I denied FaceApp access to my photo library and all apps are denied access to “Background refresh”. I didn’t post pictures directly to any social media. So exactly what does FaceApp have access to besides a few selfies? I was more interested in seeing how good the machine learning was than anything else. It was pretty good, it recognized different angles, it didn’t try to put glasses on my face when I was already wearing glasses and didn’t try to add a beard when it saw I had one.
