LICENSE file or license information for this project?

From the website, dizzy.ai, there is text that says:

Both hardware and firmware is open-source, you can easily tweak the code for your needs. Your contributions are welcome!

But I see no license file on the schematics or source code. Was it the intent to make source code for this project free/libre/open source as well as putting the other digital artifacts under a free/libre license?

If so, could you provide license information, preferably under a LICENSE file? If not, please remove the indication that it is open source as without a free/libre license, this project would not be open source by the commonly accepted definition.
