Privacy Policy

Effective March 21, 2026

1. Who We Are

PaceKit is developed by CPKM ("we", "us", "our"). PaceKit is a free iOS application that provides AI-powered race day coaching for runners.

2. Data Collected During a Race

While a race is active, PaceKit accesses the following data on your device:

• Location (GPS) — Used to calculate distance, pace, and course position. Location tracking stops when the race ends.
• Heart Rate — Read from Apple Watch via HealthKit or a paired Bluetooth heart rate sensor. Used for real-time coaching and HR zone calculations.
• Health Profile — VO2 max, resting heart rate, age, and weight from HealthKit. Used to personalize coaching advice (e.g., Karvonen HR zones, fueling guidance).
• Microphone — If you speak to your coach, audio is processed on-device using Apple's speech recognition. Transcribed text is sent to our coaching service. Audio is not recorded or stored.

3. Data Sent to Our Services

AI Coaching (Supabase / Anthropic):

Coaching messages are generated by sending race metrics to our server, which forwards them to Anthropic's Claude AI. Data sent includes:

• Current pace, heart rate, distance, elapsed time, mile splits
• Health profile summary (age, weight, VO2 max, resting HR)
• Voice transcripts (if you speak to your coach)
• Course context and weather conditions

This data is used solely to generate coaching responses and is not stored by CPKM after the request completes. Anthropic's data handling is governed by their privacy policy.

Voice Synthesis (RunPod):

• Coaching message text is sent to a text-to-speech service to generate spoken audio.
• No health data, location data, or personal identifiers are included.

Live Tracking (Optional):

If you enable live tracking, your real-time location, pace, and heart rate are shared with spectators via a tracking link. This data is transmitted every few seconds during the race and is deleted after the race ends. Live tracking is off by default.

4. Account & Race History

You can optionally sign in with Apple to sync race results. If you create an account, the following is stored on our servers (Supabase):

• Apple ID user identifier (anonymous UUID)
• Display name (from Apple Sign In, if provided)
• Race results: distance, time, pace, splits, heart rate stats, calories
• GPS route coordinates from your race
• Badges earned and crown leaderboard position

Account creation is optional. All core features — coaching, tracking, voice — work without signing in.

5. In-App Feed & Reactions

The welcome feed displays race updates and tips. You can react to feed entries with emoji. Reactions are stored anonymously using a randomly generated device identifier (not your Apple ID or advertising identifier). No personal information is associated with reactions.

6. Data Not Collected

• We do not use advertising identifiers (IDFA)
• We do not run analytics, telemetry, or crash reporting SDKs
• We do not track you outside of an active race
• We do not sell, share, or monetize your data

7. Weather Data

PaceKit displays weather forecasts using Apple WeatherKit. Weather data is fetched based on the race course location, not your personal location. Apple Weather legal attribution.

8. On-Device Storage

• Preferences — Coach selection, pace targets, and settings stored in UserDefaults.
• Credentials — Supabase session tokens stored in the iOS Keychain with kSecAttrAccessibleAfterFirstUnlock protection.
• Voice Unlocks — Earned voice unlocks stored locally and synced to your account if signed in.

9. Background Location

PaceKit uses background location only during an active race so tracking continues when your screen locks. The blue location indicator is always visible when background tracking is active. Location updates stop immediately when you end your race.

10. Children's Privacy

PaceKit is not directed at children under 13. We do not knowingly collect data from children.

11. Data Security

All network communication uses HTTPS/TLS encryption. Credentials are stored in the iOS Keychain. Server-side data is hosted on Supabase with row-level security policies.

12. Your Rights

You can delete your account and all associated data by signing out in the app. Race data synced to our servers will be removed. Local data can be cleared by deleting the app.

13. Changes to This Policy

If we update this policy, the revised version will be posted at this URL with an updated effective date. Continued use of PaceKit after changes constitutes acceptance.
