Privacy

PulseLoop is built local-first, which is the whole point.

  • No vendor cloud, no account. The app talks to the ring directly over Bluetooth LE.
  • Your data stays on your phone, persisted locally (SwiftData on iOS, Room on Android).
  • AI Coach is off by default and optional. You can use the app without it; it is disabled by default in Settings.
  • Nothing leaves the device except a coach question you explicitly ask — that single request goes to whichever LLM provider you configured, with the API key you supply.
  • API keys are stored securely on-device — the iOS Keychain, or Android's EncryptedSharedPreferences.

Not a medical device

PulseLoop is not a medical device and is not a substitute for professional medical advice. Treat all readings as approximate. Always consult a clinician for health concerns.

For contributors

The promise that your health data stays on your device is a hard constraint. Any change that affects what data leaves the phone, or how it's stored, must be called out clearly in the PR description and will get extra scrutiny. Never commit secrets, API keys, or real personal health data. See Contributing.
