ChaiTrace subscription and licence terms

Translation provided for information: only the French version is legally binding.

In brief. ChaiTrace rents for €20 per month or €200 per year, VAT included, with no commitment and no price increase, after a 30-day free trial: nothing is charged during the trial, and the subscription starts automatically at its end, unless cancelled. Online sales are handled by Link, Stripe's payment service. The software is installed on your computer: your data stays with you. The software is in beta, and support replies within 24 hours. The subscription is reserved for professionals.

1. Purpose and publisher

These terms govern the free trial, the subscription and the use of the ChaiTrace software, in its full edition (hereinafter “the Software”). The Software is published by Lubin Rocher, a sole trader operating under the trading name Studio LR, 4 rue Pardessus, 41000 Blois, SIREN 130 711 146, lubin.rocher@studio-lr.fr (hereinafter “the Publisher”).

The customer (hereinafter “the Customer”) accepts these terms by signing up online, as the sign-up page refers to them; any sign-up constitutes acceptance without reservation.

2. Customers

The trial and the subscription are reserved for professionals (wine estates, wineries, wine merchants, educational establishments…) acting for the purposes of their business.

3. Description of the Software

The Software is a cellar traceability tool: plots and harvest, batches, vessels, movements and blends, analyses and fermentation monitoring, winemaking products, registers, bottling, labelling, management of several users. It is installed on a computer running Windows 10 or 11; tablets and phones on the same local network access it through their browser. The features are described in detail on the ChaiTrace page.

Declaration aids. The reports produced by the Software (cellar register, help with the monthly summary declaration to French customs, harvest declaration, labelling statements…) are data-entry aids and indicative summaries, drawn up from the data entered by the Customer. They constitute neither legal advice nor an official declaration. The Customer remains solely responsible for the accuracy of their entries, for checking the reports produced and for complying with their legal, tax and customs obligations.

Beta version. The Software is offered as a beta version: it has been used in real conditions since July 2026 and continues to evolve, and some defects may remain. The Customer reports them to the Publisher, who fixes them in the updates (article 9).

4. Free trial

• The trial is free and lasts 30 days, with all features enabled, from the online sign-up. Signing up requires a payment method (bank card or another method offered on the payment page); nothing is charged during the trial. The download link and the access key are provided upon sign-up, on the confirmation page.
• Only one trial is granted per estate.
• At the end of the trial, the subscription starts automatically, on the plan chosen at sign-up, and the first period is charged on that date. Link notifies the Customer by email a few days beforehand.
• The Customer may cancel at any time during the trial, online at app.link.com or by email to the Publisher: no amount is due, and the key is deactivated. The data entered remains on the Customer's computer, and the Customer gets it back if they subscribe later.

5. Subscription, price and payment

• The subscription is sold online through Link, Stripe's payment service, which acts as reseller (“Sold through Link”): Link collects payments, calculates and remits VAT, issues invoices and receipts, and handles requests relating to payment, refunds and disputes, under its own terms, which the Customer accepts on the payment page. These terms govern the trial, the licence and the use of the Software, as well as support.
• Two plans: monthly, at €20 per month, or annual, at €200 per year. These prices include all taxes: the VAT applicable to the Customer is included and shown on Link's invoice.
• The subscription is paid in advance, at the start of each period, by bank card or by another method offered on the payment page (Apple Pay, Google Pay, Link). By saving a payment method, the Customer authorises Link to charge the amount for each period when it falls due, until cancellation. The Publisher never has access to the full card number.
• The price of an ongoing subscription does not increase: as long as the subscription is not cancelled, the Customer pays the price in force when they subscribed.
• If a payment fails, Link retries it and notifies the Customer. If the payment has not been settled 15 days after a reminder, the Publisher may suspend the access key, then terminate the subscription.

6. Term and cancellation

• The monthly subscription renews from month to month, the annual subscription from year to year. Link notifies the Customer by email before each annual renewal.
• The Customer may cancel at any time, without charge or justification, online at app.link.com with the email address used to sign up, or by simple email to lubin.rocher@studio-lr.fr. Cancellation takes effect at the end of the period already paid for, which is not refunded pro rata, unless Link grants a refund under its own terms.
• The Publisher may terminate the subscription in the event of a serious breach of these terms by the Customer (sharing the key, circumventing the licence, non-payment), 15 days after a formal notice that has had no effect. The Publisher may also end the subscription with three months' notice if it ceases to sell the Software.
• At the end of the subscription, the access key is deactivated and the Software no longer opens. The data remains on the Customer's computer, in a file in the open SQLite format that belongs to the Customer; it is up to the Customer to export it (CSV, PDF) before the end. If the Customer subscribes again, they get their data back.

7. Licence to use

Ownership. The Software (source and object code, interface, database structure, documentation, graphic elements) is and remains the exclusive property of Lubin Rocher, protected by the French Intellectual Property Code (articles L.111-1 et seq., L.112-2, 13°). The subscription grants a right of use, never a transfer of ownership.

Scope. For the duration of the trial and then of the subscription, the Publisher grants the Customer a non-exclusive, non-transferable and non-assignable licence to use the Software: on one computer (one installation) per subscription, with the estate's tablets and phones able to access it over the local network, and for the Customer's own business needs.

Restrictions. Except with the Publisher's written permission, it is forbidden to copy the Software, other than a backup copy (article L.122-6-1 of the French Intellectual Property Code); to modify, adapt or translate it; to decompile it, beyond the limits of article L.122-6-1 IV of the same code; to rent it, lend it, make it available to third parties or share the access key; to circumvent or tamper with the licensing mechanism. Any violation exposes its author to the penalties for infringement (articles L.335-2 et seq.) and results in the automatic termination of the subscription.

Activation. The access key is activated online, then revalidated in the background whenever the computer is connected to the Internet. Between two validations, the Software works offline for 7 days: the computer must therefore be connected at least once a week. Only minimal data is transmitted: it is described in the privacy policy.

8. Customer data

The data entered in the Software belongs to the Customer and is stored on the Customer's computer. The Publisher has no access to it and receives no copy of it. The Software makes an automatic backup every day on the same computer; copies on a separate medium (USB stick, external drive) are the Customer's responsibility, and the Publisher cannot restore lost data. If this data includes personal data, such as the names of users, the Customer is its data controller.

9. Support and updates

During the trial and the subscription, the Publisher answers the Customer's requests within 24 hours, by email at lubin.rocher@studio-lr.fr or by phone, and provides updates to the Software, both fixes and new features, for download. Support covers the use of the Software: it includes neither troubleshooting the Customer's computer or network, nor entering the Customer's data.

10. Warranty and liability

The Publisher provides Software that conforms to its description and fixes, within a reasonable time, the defects reported to it. Except in the case of gross negligence or wilful misconduct, the Publisher's liability is limited to direct and foreseeable damage, and capped at the amounts paid by the Customer over the last twelve months. Indirect damage, such as operating losses or commercial loss, is excluded, as are data losses due to a lack of backups or to improper use.

11. Personal data

The data processed for the trial, the subscription and the activation of the key is described in the privacy policy.

12. Governing law and disputes

These terms are governed by French law. In the event of a dispute, the parties first seek an amicable solution. Failing that, where the Customer entered into the contract as a trader, the Commercial Court of Blois (tribunal de commerce) has sole jurisdiction (article 48 of the French Code of Civil Procedure); in other cases, the competent court is determined according to the ordinary rules of law.
