Qlavis is a messenger where everything is sealed with post-quantum cryptography: messages, voice and video calls, photos, videos, documents, and profile photos. Your identity too: it carries a post-quantum signature of its own. End-to-end encrypted from the first minute, with nothing to configure. No phone number, no email. Your identity is created on your iPhone as a 24-word recovery phrase that only you hold. Nothing to verify, nothing to register. Your keys never leave the device, protected by the Secure Enclave, so nobody, not even Qlavis, can read your messages or pass themselves off as you. Built for the quantum era Behind every conversation stands the complete NSA CNSA 2.0 algorithm suite: ML-KEM-1024 key encapsulation, AES-256-GCM encryption, ML-DSA-87 signatures, and SHA-512 key derivation. Key encapsulation and signatures both run at NIST security Level 5, the highest category defined, so what you say today stays unreadable to the computers of tomorrow. A signature instead of a promise The signature on your identity is ML-DSA-87. The other side checks it on their own device rather than taking the server's word, so no future computer can pass itself off as you or forge who said what. Calls, not just messages Audio and video run on the same post-quantum keys as your chats. A call that cannot establish them does not connect: that is a condition, not an option. If you wish, turn on relay mode and the other side never sees your IP address. Rooms for your people Create a room, add members by @handle, hand out roles and decide who can post. Text, photos, videos and voice messages in a room are encrypted the same way as in one-to-one chats. Every membership change is signed and verified on each member's device, the room's name and photo are encrypted too, and the only way in is an invitation: there are no public links. The Room Seal, a short code every device computes on its own, lets members confirm they all see the same room. A server that sees nothing Our server is a blind relay: it stores no message content, cannot decrypt a single byte, and deletes encrypted envelopes the moment they are delivered. What we never hold can never be leaked, sold, or handed over. Everything you expect • Text, voice messages, photos, videos, and documents • Read receipts and delivery status • Encrypted profile photos • App lock with Face ID • Qlavis Screen: screen-recording and screenshot protection for your chats • All local data encrypted at rest on your device An optional wallet Crypto, right in the chat: send XLM, USDC, XRP, or RLUSD inside a conversation, encrypted like any other message. Keys are generated on your device, never leave it, and belong to you alone. Qlavis never holds funds, has no access to them, and charges no fees. An open protocol The full protocol specification is published at qlavis.app/architecture.html. The protocol design, rooms included, has passed formal verification, and the server's behavior is tested continuously in production.
