The little-known feature is buried deep within your iPhone settings, and shows your exact movements over the past few months.
What is iPhone Significant Locations?
Your iPhone has a feature called Location Services, which uses your location to improve various features on the device.
This includes Significant Locations, a rolling log of your real-world movements, which are then used to offer other services.
For instance, if your iPhone knows about your daily commute, it can provide tailored timing information about your journey.
"Allow your iPhone to learn places significant to you in order to provide useful location-related information in Maps, Calendar, Photos and more," Apple explains.
Is iPhone Significant Locations safe?
You might be panicking that Apple is keeping a log of your every move, but that's not quite the case.
