Privacy Policy — Endorphun

Last updated: January 2026

Endorphun is developed by Fanny Wijaya Halim. This Privacy Policy explains how data is handled when you use the app.

Data Collection

Endorphun does not collect, store, or transmit personal data.

The app does not require accounts, logins, or user identifiers, and it does not use analytics or tracking technologies.

Health & Workout Data

Endorphun uses Apple HealthKit and WorkoutKit solely to write custom running workouts to the system Workout app on Apple Watch.

  • The app does not read health or workout history.

  • Health and workout data is handled by Apple’s system frameworks and remains on your device.

  • Endorphun does not store, process, or transmit this data externally.

All HealthKit usage follows Apple’s HealthKit guidelines and permission model.

Third-Party Services

Endorphun does not use third-party analytics, advertising, or crash reporting services.

Data Storage

Endorphun does not maintain its own data storage or backend servers. Workout configurations are passed directly to Apple’s system Workout app via WorkoutKit.

User Control

You control HealthKit permissions at any time through the iOS Settings app. Revoking permissions will prevent Endorphun from creating workouts.
