Cwtch is decentralized and focused on metadata-privacy in addition to communications privacy. Unlike other communication platforms, none of your messages are routed through a centralized server that has access to metadata such as your social network of friends, or who sent and received a particular message. Even in experimental group chats which do rely on a routing server, the server learns no information about which messages belong to which group, who is a member of which group, or who messages are intended for. We believe that our tools should help people resist surveillance. Communications metadata is known to be exploited by many adversaries to undermine the security of systems; to track people; and to conduct large scale social networking analysis that feeds into mass surveillance systems. And because of that, we explicitly designed Cwtch for metadata privacy.
