Privacy Policy

Rest Coach is an AI sleep-coaching app for iOS and Android, operated by Rest Coach LLC(“Rest Coach”, “we”, “us”). To coach you well we process your health metrics, your voice during sessions, and a coaching memory we build over time. Here is exactly what that means: what stays on your device, what syncs to your account, and the controls you have.

Where your data lives

Raw health records

Sleep, heart rate, HRV, and other signals from Apple Health / HealthKit and Android Health Connect.

Read on device

Daily summaries & coaching memory

Computed daily metrics, your dossier, and your commitments so your history and coach persist across devices.

Synced to your account

Voice during sessions

Streamed through our voice proxy to Google Gemini for real-time coaching. No recordings are kept.

Not stored

We do not sell your data or use it for advertising, and you can delete everything at any time.

Health & fitness data (Health Connect & Apple Health)

With your permission, Rest Coach reads health and fitness data from Apple Health / HealthKit on iOS and Android Health Connect on Android to personalize your coaching and analytics. Depending on what your connected sources provide, this can include sleep (duration and stages), heart rate and resting heart rate, heart-rate variability (HRV), respiratory rate, blood oxygen (SpO₂), body temperature, blood pressure, steps, distance, active calories, exercise sessions, weight, and height.

How this data is handled:

  • Raw health records are read on your device to compute your sleep score, stages, trends, and coaching context.
  • We sync daily summary metrics derived from this data (for example: sleep duration and stages, HRV, resting heart rate, steps, and a computed stress/sleep score) to your account on our backend, so your history, trends, and reports persist beyond the platform's retention window and are available across your devices.
  • You can revoke access at any time in iOS Settings → Health, or in Android Settings → Health Connect. You can delete the synced data by deleting your account (see “Your choices & deletion”).

Optional wearable integrations (Whoop / Oura)

If you choose to connect a Whoop or Oura Ring account:

  • The OAuth sign-in and token exchange are handled through our backend. Your wearable access tokens may be stored encrypted on our backend and/or on your device so we can retrieve your recovery, readiness, and sleep data.
  • Wearable-derived data is used as coaching context and may be included in the daily summary metrics synced to your account.
  • You can disconnect a wearable at any time in the app's Settings, which removes the stored tokens.

Voice coaching sessions

Voice sessions are powered by Google's Gemini model:

  • Your microphone audio is streamed through our backend voice proxy to Google Gemini for real-time processing. We do not store audio recordings.
  • After a session, the transcript is sent transiently to our backend to generate an AI summary and to extract coaching memory (below). The transcript is processed for that purpose and is not retained as a standalone record; the resulting session summary is stored on your device and on your account.

Coaching memory

To act like a coach that remembers you, Rest Coach builds a “coaching memory” from your sessions:

  • Durable facts about your sleep habits and preferences, a profile (“dossier”) summarizing your goals, chronotype, and what's working, and commitments (steps you agree to) that the coach follows up on.
  • This memory is stored on your device and on your account (our backend), and is generated and updated using Google Gemini. It exists only to personalize your coaching and is never sold or used for advertising. Deleting your account erases it everywhere.

Account information

When you create an account we store your email address, a bcrypt-hashed password, and your display name on our backend, and issue a signed (JWT) session token. We use this only to authenticate you and sync your data. We do not sell or share your account information.

Subscriptions

Subscriptions are processed by the Apple App Store and Google Play. We do not receive or store your payment-card details; we receive only your subscription status to unlock premium features.

On-device protection

Sensitive data on your device (your authentication / OAuth tokens and your local health and coaching database) is excluded from your platform's automatic cloud backup, so it is not copied to iCloud or Google Drive, or transferred device-to-device.

Your choices & deletion

  • Revoke health access: iOS Settings → Health, or Android Settings → Health Connect.
  • Disconnect wearables: in-app Settings.
  • Delete your account and all data: Settings → Account → Delete Account. This permanently deletes your account, sessions, synced metrics, coaching memory (dossier + commitments), and stored wearable tokens from our backend, and wipes your local Rest Coach data on the device.
  • Request deletion by email: if you can’t access the app, email privacy@restcoach.ai with the subject “Account Deletion Request” and the email on your account, and we’ll delete your data.
  • Export your data: Settings → Export Session Data.

Data we do NOT collect

  • Precise location, contacts, calendar, or browsing history
  • Advertising identifiers or any data used for advertising
  • Any data not described in this policy

Third-party services

Each third party processes data under its own privacy policy:

  • Google Gemini API: AI voice coaching, session summaries, and coaching-memory generation
  • Apple Health / HealthKit & Android Health Connect: health & fitness data access (with your permission)
  • Whoop API / Oura API: wearable data access (optional, with your permission)
  • Apple App Store & Google Play: subscription management
  • Our hosting / backend (restcoach.ai)

Children's privacy
