Cardslot
Terms and Conditions

Last updated: 2026-08-14

Who we are

Cardslot is published and operated by Aurélien Ribon, an individual developer (entrepreneur individuel) trading under the brand "Auline". We answer messages sent to contact@cardslot.app; that address is the means of rapid contact for anything concerning the Application, these Terms, a purchase or a complaint, and our postal address and registration details are provided free of charge on request at that same address.

1. Acceptance of these Terms

These Terms and Conditions ("Terms") form a binding agreement between you ("you" or "user") and Aurélien Ribon, the publisher identified above, an individual developer (entrepreneur individuel) trading under the brand "Auline" ("we", "our" or "us"), regarding your use of the Cardslot mobile application ("Application"). The Application is distributed through the Apple App Store (iOS) and Google Play (Android). By downloading, installing or using the Application, you accept these Terms in full. If you do not accept them, please do not use the Application and remove it from your device. The Application is intended for users aged 15 or over, or the age of digital consent in your country of residence if that age is higher. It is not directed at children, and we do not knowingly process data relating to a child below that age. If you are below that age, you may use the Application only under the responsibility of a parent or legal guardian, who accepts these Terms on your behalf.

2. What the Application does

The Application lets you browse games available on the European Nintendo eShop, look at their prices and current discounts, search the catalogue, follow the games you are interested in, and set up alerts about price changes on those games. The Application is an independent price-watching tool. It is not a shop: no game, key, code or digital content is ever sold, resold or delivered through the Application. Purchases of games are made exclusively on the Nintendo eShop or on Nintendo's own websites, under Nintendo's own terms, and we are not a party to those transactions. The Application may open Nintendo's website in your device's browser so you can complete a purchase there.

3. Licence to use the Application

We grant you a personal, non-exclusive, non-transferable, non-sublicensable licence, revocable in the cases set out in section 15, to install and use the Application on devices you own or control, for your own personal, non-commercial use. All rights not expressly granted are reserved. You may not copy, modify, translate, resell, rent, sublicense or create derivative works of the Application, nor attempt to decompile, reverse-engineer or extract its source code, except to the extent such restrictions are prohibited by applicable law. This licence does not transfer any ownership of the Application to you.

On iOS, the licence to use the Application is governed by Apple's Licensed Application End User License Agreement (the standard EULA), which the Application links to from its settings; these Terms then govern your use of our service and of the information it provides. The licence granted above applies to installations from Google Play. Section 18 sets out additional terms that apply to installations from the Apple App Store.

4. The full version, purchases and refunds

4.1. What is paid and what is not

The Application is free to download and free to use for its core purpose: searching the catalogue, reading prices and discounts, and following a game. An optional one-time purchase, called the "full version", unlocks additional features of the Application. What the full version includes is described in the Application at the moment of purchase; it may only be changed under the conditions of section 7. Features already unlocked by the full version remain unlocked on the store account used to buy it, for as long as the Application is distributed.

4.2. How the purchase is processed

The full version is sold as an in-app purchase processed entirely by Apple (App Store) or Google (Google Play) through your store account, and managed on our side with the help of RevenueCat. The purchase is concluded with the store that processes it (Apple Distribution International Ltd. for the App Store, Google for Google Play), which acts as seller and issues the receipt; we are the supplier of the digital content that is unlocked. Requests relating to the payment itself, such as an invoice or a refund, go to the store; requests relating to the content of the full version go to us at contact@cardslot.app. The price shown at the moment of purchase, in your store's currency, is the price that applies. We never receive, see or store your payment details. By confirming the purchase on your store's confirmation screen, you expressly request that the full version be supplied to you immediately (see section 4.5).

4.3. Restoring a purchase

The full version is attached to the store account used to buy it. If you reinstall the Application or install it on another device signed in with the same store account, you can restore the purchase from within the Application, without paying again. Restoring requires an internet connection and a working connection to the store.

