Health Data Policy

Effective Date: April 5, 2026

We Fast Together ("WFT", "we", "us", or "our") is committed to protecting the privacy and security of your health information. This Health Data Policy supplements our Privacy Policy and explains specifically how we handle health-related data.

I. MEDICAL DISCLAIMER & AGE REQUIREMENT

This application is rated 18+ on the App Store. Users under 18 may only use the Service with parental or legal guardian consent.

We Fast Together is NOT a medical application and does not provide medical advice. Fasting involves significant dietary changes that may not be suitable for everyone. You engage in fasting practices entirely at your own risk. We strongly recommend seeking guidance from a qualified medical professional before starting any fasting regimen.

II. APPLE HEALTHKIT INTEGRATION

WFT integrates with Apple HealthKit to provide optional health-related features. HealthKit access requires your explicit opt-in permission for each data type.
