Summary

MyHealthRings is privacy-first. The app reads health information from Apple Health (HealthKit) to compute wellness rings and recommendations. No accounts, no servers, no analytics, no ads. Your health data stays on your device and never leaves it unless you export it yourself.

What Data We Access

If you grant permission, the app may read the following from Apple Health (HealthKit):

• Heart Rate Variability (HRV)
• Sleep (total time, deep, REM, awake)
• Resting Heart Rate
• Respiratory Rate
• Wrist Temperature
• Heart Rate (including during workouts)
• Steps and Apple Watch workouts (for zones/strain)

Write access: Currently, the app does not write data to HealthKit.

How We Use Your Data (On-Device Only)

We use your HealthKit data locally on your device to provide the app's core features. We do not transfer your data to our servers (we don’t have any), sell or share your data, or use it for advertising.

Your Rights & Data Control

You are in full control of your data. Because all processing happens on your device, you can exercise your rights directly by:

• Revoking Health permissions in Settings → Health → Data Access & Devices.
• Deleting specific data directly in the Apple Health app.
• Deleting the MyHealthRings app to remove its local data.

Medical Disclaimer

MyHealthRings provides general wellness information only. It is not a medical device and does not diagnose, treat, cure, or prevent any disease. Always consult a qualified healthcare professional for medical concerns.
