End-to-end encrypted messaging, calls and file sharing on a private server your firm controls — not a Big Tech platform, not a jurisdiction that can be forced to scan your messages.
No credit card to start · Dedicated instance available · Data hosted offshore
Talk like no one's watching.
Because no one is.
Sovereign, end-to-end encrypted — on a server you control.
The EU's "Chat Control" proposals push toward mandatory scanning of private messages — including on encrypted apps. For a law firm, a clinic or a newsroom, that's not a privacy nicety. It's client privilege, patient confidentiality and source protection on the line.
Each firm can run on a dedicated, offshore instance. No shared cloud, no third party holding the keys, no backdoor to hand over.
Built on the audited Matrix protocol (Olm/Megolm). We don't reinvent cryptography — we inherit years of independent security review.
Clean onboarding, no cryptic technical setup. Your team signs in with a simple username and password — no phone number required — and just starts talking.
One private, branded workspace for the whole firm — messages, calls and files, all under your control.
1:1 and group chats, encrypted by default. Files, images and documents shared securely inside every conversation.
Encrypted 1:1 and group calls that run on your own server — no data flowing through a third-party call provider.
Walk a client through a document or a case file with encrypted screen sharing built into every call.
Send contracts, scans, images and recordings knowing they're encrypted in transit and at rest on your instance.
Add and remove staff, manage access and keep the whole firm on one governed workspace — you're the admin.
Native mobile apps plus desktop and web. Your team communicates from anywhere, still fully encrypted.
Confidentiality isn't a feature we bolt on — it's the whole product.

No "unhackable" theatre — just honest, layered protection. Here's exactly what keeps your conversations yours.
Messages, calls and files are encrypted on your device. Not even we can read them — we don't hold the keys.
Run on a dedicated, offshore instance. No Big Tech cloud, no data mining, no third party to hand it over.
Sign up with a username — no phone, no SIM to swap, no personal number tying you to your account.
We collect as little as possible. What we don't have can't be leaked, sold, or handed over.
Built on Matrix (Olm/Megolm) — reviewed by independent security researchers, not a black box.
TLS everywhere, security headers, firewalling, automatic patching and backups. Security as a process.
We say "end-to-end encrypted, we can't read it, you control the server" — never "unhackable". Honesty is the point.
