About
Cwtch (/kʊtʃ/ - a Welsh word roughly translating to “a hug that creates a safe place”) is a decentralized, privacy-preserving, multi-party messaging protocol that can be used to build metadata resistant applications.
Decentralized and Open Participants in Cwtch can host their own safe spaces, or lend their infrastructure to others seeking a safe space. There is no “Cwtch service” or “Cwtch network”. The Cwtch protocol is open, and anyone is free to build bots, services and user interfaces and integrate and interact with Cwtch.
All communication in Cwtch is end-to-end encrypted and takes place over Tor v3 onion services.
Cwtch has been designed such that no information is exchanged or available to anyone without their explicit consent, including on-the-wire messages and protocol metadata.

About
The first messenger without user IDs.
Other apps have user IDs: Signal, Matrix, Session, Briar, Jami, Cwtch, etc. SimpleX does not, not even random numbers. This radically improves your privacy.
Many users asked: if SimpleX has no user identifiers, how can it know where to deliver messages?
To deliver mesages, instead of user IDs used by all other platforms, SimpleX uses temporary anonymous pairwise identifiers of message queues, separate for each of your connections — there are no long term identifiers.
You define which server(s) to use to receive the messages, your contacts — the servers you use to send the messages to them. Every conversation is likely to use two different servers.
This design prevents leaking any users' metadata on the application level. To further improve privacy and protect your IP address you can connect to messaging servers via Tor.
Only client devices store user profiles, contacts and groups; the messages are sent with 2-layer e2e encryption.
