Most consumers don't pay any attention to the permissions apps want( not neccessary require) before they download the app. The "free" games come at a cost, your privacy. The developers make their money through advertisements and selling your info that they collect via the app. I only have a handful of apps on my phone ( IHeart radio, a couple weather/radar apps, telemetry app, etc,) I manually turn off every permission. IHeart radio doesn't need access to my location. Same with Facebook, I've denied access to everything I don't think is any of their business. Camera, SD card, internal storage, location, camera, microphone, contacts. Unless you manually deny access the owners of the app are collecting the data on everywhere you go, everything you say, every picture you take, every website you visit, every person you contact.
