Privacy Policy

1. Information We Collect

When you create an account, we collect your name and email address. When you connect third-party services (such as WHOOP or Withings), we collect health and fitness data from those services, including but not limited to recovery scores, heart rate variability, sleep data, strain data, weight, and body composition measurements.

2. How We Use Your Information

We use your data solely to provide the VitalTrends service — displaying your health trends and enabling data exports. We do not sell, rent, or share your personal or health data with third parties for marketing or advertising purposes.

3. Data Storage & Security

Your data is stored in encrypted databases. All OAuth tokens used to access third-party services are encrypted at rest. We use HTTPS for all data transmission. Access to your data is strictly scoped to your account — no other user can access your information.

4. Third-Party Services

We integrate with WHOOP and Withings via their official OAuth2 APIs. When you connect these services, you authorize us to read your health data. You can disconnect these services at any time from your account settings, which will stop further data syncing.

5. Data Retention & Deletion

Your data is retained for as long as your account is active. You may delete your account at any time from your profile settings, which will permanently remove all your data, including synced health records and OAuth tokens.

6. Cookies

We use essential cookies for authentication and session management. We also store your theme preference (dark/light mode) in your browser's local storage. We do not use tracking or advertising cookies.

7. Changes to This Policy

We may update this privacy policy from time to time. We will notify registered users of any material changes via email.

8. Contact

If you have questions about this privacy policy or your data, please contact us at hello [at] vitaltrends [dot] net.
