3. Publisher and contact

The NotiChess Software and the Service are published by NotiPro, a simplified joint-stock company (SAS) with a share capital of €3,000, registered with the Pau Trade and Companies Register under number 942 075 615, whose registered office is located at 2 avenue du président Pierre Angot, 64000 Pau, France (the “Publisher”). The publication director is Anthony Rambaut. “NotiChess” is a trademark operated by the Publisher.

For any question regarding these Terms, the Service, your Account or your Subscription, you may contact the Publisher by email at contact@notichess.com.

Payments relating to the Subscription and the Lifetime Licence are handled by the payment provider Stripe (Stripe Payments Europe). Information relating to the hosting of the website is set out in the legal notice, available on the site.

4. Description of the service

NotiChess is a desktop application available for Windows, macOS and Linux, designed for the analysis of chess games. The Software runs 100 % locally on your machine and without telemetry. It offers, in particular, analysis using the open-source engines Stockfish and Leela, access to a database of over-the-board (OTB) games comprising approximately 13 million games and updated daily, synchronisation with the Chess.com and Lichess platforms, and a sharing and coaching space.

Chess data (games and analyses) remains stored locally on the User's machine; the Publisher does not host this data. Only Account and Subscription data are hosted server-side. Use of the Software requires its download and installation on a device with sufficient hardware configuration; certain functions require an Internet connection, in particular Account management, updates to the games database and synchronisation with third-party platforms.

The Software is currently provided in BETA version: it is under development, made available “as is” and liable to change, be modified or contain imperfections. A version 1.0 is envisaged for September 2026; this date is given for indicative purposes only and is not contractual.

5. Access, account and eligibility

Using the Service requires the creation of an Account. You undertake to provide accurate, complete and up-to-date information when creating your Account, and to keep it updated should it change. Only one Account may be opened per User; Account sharing is prohibited.

You are responsible for keeping your login credentials confidential and for all activities carried out through your Account. You undertake to inform the Publisher without delay of any loss, theft or unauthorised use of your credentials or your Account, at contact@notichess.com.

Access to the Service is reserved for persons of legal age who have the legal capacity to enter into a contract. A minor may use the Service only under the responsibility and with the consent of a holder of parental authority, who subscribes to and accepts these Terms on the minor's behalf.

6. Software licence

The Publisher grants you a personal, non-exclusive, non-transferable and non-assignable right to use the Software, this right being revocable only in the event of a breach on your part under the conditions set out in the section relating to suspension and termination for breach. This right is granted for the duration of the Subscription or, in the case of the Lifetime Licence, on a perpetual basis under the conditions set out below. It is granted for strictly personal, non-commercial purposes.

You are authorised to install the Software on your personal devices, for one and the same User, namely the holder of the Account. As Account sharing and abusive concurrent use are prohibited, the Publisher may take reasonable measures to prevent and put an end to such uses.

The Lifetime Licence is understood to last for the period during which the Publisher operates the Software, and not for the lifetime of the User; it carries no guarantee of unlimited perpetuity of the Software or the Service.

The Publisher reserves all rights that are not expressly granted to you under these Terms. The grant of the Licence effects no transfer of ownership: the Software remains the property of the Publisher and of the relevant rights holders.

7. Fair use, prohibited conduct and anti-cheating

You undertake to make fair use of the Software and the Service in accordance with these Terms, applicable laws and regulations, and the rights of third parties. The Licence granted to you is limited to personal, non-commercial use, as defined in these Terms.

You shall in particular not use NotiChess to obtain assistance during an ongoing game, whether online (for example on Chess.com or Lichess) or in official over-the-board (OTB) competition, or in any manner contrary to fair-play rules, the terms of third-party platforms, or the regulations of chess federations. You are solely responsible for your use of the Software and the Service, and the Publisher disclaims all liability for any sanction imposed on you by a third party, a platform, or a federation as a result of such use.

