Terms of use
By using Bailleur Lucide (the site and its Claude connector), you accept these terms. They are short; please read them.
This is an English translation provided for convenience. The French version (“Conditions d’utilisation”) is the only legally binding one and prevails in case of any difference.
Last updated: 31 October 2026.
The service
Bailleur Lucide is a free rental-return simulator, published on a non-professional basis by a private individual (see the legal notice). It is provided as is, with no guarantee of availability, accuracy or fitness for a particular purpose. It may change, be interrupted or stop at any time.
Estimates, not advice
Results are estimates computed from your data and simplified assumptions (described in the methodology). They are not investment, tax or legal advice. Check important figures with a professional before any decision.
You alone are responsible for the data you enter (or that Claude sends on your behalf) and for the decisions you take.
Your account
You keep your password confidential and you are responsible for what is done from your account. You can ask for your account to be deleted at any time at the contact address.
The Claude connector
The connector can only be used from Claude (Anthropic), after your authorisation on the consent page. It only has the access you grant (evaluate listings, read your properties, create and change properties after your confirmation); it can neither delete nor share your properties, nor change a portfolio.
With a free account, the connector saves 1 property, as on the site; evaluations, charts, comparisons and changes to your property stay unlimited.
Its use is limited (number of calls per minute and per day). The publisher may suspend or withdraw an access, or close the connector, in particular in case of abuse or of a risk to security or to the service. You can remove the access at any time from the site’s “Claude” page (the “Claude” link at the top of the page, then “Connected apps”).
Your use of Claude itself is governed by Anthropic’s terms and privacy policy.
Acceptable use
Abusive use of the service is forbidden: automated mass extraction, getting around the limits or access controls, trying to access another user’s data, disrupting the service, unlawful use. The forum follows its own rules, set out in the legal notice.
Intellectual property
The site’s texts, layout and code belong to the publisher. The reports you generate from your own data belong to you.
Liability
As the service is free and provided as is, the publisher cannot be held liable for indirect damage or for a decision taken on the basis of its results, within the limits allowed by law. Nothing in these terms excludes a liability that cannot lawfully be excluded.
Changes, governing law, contact
These terms may change; the update date is shown at the top of the page. They are governed by French law. If there is a problem, write to the contact address first.
