Google Health data disclosure
Aurin (Petr Fitness Data) is a personal training service that organizes training history, generates strength workouts, uses cycling context, and supports nutrition workflows.
With your authorization, the service may read fitness, health-metric, sleep, and nutrition data from Google Health. It may also add nutrition logs to Google Health when you ask the service to record food or drinks. This data is used only for the requested training and nutrition features.
The service can process training and fitness data from connected services, including Google Health data that the account owner has authorized, in order to provide these requested workflows.
Two optional permissions are requested separately: adding weight records to Google Health (weight you log in Aurin or Intervals.icu) and reading your date of birth from your Google Account to fill in your age.
Aurin’s use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
The use of information received from Google Health API and/or Developer Tools will adhere to the Google Health API Developer and User Data Policy, including the Limited Use requirements.
