Tunnel — Private Messaging by Design

Tunnel is a secure messaging app for people who care about privacy. Every conversation is end-to-end encrypted, every account is protected by a cryptographic identity you control, and there is no phone number or email required to sign up.

WHAT MAKES TUNNEL DIFFERENT • End-to-end encryption on every message, photo, file, and call — Tunnel servers never see your plaintext content. • Quantum-safe key exchange — modern Curve25519 cryptography combined with post-quantum CRYSTALS-Kyber to protect your conversations against current and future attacks. • No phone number, no email — sign up with just a username. Your identity is a key pair generated locally on your device. • Move between devices with a single credential — no SMS codes, no recovery emails, no third parties. • Voice and video calls, encrypted end-to-end, with native CallKit integration on iPhone. • Per-conversation safety codes you can verify in person. • Forward secrecy via the Double Ratchet protocol — past messages stay safe even if a future key is compromised.

CONVERSATIONS YOU CONTROL • Your contact list lives only on your device. • Add contacts by username, by scanning a QR code, or by pasting an invite link. • Block and unblock anyone without notifying them. • Mute conversations, archive threads, star messages. • Send photos, videos, and files — no plaintext ever leaves your device. • Edit and forward messages, reply to specific messages, react with emoji. • Disappearing-message timers per chat.

PRIVACY-FIRST IDENTITY • Your account is a cryptographic credential you generate locally and save yourself. • Tunnel does not store your credential — the server only sees a one-way hash that cannot be reversed. • Multi-device support — import your credential on a new device, and each device gets its own per-device encryption keys.
