Data used by the Cristal Memoria connector

Connector information updated 9 November 2026. Read this together with the Cristal Memoria privacy policy, which identifies the controller, service providers, retention practices, deletion process and privacy contact.

What you authorize

The connection uses your Cristal Memoria email and a one-time email code to authenticate your account. You then authorize access to your cloud decks, notes, card fields, tags, card scheduling state, note models, review statistics and review settings. Requested operations can create, change or delete these collection items. The connector cannot answer reviews, award rewards, access your village or make purchases.

Data shared with the assistant

The card contents and collection information returned by tools are sent to the assistant in which you use the connection, such as Claude, operated by Anthropic, or ChatGPT, operated by OpenAI. That service processes the information under its own terms, privacy policy and your account settings. Only request access to content you want to share with that assistant.

Video links

When you ask for cards from a video, the link you give is sent to the Cristal Memoria server, which reads the public page and its subtitles. For some sites, such as YouTube, the link is passed to a transcript provider (Supadata) that returns the public captions. Only the link is shared, never your account or cards. The transcript is returned to the assistant and is not stored by Cristal Memoria; a daily count per account limits abuse.

Connection records and previews

Cristal Memoria stores client registration information, temporary sign-in records, hashed OAuth tokens and the proposed card operations needed to operate the connection. An access token is valid for one hour; refresh tokens rotate and expire after 60 days. A prepared proposal expires after five minutes. Expiration prevents use; it does not imply immediate erasure of every stored record. Applied changes become part of the synced collection, with a transaction receipt.

Control and deletion

You can remove the connection in the assistant's settings. The service provides an OAuth revocation endpoint, and account deletion removes the associated connector records. For access or deletion requests, contact hello@cristal-memoria.com. The general privacy policy explains retention exceptions, backups and your rights.
