Looking at the website, I'm at work on OSX, so can't download... but it's unclear if this is free, open-source or commercial software... the marketing of this page/site is pretty hard to tell, and hideous overall.
If it's commercial the lack of any pricing or licensing information leads me to want to avoid at all costs... I'm assuming it's a commercial product, and it's completely not clear short of giving your email address to download.
