Berty Messenger is an encrypted and offline peer-to-peer messaging app that prioritizes privacy. With no central server, users can connect with or without an internet connection, ensuring free messaging while avoiding surveillance and censorship. End-to-end encryption secures all communications, making it impossible for anyone, including developers, corporations, or governments, to access user data. Berty operates on a decentralized network, akin to blockchain technology, ensuring data privacy by bypassing central servers where interception is possible.

In addition to its strong privacy features, Berty Messenger allows users to communicate without traditional networks, making it ideal for challenging network conditions. Users can create group chats, share media securely, send encrypted voice messages, and toggle between different accounts for varied messaging identities. Developed by the French non-profit NGO, Berty Technologies, this messaging app remains free, community-owned, and open source, emphasizing user privacy and security above all else.