4.4. Refunds

Refunds for in-app purchases are handled exclusively by the store that processed the payment (Apple or Google), according to that store's own policy. We cannot issue, promise or accelerate a refund, and we have no access to your payment method or to your store account. The only purchase information available to us, through RevenueCat, is whether this installation owns the full version and whether that purchase has been revoked. Refund requests must be addressed directly to Apple or Google. This is without prejudice to your statutory rights as a consumer, in particular the right of withdrawal described in section 4.5, the legal guarantee of conformity described in section 12, and the refund we owe you under section 7 if we degrade or discontinue the full version, all of which you may invoke against us directly.

4.5. Right of withdrawal

If you are a consumer in the European Union, you have a period of 14 days from the conclusion of the purchase to withdraw from it without giving any reason and without penalty. Because the full version is unlocked immediately, when you confirm the purchase you expressly ask us to begin performance at once and you expressly acknowledge that you lose your right of withdrawal once the full version has been fully supplied to you. If you have not yet received the full version, you may exercise the right of withdrawal by sending an unambiguous statement to contact@cardslot.app, using if you wish the model form below. In practice, the reimbursement is executed by the store that took the payment, and we will direct you to the relevant procedure.

5. Price information: accuracy and limits

5.1. Prices are indicative

All prices, discounts, discount percentages, promotion end dates, release dates, artwork, publishers, categories, edition names, popularity rankings and other catalogue information shown in the Application are provided for information only. They are estimates of what the eShop shows, not an offer, not a quotation and not a commitment by us or by anyone else. Nothing displayed in the Application creates a right to buy a game at the price shown.

5.2. Where the information comes from

Catalogue and price information comes from information that Nintendo makes publicly available about its European eShop. We do not create this information, we do not control it, and we cannot correct it at the source. Any of these sources may change, become unavailable, return incomplete or inconsistent data, or stop being accessible at any time and without notice.

5.3. Prices are a euro-zone reference, not your local price

Price information is collected using a single euro-zone reference shop and is displayed in euros. The price actually charged to you depends on the country of your Nintendo account, on the currency of that shop, on local taxes, and on promotions that may differ from one country to another. The amount you see in the Application may therefore differ from the amount you are charged, even at the same moment.

5.4. Errors, delays and stale data

Prices and promotions change constantly, and the Application works from a catalogue snapshot that is refreshed periodically. Information shown may be out of date, wrong, incomplete, missing, or attached to the wrong edition of a game. A promotion may end earlier than announced, a discount may never start, and a game may disappear from the catalogue.

5.5. Only the eShop is authoritative

The only authoritative price is the one displayed on the Nintendo eShop, in your own account's shop, at the moment you complete the purchase. You must check it there before buying, and the Application provides a link to the eShop page of each game for that purpose.

6. Alerts and notifications

Alert delivery is being rolled out progressively: the Application may ask for the notification permission and register your device before any alert is actually sent, alerts may not be active on your platform at the time you install the Application, and no alert may be sent at all for a given period. At the date of these Terms, no alert is sent yet, as our Privacy Policy also states. Alerts are a convenience feature offered on a best-effort basis. We give no guarantee that an alert will be generated, that it will be delivered, that it will be delivered on time, that it will be delivered at all for a given game or a given promotion, or that its content will be accurate. Delivery depends on factors outside our control, including your operating system's notification permissions and settings, Apple's and Google's push services, battery-saving and background-activity restrictions, and network availability. To limit noise, the number and timing of alerts may be capped, and some alerts may be grouped, delayed or dropped. Every alert is about a game you chose to follow — a price drop, or a reminder the day before a discount ends — and both are enabled by default. You can turn either off inside the Application, and all of them off in your device settings.

