Privacy Policy

Who we are

MousséCristalCorp, 61 rue de Lyon, 75012 Paris, France, is responsible for your data (hello@cristal-memoria.com). We do not sell your data, show no ads and do not track you across other apps.

What we collect and why

• Account and study: email, cards, media, reviews, settings and village, to run the app and sync it.
• Community: profile, friends and shared decks, visible to the people you choose.
• The Sage: the text of the cards you ask about is sent to our AI provider to write the answer. It is not used to train AI models.
• Voice: the text to read, or your voice after you allow the microphone, goes to the voice service.
• Purchases: Apple handles payment. We only receive the transaction, to credit your account.
• Usage and crashes: events tied to a random install number, never to your cards, name or email. You can turn them off in Preferences.

Who processes it

Only the providers we need: hosting in the EU, network security, email delivery, the AI and voice services, and Apple for purchases. Each is bound by contract to use the data only for us. Transfers outside the EU are covered by the European Commission’s safeguards. If the service is sold or merged, the data moves with it, under this policy.

We protect the data with strict technical and organizational measures, but no system is fully secure. If we suspect an attack, we may suspend part of the service to protect your account.

How long

Until you delete your account, or after two years without use, when we delete or anonymize it after an email warning. We keep what we need to meet legal obligations, settle disputes and enforce our terms, such as the record of a ban. Backups are erased on their normal cycle, and decks you shared may remain with the players who copied them. Purchase records are kept ten years, as accounting law requires. We may publish statistics that identify no one, such as the total number of reviews.

Delete your account

In the app: Settings > Cristal ID > More options > Delete my Cristal ID. Or write to hello@cristal-memoria.com. Deleting the account does not cancel an Apple subscription: cancel it in your Apple Account settings.

Your rights

Access, correction, deletion, portability and objection: write to hello@cristal-memoria.com. You can also complain to the CNIL. The app is not meant for children under 13.
