am I using a trial version?

am I using a trial version?

Hi,

Compliments to a great website and great service!

I have been going through different websites for web project management, and they all say "You get a trial version of 30 days"

I was wondering if this website is the same?
Or does a free account stay for as long as you want to keep it?

I think some people may be wondering about the same thing.

I need this information for a school project.

Thanks :)