7. Availability, changes and interruptions

The Application and its server are provided without any uptime, continuity or availability commitment. Features may be added, changed, limited or removed, subject to section 4.1 for features already unlocked by the full version, and only for a valid reason: technical adaptation of the Application, security, the unavailability or the change of a third-party source we depend on, or a legal obligation. Such changes are made at no additional cost to you. Where a change negatively affects your access to, or your use of, the full version you paid for, we will inform you in advance on this page and in the Application, and you may end your use of the full version at no cost and obtain a refund of the price you paid, in proportion to the part of the full version that can no longer be provided as described; we will arrange that refund by the means available to us, including by directing the store that took the payment to process it. The same applies if we permanently discontinue the Application.

Some features require an active internet connection; we are not responsible if the Application does not work fully because of a lack of connectivity, an exhausted data allowance, or a device or operating system that is not supported. If you use the Application over mobile data, your carrier's charges, including roaming charges, are your responsibility, and we assume you have the bill payer's permission if you are not the bill payer. We may require you to install an update in order to keep using the Application, and we do not guarantee that the Application will remain compatible with future versions of your device's operating system.

8. Your data

The Application does not use accounts, passwords or email addresses. Each installation generates a random installation identifier, which is sent with every request to our server and is used to keep a server-side copy of the games you follow, to register your device for notifications (push token, platform, application language and device time zone), to record whether the full version has been purchased, and in our server logs. Our Privacy Policy, published at /privacy.html, lists everything that is sent, what our server logs record, where the data is stored, how long it is kept and how you can exercise your rights.

That server-side copy belongs to the installation, not to you: it is not shared between two devices, and as a rule it is not restored when you uninstall and reinstall the Application, because a reinstall normally starts from a new installation identifier and an empty list. The exception is your device's own system backup: if it is enabled, Apple or Google may keep a copy of the Application's local data (including its installation identifier) and restore it when you reinstall, in which case the server-side copy comes back with it. Only the full version is restored through your store account in every case, as described in section 4.3. Uninstalling the Application removes the data held on your device, but it does not delete the copy held on our server; to have that copy deleted, send us your installation identifier at contact@cardslot.app. It is displayed in the Application, in Settings, just below the contact row, and one tap copies it.

The Privacy Policy is an information notice, not a contract: it tells you how your data is processed and on what legal basis. Where we rely on your consent, it is asked for separately in the Application or by your operating system, and you can withdraw it at any time.

9. Intellectual property

The Application, its source code, its interface, its design, its texts and its own visual assets are protected by copyright and remain our property. Game titles, cover art, screenshots, descriptions, logos and trademarks shown in the Application belong to their respective owners, including Nintendo and the publishers of the games listed. They are displayed for the sole purpose of identifying the game concerned and helping you find it on the eShop. Images are loaded directly from the sources that host them and are not re-hosted by us. If you own rights in content shown in the Application and object to its display, write to contact@cardslot.app and we will act on your request.

10. No affiliation with Nintendo

The Application is an independent project. It is not affiliated with, associated with, authorised by, endorsed by, sponsored by, or in any way officially connected with Nintendo Co., Ltd., Nintendo of Europe, or any of their subsidiaries or affiliates. "Nintendo", "Nintendo Switch", "Nintendo eShop" and all related names, marks, logos and images are trademarks or registered trademarks of their respective owners, used here for identification purposes only. All game titles and related content are the property of their respective owners. No endorsement of the Application by any of them is claimed or implied.

11. Acceptable use

You agree to use the Application lawfully and reasonably. In particular, you agree not to: We may apply technical limits, including request rate limits and daily caps, to keep the service available for everyone.

12. Legal guarantee of conformity

The full version and the free features of the Application are digital content within the meaning of Directive (EU) 2019/770. We owe you the legal guarantee of conformity provided by articles L.224-25-12 and following of the French code de la consommation, which applies both to the full version you paid for and to the features supplied free of charge.

