License Issue for studying

Hi everyone!
I wanna ask about the license of using GoJS
Is it legal if i use GoJS for studying?
For more details, I use GoJS for making a demo project for graduating from a university. That is non-commercial project.
So, Is it the Evaluation License Agreement? I feel a little confused with “evaluation purposes”.

If you want to use GoJS for an academic project at a university or school, you can get a free license. Contact sales for more information.

However, you will not be able to ask for technical help – not by email and not in this forum – unless you purchase support.
