Berty makes privacy the easy option. Berty is an encrypted and offline peer-to-peer messenger with NO central server. Connect with or without an internet connection, message for free, and avoid surveillance and censorship. DISCLAIMER: Berty is fresh off the development line and hasn’t been audited yet. Please keep this in mind when exchanging data. END-TO-END ENCRYPTED MESSAGING In some countries, even a lol or a like can get you sent to jail. Berty is end-to-end encrypted - not even our developers could access your data, let alone corporations or governments. 100% DECENTRALIZED Just like blockchain technologies, Berty doesn’t pass your data through central servers - the place where internet service providers, hackers, and governments can intercept your data. Instead, Berty’s network is distributed, based on P2P direct messaging. COMPLETELY ANONYMOUS Berty couldn’t care less about who you are. You don’t need to provide your real name, an email, or a date of birth. You don’t even need a SIM card! PROTECT YOUR METADATA You might not know what metadata is, but WhatsApp, Facebook Messenger, and WeChat all collect it. This data can reveal a lot about you - so you’ll be glad to hear Berty is a messaging app alternative that collects as little metadata as humanly possible. COMMUNICATE WITHOUT TRADITIONAL NETWORKS Berty is made to work in the most challenging network conditions in the solar system. If governments, hackers, or natural disasters shut down cellular or internet networks, users can still make vital instant communications over Berty’s proximity Bluetooth feature. JOIN GROUP CHATS Berty is a full-featured instant messaging app. Create groups, chat securely, and share media with friends, family, and colleagues. SHARE VOICE MESSAGES Instantly send encrypted voice memos and audio files on Berty’s decentralized network. FREE FOREVER Privacy is a right for everyone, so Berty doesn’t profit from keeping you safe online. Created by an NGO, Berty will always be free and relies on the generous community to fuel development. TOGGLE BETWEEN ACCOUNTS Create different accounts to split your messaging identities by work, school, family - however, you want to categorize your messages! The Berty messaging app, built on the Berty Protocol, is designed, developed, and deployed by the French non-profit NGO, Berty Technologies. But Berty isn’t just decentralized in terms of its architecture - it’s also owned by the community, not a corporation interested in profits. The progress of Berty relies on developers testing and feeding back on our open source code, generous funding from funds and individual donors, and online and offline advocacy in the community.