This means that the Application must correspond to its description, be fit for the purpose for which digital content of the same type is ordinarily used, and be supplied with the updates needed to keep it in conformity. If the Application is not in conformity, you may require it to be brought into conformity free of charge, and, under the conditions of articles L.224-25-19 and following of the same code, obtain a reduction of the price or the termination of the contract with a refund. The guarantee applies for two years from supply where the digital content is supplied in a single act, and for the whole supply period where it is supplied continuously. It is independent of any commercial commitment we may make, it does not depend on any store's own refund policy, and it cannot be waived: any clause of these Terms that would set it aside is void. To invoke it, write to us at contact@cardslot.app.

13. Disclaimer and limitation of liability

Subject to the legal guarantee of conformity set out in section 12 and to any other mandatory right you have as a consumer, and to the fullest extent permitted by law, the Application is provided without additional warranty as to accuracy, completeness, timeliness, or uninterrupted or error-free operation, for the factual reasons explained in section 5.

If you use the Application otherwise than as a consumer, that is to say for the purposes of your trade, business, craft or profession, we accept no liability for indirect or consequential loss or loss of opportunity, and our total liability is limited to the amount you paid for the full version of the Application, if any.

If you are a consumer, that limitation does not apply to you: we are liable, under the conditions of the general law, for the direct and foreseeable damage caused by a failure of our own obligations. Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, including liability for death or personal injury caused by negligence, for fraud, or under mandatory consumer-protection rules.

14. Third-party services

The Application relies on third-party services that have their own terms and privacy policies, including the Apple App Store and Google Play (distribution, payment and push delivery), RevenueCat (purchase management), and Amazon Web Services and OVH (hosting and infrastructure). Your use of those services through the Application is subject to their respective terms, and we are not responsible for them.

Cover art and screenshots are displayed from the addresses published by their host, so your device contacts that host directly when an image is shown, and opening an eShop link takes you to Nintendo's own website. Those sites are governed by their own terms, which we do not control. More generally, links opened from the Application lead to sites we do not control.

15. Termination

You may stop using the Application at any time by uninstalling it. We may suspend or terminate your access to the Application or its server, in whole or in part, in the event of a serious or repeated breach of section 11. Except where the security or the availability of the service is immediately at risk, in which case we may suspend access straight away, we will first notify you in the Application where that is feasible (we hold no email address for you, as section 8 explains), tell you what we hold against you, and give you the opportunity to put an end to the breach. We may also terminate if we discontinue the Application, under the conditions of section 7.

Upon termination, the licence granted in section 3 ends and you must stop using the Application. Sections concerning intellectual property, disclaimers, limitation of liability and governing law survive termination. If we terminate your access without any fault on your part, or if we discontinue the Application, you may obtain a refund of the full version under the conditions of section 7; where your access is terminated for a serious breach of section 11, no refund is due. Refunds processed by the store are handled as described in section 4.4.

16. Governing law and disputes

These Terms are governed by French law, without prejudice to the mandatory protective provisions of the law of the country where you have your habitual residence if you are a consumer in the European Union. We encourage you to contact us first at contact@cardslot.app so we can try to resolve any dispute amicably.

If your written complaint to us has not been resolved within two months, and you are a consumer residing in the European Union, you may refer the dispute free of charge to a consumer mediation body competent in your country of residence; write to us at contact@cardslot.app and we will tell you which body is competent for us. Failing an amicable settlement, the dispute will be brought before the competent courts under the applicable rules of jurisdiction.

17. Changes to these Terms

We may modify these Terms from time to time, and only for a valid reason: a change to the Application, a change to a service it relies on, or a change to applicable law. Changes apply only for the future; they never apply retroactively to a purchase already made. The updated Terms are published on this page with a new date. Where a change materially affects the full version you paid for, we will announce it on this page and in the Application at least 30 days before it takes effect. If you do not accept a change, you may stop using the Application and uninstall it, and where the change degrades the full version you paid for you may obtain the refund provided in section 7.

18. Additional terms for the Apple App Store

The following applies if you installed the Application from the Apple App Store, without prejudice to your mandatory rights as a consumer and to the legal guarantee of conformity set out in section 12:
