Send Messages, Not Metadata.·getsession.org
Session is a cross-platform, end-to-end encrypted messaging app designed for secure, private, and anonymous communication. It routes messages through an onion-routing network to remove metadata collection and does not require a phone number or email to sign up. The app is built on a decentralized, web3-powered Session Network with decentralized message storage and self-managed encryption keys. It supports group and community chats, disappearing messages, and file attachments.
