One floor. Every life.

The same maximum cryptography will protect a parent, a newsroom, a company, and a research lab.

ML-KEM-1024 + X25519 The floor is universal

01 / THE DOORS — SIX WAYS IN

Walk in through your own door.

Individuals Post-quantum privacy you would want for your family, on by default. Journalists Protect the source, the story, and yourself. Business Keep the company's conversations the company's. Government & Defense Evaluator-ready evidence and CNSA 2.0-aligned primitives. Developers Build on the core beneath QERYX. Compare QERYX beside classical E2E, category by category.

Read the theorem the whole product obeys

A conversation is exactly as secure as its weakest end. That is a theorem, and QERYX is built to obey it:

security(session) = min( security(you), security(them) )

No one can buy their way past the person on the other end. So the floor is maximal for everyone: hybrid ML-KEM-1024 + X25519 key agreement, ML-DSA-87 identity signatures, and a fresh Q-Ratchet key for every message — for every seeker.

03 / THE HARD QUESTIONS

Ask the question that decides it.

Which door do I pick if I am several of these at once?

Any of them. The doors change the story, never the instrument — the same app, the same keys, the same floor. Pick the page that sounds like your day and read the others when you are curious.

The floor will be yours.

Every instrument carries the same maximum crypto. Choose tools, not safety.
