Ringfence is a product of Settleby Ltd, a company registered in England and Wales (No. 15107426, VAT GB448267759).
These Terms of Service ("Terms") govern your use of Ringfence ("Service"), including the ringfence command-line tool, local proxy, and the cloud dashboard at ringfence.dev. Ringfence is operated by Settleby Ltd ("we", "us", "our"), a company registered in England and Wales under company number 15107426. We are referred to in these Terms as Ringfence and Settleby interchangeably.
By creating an account, installing the local agent, or otherwise using the Service, you agree to these Terms. If you are using the Service on behalf of an employer or organisation, you represent that you have authority to bind that organisation, and "you" refers to that organisation.
Ringfence is a budget firewall for AI coding agents. The local agent ("fence") runs on your machine, intercepts requests to upstream AI providers (such as Anthropic), and applies hard daily and monthly cost caps. The optional cloud dashboard provides shared visibility for teams using the local agent.
The local agent is provided free of charge with no expiry. The cloud dashboard is provided on a subscription basis under the plans described at ringfence.dev/#pricing.
We do not provide the underlying AI services. Your use of those services is governed by the terms of the relevant provider (for example, Anthropic). You are responsible for complying with those terms.
You must provide an accurate email address and verify it before using the cloud dashboard. You are responsible for the security of your account credentials and for any activity carried out under your account.
The Service is intended for users aged 16 or over. The Service is not directed at children, and we do not knowingly process data from anyone under 16.
Paid plans are billed monthly in advance through Stripe. Your subscription renews automatically at the end of each billing period until you cancel. You may cancel at any time from the team settings page; cancellation takes effect at the end of the then-current billing period and you retain access until that point.
Fees are exclusive of applicable taxes (including VAT). Stripe collects taxes where required and shows them at checkout. We may change pricing on at least 30 days' notice; changes apply from your next renewal.
Except where required by law, paid fees are non-refundable. Downgrading or cancelling does not entitle you to a partial refund of the current billing period.
You agree not to:
We may suspend or terminate access if we reasonably believe you are in breach of this section.
The local agent runs on your machine and processes prompts, completions, and source code locally. That content is never transmitted to Settleby. Only token-count metadata, model identifiers, timestamps, and cost figures are sent to the cloud — see the Privacy & Cookie Policy for the precise data flow.
You retain all ownership and intellectual-property rights in the content you process through the Service. You grant us a limited, non-exclusive licence to process the metadata described in the Privacy & Cookie Policy solely for the purpose of providing and improving the Service.
The Ringfence software, branding, dashboards, and documentation are owned by Settleby Ltd or its licensors and are protected by copyright and other laws. We grant you a limited, non-exclusive, non-transferable licence to install and use the Service in accordance with these Terms. Open-source components included in the Service are licensed under their respective licences, which take precedence over this clause for those components.
We aim to keep the cloud dashboard available continuously but do not guarantee uninterrupted, error-free operation. We may modify, suspend, or discontinue features with reasonable notice where commercially reasonable. The local agent does not depend on the cloud being available, and budget enforcement continues to function while the cloud is offline.
To the maximum extent permitted by law, the Service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will detect or prevent every misconfiguration of an upstream AI provider or that token-count and cost figures derived from upstream responses will be exactly accurate in every edge case.
Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud, or any other liability that cannot be excluded under applicable law.
Subject to clause 9, our total aggregate liability under or in connection with these Terms — whether in contract, tort (including negligence), breach of statutory duty, or otherwise — is capped at the greater of: (a) the fees you paid to Settleby in the twelve months preceding the event giving rise to the claim, and (b) GBP 100.
We are not liable for indirect or consequential losses, including loss of profit, loss of revenue, loss of data, business interruption, or wasted management time, even if foreseeable.
You agree to indemnify and hold Settleby harmless against claims, losses, and reasonable legal costs arising from: (a) your breach of these Terms; (b) your misuse of the Service; or (c) content you process through the Service that infringes third-party rights or violates applicable law.
Either party may terminate these Terms at any time. You may terminate by closing your account from team settings or by emailing hello@ringfence.dev. We may terminate for material breach with 14 days' notice (or immediately for breaches of clause 5).
On termination, paid features become unavailable. We will retain data only as long as needed to comply with the Privacy & Cookie Policy and applicable law. The local agent continues to function on your machine after termination of the cloud subscription.
We may amend these Terms from time to time. Material changes will be notified by email to your account address at least 14 days before they take effect. Continued use of the Service after the effective date constitutes acceptance.
These Terms and any non-contractual obligations arising from them are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction, except that we may bring proceedings in the courts of the country where you are established to recover unpaid fees.
Before bringing a claim, please contact us at hello@ringfence.dev. We will use reasonable efforts to resolve any dispute informally within 30 days. Nothing in this clause restricts your statutory rights as a consumer where applicable.
These Terms (together with the Privacy & Cookie Policy and, for paid customers, the Data Processing Addendum) form the entire agreement between you and Settleby in relation to the Service. If any clause is held invalid, the remainder continues in force. Failure to enforce any clause is not a waiver. You may not assign these Terms without our consent; we may assign them to an affiliate or successor in connection with a corporate reorganisation.
