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.

Qlavis utilizes post-quantum cryptography, specifically the NSA CNSA 2.0 algorithm suite, including ML-KEM-1024 and ML-DSA-87. This ensures messages remain unreadable even to future quantum computers, offering a higher security level than traditional encryption methods. ### How is user identity managed in Qlavis? User identity is established via a 24-word recovery phrase generated on the iPhone, which is held solely by the user. This phrase is protected by the Secure Enclave, preventing anyone, including Qlavis, from accessing or impersonating users. ### Can I make voice and video calls with Qlavis? Yes, Qlavis supports encrypted audio and video calls that use the same post-quantum keys as your chats. Calls will not connect if these keys cannot be established, ensuring a secure communication channel. ### How does Qlavis handle group communication? Qlavis allows users to create secure rooms where members can be added by @handle. Text, photos, videos, and voice messages within rooms are encrypted using the same robust post-quantum methods as one-to-one chats. ### Does Qlavis have ads? No, Qlavis is ad-free. The application is completely free to use and does not display advertisements to its users. ### What devices is Qlavis available on? Currently, Qlavis is available for iPhone devices. The application is designed to leverage the security features of iOS. ### How often is Qlavis updated? Qlavis was last updated on September 7, 2026, with version 1.0.4. This indicates a recent focus on development and maintenance of the application. ### What is the age rating for Qlavis? Qlavis has an age rating of 17+. This is likely due to the advanced cryptographic features and the potential for sensitive communication facilitated by the app. ## Version history (last 4 releases) ### 1.0.4 — 2026-09-07 ROOMS The owner can now delete a room for everyone: the room and its history disappear on every member's device, including devices that were closed at the time. If the owner deletes their account, their rooms are deleted for everyone the same way. Every action in Room Info now shows its result at the top of the page: what changed, or the exact reason it was refused. A member who deleted their account and registered again under the same name can be added back and receives messages on every device. ACCOUNT DELETION When a contact deletes their account, your device now verifies their own signed confirmation and retires their old keys by itself. No prompt, no button to trust. INVITE A FRIEND Your invitation link is now one tap away: at the end of setup, in the empty chat list, and when a name you search for is not on Qlavis yet. FIXES A room deleted for everyone no longer leaves an empty one-to-one chat behind on a device that was closed at the time. Privacy settings never appear as messages in rooms. Registering again on the same phone no longer drops your contacts' verified keys at the next launch, and sending in a room recovers them on its own. Security notices stay below the chat header, and Room Info fits the screen on every model. ### 1.0.3 — 2026-09-05 POST-QUANTUM VERIFICATION ON FIRST OPEN A contact's post-quantum identity (ML-DSA-87) is now anchored the moment you open the chat, no matter who wrote first or whether the app was closed when the first message arrived. The Safety Number screen reflects it right away, and in-chat wallet payments to that contact verify as expected. ROOMS A member added while everyone else was offline is trusted and readable on every device as soon as it comes back, and their messages reach everyone. A new member sees the room from the moment they were added; the full membership history stays under Security. Membership events no longer count as unread. The Room Seal moved to SHA-512: devices on this version compute the same code, older versions show a different one until they update. ### 1.0.2 — 2026-09-03 ROOMS: GROUP CHATS, SEALED LIKE EVERYTHING ELSE Create a room, add members by @handle, set roles and who can post. Text, photos, videos and voice messages in rooms are end-to-end encrypted with the same post-quantum protection as your one-to-one chats: ML-KEM-1024, AES-256-GCM and ML-DSA-87 signatures. Membership changes are signed and verified on every device. Room names and photos are encrypted too, and they catch up on their own if you were offline when they changed. Room messages that arrive while the app is closed show up in notifications with the room name and are waiting for you when you open the app. FASTER, CLEARER MEDIA Sending shows what is happening: Compressing, then Uploading, with a percentage. Large videos are prepared in the background without the camera photo stalling. Playing a video for the first time shows Downloading with a percentage and no longer freezes the screen. Videos play with sound as expected. On cellular, photos are sent in a lighter size; Original quality stays exactly as you set it. STABILITY Sending large files from the camera no longer runs the app out of memory. Send again on a failed attachment always does something: it retries or tells you what to do. The Calls tab no longer gets stuck loading after restoring your identity. The app reconnects cleanly after a long time in the background. ### 1.0.1 — 2026-09-01 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
