Many smartphone applications, including default apps that come preloaded on the device, track your location for various purposes, regardless of operating system. While some of them simply do it into help serve targeted ads, plenty of smartphone apps require access to your location for more useful purposes, so it’s likely you have location services enabled on your devices for at least a few key apps.
If that’s the case, you should know the iPhone has a hidden menu that can show you a map of the exact places you have been tracked.
As detailed by Business Insider, the feature is quite easy to access if you know where to look – furthermore, it’s equally easy to turn this particular kind of location tracking off if you’re not comfortable with it.
What you have to do is go to Settings, then Privacy, then Location Services. Once there, tap the System Services menu and look for the Frequent Locations menu at the end.
If you then tap on that option, you’ll get a list of the recent places you have been, as tracked by the iPhone. Pressing on any of the listed cities will get you access to a map that will show you exactly where you have been tracked by your smartphone in that city.
From the same Settings page, you can choose to erase your location history and even turn the feature off so that your phone no longer saves your location data.
