1. Who We Are

Singletrack Health is an iOS and Apple Watch app for tracking cycling, running, walking, and other fitness activities. The app is developed by David Ham. If you have questions about this policy, contact us at support@singletrack.health.

2. Data We Collect

We collect only the data needed to provide the app's features:

• Account information — Your name and email address provided through Sign in with Apple. Apple may share a private relay email address rather than your real one at your discretion.
• Profile information — Username (handle), profile photo, height, weight, and date of birth that you optionally provide in the app.
• Location data — GPS coordinates recorded during active workouts to generate route maps and calculate distance. Location is only collected while a workout is in progress or while the app is in the foreground on the Activity screen.
• Health and fitness data — Workouts, distance, duration, elevation gain, heart rate, calories burned, and step count. This data is read from and written to Apple HealthKit with your permission.
• Social activity — Your public profile, activities you choose to share, followers, following relationships, kudos, and comments. This data is stored in Apple's CloudKit public database and is visible to other Singletrack Health users.
• Device information — Device token for push notifications (Apple Push Notification service). Used only to deliver notifications you have enabled.
• Contacts — If you use Find Friends, phone numbers and email addresses from your device address book are hashed on-device and compared against Singletrack Health users to surface people you know. Raw contact data is never stored or transmitted off your device.
• Weather data — The GPS coordinates and date of completed outdoor workouts are sent to Open-Meteo (open-meteo.com) to retrieve the ambient temperature at the time of your activity. Coordinates are rounded to approximately 11 meters of precision. Open-Meteo does not require account registration and does not receive any personally identifying information.
• Crash and diagnostic data — Anonymized crash reports including device model, iOS version, and stack traces are automatically sent to Firebase Crashlytics (Google) to help diagnose and fix bugs. No health or location data is included in crash reports.

3. How We Use Your Data

• To record, display, and sync your workouts and fitness history across your devices.
• To show your progress toward yearly fitness goals.
• To power the social feed, including following, kudos, and comments.
• To send push notifications you have opted in to (new followers, kudos, comments, goal milestones).
• To display the ambient temperature for completed outdoor workouts using the Open-Meteo weather service.
• To diagnose and fix crashes and technical issues in the app.

We do not use your data for advertising, profiling, or any purpose beyond operating the app.

4. Data Storage and Sync

Your private data — rides, goals, profile, and routes — is stored in your personal iCloud account via Apple's CloudKit private database. Only you can access this data. It syncs automatically across all your Apple devices signed in to the same Apple ID.

Social data you choose to make public (your handle, public activities, follow relationships) is stored in CloudKit's public database and is accessible to other users of the app.

Your health data in Apple HealthKit is governed by Apple's own privacy policies and remains on your device and iCloud account.

5. Data Sharing

We do not sell your data. We share data with the following parties only as necessary to operate the app:

• Apple — CloudKit (data sync), HealthKit (health data), Sign in with Apple (authentication), and APNs (push notifications). Apple's privacy policy applies to data processed by these services.
• Google Firebase (Crashlytics) — Anonymized crash reports to diagnose bugs. No health or location data is included. Governed by Google's privacy policy.
• Open-Meteo — Approximate GPS coordinates and workout date for temperature lookup after each outdoor activity. No personal information is transmitted. Governed by Open-Meteo's terms of service (open-meteo.com).

We do not share your data with any other third parties.

6. HealthKit Data

Singletrack Health requests access to Apple HealthKit to read and write workout data, heart rate, location routes, steps, and calories. This data is used exclusively within the app to display your fitness history and is never shared with third parties or used for advertising.

You can revoke HealthKit access at any time in Settings → Privacy & Security → Health → Singletrack Health.

7. Location Data

Location access is requested when you start a workout or open the Activity screen. We use precise location to record your route and calculate distance. Location is not collected in the background except during an active recording session, which is indicated by the blue location indicator in the iOS status bar.

You can manage location permissions at any time in Settings → Privacy & Security → Location Services → Singletrack Health.

8. Your Rights and Data Deletion

You can delete your account and all associated data at any time from within the app: Profile → Delete Account. This permanently removes your rides, goals, profile, and social data from CloudKit.

If you are unable to delete your data through the app, email support@singletrack.health and we will process your deletion request within 30 days.

9. Children's Privacy

Singletrack Health is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we will delete it promptly.

10. Changes to This Policy

We may update this privacy policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
