GoBlu integrates with Apple HealthKit to provide activity rings, recovery insights, and to log your workouts back to Apple Health. This page explains what we read, what we write, and where the data goes.
Reads (opt-in)
Step count — daily step ring and Recovery card
Active energy — daily calorie ring and Recovery card
Apple Exercise minutes — daily activity ring
Resting heart rate — Recovery card readout
Heart-rate variability (SDNN) — reserved for future readiness scoring
Sleep analysis — Recovery card sleep summary and bedtime estimate
Body mass — to mirror Apple Health weight entries into your weight log
Writes (opt-in)
Workouts — when you finish a session, GoBlu writes a strength-training workout sample to Apple Health with the start/end time and estimated active calories
Body mass — when you log a new weight, we mirror it to Apple Health if you've granted write permission
Where the data goes
All HealthKit reads happen on-device. We do not transmit, sell, or share HealthKit data with any third party. We do not use HealthKit data for advertising, and we never use it to train AI models.
Revoke
You can revoke any HealthKit permission at any time in iOS Settings → Health → Data Access & Devices → GoBlu. Revoking will cause the corresponding feature to show "—" instead of a value.
