General Terms of Use

Last updated: October 1, 2026 · Contact: contact@cartia.fr

1. Purpose

These general terms of use and sale (hereinafter the “Terms”) govern access to and use of the Cartia platform available at cartia.fr (hereinafter the “Service”), published by the publisher identified in the legal notice (hereinafter “Cartia”, “we”).

Rationalab is, like Cartia, a name and a business of Shams Factory. It is not a separate company: same legal entity, same SIRET. Only Chhaju Chakma, sole proprietor (entrepreneur individuel) (trade name Shams Factory), is the publisher of the Service, the contracting party and the holder of the legal obligations (billing, the Terms, DPA).

Cartia provides digital loyalty SaaS software for merchants: creation of a program (stamps or points), customer enrollment via QR code, a digital card viewable on a phone, scanning at the counter (web or the Cartia Counter app), a dashboard and related tools.

By creating an account or using the Service, the merchant (hereinafter the “Customer”, “you”) accepts these Terms. If you do not accept these terms, you must not use the Service.

2. Definitions

3. Account and access

Registration requires accurate and up-to-date information (identity, email, organization details). You are responsible for the confidentiality of your credentials and for the activity carried out from your Account.

You must notify Cartia without delay of any suspected unauthorized use (contact@cartia.fr). Cartia may suspend or restrict an Account in the event of suspected abuse, non-payment, breach of the Terms or a risk to the security of the Service.

The Service is intended for professionals. You warrant that you have the authority necessary to bind the Organization concerned.

4. Description of the Service

Depending on the Plan subscribed, the Service may include, in particular:

Digital card and Wallet. End Members add their card through the QR flow, with direct addition to Apple Wallet and Google Wallet. The Service includes the generation and updating of these passes within the limits of technical constraints and of the terms of the Apple and Google platforms.

5. Plans, pricing and trial

Unless otherwise indicated at the time of the order, the Plans are as follows:

The prices, quotas and inclusions displayed in the Service or on the pricing page prevail in the event of any discrepancy with older marketing material. Cartia may change the Plans; price changes applicable to existing subscriptions are communicated within a reasonable time before they take effect.

At the end of a trial that is not converted, or upon expiration / termination of a paid Plan, access to paid features may be restricted (including scanning), in accordance with the Service’s entitlement rules.

6. Payment and billing (Stripe)

Paid Plans are billed through the payment provider Stripe. By subscribing, you accept the processing of your payment data by Stripe under its own terms. Cartia does not store full bank card numbers.

Unless otherwise stated, subscriptions renew automatically at the end of each period until terminated or until the Plan is changed through the flows offered in the Service. In the event of a payment failure, Cartia may suspend all or part of the Service after reasonable notice.

The amounts displayed are the amounts due, in euros, with no tax added at checkout (Free €0, Pro €29.90 / month, Business €59.90 / month, additional location €10 / month). VAT not applicable, article 293 B of the French General Tax Code (CGI).

Subscription pause. The Account holder may pause a paid Plan from the dashboard, with or without a resumption date. During the pause, no charge is made and the Service is suspended (counter visits, new sign-ups, campaigns); data and cards already installed are kept. Time already paid for and not used on the day the pause begins is set aside: it is not refunded, but is returned on resumption by postponing the next due date, provided the pause lasted at least 7 days. A shorter pause has no effect on the due date. A pause lasts 12 months at most: if the subscription is not resumed, and after a warning sent at least 30 days beforehand, the subscription is terminated and the time set aside is lost. The same applies if the subscription is terminated during a pause.

7. Customer’s obligations (merchant)

You undertake in particular to:

Cartia acts as a technical provider. You are responsible for the content of your program, your materials (posters, QR codes) and the commitments made to your customers.

8. Data and privacy

The processing of personal data is described in the privacy policy. For End Members’ data collected as part of your program, you act in principle as data controller; Cartia acts as a technical data processor for the hosting and operation of the Service, under the data processing agreement (DPA), except where Cartia alone determines the purposes (e.g. billing of your SaaS subscription, platform security). Application data is hosted in Germany (Hetzner Cloud, EU).

9. Availability, maintenance and changes

Cartia endeavors to provide reasonable availability of the Service. Interruptions may occur (maintenance, incidents, force majeure, third-party dependencies). No 100% availability is guaranteed.

Cartia may change the Service (features, interfaces, API) to improve security, compliance or the product experience. Substantial changes likely to adversely affect day-to-day use are communicated where possible.

10. Intellectual property

The Service, its software, trademarks, interfaces and documentation remain the property of Cartia or its licensors. No transfer of rights is granted beyond the limited, non-exclusive, non-transferable license of use necessary to use the Service for the duration of the contract.

You retain your rights in your content (logo, program texts, data you upload). You grant Cartia a limited license to host and process it solely for the purpose of providing the Service.

11. Liability

The Service is provided “as is” for professional use. To the extent permitted by law, Cartia cannot be held liable for indirect damages (loss of revenue, of clientele, of data not attributable to Cartia, reputational harm) or for business decisions made on the basis of the dashboard indicators.

Cartia’s total liability under these Terms, for one event or a series of related events, is limited, except in the case of gross negligence (faute lourde) or willful misconduct (dol), to the amount actually paid by you to Cartia under the relevant Plan during the twelve (12) months preceding the triggering event - or to zero euros if you are only on the Free Plan.

You remain solely responsible for the rewards promised to your End Members and for honoring them in the shop.

12. Term, termination and effects

The contract takes effect upon creation of the Account and continues for the duration of the chosen Plan. You may stop using the Service or request closure of your Account by contacting contact@cartia.fr (or through the flows available in the product, where applicable).

Cartia may terminate or suspend the Service in the event of a serious breach that is not remedied, non-payment, unlawful use or a risk to the platform. Upon termination, access to the Service ends; data is kept or deleted in accordance with the privacy policy and legal obligations.

13. Changes to the Terms

Cartia may modify these Terms. The version in force is published on this page with its update date. For Customers with an active Account, material changes are notified by reasonable means (email or notice in the Service). Continued use after the changes take effect constitutes acceptance, unless the law provides otherwise.

14. Governing law and disputes

These Terms are governed by French law. In the event of a dispute, and failing an amicable settlement, jurisdiction is vested in the competent French courts, subject to the applicable rules of public policy.
