Badminton Rotation ("the app") is a fully offline teaching app. We respect your privacy.
None. The app does not collect, transmit, or share any personal data. It works entirely offline and does not require an account, internet connection, or any permissions.
Your preferences and learning progress (favorites, recently viewed rotations, practice results, language and playback settings) are stored only on your device using the system's local storage. This information never leaves your device and is removed when you delete the app.
The app contains no analytics, no advertising, and no third-party SDKs that collect data.
The app is suitable for all ages and collects no data from anyone, including children.
If this policy changes, the updated version will be posted on this page.
