About
Privacy and security as first principles.
ArcanTx is a technology company building secure, privacy-first communications software and providing specialized software engineering and consulting.
The name joins arcanum, the secret, with Tx, transmit. Our work starts from one premise: a system should be unable to betray the people who rely on it, because it was never built to know their secrets.
We favor small, auditable designs, clear threat models and software that does exactly what it says.
