The NSA has been under a lot of fire for tracking everyone for some time now. We do not know which part of any story is true. But, in the world of modern Internet, it is safe to tell there is no such thing as privacy.
BitTorrent has announced BitTorrent Chat which is in Private Alpha stage. Meaning, you’d have to sign up and get an invite from them. They claim that the messages will not be stored in any server and will move through peer-to-peer encrypted network. Also, it’ll be free for all.
As of now, there are not much details. But, you can sign up for the Private Alpha here.
