The default terms and rules and privacy policy help pages.
The content of help pages is stored as templates and they are named in the convention of _help_page_<page_id>.
However, for the terms and rules and privacy policy, the contents only consist of a single phrase, so you'd might as well just edit the phrases which are terms_rules_text and privacy_policy_text respectively.
