French research institute Inria has released a small portion of the source code that is going to power France’s contact-tracing app StopCovid. It is available on several GitLab repositories under the Mozilla Public License 2.0. While the French government announced that everything would be open source, it’s going to bit more complicated than that.

As Inria wrote in the announcement, the project is now divided in three parts. Critical elements of the infrastructure are not going to be available on the GitLab repositories. Instead, Inria will only release documentation on the security implementations, as ANSSI and France’s data protection watchdog CNIL recommended some level of transparency on this front.
