+# Terms of Service
+
+These terms cover the **Commit Check GitHub App** — the hosted service we run,
+which you install onto your GitHub account. The command-line tool, the
+pre-commit hooks, the GitHub Action and the MCP server are not covered here:
+they run inside your own environment and are governed by the [MIT
+licence](https://github.com/commit-check/commit-check/blob/main/LICENSE) of the
+repository you got them from.
+
+Installing the App means you accept these terms.
+
+## What the service does
+
+The App reads the commits of a push or pull request and the repository's
+configuration file, evaluates them against the rules that file turns on, and
+posts the result as a GitHub check run. That is all it does. It never writes to
+your repository, never rejects a push, and never blocks a merge on its own — a
+failing check only blocks a merge if you make it a
+[required status check](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches#require-status-checks-before-merging)
+yourself.
+
+What it reads and what it stores is set out on the [privacy page](privacy.md).
+
+## Your side
+
+You are responsible for the repositories you install the App on, for the rules
+you turn on, and for having the right to install it on an organization's
+repositories. Do not attempt to disrupt the service — for instance by sending
+traffic designed to exhaust it, or by probing it for vulnerabilities without
+telling us first. If you find a security problem, please
+[report it](https://github.com/commit-check/commit-check/security/policy) rather
+than exploiting it.
+
+## Plans, billing and trials
+
+**Nothing is charged today.** The Marketplace listing is not published yet, so
+there is no plan to buy and every repository is checked at no charge. This
+section describes what will apply once it is; the
+[pricing section](index.md#pricing) and the
+[App guide](guides/github-app.md#plans) say the same, and will say so before
+anything changes.
+
+Public repositories are free on any account, and so is everything on a personal
+account. An organization's private repositories will be covered by the Team
+plan, at the price shown in the pricing section.
+
+Billing, trials, renewals, cancellations and refunds will be handled by GitHub
+under the [GitHub Marketplace Terms of
+Service](https://docs.github.com/en/site-policy/github-terms/github-marketplace-terms-of-service),
+not by us — we never see your payment details. The Team plan comes with a
+14-day free trial; cancelling is done from your GitHub account's billing
+settings and takes effect at the end of the current period.
+
+If the price changes, the change applies to your account from the next
+renewal, and GitHub notifies you.
+
+## Availability
+
+The App is offered as is. We aim to keep it running and to fix what breaks, but
+we do not promise a level of uptime, and there is no support commitment beyond
+the [issue tracker](https://github.com/commit-check/commit-check/issues).
+We may change how the service works, or stop running it, with notice on this
+site and on the Marketplace listing.
+
+If the hosted App stops being available to you, the
+[GitHub Action](guides/github-actions.md) reads the same configuration file and
+reports the same rule IDs. Nothing you write in `cchk.toml` is locked to the
+hosted service.
+
+## Liability
+
+To the extent the law allows, the App is provided without warranty of any kind,
+and we are not liable for indirect or consequential loss arising from using it
+— including anything that follows from a check run that passed when you think
+it should have failed, or failed when you think it should have passed. Commit
+Check validates commit metadata; it is not a review, a test suite or a security
+control, and it is not a substitute for any of them.
+
+Where liability cannot be excluded, it is limited to what you paid for the
+service in the twelve months before the claim.
+
+## Ending it
+
+You can end these terms at any time by uninstalling the App from your account.
+We may suspend or end an installation that breaches these terms, or that is
+being used to disrupt the service.
+
+## Changes to these terms
+
+Changes are published on this page, and the date below changes with them.
+Continuing to use the App after a change means you accept it. If a change
+matters materially to paying accounts, we will also note it on the Marketplace
+listing.
+
+## Contact
+
+[Open an issue](https://github.com/commit-check/commit-check/issues) for
+anything about these terms or the service.
