A few weeks ago, the world went crazy when reports surfaced that Facebook Messenger was snooping on you. Reporters, hackers, and users alleged that, because Messenger had the permission to use your camera, monitor your location, or (on Android) read your text messages, that it was doing so all the time. The scare was eventually debunked. The consensus: just because an app has the ability to do something doesn’t mean it’s doing it 24/7. You can find these same permissions, from the camera access, to the location-tracking, to the text-message reading in many social networking and texting apps, partly because Android and iOS don’t allow much control when it comes to asking users for their permission to do things. All developers can ask is “Do you want tracking on or off?” with no shades of gray in between. No more. With iOS 8, Apple now provides three options for location-tracking permissions: “Always,” “Never,” and “While using the app.”
