Privacy policy
Effective date: 8 October 2026
This privacy policy explains how the Brain Twisters app for Android ("the app") handles your information. In short: the app does not collect, share or sell any personal information.
Information we collect
None. The app has no account or sign-up, and it doesn't ask for your name, email address, location, contacts, photos or any other personal information. It doesn't connect to the internet, so nothing you do in the app is sent to us or to anyone else.
Information saved on your phone
To work, the app saves the following on your phone only:
- your settings, such as style, theme, text size, language, sound, vibration and reminder time;
- your points, coins, streaks, streak freezes and the days you played;
- unfinished games and puzzles, so you can continue them;
- puzzles made in advance, ready for your next game.
This information stays in the app's private storage on your phone, and we can't see it. It is not included in Android backups or phone-to-phone transfers. You can delete your progress at any time with Settings → Your data → Reset all progress (your settings stay), or delete everything by uninstalling the app.
Permissions
- Notifications
- Used only if you turn on the daily reminder, to show it at the time you choose.
- Run at startup
- Sets your daily reminder again after the phone restarts.
- Vibration
- Buzzes on mistakes and at the end of a game, if Vibration is on.
The app doesn't ask for internet access, location, camera, microphone, contacts or storage permissions.
No ads, analytics or tracking
The app contains no advertising, no analytics, no crash reporting and no tracking, and it uses no third-party services that collect data.
Google Play
If you download the app from Google Play, Google may collect information as described in Google's own privacy policy. As the developer, we only see the summary statistics Google Play gives developers, such as the number of installs and crash reports, and these don't identify you.
Children
The app is suitable for players of all ages. It doesn't collect personal information from anyone, including children.
Sharing and selling
We don't share or sell any information, because the app doesn't collect any.
Changes to this policy
If this policy changes, the new version will be posted here with a new effective date, and shown in the next version of the app.
