Quantum-safe, today.

End-to-end encrypted with MLS (RFC 9420) and SaQura's post-quantum suite (Gen8). Secure — even against tomorrow's computers.

No account. No number. No trail.

Your identity is created on your device and never leaves it. No one finds you through a phone number or email.

Voice & video callsSoon

Quantum-safe voice and video chat, with no phone number.

Sovereign, on your infrastructure.

Self-hostable from day one. The server only relays ciphertext — content stays with you.

Whoever listens in, wins. Let no one listen in.

Metadata — who talks to whom, when and how often — often reveals more than the content itself. SaQura works without an account, phone number or address book, so it never piles up.
The BSI recommends phasing out classic-only encryption by 2030/2031 — SaQura is quantum-safe today.
Compliance under scrutiny (GDPR · BSI · NIS2) — built to these requirements, deployable in-house.

For agencies & emergency services

One chat. Split by the situation.

In an operation you reach specific sub-areas — “All”, “Command”, “Patrol 1” — each encrypted on its own. Release instead of forward, forensically traceable.

For organizations & agencies

Self-hosting and central management.

Run SaQura on your own infrastructure — the server only relays ciphertext and never sees content. Control features by per-organization policy, manage seats and licenses, and roll the app out through your device management (MDM). Self-operated or hosted by KyotoTech — your choice.
