Go to the privacy menu in the settings and under Location Services tap on System Services. In this section, you’ll see all the services which have been tracking your location, like cell network, traffic, etc, which are essentially aimed at improving your overall experience with the service and offer accurate location-related information.
Once you scroll all the way to the bottom of the list, you’ll find the Pandora’s box- Frequent Locations. Tap on it and voila, your history is out.
The history of your locations show the exact places you’ve visited in the past, complete with the number of visits and since when have you been frequenting the place.
So if you were at the city pub that one eve you excused from dinner at home saying you were working late, it wouldn’t take your spouse much to find out what exactly the nature of work you had. Solution? Turn off the frequent locations completely.
