Sauna Log Privacy Policy

Effective date: 19 May 2026

Sauna Log helps users track sauna and steam room sessions from Apple Watch, including duration, heart rate, calorie values, and optional cold shower logging.

1. Information We Process

Sauna Log may process the following information on your device:

  • Heat session type, such as Sauna or Steam Room.
  • Session duration and timer preset.
  • Optional cold shower selection.
  • Heart rate during actively tracked sessions, if Health permission is granted.
  • Workout or session records written to Apple Health, if Health permission is granted.
  • Active and total calorie values where provided by Apple Health or Apple Watch.
  • Purchase-entitlement, free-trial, review-prompt, timer-setting, heart-rate-alert, and app-state information.

2. How Information Is Used

Information is used only to provide the app's core functionality: running heat session timers, displaying heart-rate and calorie metrics, saving sessions, writing eligible workout or session information to Apple Health, syncing app state between Apple Watch and iPhone, restoring purchases, and enabling unlock status.

3. Health Data and Apple Health

If you grant Health permissions, Sauna Log reads and/or writes data through Apple HealthKit solely to support the session tracking features you choose to use.

  • Health data is used only for app functionality you request.
  • We do not sell Health data.
  • We do not use Health data for advertising.
  • We do not use Health data for tracking or targeted advertising.
  • You can revoke Health permissions at any time in the Health app and iOS or watchOS settings.

4. Local Storage

Sauna Log stores data primarily on your devices. Some session and app-state information may sync between your paired iPhone and Apple Watch using Apple's device connectivity frameworks. We do not operate our own cloud backend for personal data storage at this time.

5. Purchases

Sauna Log offers a free trial and an in-app purchase to unlock unlimited use. Purchase processing is handled by Apple through the App Store and StoreKit. We do not receive your full payment-card details.

6. Sharing

We do not sell your personal data. We do not share your personal data with third parties for targeted advertising. Data may be processed by Apple services required to run the app, such as HealthKit, StoreKit, notifications, and Apple Watch/iPhone connectivity.

7. Retention and Deletion

Because data is stored on your devices, you control deletion by deleting sessions inside the app where supported, removing app permissions, uninstalling the app and deleting associated data, or managing Apple Health records in the Health app.

8. Children's Privacy

Sauna Log is not directed to children under 13, or the equivalent minimum age in your jurisdiction, and we do not knowingly collect personal information from children.

9. Your Choices

You can choose whether to grant Health permissions, revoke Health permissions at any time, decide whether to purchase the unlock, and contact us with privacy questions.

10. Changes to This Policy

This policy may be updated from time to time. When it changes, the effective date above will be updated.
