Privacy Policy
The short version. The app collects no data. It has no ads, no analytics and no crash reporting, and it asks for no Android permissions at all. Everything it remembers stays on your phone — unless you choose to sign in to Google Play Games, and then your scores, your achievements and one small backup go to Google under your own Play Games profile. Signing in is optional; the game plays exactly the same without it.
Tiltrow: Marble Puzzle (“Tiltrow”, “the app”) is a free game for Android, published by ByteOnyx, the one-person studio of Md. Yousuf Ali (“we”, “us”). This page explains what the app does with data.
Summary
The whole policy in one table. Every row is explained below.
| Data | Collected by us | Sent anywhere | Why |
|---|---|---|---|
| Name, email, phone, address | No | No | The app never asks for them |
| Location | No | No | Not used |
| Contacts, photos, files, microphone, camera | No | No | Not used |
| Advertising ID | No | No | There are no ads |

| Games, scores, levels won, Daily results, settings | No | No | Kept on your phone so the game works |
| Your scores and achievements | No | Only if you sign in to Google Play Games | Leaderboards and achievements |
| A backup of your progress | No | Only if you sign in — to your own Google Drive app data | So it comes back on a new phone |
| A score you choose to share | No | Only to the app you pick | You asked to share it |
1. What data we collect
None. The app 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, ever. Everything the game remembers is listed in section 3, and it stays on your phone unless you sign in to Google Play Games — section 2 says exactly what goes to Google if you do.
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 never tap it, and the game plays exactly the same. 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 never 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; it never sends 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 cannot 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. Only you and the game can read the backup; we cannot. 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
The app saves the following on your device only, 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;
- 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 leaves your phone by itself. Uninstalling the app deletes all of it. If you sign in to Google Play Games, some of it is copied to Google as well — section 2 lists exactly what, and that is the only way any of it travels.
4. Third-party services
The app contains no advertising network, no analytics service and no crash-reporting service. One third party is in it, and only if you ask for it:
- Google Play Games Services (Google LLC) — the leaderboards, the achievements and the cloud save. It does nothing until you sign in, and you never have to. Section 2 says what it sends; Google’s Privacy Policy covers what Google then does with it.
Three things in the app hand something to another app on your phone, at your request, and none of them sends anything to us: “Privacy policy” in Settings opens this page in your browser, “Check” beside the version number opens the Play Store, 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.
- The app opens no connection of its own. It holds no internet permission — you can see that in Android Settings → Apps → Tiltrow → Permissions. 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. The game never talks to a network by itself, and there is no address it could talk to: we run nothing.
- 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. That is a deliberate design choice, and signing in to Play Games does not change it: the data goes to Google, never to us.
- No password to lose. The game has no login of its own. Play Games sign-in is Google’s, handled by your phone, and the app never sees a password.
6. How long data is kept
- On your phone: until you delete it. 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.
- By us: nothing, for no time at all. 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.
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 yousuf.stu@gmail.com and we will answer within 30 days.
8. Selling and sharing
We do not sell your data, and we never will. 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.
There is nothing to sell or share: we never have it in the first place.
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 never shows 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 never receive or see it.
10. Permissions
The app requests no Android permissions at all — no location, no camera, no microphone, no contacts, no storage access, and not even the internet permission. You can check this yourself: Android Settings → Apps → Tiltrow → Permissions.
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 ever appears.
11. Internet
The game works fully offline, in both modes and on the Daily tray, and it never waits for a network to let you play. The app itself opens no connection: it has no internet permission, so Android would not allow it to.
Two things do reach the internet, and both go through other parts of your phone 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 them and sends them the next time it can.
- “Check” beside the version number in Settings, when you tap it — it asks the Play Store whether a newer version exists. Nothing about you is sent; it is the Play Store asking about the app, not about you.
The things that open other apps on your phone are described in section 4.
12. Advertising
The app 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 the game 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. It collects no personal data from anyone, so it collects none from children either, and it shows no ads.
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 yousuf.stu@gmail.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 has ever been 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 yousuf.stu@gmail.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. 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.
