Hal will ask you for permission the first time you open the GPS Tracker. If you dismissed his initial request or have turned off location services since, you will need to go into your phone’s settings to allow Run with Hal to access your location.
Make sure to allow Run With Hal to access your location Always or your GPS will not track properly if you switch between apps, or put your phone to sleep while you're running.
Run With Hal never accesses your location when you're not using the GPS and does not share your data with any third parties.
