Wondering how the mechanism works, the app will take a sneak-peak into your friends list and thereupon save some vital information which would then help it to compare the previous data the next time you login. If the numbers don’t turn out to be the same on tallying up, the app will then tell you who has ‘unfriended’ you and who has done the otherwise by deactivating their account.
