How Apps Use Your Photos to Track Your Location

Are you sharing photos online? If so, you might want to consider how much of your privacy and the privacy of your family you are giving up.

Felix Krause’s iOS app DetectLocations shows you just how much apps can learn about your past (and future) location through your photos’ EXIF data. Grant it camera access and it will show you where you took all your photos, whether you were in a vehicle when you took them, and your likely routes between each photo location.

You can limit access to past photo data by moving everything out of your camera roll before you grant an app permission. But that won’t stop an app from spying on any photos going forward.
