HealthKit Data
If you choose to have Movegain integrate with HealthKit then the application will have access only to the health data types you opt-in to access.
The health data read from HealthKit is used for display within the app. It is not collected or disclosed outside of your local installation of the app. Only those data types relevant to the app are accessed.
Movegain requests permission to write certain data types into your HealthKit data store. These are used when you perform a walking workout from an Apple Watch.
In no case is your health data ever transfered to a 3rd party. It is only ever kept within the application container of Movegain or transfered to your personal HealthKit data store as per your permission choices.
