Privacy Policy for Heavy Protocol

Last Updated: January 9, 2026

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. Backup: Data may be backed up to your personal cloud storage (e.g., iCloud or Google Drive) if you have enabled device backups.
• 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. Health App Integration

Heavy Protocol integrates with platform health services (Apple HealthKit on iOS and Health Connect on Android) to sync your workout data.

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

3. Analytics

The app does not use third-party analytics SDKs. Any crash reports or usage metrics are provided solely through platform-standard tools (Apple’s “Share with App Developers” or Google Play Console), which are anonymized.
