With the Find My iPhone feature, you can track the location of your iPhone, iPad, or Mac if it’s lost or stolen. However, there may be times when you don’t want your location to be tracked. For example, you may be in a sensitive location or you may simply want to keep your location private. In this case, you can freeze your location on Find My iPhone.
Freezing your location will stop Find My iPhone from updating your location. This means that anyone who is tracking your device will not be able to see your real-time location. However, they will still be able to see your last known location.
