I went to the link you provided and looked at two pages served up by their website and after reading their terms of use I am not so sure that I would trust them for the following reasons:
1. They provide no way to contact them directly from their website and no FAQ. Perhaps they do with their client software but I don't think it is very smart to download and install it blind.
2. In paragraph numbered 1 of their Terms of Use they claim that they have a Privacy Policy because "my privacy is important"and that it is linked from the bottom of each page on their site. Well neither of the pages I viewed had such a link! And, of course, by merely accessing their site I agree to their terms of use including their un-findable and therefore unreadable Privacy Policy.
3. Their Terms of Use also includes language basically designed to prevent the posting of any information critical of the site.
4. Finally their Terms of Use seem to prevent the posting of a url pointing to their site without their express written consent. So, unless you had that when you posted the link you may be in violation of their Terms of Use if you are a user of their site. (Of course, maybe I'm wrong about that portion of their Terms of Use but I don't want to go back to their site and check because I might be correct since I now know what their Terms of Use include and I do not wish to be bound by them.)
Conclusion - probably over-lawyered and sloppy site design, i.e., they haven't followed their own rules. So, why would I want to trust them?
