Your iPhone is tracking you like Lester Freamon from The Wire

Freq Locations

Since iOS 7 came out in 2013, your iPhone’s Location Services has included a little-known feature called Frequent Locations, which keeps very detailed track of every distinct location you visit. How detailed? This, precisely, was when I was in my apartment over a three-day period last month:

Freq Locations

All told, my phone recorded all 33 different locations I’ve visited in NYC since April 15, including 84 visits to my apartment and 54 visits to my office, down to the minute and a ~130-foot radius. The feature is on by default if you’ve got Location Services switched on, so you can find your information by opening the Settings app and going to Privacy > Location Services > System Services (at the bottom) > Frequent Locations. You can also turn the feature off if you wish.

Apple says the feature is used to learn your favorite places and the data is kept only on the phone:

Your iPhone will keep track of places you have recently been, as well as how often and when you visited them, in order to learn places that are significant to you. This data is kept solely on your device and won’t be sent to Apple without your consent. It will be used to provide you with personalized services, such as predictive traffic routing.

It’s likely that Verizon, AT&T, Sprint, and the NSA (until recently) are collecting this same sort of data about you regardless of what sort of phone you use, except that these organizations do not share Apple’s public commitment to privacy. (via @dunstan)