The following uses are in particular prohibited:

• reselling, renting, sublicensing, lending or redistributing, whether free of charge or for consideration, the Software or all or part of the games database;
• circumventing, disabling or attempting to circumvent the technical protection measures of the Software or the Service;
• decompiling, disassembling or reverse-engineering the Software, save within the limits permitted by mandatory legal provisions, and in particular for interoperability purposes in accordance with Article L.122-6-1 of the French Intellectual Property Code;
• extracting or re-using a qualitatively or quantitatively substantial part of the games database;
• using the Service for unlawful purposes or to infringe the rights of third parties;
• disrupting, altering or compromising the security or proper functioning of the Service.

8. Plans, free trial and subscription

The Free Trial allows you to use the Service for a period of twenty-one (21) days. A payment card is mandatory and requested at sign-up, but no charge is made during the Free Trial. You may cancel at any time during this period, free of charge. If you do not cancel before the end of the Free Trial, the Subscription starts automatically at the end of the trial, according to the Plan you selected, and the corresponding charges begin. When you subscribe, the date on which the Free Trial ends and the Subscription begins is shown to you, and you may then manage or cancel your Subscription at any time from the Stripe customer portal accessible within the application. These details are summarised for you on a durable medium when your subscription is confirmed. Only one Free Trial is granted per User.

The Service is offered under three Plans: the Monthly Plan, the Annual Plan and the Lifetime Licence (Lifetime). The rates currently in force are promotional rates applied during the beta phase; they are shown, inclusive of all taxes (TTC) and in euros, on the Pricing page, which you should consult before subscribing. The applicable price is the one displayed at the time of subscription.

Subscription is carried out online: you select the Plan of your choice, then proceed with payment through our payment provider Stripe. Once payment is validated, a confirmation is sent to you and access to the subscribed Plan is activated.

9. Price and payment

The prices of the Plans and of the Lifetime Licence are stated in euros, all taxes included (TTC), on the Pricing page. The rates currently offered are promotional rates in force during the beta phase and are liable to change under the conditions set out in the section relating to price changes. The applicable price is the one displayed at the time of subscription.

Payment is made by bank card, through the payment service provider Stripe (Stripe Payments Europe). By subscribing to a renewable Plan (Monthly or Annual), you authorise the Publisher, through Stripe, to carry out the recurring debits corresponding to the term chosen. Billing takes place upon subscription, then at each renewal term. A payment receipt or proof of payment is made available to you.

In the event of a payment failure at a term date, a further debit attempt may be made. If payment remains impossible, access to the Service may be suspended, and the Subscription may be terminated in the absence of regularisation.

The terms governing price changes are set out in the section of these Terms relating to price changes.

10. Term, renewal and termination

The Monthly Plan is subscribed for a term of one month and renews for successive periods of one month. The Annual Plan is subscribed for a term of one year and renews by tacit renewal for successive periods of one year. In accordance with article L.215-1 of the French Consumer Code (loi Chatel), applicable to the Annual Plan, the Publisher informs you in writing, at the earliest three months and at the latest one month before the term, of your right not to renew the Subscription. Failing such information within the legal time limits, you may terminate the Subscription free of charge at any time from the renewal date, and any amounts wrongly collected after that date will be refunded to you.

You may terminate your Subscription at any time, online and easily, via the Stripe customer portal accessible from the application (termination “in three clicks”, article L.215-1-1 of the French Consumer Code).

Termination takes effect at the end of the current period: access to the Service is maintained until the end of the period already paid for, and no refund of the current period is due (Monthly and Annual Plans). The Lifetime Licence constitutes a one-off purchase, without renewal; the fourteen-day “satisfied or refunded” guarantee applicable to it is described in the section of these Terms relating to the right of withdrawal.

Termination at the Publisher's initiative, in particular in the event of a breach on your part, is governed by the section relating to suspension and termination for breach.

