Product showcase: Session, a messenger without phone numbers or metadata

Session is an open-source, decentralized messaging application that emphasizes privacy and metadata minimization through end-to-end encryption, onion routing, and a network of incentivized relay nodes. The document outlines account creation without personal identifiers, mnemonic-based account recovery, support for disappearing messages, and options for users to self-host infrastructure for larger features; it is a product-focused description rather than a report of a cyber incident.
