Location Services
Location Services lets apps such as Reminders, Maps, Camera, and third-party location-based apps
gather and use data showing your location. The location data collected by Apple isn’t collected

networks (if you have Wi-Fi turned on). To conserve battery life, turn location services o when
you’re not using it.
When an app is using Location Services, appears in the status bar.
Every app and system service that uses Location Services appears in the Location Services settings
screen, showing whether Location Services is turned on or o for that app or service. If you don’t
want to use Location Services, you can turn it o for some or for all apps and services. If you turn
Location Services o, you’re prompted to turn it on again the next time an app or service tries to
use it.
The location data collected by Apple doesn’t personally identify you. If you have third-party apps
on iPod touch that use Location Services, review the third party’s terms and privacy policy for
each app to understand how it uses your location data.
