About

Session is an end-to-end encrypted messenger that minimizes sensitive metadata, designed and built for people who want absolute privacy and freedom from any form of surveillance. Session accounts are completely anonymous. No phone number or email required. Session doesn’t collect data, so there’s nothing to leak. Send messages through our onion routing network and leave no trace. Session’s code has nothing to hide. Anyone can view, audit, and contribute. With no central point of failure, it’s harder to shut Session down. Talk to your friends or talk to the world. You decide. Closed groups let you talk to up to 20 friends at once, with the same encrypted protection as one-on-one chats. Got a bigger crowd? Use an open group to connect with as many people as you want. Sometimes, a text just isn’t enough. Voice messages let you send something a little more personal, so nothing gets lost in translation.

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.
