Privacy Policy · Package site.drumbeat.golfphysics · Effective 2026-07-23
This app does not collect any personal information. It has no server of its own and transmits no user data. The camera feed, your practice records and your settings are processed and kept entirely on your device.
The app holds the internet permission solely for Google Play in-app billing (purchase and restore); that communication is handled by Google. The app uses the network for nothing else.
The "Posture Analysis" feature uses the camera.
The camera feed is displayed live and discarded immediately.
Nothing is saved as a photo or video.
Nothing is transmitted to any server.
Pose (joint position) detection runs on an on-device AI model (Google MediaPipe). No network access is involved.
If you deny camera permission, every feature except Posture Analysis still works.
You can revoke the permission at any time in system settings.

Contents
Practice records
Timing-game scores and club head speeds, carry-challenge results, timestamps
Purchase state
Whether Premium has been unlocked
App settings
Whether onboarding has been shown, etc.
None of this leaves your device. You can delete all of it at any time from the "Practice Records" screen, and it is removed when you uninstall the app.
The Premium unlock is handled by Google Play in-app billing. Payment details such as card numbers are handled by Google and are not accessible to this app. The app stores only whether a purchase was made.
We do not share or sell personal information to third parties.
The app contains no advertising.
The app uses no behavioural analytics.
Because the app collects no personal information, it collects none from children.
The carry, ball-flight, swing simulations and posture feedback are physics approximations intended for education. They do not replace measurement hardware (launch monitors) or instruction from a qualified coach.
If this policy changes, we will update this document and the app store listing.
