Post-quantum encrypted communications · iOS 26+

Q-Day is coming.
We are ready now.

Adversaries are already recording encrypted traffic. They will read it the day a working quantum computer goes live. Qlavis encrypts and signs messages, calls, files, and in-chat payments with cryptography that holds after that day.

The encryption you use today
has an expiry date.

2024

NIST ratified the post-quantum encryption standard, FIPS 203.

Now

Qlavis encrypts every message, call and payment with post-quantum cryptography.

2030

Post-quantum encryption becomes mandatory on US national-security systems.

2033

Classical encryption is retired across US national-security systems.

Q-Day

A working quantum computer. Traffic recorded years earlier becomes readable.

01 Everything

Post-quantum sealed. Not just your texts.

Every layer of the conversation is sealed post-quantum, at NIST Level 5, the highest security category that exists. Nothing falls back.

  • Avatar · post-quantum
  • Text · post-quantum
  • Voice note · post-quantum
Qlavis chat, an encrypted conversation with in-chat USDC, RLUSD and XLM payments
  • Calls · post-quantum
  • Crypto transfer · post-quantum
  • Files · post-quantum

Files · voice notes · your profile photo, post-quantum too. No exceptions.

02 Identity
Qlavis recovery phrase, your Qlavis Identity is twenty-four words, bound to your device

No phone number. No email. Just twenty-four words.

Your Qlavis Identity is twenty-four words, held only on your device. Lose them and even Qlavis can’t bring them back. That is the point: no one can.

03 Calls

Even your calls can’t be cracked.

Qlavis protects every voice and video call with the same future-proof encryption as your texts, no weak link.

If a call can’t be sealed post-quantum, it doesn’t connect.

Qlavis encrypted video call, end-to-end and post-quantum on every audio and video call
04 Crypto in chats

Send crypto without leaving the chat.

A transfer rides inside the conversation, sealed post-quantum like any other message. The same recovery phrase is also your self-custodial wallet, your keys, yours alone.

Self-custodial · USDC · XLM · XRP · RLUSD

Qlavis chat, sending USDC and RLUSD inside the encrypted conversation Qlavis self-custodial wallet, balances in USDC, XLM, RLUSD and XRP, from the same recovery phrase
05 Rooms

Groups, sealed like everything else.

Create a room, add people by @handle, set who can post. Every message, photo and voice note inside carries the same post-quantum protection as your one-to-one chats.

Roles · Invitation only · Room Seal

Qlavis room, a private group chat with roles, end-to-end and post-quantum encrypted
06 The server

We can’t read it. No one can.

Our servers hold nothing you said zero plaintext, verifiable
Your contact list never leaves your phone no address book on our servers
Delivered messages are erased from the server 14-day ceiling on the rest
Notifications never carry your words decrypted on device only
07 Closer threats

Not every adversary has a quantum computer.

Some are as close as a stolen phone or a glance over your shoulder.

Qlavis ScreenScreenshots and screen recordings come back black, in chats and on calls.
Hidden IPFlip it on, the person you call never sees your IP.
Local-firstYour history lives on your device, not our cloud.
