Lookout makes the most efficient possible use of the Android phone's GPS receiver.
When a Locate is requested for an Android device, Lookout turns the GPS on to run the Locate and then turns it off again when the Locate is complete. This helps to conserve your phone's battery. Getting the best location results can take several minutes.
Lookout only uses GPS to pinpoint your location when you explicitly request it. If your GPS is enabled, that simply means that apps have the ability to utilize it. It does not mean the GPS is being used continuously or that your location is constantly being tracked.
Note: It is not possible for Lookout, or any other app, to enable GPS on Android devices.
