Privacy-centered instant messaging.

At whistle.im we believe that privacy is not a matter of having something to hide but one of our most fundamental rights. Whether you are communicating business secrets with your partners, unveiling a dark secret to the press, talking dirty to your boy- or girlfriend or just joking with your friends, you shouldn't have to worry about governments or companies spying on you for whatever reason they made up for themselves.
