Whisper is a decentralized, dual-transport messaging protocol. Connect directly to peers over local Wi-Fi and Bluetooth, or tunnel securely through our zero-knowledge internet relay. No phone numbers, no central databases, total forward secrecy.
Every single message you send is encrypted with a unique, one-time key using the Double Ratchet Algorithm. Even if a future key is compromised, your past conversations remain mathematically unbreakable.
Automatically discovers peers via local Wi-Fi Direct and BLE. If physical proximity is lost, it seamlessly falls back to our secure internet WebSocket relay.
No phone numbers required. Your identity is a mathematically verifiable Ed25519 public key. Handshakes are authenticated cryptographically to prevent man-in-the-middle attacks.
In an emergency, Whisper allows you to shred specific conversations, wipe all contacts, or trigger a complete factory reset that overwrites the SQLCipher database with random bytes.
Data at rest is just as important as data in transit. Whisper utilizes a customized SQLCipher implementation to ensure all stored messages are encrypted on your local hardware.
Assign custom retention policies per contact. Set messages to automatically purge after 24 hours, 7 days, or immediately upon reading to leave no trace.
The Magus Labs relay server operates strictly in RAM. It only forwards encrypted binary blobs and retains zero logs. We cannot see who you talk to or what you say.
