Project calls itself Open Source, but I can't seem find the license.
Does it have one?
That's what I was wondering too, I have sent them an email.
Update: It's BSD 2-Clause. This will be added to the repo soon. Also the people behind it are super helpful and passionate behind the project!!
further update: The license is there now[0].
