Pretty simple... Use at your own risk, we don't guarantee anything. (I mean, it's a free site we're doing for fun, right?)
We won't sell your data or send you spam. (We even hide your email address so spammers can't get to it. We hate spam.) We might send you news about the site.
We do have Google ads on the pages, and they mention the following privacy language:

These companies may use information (not including your name, address, email address, or telephone number) about your visits to this and other websites in order to provide advertisements about goods and services of interest to you.
