Waste of my time

Thought this looked cool so I downloaded it to give it a try. The first thing it needs is an account where I need my email address. Im not opposed to setting up an account for something that I want, but in this case I dont even get to the see the interface before I need an account. If these people were serious they would allow users to try as a guest and then after a week or two make an account. How do I know what they are going to do with my email?
