FWIW, on iOS, the you're asked for each app that wants access to location services. Further, you can turn this off globally for all apps, or individually for apps in the Settings app. Even further, you can lock down the settings app with a passcode required to make changes. So, parents can lock down the settings for location services so that their kids... (whom I assume just say "yes" when running an app that asks for access to it) can't leak their location.
