Privacy Policy

Effective 19 June 2026 · Applies to DrumPulse for Apple Watch and its iPhone companion app.

What DrumPulse accesses, and why

DrumPulse needs a few on-device permissions to do its job. It asks for each one, and you can decline or revoke any of them at any time in Settings. All processing happens on your device.

• Motion & fitness (CoreMotion). The watch reads wrist-motion data to detect your drum hits, measure your tempo, and tell when you're rushing or dragging. Motion data is processed in real time on the watch and is not stored as raw motion or sent anywhere.
• Heart rate & body mass (HealthKit, read). While a session runs, the app reads your heart rate to show it on your wrist, and may read your body-mass sample to estimate calories burned. This data is read on-device and is never transmitted off your device by DrumPulse.
• Workouts (HealthKit, write). When you finish a session, DrumPulse saves it to Apple's Health app as a workout (duration, active energy, heart rate). This data lives in Health under your control; you can delete it in the Health app at any time.

Where your sessions are stored

Your session history (timing scores, tempo, dynamics, and similar summaries) is stored locally on your Apple Watch. When your watch and iPhone are paired and in range, sessions are synced to the DrumPulse companion app on your iPhone so you can review them on a larger screen. This sync happens directly between your own two devices over Apple's encrypted device-to-device connection (WatchConnectivity). DrumPulse does not upload your sessions to any server or cloud service.

What DrumPulse does not do

• It does not collect, sell, or share your personal data.
• It does not use any analytics, advertising, or tracking SDKs.
• It does not track you across apps or websites.
• It has no user accounts and requires no sign-in.
• It contacts no servers operated by the developer or any third party.

Third parties

DrumPulse uses no third-party services, no third-party SDKs, and shares no data with anyone. The only Apple frameworks involved (HealthKit, CoreMotion, WatchConnectivity) operate on your devices under your permission.

Children

DrumPulse is not directed at children and collects no personal information from anyone, regardless of age.

Your control & data deletion

You are in full control of your data. You can revoke motion or Health permissions in the Settings app at any time, delete individual sessions inside DrumPulse, delete workouts in the Health app, and remove all DrumPulse data by deleting the app from your watch and iPhone. Because nothing is stored off your devices, deleting the app removes the app's data.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new effective date. Material changes will be reflected in a future app update.
