Can the Location Services tell me where my iPhone was this morning?
If location services are enabled, your iPhone maintains a log of Significant Locations. You can find them under Settings app → Privacy → Location Services → System Services → Significant Locations. Check for History section. Tapping on History will list the locations recorded by your iPhone.

 

You also have the option to view and delete the individually recorded location data.

 

If you are concerned about your privacy, you can also choose to clear the location data any time. This data is sensitive and handled very carefully by Apple. It is not shared with 3rd party apps, is encrypted and cannot be read by Apple.
