ToS are rules set by and for the specific platform that define (1) HSPs’ responsibilities to their users, and (2) the appropriate and permitted, but also prohibited conduct and content on that platform. Users have to accept these terms if they want to use HSPs’ services.

Synonyms used for ToS are, for instance, terms of use, terms and conditions, or community standards. The TCO uses the phrase ‘terms and conditions’ and defines it as “all terms, conditions and clauses, irrespective of their name or form, which govern the contractual relationship between a hosting service provider and its users” (TCO Regulation, Art. 2.8).
