What are terms of service?
Terms of service are the contract between you and the people who use your website or app. They set the ground rules: who may use the service, what counts as acceptable use, who owns content, what you promise (and don't), and what happens when something goes wrong.
Good terms protect you — they limit your liability, give you a basis to remove bad actors, and make your relationship with users predictable.
Match the terms to your service
Turn on only the clauses that fit what you do. If users create accounts, include the accounts clause; if they post content, include the user-content license; if you sell things or run subscriptions, add the purchases and billing clauses.
Keeping the terms aligned with your real features makes them clearer and more enforceable.
Pair it with a privacy policy
Terms of service and a privacy policy do different jobs, and most sites need both. The terms govern use of the service; the privacy policy explains how you handle data. You can generate a matching privacy policy on this site in a few minutes.
