Session | Send Messages, Not Metadata. | Private Messenger
Session is an end-to-end encrypted messenger that minimises sensitive metadata, designed and built for people who want absolute privacy and freedom from any form of surveillance. Talk to your friends or talk to the world. You decide. Groups let you talk to up to 100 friends at once, with the same encrypted protections as one-on-one chats.
