Purpose
These terms and conditions (the "Terms") govern the subscription to the Kahn Real Estate online software (the "Service"), published by the business identified in the legal notice (the "Publisher"), by anyone who manages short-term rental homes — owner, concierge service or agency (the "Customer"). This is a translation: only the French version is binding.
By creating an account, the Customer declares having read and accepted the Terms, including their appendix on personal data processing. They prevail over any other document, unless otherwise agreed in writing.
Definitions
"Account": the Customer's space in the Service, and the access it opens to its team, owners and service providers. "Property": a home managed through the Service. "Platforms": the booking sites (Airbnb, Booking.com, Vrbo…) where the Customer lists its Properties. "Channel manager": the third-party service (Beds24) through which the Service exchanges calendars, prices and bookings with the Platforms. "Guest": the person staying in a Property. "Customer Data": the information the Customer and its users enter into, or bring into, the Service.
Account and access
The Customer creates its account online and provides accurate information, which it keeps up to date. Access uses a code sent to each user's email address; the Customer makes sure these addresses remain under the control of the persons concerned.
The Customer is responsible for the use of the Service from the accounts it opens and for the rights it grants. It notifies the Publisher without delay of any access it believes to be fraudulent.
The Service
The Service lets the Customer follow the bookings and calendar of its Properties, organise cleaning and interventions, communicate with guests, owners and team, keep the welcome guidebook, issue statements and invoices to owners, and list its Properties on the Platforms through the Channel manager.
The Publisher develops the Service. It may change its features, without removing a feature essential to the current subscription without notifying the Customer at least thirty days in advance.
Platforms and channel manager
The Customer alone keeps the contractual relationship with each Platform. It remains responsible for its listings, prices, calendars, the bookings it accepts and compliance with each Platform's terms.
Exchanges with the Platforms go through the Channel manager, an independent third party. They are never instantaneous, and the Publisher guarantees neither the availability of the Platforms nor that of the Channel manager. The Customer checks its calendar and has, on each Platform, the means to correct an error.
Price
The subscription costs €19.99 per Property per month. Each invoice counts the Properties connected to the Service on the day it is issued, without proration: a Property added during the month is billed from the next invoice.
As long as the Publisher benefits from the French VAT franchise, its prices are net and its invoices state "TVA non applicable, article 293 B du CGI". Should it become liable for VAT, VAT will be added to the price excluding tax.
The Publisher may change its prices. It informs the Customer at least thirty days in advance; a Customer who refuses the new price terminates before it takes effect, at no cost.
Billing and payment
The subscription is paid monthly, in advance, by card or direct debit, through the payment provider Stripe. Invoices are available in the Service's billing area.
Late payment by a business Customer incurs penalties at the European Central Bank rate plus ten points, and the fixed €40 recovery fee. After a formal notice left unanswered for fifteen days, the Publisher may suspend access to the Service until payment.
Term and termination
The subscription is monthly, with no minimum term. The Customer may terminate it at any time from the billing area; termination takes effect at the end of the current, already paid month, with no refund of the period started.
The Publisher may terminate the subscription for a serious breach of the Terms by the Customer, fifteen days after a formal notice left unanswered, or immediately in case of fraudulent or unlawful use of the Service.
Right of withdrawal
A Customer acting as a consumer has fourteen days from sign-up to withdraw, without giving reasons, by writing to bonjour@kahnrealestate.fr. If it asked for the Service to start during that period, it pays for the service provided until withdrawal, pro rata.
End of subscription and return of data
When the subscription ends, access to the Service is closed. On the Customer's written request within thirty days, the Publisher provides a copy of its data in a common, readable format (CSV or JSON). After that period, Customer Data is deleted, except data the law requires to keep, such as invoices, and backups, which are erased as they rotate.
Personal data
For the data of its guests, owners, team and service providers, the Customer is the controller and the Publisher acts as processor, under the appendix below.
For the data of its customers' accounts, billing and security, the Publisher is the controller, under the privacy policy.
Customer obligations
The Customer complies with short-term rental regulations (declaration or registration of Properties, applicable night limits, collection and payment of tourist tax), consumer law towards its guests, and the rules of any mandate binding it to owners.
It holds the rights to the content it publishes (photos, texts), ensures it is accurate and lawful, and informs the persons whose data it brings into the Service.
It does not use the Service for unlawful purposes, does not attempt to access another customer's data, does not disrupt its operation and does not extract its code.
Availability and security
The Publisher uses reasonable means to keep the Service available and secure: hosting in France, encrypted exchanges, isolation of each customer's data, regular backups. It may interrupt it for maintenance, limiting the length and frequency of such interruptions. It is bound by an obligation of means only.
Liability
The Publisher is liable for direct damage caused by a proven breach of its obligations. It is not liable for indirect damage, nor for damage arising from a Platform, the Channel manager, an input error by the Customer or force majeure.
Towards a business Customer, and to the extent permitted by law, the Publisher's total liability is limited to the amounts paid by the Customer for the subscription during the twelve months preceding the event giving rise to liability.
Intellectual property
The Service, its code, interfaces and trademarks remain the Publisher's property. The subscription grants the Customer a personal, non-exclusive right of use for the term of the subscription.
Customer Data remains the Customer's property. It authorises the Publisher to process, host and transmit it to the Platforms and the Channel manager only as far as the Service requires.
Changes to the Terms
The Publisher may change the Terms. It informs the Customer at least thirty days before they take effect, and the Customer accepts them at its next sign-in. A Customer who refuses them terminates its subscription, at no cost, before they take effect.
Force majeure
Neither party is liable for a failure caused by a force majeure event within the meaning of article 1218 of the French Civil Code, for as long as it lasts.
Complaints and mediation
Complaints should be sent to bonjour@kahnrealestate.fr. A consumer Customer may use, free of charge, the consumer mediator whose details the Publisher provides on request, as well as the European online dispute resolution platform.
Governing law and disputes
The Terms are governed by French law. Failing an amicable solution, a dispute with a business Customer is brought before the courts of the Publisher's registered office; a consumer Customer refers to the court designated by law.
