Terms of service

“Catalot”, “we” or “us” means Catalot EURL, a company with its registered office in Paris, France, founded in 2026. “Service” means the Catalot website and application. “You” means the person accepting these terms, on their own behalf or on behalf of an auction house or dealership. “Lot” means one object catalogued through the Service. “Notice” means the text the Service writes for a Lot. “Content” means the photographs, notes and house style you submit.

An account requires a valid email address, which you verify before use, and a password you keep confidential. One account belongs to one person; seats on the Maison plan are named and not shared. You are responsible for everything done through your account, and you tell us at contact@catalot.pro as soon as you suspect it has been used by someone else. We may suspend an account we reasonably believe to be compromised.

The Service is sold by monthly volume of Lots. The Free plan allows ten Lots a month, Cabinet two hundred, Maison one thousand. A Lot is counted when a Notice is generated for it; editing, regenerating a failed run, translating or exporting an existing Notice does not count again. Quotas are enforced on the server and reset on the monthly anniversary of your first generation.

The Free plan is free, with no card, and stays free. It carries the same writing engine, the same two languages, the same editable notices and the same CSV export as the paid plans, with a lower monthly volume. We may change the volume of the Free plan for new accounts, but we will not turn it into a time-limited trial for accounts already on it without at least thirty days' notice.

Paid plans are billed monthly or annually in advance, in euros, by the payment method you register. Annual billing is charged as ten months of the monthly price. Prices are exclusive of VAT, which is added where applicable. To upgrade, downgrade or cancel, write to contact@catalot.pro; changes take effect the same business day, upgrades are charged pro rata, and downgrades apply from the next period. Invoices are issued electronically for every payment.

You may use the Service for cataloguing objects you are entitled to catalogue. You may not: submit photographs you have no right to use; submit images of people as the subject of a Lot, or any unlawful, stolen or protected cultural property you cannot legally offer; attempt to extract our prompts, models or source code; resell raw Service output as a competing generation service; run automated load beyond your plan; or use the Service to produce descriptions you know to be false.

You keep every right you already had in your photographs, your notes and your house style. Nothing here transfers ownership to us. You grant Catalot a non-exclusive, worldwide licence, limited to the duration of your account, to host, reproduce, transmit and process that Content solely in order to run the Service for you — that is, to generate, store, display and export your Notices. We do not publish your photographs, do not use them to train models, and do not license them to anyone else. Delete a Lot and the licence over its Content ends with it.

A Notice is a draft written by an automated system from photographs. It may be incomplete, imprecise or simply wrong about a material, a period, a mark or a condition detail. Catalot gives no valuation, no estimate and no verdict on authenticity or attribution, and any wording that resembles one must be treated as an error rather than an opinion. You are the cataloguer: you read, correct and approve every Notice, and you alone are responsible for the catalogue you publish, for its legal descriptions and for the consequences of any sale made on the strength of them.

The Service itself — its software, interface, design, typography, prompts and documentation — belongs to Catalot EURL and is protected by French and international law. These terms grant you a right to use the Service, not a right in it. As between you and us, the text of the Notices generated for your Lots is yours to use, publish, edit and sell without restriction or attribution.

Each party complies with the GDPR. For your account data and the Content you submit, Catalot acts as controller in respect of running the Service and as processor in respect of any personal data your Content happens to contain, processing it only on your instructions. Our sub-processors, retention periods and security measures are set out in the privacy policy, which forms part of these terms.

We aim to keep the Service available at all times but we do not promise uninterrupted operation. Generation depends on a third-party model provider and may be slowed or interrupted by it. We may take the Service down for maintenance, with notice where the work is planned. No service-level agreement or availability credit is offered on any plan; if a paid outage lasts more than forty-eight consecutive hours we will extend your period by the time lost, on request.

Nothing in these terms excludes liability for death, personal injury, fraud, or anything else that cannot be excluded under French law. Subject to that, our total liability arising out of the Service, on any basis, is capped at the fees you paid us in the twelve months preceding the event, and we are not liable for lost profit, lost sales, lost data you could have exported, reputational harm, or the consequences of publishing a Notice you did not check.

You may close your account at any time from your settings or by writing to us; closure takes effect immediately and paid periods already started are not refunded except where French consumer law requires it. We may suspend or terminate an account for a serious or repeated breach of section 6, for non-payment thirty days after a reminder, or if we stop offering the Service. Before deletion you have thirty days to export your Notices as CSV.

We may change the Service and these terms. Substantive changes to the terms are announced by email at least thirty days before they take effect; continuing to use the Service after that date is acceptance. If you refuse a change, close your account before it applies and we refund the unused part of any prepaid period. Price increases never apply to a period already paid for.

These terms are governed by French law. Any dispute we cannot settle amicably will be brought before the competent courts of Paris, France. Consumers keep the right to bring proceedings in the courts of their own place of residence and to use the European Commission's online dispute resolution platform.
