Puzzle Expression does not currently use its own analytics service.
If analytics is added in the future, this Privacy Policy will be updated before or when that feature is released.

The app is not directed to children under 13. We do not knowingly collect personal information from children under 13.

Clearing the app data from your device settings; or
Uninstalling the app from your device.
Puzzle Expression uses local device storage for gameplay data. No method of electronic storage or transmission is completely secure, but the app is designed to avoid collecting unnecessary personal information.
