There’s nothing implying that Apple itself is doing anything with this data, instead a user’s location history is stored in a file called consolidated.db, which regularly collects GPS information. It can also be saved on a computer when a user syncs an Apple device with iTunes.
Allan and Warden presented a visualization of this location tracking at the Where 2.0 conference. Here’s an app that Warden built to map stored location data, should you want to try to view your own history.
The programmers’ concern is why Apple is storing the information to begin with, and the company’s intentions.
The New York Times’ Nick Bilton points out the complexities of this debate:
