Map SDK Integration

The integration of the third-party map SDK by ZenRing aims to provide users with the functionality to create outdoor workout route and calculate workout distance. To ensure smooth operation, we request users' permission for both location access and background location tracking. If permission is not granted, the app will be unable to provide outdoor workout route planning and distance calculation features.

Background Location Permission

The background location permission allows the ZenRing app to continue tracking your workout location even when running in the background. This ensures the app can map your workout route and calculate distance without affecting the usage of other applications. Additionally, it optimizes battery usage by providing ZenRing's workout features efficiently when your phone screen is off.​​
