Šepot — end-to-end encrypted messenger
Initial public release. Anonymous on-device identity (no phone number, e-mail, or password), Signal-protocol cryptography (X3DH + PQXDH, Double Ratchet, sealed sender) via libsignal, a metadata-minimizing relay, group chats, disappearing messages, encrypted local storage, optional Tor transport, and a UI localized into Czech, English, German, Russian, and Italian. Monorepo: Flutter client (app/), Rust relay + wire types (rust/), protobuf definitions (proto/), self-host deploy (deploy/). Licensed under AGPL-3.0 with an app-store distribution exception (§7).
