Privacy Policy — RawPulse

Last updated: 2026-07-24

RawPulse is a small, independently developed Android app. This policy explains what data the app touches and — more importantly — what it does not do with it.

Short version

RawPulse does not collect, store, transmit, or share any personal data. Everything it reads stays on your phone.

What data RawPulse accesses

• Heart rate (BLE). RawPulse connects directly to your WHOOP band over standard Bluetooth Low Energy (the Heart Rate Service, 0x180D) to read live BPM readings, the same signal your WHOOP already broadcasts to apps like Peloton, Zwift, or Garmin.
• Derived metrics. From that raw BPM stream, the app computes things like live HRV (RMSSD), session min/avg/max, and heart-rate zone — entirely on your device, in memory.
• Age. You may enter your age in the app to improve the estimated max-HR (220 − age) used for zone calculations. This is stored locally in app settings on your phone.

What RawPulse does NOT do

• No account, sign-up, or login of any kind.
• No connection to WHOOP’s cloud API or servers — RawPulse talks to your band directly over Bluetooth and never touches your WHOOP account or credentials.
• No analytics, crash reporting, ads, or third-party SDKs.
• No data is ever sent off your device. There are no RawPulse servers to send it to.
• No location data is collected. (Android requires the Bluetooth-scan permission to be grouped with location for BLE scanning on some OS versions, but RawPulse does not read or use your location.)

Data storage

Heart-rate readings and derived metrics live only in memory while the app is running and are discarded when you stop streaming or close the app. Your age setting is stored locally via Android’s app preferences and is removed if you uninstall the app. Nothing is backed up to a cloud service by RawPulse itself (though your phone’s own OS-level backup, if enabled, may include local app settings — that’s controlled by your device, not by RawPulse).

Permissions

RawPulse requests:

• Bluetooth (scan/connect) — required to read your WHOOP’s HR broadcast.
• Notifications — to show the persistent streaming notification with a Stop button while the foreground service is active.

No other permissions are requested.

Third parties

RawPulse is not affiliated with, endorsed by, or connected to WHOOP, Inc. “WHOOP” is used only to describe compatibility with WHOOP devices. RawPulse does not share any data with WHOOP or any other third party, because it does not collect any data to share.

Changes to this policy

If RawPulse’s data practices ever change (for example, an opt-in Phase 2 integration with WHOOP’s cloud API), this page will be updated first, and the change will be reflected in the app’s release notes.
