Yes, Stykz is really free! In fact, our commitment is that there will always be a free version of Stykz available for download. (Note that we may end up making a more powerful version under another name and sell that commercially, but it won't affect the free version of Stykz.)
Do I Need a License?
No, not at all. You can use Stykz to create animations for use in any kind of destination environment, whether it be commercial, educational, or just for fun!
The only thing we ask is that it would be great if you could mention Stykz somewhere in your distributed materials, and optionally provide a link to our website.
Can I Redistribute Stykz?
You may redistribute Stykz in any way you like, so long as you distribute the exact same installer/zip file that you get when you download Stykz for the first time from the Stykz website; you aren't allowed to break it apart and distribute pieces. Oh, and of course, you can't sell the Stykz program in any way. :-)
