In order to provide you with information about events near you, the app sometimes needs to determine your approximate location. This is done using the phone's built-in GPS. The location is only used to determine which events are relevant to you. Each time a new location is retrieved the previous one is deleted, so it is not possible to track how your phone has moved over time.
SOS Alarm does not know who has downloaded the app and does not save or track any location information beyond what is described here.
If you have turned off location services on your phone, the app will not have access to your location. In that case no GPS information will be sent to SOS Alarm.
For the app to work as intended you need to allow "Always allow exact location" in your phone's settings.