11. Right of withdrawal and refund

In accordance with the French Consumer Code, you have in principle a period of fourteen (14) days to withdraw from a distance contract, without having to give any reason. As the Service constitutes digital content and an online service performed immediately, you are informed that, by expressly requesting access to and use of the Service as soon as you subscribe, by giving your express consent to this immediate performance and by expressly waiving your right of withdrawal, you will no longer be able to exercise that right once the Service has been fully performed or access has effectively been opened (Article L.221-28 of the French Consumer Code); the Publisher sends you confirmation of this agreement on a durable medium. Failing such consent and waiver, the fourteen (14) day withdrawal period applies; in the event of withdrawal after a request for immediate performance, an amount corresponding to the service actually provided up to the withdrawal may remain due (Article L.221-25 of the French Consumer Code). This waiver applies only to the paid Plan actually performed; during the Free Trial, no sum is due and cancellation remains free and without charge.

The twenty-one (21) day Free Trial, the duration of which exceeds the fourteen (14) day withdrawal period, allows you to evaluate the Service under real conditions. Cancellation during the Free Trial is free, possible at any time and without charge: if you give up the Service before the end of the Free Trial, no charge is made and the Subscription does not start.

As regards the Lifetime Licence (Lifetime), the Publisher grants you a commercial “satisfaction or your money back” guarantee of fourteen (14) days from the payment of the Lifetime Licence. During this period, you may obtain a full refund of the Lifetime Licence upon simple request sent to contact@notichess.com, without having to give any reason. After this fourteen (14) day period, the purchase of the Lifetime Licence is final. The refund request is made by email to contact@notichess.com; the refund is carried out within fourteen (14) days following your request, using the same means of payment as the one used for the purchase, unless you expressly agree to another means.

For a monthly or annual Subscription cancelled during the course of a period, no refund of the period already elapsed is due: the Subscription remains active until the end of the current period already paid for, and no renewal takes place thereafter.

12. Changes to prices and plans

The Publisher reserves the right to change its prices, its Plans as well as the scope of the features of the Software and the Service, in particular as part of the ongoing development of NotiChess.

For ongoing Subscriptions, any price change applies only to the next renewal and after prior information given to the User. If you refuse the new pricing, you may cancel your Subscription before the relevant renewal date, under the conditions set out in these Terms; failing cancellation, the change is deemed accepted as from the renewal.

As regards the Lifetime Licence (Lifetime), the price you have paid is definitively acquired by you and is not affected by subsequent price changes. The functional scope of the Lifetime Licence may nevertheless evolve as part of the development of the Software.

13. Updates, availability and beta version

Throughout the term of your Subscription, the Publisher makes available to you the fixes and improvements to the Software. The Lifetime Licence includes updates to the Software, on the terms set out on the Pricing page.

The Software is currently offered as a BETA version. The Service is provided “as is” and “as available”. It may contain defects, and the Publisher does not warrant that it will operate uninterrupted or error-free. These provisions may not, however, deprive you of the benefit of the statutory guarantees of conformity provided for in Articles L.224-25-1 et seq. of the French Consumer Code.

The online features of the Service (Account, synchronisation with Chess.com and Lichess, updates to the games database) are provided without any service level commitment (no SLA). Interruptions are possible, in particular for maintenance operations, for technical reasons, or due to third-party providers such as Stripe, the hosting provider, or the Chess.com and Lichess platforms. The core of the Software remains usable offline, regardless of the availability of these online services.

The Publisher may modify, suspend or withdraw certain features. In the event of a substantial and lasting removal of an essential feature of an ongoing Subscription, you may terminate your Subscription and obtain a refund of the portion of the Subscription corresponding to the unused remaining period.

14. Intellectual property and third-party components

The Software, the NotiChess trademark, the interface, the texts, the games database and the content provided by the Publisher are protected and remain the exclusive property of the Publisher or its licensors. These Terms do not effect any transfer of intellectual property to you, but only the limited right of use set out in the Licence section.

The Software incorporates open-source components, including third-party analysis engines, governed by their own licences; those licences prevail for the components concerned. The chess piece icons are distributed under the CC BY-SA 3.0 licence (Cburnett). Details of these components and licences are set out on the Credits page (/credits).

Use of the Publisher's trademark and logos is prohibited without its prior written authorisation.

