Pulse OS Health Sync is a companion iOS app that reads measurements from Apple Health on your iPhone and sends them to your Pulse OS record. It is only useful alongside a Pulse OS account and does nothing on its own.
What it reads: heart rate variability, resting and live heart rate, respiratory rate, blood oxygen, blood pressure, steps, active and resting energy, exercise minutes, distance, body weight, body temperature, VO₂ max, sleep stages and duration, and workout sessions. It reads only the categories you permit when iOS asks, and you can change those at any time in Settings › Privacy & Security › Health.
The app never writes to Apple Health. It requests read access only, so nothing it does changes the data on your phone.
Alongside each batch the app sends the name your iPhone is set to, which it uses to tell one device from another when a member syncs from more than one. If your device name contains your own name, that name reaches us with the readings.
Health data collected through the app is used to build your own baselines and to show change over time to the care team you are enrolled with. It is never used for advertising, never sold, never shared with data brokers, and never used to train third-party models.
Turning it off: background sync can be switched off from the app's main screen at any time, and signing out stops collection immediately. Removing the app stops all collection. Data already sent is retained under the retention terms below until you request deletion.
