Terms of Use

Who we are

Cristal Memoria is provided by MousséCristalCorp, 61 rue de Lyon, 75012 Paris, France (hello@cristal-memoria.com). On iOS, Apple’s standard End User License Agreement also applies. If you are under 15, a parent must agree to these terms and to any purchase.

Purchases

The app is free. Optional purchases are billed by Apple:

• Gems speed up the village and buy cosmetic items. They are a license to use content in the app, with no monetary value, and cannot be exchanged or transferred.
• Cristal Premium (monthly or yearly) unlocks the Sage. It renews automatically unless canceled at least 24 hours before the end of the period, in your Apple Account settings.

Purchases need a Cristal ID. Items are delivered at once: by confirming, you ask for immediate delivery and lose the right of withdrawal, as the law allows for digital content. We may adjust the prices and effects of in-game items, and change the Premium price for future periods after notice, as Apple’s rules require. An obvious pricing error may be corrected and the order canceled. Refunds are handled by Apple; if a purchase is refunded, we may remove the matching items or Premium. Items end when the account is deleted or closed for a breach of these terms. No money or compensation is owed for unused items when an account is closed or the service ends. Items bought outside the app, for example from third-party sellers, may be removed.

Study content and AI

Cristal Memoria is a study tool, not medical or professional advice, and does not guarantee any exam result. You are responsible for your decks. The Sage’s answers come from AI and can be wrong: check them. Anki is a trademark of its owners; Cristal Memoria is not affiliated with it.

To keep the service affordable for everyone, we may set fair-use limits on AI and storage, including for Cristal Premium.

Your account

Your account, village and items are licensed to you, not sold: you may not sell, rent, give away or share them. You are responsible for everything done with your account, including purchases made by a child on your device. We may change or reclaim a username.

Your content and the community

You keep your content and must hold the rights to it. You allow us to store, convert and share it as needed for the features you use; copies that other players already took of a deck you shared may remain. Do not put anyone’s health or personal data in your cards. Ideas and suggestions you send us may be used freely, without payment. Content that is hateful, harassing, sexual, violent, illegal or that infringes someone else’s rights is forbidden.

Shared decks and player profiles can be reported, and players can be blocked. Abusive or false reports are themselves sanctioned. We act on reports promptly, normally within 24 hours, and may remove any content or close any account that breaks these rules.

Cheating, exploiting bugs, automating the app, scraping or copying its content, reverse engineering it beyond what the law allows, using it to build a competing product, attacking or overloading the service, and selling or sharing accounts are forbidden. We may then cancel the gains, reset the progress or close the account. If you think a sanction is unjustified, write to hello@cristal-memoria.com and we will review it. We are not a party to disputes between players. Found a security issue? Write to hello@cristal-memoria.com.

We host content without checking it beforehand. To report illegal content or a copyright infringement, use “Report” or write to hello@cristal-memoria.com with the link and the reason: we remove it quickly once notified.

Liability

The app is provided as is. To the extent permitted by law, we are not liable for indirect damage or for lost data or progress, and we do not guarantee backups; keep your own. Our total liability is limited to what you paid in the six months before the claim. This does not limit your rights as a consumer.

Changes and law

We may change, suspend or end any feature, or the service itself, with reasonable notice for paid features; an account unused for two years may be deleted after an email warning. We may transfer these terms to a company that takes over the service. We are not liable for events beyond our control. We may update these terms and will announce important changes in the app. You can stop using the app and delete your account at any time (Settings > Cristal ID > More options). French law applies, without removing the protections of your country of residence.
