Terms of publishing exports from dbdiagram

Hey everybody,

I created a DB diagram using dbdiagram.io and exported it to images. I did that to display my database scheme in the documentation of my own software.

Now I’m wondering on what legal terms this is even allowed. Can I just publish exports from dbdiagram.io? What are the terms and conditions? Is there any documentation on this? Do have to put a specific license on the files?

Thanks in advance!
Best, J
