The top three permissions requested by iPhone apps globally are for photos, camera access, and location while using the app. But 40% of the top 1,500 apps in the U.S. ask for background location permissions that can allow them to track your every move, and that jumps to 51% in China.
Another quarter of top apps typically ask to access your contacts and also ask for Bluetooth permissions, which can be used to determine location.
Less than 1% ask for HomeKit integration so you can ask Siri to turn out the lights.
And NFC and GameKit, Apple’s social gaming service, get almost no pick-up in the top 1,500 apps in any country.
