Privacy Policy
No Data Collection
The app does not collect, transmit or store any personal information on external servers. It makes no network requests; all content ships inside the app.
What Stays on Your Device
The following data is stored locally with Android DataStore and never leaves your device:
- Stars earned on each level (which also decide which levels and sets are open)
- Your best time on each solved level
- Record stats: levels solved, perfect solves, hints used, total solving time and number of plays
- Settings: Show timer and Haptics on or off
- Whether you have already seen the welcome screen
An unfinished level is not saved. You can erase your stars, best times and Record stats at any time in Settings → Reset progress (type RESET to confirm). Uninstalling the app or clearing its data in Android settings deletes everything permanently.
No Analytics or Advertising
The app contains no analytics SDK, no advertising network, no crash-reporting service and no third-party code that sends data anywhere.
No Accounts
You do not need to create an account, sign in or provide any contact information to use the app.
Permissions
The app does not request any special Android permissions.
Diagnostic Information
If the app crashes, Google Play may collect a standard crash report through Android system diagnostics, depending on your device settings. We do not receive any personal information from these reports.
Children
The app does not knowingly collect personal information from anyone, including children under 13.
Changes
If this policy changes, the new version will be posted on this page with a new “Last updated” date.
