Your iPhone stores a comprehensive catalog of where you’ve taken it in addition to when you took it there, it uses your location for targeted ads, and it sends your location to Apple for no other reason than to provide Apple with “Diagnostics & Usage.” But, don’t worry, this invasion of privacy can be stopped with the toggling of a few virtual switches.
First, let’s stop your iPhone from creating a detailed database of everywhere you’ve ever taken it. To do so, open Settings, then scroll down and tap “Privacy.” Next tap “Location Services” and scroll down until you see “System Services” and select it. Tap “Frequent Locations” and you’ll see the list of everywhere you’ve been with your iPhone. Now, to stop your iPhone from continuing to document where you’ve been with it, just turn off Frequent Locations.
Second, let’s stop letting your iPhone serve you targeted iAds based on your location. So, from the Frequent Locations screen in the Settings app, go back to the previous page, otherwise known as the System Services page, by tapping the blue back arrow labeled “System Services” in the top left corner of the screen. Now turn off Location-Based iAds.
Lastly, let’s stop letting Apple use your iPhone’s location data for “Diagnostics & Usage,” whatever that’s supposed to mean. To do so, just scroll down in the page in the Settings app that you’re in right now and set the switch next to “Diagnostics & Usage” to off.
