HRV Sync is designed with your privacy in mind. Here's how we handle your data:
Data Collection
HRV Sync does not collect, store, or transmit any personal data to external servers. All data processing happens locally on your device.
Garmin Account
The app connects directly to your Garmin account to fetch your HRV data. Your login credentials are stored securely in your device's Keychain and are never shared with third parties.
Health App
HRV data is written to the Health app on your device. This data stays on your device and is managed according to Apple's privacy policies.
No Analytics or Tracking
The HRV Sync app does not include any analytics, advertising, or tracking frameworks. This website uses Cloudflare Web Analytics for aggregate page views and performance without cookies, local storage, or user profiling. Garmin credentials and HRV data are not sent to website analytics.
