page in your browser, “Update” beside the version number opens the Play Store when a newer version is out, and “Share” opens the app you choose (section 9). Those apps have their own privacy policies.

5. How your data is kept safe

• On your phone. Everything in section 3 is written to the app’s private storage, which Android keeps separate from other apps. No other app can read it.
• This version opens no connection of its own. It holds no internet permission. When you sign in to Play Games, the sending is done by Google Play services, a separate part of your phone, over Google’s own encrypted connection. This version does not talk to a network by itself, and we run no server.
• The cloud save is yours. It sits in your own Google Drive app data, a private folder only this app can reach, and it is protected by your Google account. We have no way to read it.
• On our side, nothing. We run no servers, no database and no account system, so there is no store of player data anywhere that could be lost or breached. Signing in to Play Games does not change that: the data goes to Google, not to us.
• No password to lose. This version has no login of its own. Play Games sign-in is Google’s, handled by your phone, and the app does not see a password.
• A backup is yours. If Android backup is on, the copy is kept by Google under your Google account, protected by it. We have no way to read it.

6. How long data is kept

• On your phone: until you delete it (section 7). The app keeps your most recent 30 finished games and up to 2,000 days of Daily results, and drops the oldest beyond that by itself.
• In your Google account, if you signed in: until you delete this game’s Play Games data. Your scores, your medals and the cloud save stay there until then; section 7 says how to remove them.
• In your Google account, if Android backup is on: as long as Google keeps your phone’s backup, under Google’s own rules, or until you delete it.
• By us: nothing. We have no servers and hold no copy of any of it.

7. Deleting your data

You control everything the app stores, and you can remove all of it yourself, in one step:

• Uninstall the app, or
• open Android Settings → Apps → Tiltrow → Storage and tap “Clear storage”.

Either one deletes your games, scores, Daily results and settings from the phone.

A copy in Android backup: if you use Android backup, open your Google account’s backups, in Google Drive, under Storage → Backups (drive.google.com/drive/backups), and delete your phone’s backup, or turn backup off in your phone’s settings. This removes the backup of your whole phone, not only this game.

If you signed in to Google Play Games, your scores, your medals and the cloud save are in your Google account, not on the phone, so clearing the app does not remove them. To delete those:

• open the Google Play Games app → your profile → Settings → Delete Play Games account & data, where you can delete the data for this one game, or
• go to myaccount.google.com and remove it there.

That removes the leaderboard entries, the achievements and the cloud save together. We hold no copy on our own servers, because we run none, so there is nothing for us to delete on our side. If you have a question about deletion, write to hello@byteonyx.com and we will answer within 30 days.

8. Selling and sharing

We do not sell your data. We do not share it with any third party for that party’s own purposes: not with advertisers, not with data brokers, not with anyone. We do not use your data for advertising, profiling or any automated decision-making.

In this version there is nothing to sell or share: the data does not reach us.

9. Sharing a score

When you tap “Share” after a Daily tray, the app opens your phone’s share sheet with a short text and a picture it draws on your phone: the day’s number, your score and your streak. The picture does not show the board, so it cannot spoil the day for anyone else. It is made on the device and handed straight to the app you pick; it is not uploaded anywhere first. You choose which app receives it. We do not receive or see it.

10. Permissions

This version requests no Android permissions that need your approval: no location, no camera, no microphone, no contacts, no storage access, no notifications. It holds no internet permission either.

Signing in to Play Games does not change that. Google Play services is already on your phone as part of Android, and the sending is its work, not the app’s. That is also why no permission dialog appears.

11. Internet

The game plays offline, in every mode and on the Daily tray, and it does not wait for a network to let you play. This version opens no connection itself: it has no internet permission.

Only other parts of your phone reach the internet, through Google Play services or other apps rather than through the game:

• Play Games, once you have signed in: Google Play services sends your scores, your medals and the cloud save (section 2). Offline, the game simply keeps your scores and medals and sends them the next time it can.
• “Check” beside the version number in Settings, when you tap it: Google Play is asked whether a newer version is out (section 4).
• Google Play’s rating card, when it shows and you rate; Android backup, if you have turned it on; your browser, if you open this policy; and the app you pick when you share.

The things that open other apps are described in section 4.

12. Advertising

This version contains no ads, no in-app purchases, and no advertising or marketing SDK of any kind. It does not read or transmit the Android advertising ID, and it takes no part in any ad network or cross-app tracking. Nothing in this version can be bought; the skins are earned by playing.

13. Children

The app is a general-audience game. It is not directed at children and is not part of Google Play’s Designed for Families programme. This version has no chat and no ads. It collects no personal data from anyone, so it collects none from children either.

We do not knowingly collect personal information from a child under 13 (or the equivalent minimum age in your country). If you believe a child has provided us with personal data, write to hello@byteonyx.com and we will act on it.

14. Your rights

Depending on where you live, for example under the GDPR in the EEA and the UK, or the CCPA/CPRA in California, you have rights to access, correct, export, delete and restrict the use of your personal data, and to object to it being sold or shared.

We hold no personal data about you, so there is nothing for us to hand over, correct or delete on our side, and nothing is sold or shared. In practice you exercise these rights directly: section 7 deletes everything on the device, and everything in your Google account if you signed in. If you would like this confirmed in writing, or you have any other request, write to hello@byteonyx.com and we will answer within 30 days, free of charge.

15. Changes to this policy

If the app changes in a way that affects this policy, we will update this page and the effective date at the top of it before that version ships. This page keeps the same address, so a link from the app or from the store listing always reaches the current version. Please check it from time to time.