15. Protection of personal data

Personal data concerning you is processed by the Publisher in accordance with Regulation (EU) 2016/679 (GDPR) and the French Data Protection Act. The detailed terms of such processing (purposes, legal bases, retention periods, recipients) are set out in the privacy policy, available at /privacy, to which these Terms refer and of which it forms an integral part.

Only Account and Subscription data is hosted on the server side; payments are processed by Stripe (Stripe Payments Europe) acting as payment service provider. The chess data generated by the User (games, analyses) remains local on the User's machine and is not hosted by the Publisher.

You have, under the conditions provided by the GDPR, rights of access, rectification, erasure, restriction, objection and portability with respect to your personal data. You exercise these rights in accordance with the terms described in the privacy policy, through the contact form.

16. Legal warranties and liability

As a consumer, you benefit from the applicable legal warranties, and in particular the legal warranty of conformity for digital content and services provided for in Articles L.224-25-1 et seq. of the French Consumer Code. Nothing in these Terms may deprive you of the benefit of these legal warranties.

Beyond the legal warranties and the commercial warranty provided for the Lifetime Licence, the Service, currently in beta, is provided without any other warranty. The Publisher does not guarantee any result, and in particular no progress in chess, no completeness or absolute accuracy of the games database, nor the availability of third-party synchronisation services.

The Publisher is liable for direct and foreseeable damages resulting from a breach of its obligations, in accordance with the general law and the legal warranties. Within the limits permitted by law, its liability does not extend to indirect and unforeseeable damages. These limitations do not apply in the event of wilful misconduct, gross negligence or personal injury, and may not reduce your rights under the legal warranties.

It is your responsibility to regularly back up your local data and to verify the compatibility of your hardware with the Software; the Publisher may not, however, exclude its liability for any loss of data attributable to a breach on its part.

17. Suspension and termination for breach

The Publisher may suspend or terminate access to the Service in the event of a breach by the User of these Terms, in particular in the event of fraud, non-payment, unlawful use of the Software, cheating, sharing of the Account, infringement of the security or intellectual property rights of the Publisher or of third parties, or any other failure to comply with these Terms.

Save in cases of urgency, in particular in the event of fraud or a security breach, the Publisher shall first send the User a formal notice or a notification inviting the User to put an end to the breach or to remedy the situation within a reasonable period. Failing remedy of a serious breach, termination shall take effect by operation of law.

Suspension or termination results in the loss of access to the Service. No refund is due where termination is attributable to a breach by the User, subject to any amounts corresponding to services not provided the refund of which is required by law. Account data is retained or deleted in accordance with the privacy policy. These provisions are without prejudice to the statutory guarantees and to any right of the User to seek redress before the competent courts.

18. Amendment of these terms

The Publisher may amend these Terms at any time. Each version is dated, the date of last update appearing at the top of the document. Users are informed of substantial changes by an appropriate means, such as a notice on the website, within the Software or by email.

Amendments apply immediately to new subscriptions. For ongoing Subscriptions, they apply from the date indicated in the information communicated or, failing that, upon the next renewal. Continued use of the Service after the amendments take effect constitutes acceptance thereof.

In the event of a substantial change that is unfavourable to the User, the User may terminate the Subscription before the change takes effect, at no cost other than amounts already due for the current period.

19. Governing law and disputes

These Terms are governed by French law. This designation may not, however, deprive a User who is a consumer residing in another Member State of the European Union of the benefit of the mandatory protective provisions in force in their country of residence.

These Terms are drafted in French and translated into English. In the event of any discrepancy between the two versions, the French version prevails, without this depriving the User who is a consumer of the mandatory protective provisions of the law of their country of residence.

In the event of a dispute relating to the conclusion, interpretation or performance of these Terms, the User is invited first to send a complaint to the Publisher at contact@notichess.com, with a view to seeking an amicable resolution.

Failing an amicable resolution, the dispute falls within the jurisdiction of the courts having competence under the applicable legal rules. It is expressly recalled that the User who is a consumer may, at their choice, bring the matter before the court of the place of their domicile.
