Health Data

Last updated 8 November 2026 · Adam Richard Turner, trading as Sleep Coach

Sleep Coach can read your sleep from Apple Health or from Fitbit and Pixel Watch through Google. Connecting either is optional — you can keep a diary by hand instead. This page sets out exactly what is accessed and the rules that apply.

Apple Health (HealthKit)

  • Read: Sleep Analysis samples (in bed, asleep, and sleep stages) written by Apple Watch, iPhone or other apps you have allowed to write Sleep.
  • Write (optional): your planned sleep window, so it can appear beside Sleep in Health.
  • Why: to fill your diary, show your summary and charts, and suggest a sleep window. Nothing else.
  • Control: permission is managed by iOS. Revoke it at Settings → Health → Data Access & Devices → Sleep Coach, or switch source in More → Sleep data.

HealthKit data is never used for advertising, marketing or data mining; is never sold or disclosed to third parties such as advertisers, data brokers or information resellers; and is never stored in iCloud. It is shared with the AI provider only when you choose to use Chat or Sleep review and only to generate your reply, as described in the AI Transparency notice.

Fitbit and Pixel Watch (Google Health API)

  • Access: read-only access to your sleep sessions and stages. No other Google Health or Fitbit data is requested.
  • How: you sign in to Google and grant access. An encrypted access grant is stored on the Sleep Coach server and used only to fetch recent sleep so it appears in your diary.
  • Control: switch away from Google Health in More → Sleep data to delete the grant, or remove Sleep Coach at myaccount.google.com/permissions. Deleting your account also deletes it.

Sleep Coach’s use and transfer of information received from Google APIs to any other app will adhere to the [Google API Services User Data Policy](https://developers.google.com/terms/api-services-user-data-policy), including the Limited Use requirements. Google user data is used only to provide and improve the user-facing sleep features of the App, is not transferred except as needed to provide those features, comply with law, or as part of a merger or acquisition with your notice, is never used for advertising, and is never read by a human except with your explicit consent, for security purposes, or to comply with law.

What happens to imported nights

Turning off a source stops new imports. Nights already saved to your Sleep Coach account remain until you edit or delete them, or delete your account.
