They seemed to have changed the wording since you posted the comment, now specifying exactly 30 days with seemingly no exceptions.

These terms seem to be updated at-will, so I'll take that with a grain of salt however.

That's strange. Even in my hobby-toy app, I have a TOS that I bump whenever the terms meaningfully change, and in my app, it forces a re-acceptance of the new terms before using the app again.
