Privacy Policy

Last updated: 1 September 2026

Meow Puzzles does not collect any data. Not your name, not your email, not an advertising identifier, not a crash report — nothing leaves your device, because nothing is ever sent anywhere.

This policy covers the Meow Puzzles app (bundle identifier com.maomaosudu.maomaosudu) on iOS and Android. It applies to every version currently on the App Store and Google Play.

Data we collect

None. To be specific about what is not in this app:

• No analytics or telemetry SDK.
• No advertising SDK, and no advertising identifier (IDFA / GAID) is read.
• No crash or performance reporting service.
• No accounts, no sign-in, no cloud save, no leaderboards.
• No contacts, photos, location, microphone, camera or clipboard access.

The app has no server. There is nowhere for your data to go even if we wanted it.

What the app stores on your device

Your progress is saved locally, in the operating system's standard key-value store for apps — NSUserDefaults on iOS, SharedPreferences on Android. It stays inside the app's private sandbox, and it is never transmitted. In full, the app writes:

• save.<mode> — the board you left unfinished in each mode, so you can pick it up again.
• levels.<mode> — which levels you have unlocked.
• stats.<mode>.<level> — how many times you have cleared a level and your best time on it.
• perfect.<mode> — which levels you cleared without a mistake.
• lessonDone.<mode> — whether you have finished that mode's tutorial.
• catSkin — the cat appearance you picked.
• pref.sound, pref.haptic, pref.locale — your sound, vibration and language settings.

That is the complete list. None of it identifies you; all of it is about squares and cats.

Deleting your data

Open Settings → Clear progress inside the app. This erases every saved board, unlocked level and record listed above, and cannot be undone. Your sound, vibration and language preferences are deliberately kept — clearing your progress should not also reset the volume.

Deleting the app removes everything, preferences included. Since nothing was ever uploaded, uninstalling really is the end of it.

Permissions

On Android, the released app declares exactly one permission: com.maomaosudu.maomaosudu.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION. It is added automatically by the Android build system to keep the app's own internal broadcasts private to itself. It grants no access to anything of yours, and you will never see a prompt for it.

Notably, the released app does not declare the android.permission.INTERNET permission. On Android this is enforced by the operating system, not by us: an app without that permission cannot open a network connection at all. You do not have to take our word for the paragraphs above — you can verify it in the app manifest.

On iOS, the app declares no usage descriptions, because it asks for no protected resources. You should never see a permission prompt from Meow Puzzles.

Third-party software

The app is built with Flutter and uses a small number of open-source packages: shared_preferences (the local save file described above), audioplayers (plays sound files bundled in the app), package_info_plus (reads the app's own version number to show on the settings screen), plus Flutter's own localisation and icon packages.

None of them are advertising, analytics or attribution SDKs, and none of them open a network connection in this app.

Children

Meow Puzzles is suitable for all ages. Because it collects nothing, shows no ads, contains no purchases, has no chat, and links to nothing outside itself, it does not knowingly or unknowingly gather personal information from children. It is compliant with COPPA and the GDPR's provisions on children by construction rather than by policy.

Your rights

Laws such as the GDPR and the CCPA give you the right to access, correct, export or delete the personal data a company holds about you. We hold none, so there is nothing to access, correct, export or delete. The only copy of your progress is the one on your own device, and the Clear progress button hands you full control of it.

Changes to this policy

If a future version ever adds something that touches your data — advertising, analytics, cloud save, accounts — this page will be updated to say exactly what it does before that version is released, not after. The date at the top will change accordingly.
