1. Purpose and acceptance
These terms and conditions of sale (the "Terms") govern the sales concluded on the Rookprint website (rookprint.rocket-ia.fr) between AI ROCKET (the "Seller") and any person placing an order (the "Customer"). Every order requires prior and unreserved acceptance of the Terms, given by ticking a box at the time of payment, which is never ticked in advance. The applicable Terms are those of the version in force on the date of the order, recalled in the confirmation email; the Seller may amend them for the future.

Email: fhermand.pro@gmail.com. Full legal information is given in the legal notice.
3. Products and services offered
The Rookprint website describes its service as follows: "Your chess DNA, read from your last 200 online games".
Rookprint provides a personal chess improvement report about one player's account on Lichess or Chess.com: the last 200 finished public games of standard chess (or fewer if the account has fewer) are analyzed with the Stockfish chess engine, statistics are computed by Rookprint's software, and the report text is written by an artificial intelligence model from those statistics. The report includes recurring weaknesses, opening results, clock management, errors by game phase, exercises taken from the player's own games (50, or 100 for the Progress option) and a 30-day training plan.
The report is delivered as a PDF file and a PGN file of exercises, made available on the order page and by email, usually within 10 to 20 minutes of payment, and kept for 30 days. The Progress option adds a second report produced 30 days after the first one, on the games played in between, sent by email. The Club pack covers five players.
The main characteristics of each plan are presented on its page and recalled before payment:
- Report: Your last 200 games analyzed by Stockfish, your 3 recurring weaknesses with numbers, 50 exercises from your own mistakes and a 30-day plan.
- Progress: Everything in Report with 100 exercises, plus a second report 30 days later that compares before and after.
- Club pack: Five reports for five players of a club, a coach or a chess school, each with 50 exercises and a 30-day plan.
4. Ordering
The Customer chooses a plan and its options, then reviews the order summary and the total price before paying. The Customer gives a valid email address, to which the confirmation, the invoice and, where applicable, the delivered files are sent. A customer account is optional: it gives access to past orders and invoices with a one-time code sent by email. The order is final once payment is confirmed; an acknowledgement is then sent by email.
5. Prices
Prices are those displayed on the website at the time of the order, in USD.
| Plan or option | Price |
|---|---|
| Report | $29 |
| Progress | $49 |
| Club pack | $149 |
« TVA non applicable, article 293 B du CGI » (French VAT exemption scheme for small businesses): the Seller does not charge VAT. The price displayed at the time of the order is the total amount payable; it is the only one that applies.
A promotional code, when one is offered, is applied to the summary before payment; it cannot be combined or exchanged for cash unless stated otherwise.
6. Payment
Payment is made online when ordering, by bank card or by the other methods shown on the payment page, through the payment provider Stripe. The Seller never has access to card details. The charge appears on the Customer's statement as "ROOKPRINT". The order is only carried out once the provider has confirmed the payment. A numbered invoice is issued for every paid order and sent by email; it remains available in the customer account.
7. Delivery and performance times
- Report: content made available as soon as payment is confirmed, by email and in the customer account.
- Progress: content made available as soon as payment is confirmed, by email and in the customer account.
- Club pack: content made available as soon as payment is confirmed, by email and in the customer account.
If an incident prevents delivery within the stated time, the Seller informs the Customer by email and offers a new date or a refund of the order. Failing delivery within the stated time or within a reasonable additional period, the Customer may terminate the contract under articles L216-6 et seq. of the French Consumer Code.
8. Right of withdrawal
A consumer Customer in principle has fourteen days from the conclusion of the contract to withdraw from a distance contract without giving any reason (articles L221-18 et seq. of the French Consumer Code).
For "Report", "Progress" and "Club pack", performance begins as soon as payment is confirmed. Under article L221-28 of the French Consumer Code, the right of withdrawal cannot be exercised for a service that has been fully performed, nor for digital content not supplied on a tangible medium whose supply has begun, where the Customer expressly requested it and waived the right of withdrawal. At the time of payment, a separate box, never ticked in advance, lets the Customer request immediate performance and acknowledge the loss of the right of withdrawal once performance begins. This request, its date and the version of the Terms accepted are repeated in the order confirmation email.
