For what it is worth, a lot of apps track location and show it to others unless you turn it off. Snapchat is another popular app that will show your location to others unless you turn it off. If you haven't and you are concerned about your location whereabouts being public, check your apps and also what has the right to use "location services". Most can be turned on/off within the app, but just be aware there are many common apps people don't think of (messaging, posting apps, travel apps, etc.) that also show location.
