After the first installation, the app asks you to access the location of your smartphone. This happens for two reasons:
- By accessing the app, you can see your position relative to the position of your GRETA.
- To determine the distance between you and your GRETA, the app needs to know your current location.
If you have denied access first and want to enable it later, you will not be able to do it directly from the Prothelis app. In this case, go to the settings menu of your smartphone and allow the permission in the details of the Prothelis application.
