As the page doesn't make the licence immediately clear: this is not Free software.
From the licence text on GitHub [0]:
> 1.1 AnyGrids is provided free of charge and may be used by you for any legal purpose. Despite no charge for the product, there are a number of conditions for using this tool.
That's a step in the right direction, but it's still not Free software. Section 2.3 clearly breaches Freedom 1. [0]
If you're serious about this project and want it to be adopted by Free / Open Source software projects, you should use a standard Free and Open Source software licence like the GPL or the MIT licence. It's a bad idea to roll your own non-standard licence, even if its terms are reasonable, and even if it meets the requirements for qualifying as a Free Software licence and an Open Source licence.
