The license says it's free for personal or educational use. The only real restrictions prohibit commercial use, redistributing, reverse engineering, disassembling, and decompiling without permission. While that is a a lot less restrictive than most licenses, most of those restrictions are also rather curious. It pretty much negates the value of the software as an educational tool, reducing it to a technology demo.
Prohibiting disassembling is worth about as much as "do not open, no user-serviceable parts inside" warnings ---- you are a true hacker only if you ignore them.
