INTERLOCKING TILE

1The short version

Interlocking Tile is an offline puzzle game. There are no accounts, no ads, no analytics and no servers.

The app does not request internet permission, so it cannot send your information anywhere. Everything you enter stays on your phone.

2What is stored on your device

• Profile (only what you type or choose): first name, second name, username, optional email, optional country, optional “about me” text and an optional profile photo.
• Game data: levels cleared, stars, best times, moves, total play time, your current level and your settings (music, sound effects, vibration, tile theme).
• Certificate data: a random certificate number and the date your profile was created.
• Error log: a small text file of technical events (for example app errors, your Android version and phone model) so problems can be diagnosed. It never leaves your phone unless you choose to copy or share it.

3How it is used

Only to run the game: to show your profile and rank, remember your progress, create your ranking certificate and fix problems. It is not used for advertising, profiling or sale.

4Sharing

Nothing is shared automatically. If you tap Share on your ranking certificate, Android’s share sheet opens with the certificate image and its verification code. Your email and country appear only if you left them switched on; you can hide them first.

The same applies to the log screen’s Share button. Once you send something to another app or person, that app’s own policy applies.

5Photos

Your profile photo is chosen with Android’s photo picker, so the app never gets access to the rest of your photos. A square 512 px copy is saved in the app’s private storage. You can remove it any time from My Profile.

6Permissions

The app requests one permission only: vibration (for haptic feedback). It does not request internet, location, contacts, microphone, camera or storage permissions.

7Third-party code

The app uses open-source libraries (Android Jetpack and ZXing for drawing QR codes). They run entirely on your device and do not collect data.

8Keeping and deleting data

Data stays until you clear the app’s storage or uninstall the app (Android Settings › Apps › Interlocking Tile › Storage › Clear data). You can also edit your details, hide your email and country, or remove your photo inside the app.

If automatic backup is on for your phone, Android may include the app’s data in your Google backup. That is controlled by your device and Google settings.

9Certificates and security

Input is filtered and checked before it is stored, and data is kept in the app’s private storage. Ranking certificates carry a signed code that shows if the printed details were edited. This detects changes; it cannot stop someone copying a picture.

10Children

The game collects nothing on any server, so it does not collect children’s data. Parents should supervise any name, email or photo a child enters.

11Changes and contact

If this policy changes, the new version will be shown in the app. Questions or requests: open an issue on this project’s Issues page.
