You know the little Location Services triangle in the top right of your iPhone’s status bar well. It floats there faithfully every day, representing modern technology’s obsession with location data. Knowing where you are and what you do on a daily basis is incredibly valuable to advertisers and merchants looking to sell the next “x because you where at x.” Knowing your location also makes apps and iOS smarter, which ultimately makes the experience of using your iPhone more seamless.
If you’ve had Location Services turned on, then you’ve already been giving Apple permission to silently track your every move. A new setting in iOS 7 called “Frequent Locations” makes how and to what level you are tracked more transparent, right down to the minute you left your house yesterday.
