I tried the android app. Say, I check the permissions of my facebook account by logging in, I didn't find a way (at least a conspicuous one) to logout. And, I didn't find the point of forcing me to create a mypermissions account if I am allowed to login and use the app without me confirming my account via the confirmation mail. I might as well create an account using a fake or someone else's email.
