Set which apps know your location on iPhone
With Location Services, you can choose which location-based apps—for example, Reminders, Maps, Camera, and Wallet—can gather and use data indicating your location. Your approximate location is determined using available information from cellular network data, local Wi-Fi networks (if you have Wi-Fi turned on), and GPS (if available). The location data collected by Apple isn’t collected in a form that personally identifies you. When an app is using Location Services, 
appears in the status bar.
Turn on Location Services
If you didn’t turn on Location Services when you first set up iPhone, go to Settings 
> Privacy > Location Services, then turn on Location Services.
Turn off Location Services
Go to Settings > Privacy > Location Services, then choose from the options to turn off Location Services for some apps and services, or for all of them.
If you turn off Location Services, you’re asked to turn it on again the next time an app or service tries to use it.
Review the terms and privacy policy for each third-party app to understand how it uses the data it’s requesting. See the Apple Support article About privacy and Location Services.
Change Location Services settings for system services
Several system services, such as location-based suggestions and location-based ads, use Location Services.
To see the status for each service, to turn Location Services on or off for each service, or to show in the status bar when enabled system services use your location, go to Settings > Privacy > Location Services > System Services.
Delete significant locations
The Maps app keeps track of the places you’ve recently visited, as well as when and how often you visited them. Maps uses this information to provide you with personalized services like predictive traffic routing. You can delete this information.
Go to Settings
> Privacy > Location Services > System Services > Significant Locations.Do one of the following:
Delete a single location: Tap the location, tap Edit, then tap
.Delete all locations: Tap Clear History. If you’re signed in to iCloud, this clears all your significant locations on any devices that are signed in with the same Apple ID.
