Privacy Policy for Heavy Protocol

Last Updated: December 17, 2025

Your privacy is important to us. This policy explains how Heavy Protocol (“we”, “us”, or “our”) handles your data.

1. Data Collection and Storage

Heavy Protocol is a local-first application.

• Personal Data: All your body measurements, workout logs, and routine data are stored locally on your device (and in your personal iCloud if you have enabled iCloud Backup).
• No External Servers: We do not operate a backend server. We do not transmit your workout data to any third-party cloud service. We cannot see, access, or sell your data.

2. HealthKit Integration

Heavy Protocol integrates with Apple’s HealthKit to sync your workout data (e.g., body weight, calories burned, workout duration).

• Reading Data: We read body weight data to visualize your progress charts.
• Writing Data: We write completed workouts to the Health app so they contribute to your activity rings.
• Privacy: This data is never used for marketing or shared with third parties. It stays within the Apple Health ecosystem on your device.

3. Analytics

The app does not use third-party analytics SDKs (like Google Analytics or Mixpanel). Any crash reports or usage metrics are provided solely through Apple’s opt-in “Share with App Developers” feature, which is anonymized.
