P2P · End-to-end encrypted · Android

Encrypted.
Peer‑to‑peer.
Yours.

Voyd is a P2P-first encrypted messenger. Messages, calls, and files flow directly between devices over WebRTC — no relay reads them, no server stores them. Your keys never leave the device.

What you get

Built for people who don't want to trust a server.

01E2E

End-to-end encrypted

Per-message forward secrecy via Double Ratchet. AES-256-GCM bulk. ECDSA-signed envelopes. Audited primitives only.

02P2P

Peer-to-peer first

Direct WebRTC DTLS between devices. Signaling and relay only carry blobs they can't decrypt. Falls back gracefully behind NAT.

03PQ

Post-quantum hybrid

ML-KEM-768 layered with classical ECDH so today's traffic stays safe even if quantum hardware lands tomorrow.

04Yours

Recoverable, not custodial

Hardware passkey recovery via WebAuthn. No central key escrow. Lose your device, keep your identity.

Cryptography

Open primitives. Zero trust required.
