The Cloaq app is an anonymous social app that wants to differentiate itself and be even more secretive. It is doing so by not requiring any personal information from you like your email or phone number to sign up. The idea is that if the app was hacked, there would be no personal information for the hacker to gain.
The Cloaq app just uses a password and each user gets assigned an @id number. The numbers will start at @alpha1 and it will be through until it hits @alpha999, when it does it will start @beta1 and so on. Rumor has it that the company is only letting the first 500 users into the @alpha batch. They want to make the Cloaq app more exclusive by offering it to a small batch for the launch.
