About dunno
DUNNO is a private messenger built for people who value their privacy. Every message, voice recording, and file is end-to-end encrypted and sent over the Tor network. There is no central server — your data stays on your device.
Chat securely Send text messages, voice messages, photos, and files. All communication is encrypted with your contact's public key and routed through Tor. Your IP address stays hidden.
Walkie-talkie (PTT) over Tor Hold to talk. Your voice is encrypted and streamed over Tor for maximum privacy. Release to listen. Perfect for quick, private conversations.
Fast Call (WebRTC) Higher quality audio calls with end-to-end encryption (DTLS-SRTP). Signaling stays on Tor. Your call audio remains private.
No accounts, no servers DUNNO doesn't need your phone number, email, or any personal information. Contacts are added by scanning a QR code — you control who can reach you.
Privacy by design • End-to-end encryption for everything • No telemetry, no crash reports, no tracking • Encrypted database (SQLCipher + Android Keystore) • No cloud backups — full encrypted backup/restore available • App lock with device PIN or fingerprint • Block unwanted contacts • Open source
DUNNO is built for anyone who wants to communicate without being watched. No accounts, no servers, no compromise.
