Hello Moise,
We would very much like to have a French version of CODAP! As you have probably noticed we have translations for several languages. Unfortunately, though, we do not have a funding source for translations. All these translations were done by volunteers. The good news is that creating a new translation is a bit tedious, but not technically difficult. We use a cloud-based translation service called Po Editor (https://poeditor.com) to localize all the CODAP. The tool is pretty easy to use and work can be done from anywhere. If you would be able to find a volunteer or team of volunteers we would be able to get you set up with accounts on the Po Editor pretty quickly.
If this is of interest to you, please do let us know. We would be happy to help get you started, and to support you through the process.
