The app should be asking to use location when you are using the app. In iOS under privacy>location services> it will say ‘While Using’ as opposed to ‘Always’. In Android I think it only shows the location permission as On. The app needs it when it first sets up and also when you are actively using it. This is to verify whether the phone is in the US, NA, or International as it behaves differently to not incur excessive international charges.
