1. Purposes of personal data processing

The developer processes personal data for the following purposes:

  1. Member identification and login — To identify your account and keep you logged in, your email address is used.
  2. Providing heart rate-based exercise intensity settings The developer processes information such as age, gender, and exercise experience to calculate your maximum heart rate, set heart rate zones, and provide personalized exercise intensity guidance.
  3. Storing and synchronizing exercise records The developer processes exercise records, heart rate records, heart rate zones, and exercise settings that you enter or that are generated while using the app, so that you can view them in the app and synchronize them across devices or with the server.
  4. Service operation and error response — Personal data may be processed to check for errors, respond to inquiries, prevent abuse and provide a stable service.

The developer does not use personal data for any purpose other than those described above. If the purpose of use changes, the developer will take necessary measures in accordance with applicable laws.

2. Personal data items processed

The developer may process the following personal data to provide the service:

Category Items Processed Collection Method
Account information Email address Collected when the user logs in
Exercise setting information Age, gender, exercise experience, maximum heart rate, heart rate zone settings Entered directly by the user in the app or generated through in-app calculations
Exercise record information Exercise date, exercise duration, exercise intensity, heart rate records, exercise records by heart rate zone, etc. Entered or generated while the user uses the app
