Your research data.
This describes the current beta. Contact us before entering information you do not want stored in your account or browser.
Account data
Accounts use Supabase authentication. Your email address, display name, verification status, card watchlist, coverage requests and beta-access request/status are stored with the service. Authentication cookies keep you signed in. Beta requests are reviewed by the operator.
Confirmation and password-reset emails are delivered through Resend, which processes the recipient address, email content and delivery events. We use delivery records to troubleshoot email failures. The website is hosted on Vercel, with DNS managed by Cloudflare.
Browser notebooks
Slab observations and saved grading scenarios are stored in this browser’s local storage, separately from your account watchlist. Clearing browser data can remove them. Export a notebook backup before changing devices. Imported files are processed in your browser; an import does not verify that a sale matches your card.
Research services
Card searches and coverage requests are sent to our application and database. Operational errors may be logged for troubleshooting. Where AI interpretation is enabled, submitting a question sends the question and relevant research context to the configured AI service. The interface shows when that feature is unavailable.
Contact, correction or deletion
You can remove cards from your watchlist and entries from your notebook. For account-data questions, corrections or deletion requests, contact the beta operator. Emailing support shares the content you choose to send; do not include passwords or API keys.
