Private communication, built to know as little as possible

TACENZA is made by CARTIQO for privacy-minded people and communities, starting in Denmark and the EU. People who want the groups and chats they know – without a platform that reads them.

TACENZA. is a CARTIQO. product. Its apps make no requests to anyone else: no analytics, no fonts or scripts from third parties.

What we believe

  1. The server stays blind. A feature that would teach the server something new is opt-in, explained where you switch it on, and reversible.
  2. Say what happens. Every setting and every destructive action states its consequence in plain words, and every action gives feedback.
  3. Everyday first. Chatting and communities must feel as quick and familiar as mainstream apps. The security never gets in the way.
  4. Honest limits. When something can’t be done privately, we say so instead of faking it.
  5. Two languages, equal quality. The apps work in English and Danish, and Danish is never an afterthought.

Where TACENZA is today

  • TACENZA Chat

    Working towards 1.0: an installable web app, a Windows desktop app and our own backend. Usernames can be claimed now.

  • TACENZA Mail

    In development. The first parts are built – shared addresses, encryption, team settings – and sign-up opens when it’s ready.

  • Before 1.0

    A security review of Chat is planned before 1.0, and forward secrecy after it. Until then, the known limits are written down.
