Cat that kicks an exclamation mark.
The Zerocat Label
True Free-Design Hardware. Transparent. No Tricks.

Team: Zerocat and Friends

The Zerocat Label is run by Kai Mertens, who is supported by friends and pioneer customers.

For any question or feedback, feel free to get in touch with any active fellow as listed below. You can reach us via encrypted chat or encrypted email, all processed on zerocat machines. Our capabilities to respond in time vary, but you should be able to meet us at least once per week during our Jour Fixe:

Monday Morning 11h a.m. Europe/Berlin local time

If you need to see a tool come true, which does not yet exist as free-design hardware, we would love to hear about it!

Want to join the team and support Zerocat? Get in touch, but please be aware that we expect you to be a reliable team member, carrying our philosophy to heart.

We are using the GNU Privacy Guard in conjunction with email:

The GNU Privacy Guard is a complete implementation of the OpenPGP standard. It is used to encrypt and sign data and communication. [...] — GNU Guix Package Description

Our public PGP keys are available for download from this site (see PGP-Key), as well as from hkp://

We are using the Jami Communication Software:

Jami is a secure and distributed voice, video and chat communication platform that requires no centralized server and leaves the power of privacy in the hands of the user. It supports the SIP and IAX protocols, as well as decentralized calling using P2P-DHT. — GNU Guix Package Description

To sum up: If you want to do things in difference to the main stream, there are secure ways to do it! Spread the word, tell people about us and engage a free-design hardware hacker!
