Call for Crowdfunding!

Dear Folks! Zerocat’s Chipflasher applies for FSF’s Respects-Your-Freedom (RYF) Certificate. Sources are tagged, a sample device has been shipped, a free-software compliant storefront has been proposed... Read the full story. Let’s get the Chipflasher onto the FSF Website!


Social Charta

We believe in the strength of an open society and we are convinced that privacy empowers civil courage, which is necessary to keep open societies vivid. Without privacy, a society won't have experimental rooms that encourage development. Therefore, we promote:

Zerocat Shop

Please check the Zerocat Shop in order to get an overview of our current products and services. Your purchase will empower us to keep going and to share our sources and knowledge with the world. Any profit will be reinvested in Zerocat Projects.

Note we chose as our sales platform. It fits best to our social charta and it is a free software project in our neighboorhood.

JavaScript Licenses

As we are applying for FSF’s RYF-Certificate, we verified that the Fairmondo platform indeed uses freely licensed JavaScript code. Here our short summary as of February 2018:

Fairmondo’s JavaScript is free software licensed under the GNU Affero General Public License, however webpages carry minified code, license tags are missing, and it is not easy to determine whether the distributed files are equivalent to the sources. Furthermore, the Fairmondo site draws in external scripts from and which seem to run under non-free licenses.

For these reasons, we recommend to use Fairmondo with all JavaScript files disabled – this will reduce functionality, but should still allow you to purchase your favorite items ;-)

On the long run, we hope that Fairmondo will fix these issues and that their focus on free software will be esteemed by all of their customers!
