Invoxia never uses your location data for any purpose other than giving you the best possible experience with your GPS Tracker.
When your Tracker is moving and detects that it is within range of your smartphone, it asks the Invoxia GPS app to provide a location on its behalf. This significantly preserves the Tracker's battery, which can then be used when you really need it, that is, when the Tracker moves while you are not nearby.
This does not use much of your phone's battery and can make a big difference to how often you need to charge your Tracker.
This is why, for the best possible experience, you should allow the Invoxia GPS app to always locate you, including in the background.
