Terms of Service

LitmusLayer is a business-to-business service. You may use it only in the course of a business, and you must be at least 18 years old. These terms apply to the website, the application, APIs, feeds, and any emails or exports the service produces.

LitmusLayer monitors what third-party AI models say about your brand, extracts and verifies factual claims against facts you provide, scores risk, flags potential regulatory exposure, generates suggested corrections, and maintains a tamper-evident audit ledger of these activities. The service is under continuous development; features may be added, changed or withdrawn (see section 16).

• You must provide accurate registration information and keep it current.
• You are responsible for everything done under your account, and for safeguarding access to the email address you sign in with. Notify us immediately of any suspected unauthorised access.
• Organisation owners and admins control who is invited to their workspace and what role they hold. Adding a team member gives that person access to your workspace data according to their role.
• You may only monitor brands you own, represent, or are authorised to act for.

You retain all rights to the content you provide — brand facts, evidence documents, prompts and configuration ("Customer Content"). You grant us a worldwide, non-exclusive licence to host, process, transmit and display Customer Content solely to provide and secure the service, including sending relevant excerpts to the AI model providers listed in our Privacy Policy.

This part matters: the service verifies AI statements against the facts you provide. You are solely responsible for ensuring your brand facts are accurate, current, substantiated and lawful. A verification, correction or compliance record built on facts that are wrong is itself wrong — and that responsibility is yours, not ours. You warrant that you have all rights needed to provide your Customer Content and that it does not infringe anyone else's rights.

You must not use the service to:

• publish, propagate or substantiate information you know or should know is false or misleading — including using correction tools to seed inaccurate claims about your own products or to disparage or defame a competitor;
• monitor a brand you have no right to represent, or impersonate another organisation;
• break the law, infringe intellectual property, or violate the terms of the AI model providers the service queries;
• probe, scan, overload or interfere with the service or its security controls, or attempt to access another organisation's data;
• reverse engineer, scrape, resell or white-label the service, or use it to build a competing product;
• upload malware or content that is unlawful, or use automated means to abuse quotas, rate limits or free trials.

We may suspend or terminate accounts that breach this section (see section 15).

Parts of the service are produced by AI models — claim extraction, verification assessments, risk scores, suggested corrections and report summaries. You acknowledge and agree that:

• AI outputs can be wrong. Assessments are probabilistic judgements, not facts. Confidence scores are estimates, not guarantees. You must apply human review before relying on or acting upon any output — the service is designed to require your explicit approval before any correction is deployed, and that approval is your decision and responsibility.
• Monitoring is sampling, not surveillance. The service queries selected AI models with selected prompts at intervals. It does not and cannot capture everything every AI system says about your brand, and absence of a detection is not proof that no misstatement exists.
• We cannot control third-party AI models. Corrections and published feeds are designed to increase the likelihood that AI models pick up accurate information. Whether, when and how any third-party model changes its answers is outside our control, and we make no promise that it will. Estimated propagation windows are estimates only.
• Assessments (including terms like "defamatory" used in the interface) are technical classifications for triage, not legal determinations or legal advice.

Regulatory flags, posture summaries, substantiation ledgers and export packs are informational tools that help you and your advisers assemble evidence. They are not legal advice, do not guarantee compliance with the EU AI Act, FTC requirements, UK ASA codes, the DPDP Act or any other law or regime, and do not create an adviser–client relationship. Regulatory interpretation changes; consult qualified counsel for legal decisions.

The service depends on third-party providers — AI model APIs, hosting, database, email (listed in our Privacy Policy). We are not responsible for their availability, changes to their APIs or terms, or their outputs. If a provider withdraws or restricts a capability, we may modify the affected feature and will do so as reasonably as we can.

• Trial workspaces are provided as-is and may be limited, suspended or ended at any time. We may delete trial data 30 days after a trial lapses without conversion.
• When paid plans are enabled, fees, billing periods and plan limits will be shown at purchase. Fees are exclusive of taxes and non-refundable except where the law requires otherwise.
• We may change pricing with at least 30 days' notice; changes apply from your next billing period.
• Payment processing is handled by Stripe — we never store card numbers.

We own the service — software, models of operation, design, documentation and branding. These terms grant you a limited, non-exclusive, non-transferable right to use the service for your internal business purposes during the agreement, and nothing more. If you send us feedback or suggestions, we may use them without restriction or obligation.

Each party will protect the other's non-public information with at least reasonable care and use it only to perform under this agreement. This does not apply to information that is public, independently developed, or lawfully received from a third party, and either party may disclose where required by law (with notice where lawful).

The service is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim all warranties, express or implied — including merchantability, fitness for a particular purpose, non-infringement, accuracy of outputs, and uninterrupted or error-free operation. Nothing in these terms excludes warranties that cannot lawfully be excluded.

To the maximum extent permitted by law:

• Neither party is liable for indirect, incidental, special, consequential or punitive damages, or for loss of profits, revenue, goodwill or data — even if advised of the possibility.
• Our total aggregate liability arising out of or relating to the service is capped at the amount you paid us in the 12 months before the event giving rise to the claim, or £100 if you have paid nothing.
• We are not liable for statements made by third-party AI models about you or anyone else, for decisions you take based on outputs of the service, or for the consequences of corrections you approve and deploy.

Nothing in these terms limits liability for fraud, wilful misconduct, death or personal injury caused by negligence, or anything else that cannot lawfully be limited.

You will defend and indemnify us against third-party claims, losses and costs (including reasonable legal fees) arising from: your Customer Content; your breach of these terms (including section 4 warranties and section 5 acceptable use); corrections or publications you approve; or your monitoring of a brand you were not authorised to represent.

• You may stop using the service and request account deletion at any time by emailing us.
• We may suspend or terminate access immediately where we reasonably believe there is a breach of these terms, a security risk, legal exposure, or abuse of the service — and otherwise on 30 days' notice.
• On termination your right to use the service ends. You have 30 days to request an export of your Customer Content, after which we delete it in line with the retention periods in the Privacy Policy (audit ledger entries are retained as described there).
• Sections that by nature survive termination do so — including 4, 6, 7, 10–14, 17 and 18.

We may modify the service, and we may update these terms as the service or the law changes. For material changes we will give notice by email or in-app at least 14 days before they take effect; continued use after that date is acceptance. If you do not agree, stop using the service before the changes take effect.

These terms are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction over disputes arising from them — except that either party may seek injunctive relief in any competent court, and nothing deprives you of mandatory protections of the law of the country where you are established. Before starting formal proceedings, the parties will attempt in good faith to resolve any dispute by negotiation for 30 days.

• Entire agreement — these terms, the Privacy Policy and the Cookie Policy are the whole agreement and supersede prior discussions.
• Severability — if a clause is unenforceable, the rest stays in force.
• No waiver — not enforcing a clause is not a waiver of it.
• Assignment — you may not assign this agreement without our consent; we may assign it in connection with a merger, acquisition or sale of assets.
• Force majeure — neither party is liable for delay or failure caused by events beyond its reasonable control.
• Notices — we give notice via the email on your account or in-app; you give notice at privacy@litmuslayer.com.