If the Customer withdraws after requesting immediate performance of a service that has not yet been fully performed, the Customer pays an amount proportionate to the service provided until the Seller was informed of the withdrawal (article L221-25 of the French Consumer Code).
Model withdrawal form (to be completed and returned only if the Customer wishes to withdraw): "To AI ROCKET, 1 rue du Seigneur Foulque, 60240 Parnes, France, francois@rocket-ia.fr: I hereby give notice that I withdraw from my contract for the service below, ordered on …; name of the Customer; address of the Customer; date; signature (only if sent on paper)."
9. Legal guarantees
The Seller must supply content or a service that conforms to the contract. For digital content and services, the Customer benefits from the legal guarantee of conformity under articles L224-25-1 to L224-25-31 of the French Consumer Code, for two years from supply (for the whole supply period when supply is continuous); during the first year the Customer only has to show that the defect exists. The Customer may have the content or service brought into conformity without undue delay, free of charge, including any necessary updates, or failing that obtain a price reduction or terminate the contract with a full refund. A professional who obstructs the guarantee in bad faith is liable to a civil fine of up to 300,000 euros (article L242-18-1). The guarantee against hidden defects (articles 1641 to 1649 of the French Civil Code) also applies for two years from discovery of the defect. The French version of the statutory information box (decree no. 2022-946) prevails. A defect is reported to francois@rocket-ia.fr; the Seller responds as quickly as possible.
10. Nature of the analysis
The figures in the report are computed automatically from the Stockfish engine's evaluations; the explanations and the training plan are generated by an AI model. No human coach reviews the report. Engine evaluations at limited depth can occasionally be imprecise. The report is an educational aid: no improvement of the player's rating or results is guaranteed.
Rookprint only reads finished games published by Lichess or Chess.com. It never analyzes a game in progress and provides no assistance during a game.
11. Username supplied by the Customer
The Customer supplies the username of a Lichess or Chess.com account whose games are public. The Customer may order a report about another player's public account only for a legitimate purpose (for example a coach, a club or a parent with the player's agreement).
Rookprint is not affiliated with Lichess or Chess.com. Their names are used only to identify the accounts the service can read.
12. Failed analysis
If the report cannot be produced (for example because the account has become private or has fewer than 20 finished games) or a delivered file is missing or unreadable, the Customer may write to the contact address: Rookprint will either deliver the report or refund the order.
13. Liability
The Seller must perform the order in accordance with the contract. The Seller is not liable in the event of misuse by the Customer, the act of a third party or force majeure. Towards a business Customer, liability is limited to the amount of the order concerned and excludes indirect damage. Nothing in these Terms limits the rights granted to consumers by law.
14. Personal data
The data needed for the order are processed by the Seller to perform it, invoice it and keep proof of it. How they are processed, how long they are kept and the Customer's rights are described in the privacy policy.
15. Intellectual property
The content delivered to the Customer is licensed for the Customer's own use, within the limits described on the plan's page. The website, its brand, texts and code remain the property of the Seller or of their authors.
16. Complaints and mediation
Any complaint is sent to francois@rocket-ia.fr. Under articles L612-1 et seq. of the French Consumer Code, a consumer Customer may, after a written complaint that has not been resolved satisfactorily, refer the matter free of charge to the consumer mediator the Seller belongs to:
Sas Médiation Solution — Service du Médiateur du e-commerce (Mme Eliane SIMON, médiateur), 222 chemin de la bergerie, 01800 Saint Jean de Niost, https://www.sasmediationsolution-conso.fr.
The mediator must be contacted within one year of the written complaint sent to the Seller.
17. Governing law and language
These Terms are governed by French law, without prejudice to the more protective mandatory provisions of the law of the consumer Customer's country of habitual residence. Failing an amicable solution, disputes are brought before the competent courts. These Terms may be offered in several languages; in the event of any discrepancy, the French version prevails.
