Ricochet – Anonymous Instant Messaging for Real Privacy
https://ricochet.im/

Ricochet is a different approach to instant messaging that doesn’t trust anyone in protecting your privacy. Features include: a) Eliminate metadata. Nobody knows who you are, who you talk to, or what you say; b) Stay anonymous. Share what you want, without sharing your identity and location; c) Nobody in the middle. There are no servers to monitor, censor, or hack; and d) Safe by default. Security isn’t secure until it’s automatic and easy to use. This will be added to Privacy Resources Subject Tracer™.
