I'm using Facebook on iOS 7. When I send a message, my location is included, and the prompt tells me how to turn it off permanently: Go to Settings > Privacy > Location Services and turn it off for Facebook. But Facebook doesn't appear as an app in Location Services. So, how do I prevent Facebook from accessing my location?
To be clear, the question is not about whether Facebook includes my location in messages. It's that I don't trust Facebook itself to access my location.
