Privacy Preserving Infrastructure
Existing secure messengers provide end to end encryption so that eavesdroppers can't see the contents of the communication. But these centralized platforms, much like a post office, act as clearing houses for messages.
They need access to metadata about your activities such as who you talk to, when and how much in order to offer features like group messaging and offline delivery.
Communications metadata us 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. These systems have grave consequences for freedom, autonomy and sometimes...even life itself.
Cwtch is a metadata resistant privacy platform designed to hide this metadata and help you resist surveillance.
Like other systems, Cwtch uses end to end encryption. but the journey its messages take is different. Cwtch is a decentralized peer to peer platform built on Tor onion services. With no need for a centralized server to route messages through, and onion routing provided by Tor, Cwtch establishes direct connections between peers while minimizing and sometimes even eliminating the metadata that 3rd parties can see.
Cwtch uses cryptographic identifiers that anyone can anonymously generate for themselves as many times as they want. This means they can't be tied to your real world identity by anyone but you.
Cwtch is designed to put consent first. This means we never want the app to do something you don't expect or want. Cwtch gives more control over what information is shared, how and who can communicate with who. We'll never included unsolicited content such as advertising or trends.
Cwtch is designed for people who need to protect, not only the *content* of their communication, but *who* they are talking to as well. Cwtch provides a safe space for you and your friends, family, comrades, and fellow rabble-rousers.
