# [Android] What permissions are required for Android?

### Analysis of permissions required


The application needs access to certain information on your mobile in order to function.
To check that everything is functional: 
* Go to **Profile**
* Click on **Settings** at top right of screen
* Then **Follow-up and navigation**.
* Finally, click on **Permission required**.


If in this window, **the bar is green and at 100%, your application is perfectly configured**.

If this is not the case, click on the setting that is not active, and a window will open to access your phone's settings and activate authorization.

###### What do these authorizations do?

**Position**

This authorization is absolutely necessary to activate your GPS position, guide you during navigation and record your journeys.
****

**Disable battery optimization**

If battery optimization is not deactivated, the application can be shut down at any time by the system, cutting off navigation and trip recording.
****

**GPS position in background:**

The application collects location data to record your journeys and detect when you are cycling, even if it is closed.
Locations are only used to record your movements. 
It is therefore possible to disable this option if you do not use activity detection and/or do not wish to authorize gps position reading.

**Activity detection**

Our activity detection system relies on the activity recognition tool in your smartphone. Authorization for activity recognition (sometimes called physical activity) is required to detect and record your cycling activities.
