Privacy

What we collect

Your email address, name, optional profile photo and a password hash when you create an account; what you add to ChaseCharts: your collection, watchlist, wants, fee settings, showcase settings and email and alert preferences; the searches you run in the card catalog; which page you first landed on and the site that sent you; and server logs (IP address, browser, pages requested) kept for security and debugging. If you subscribe to Pro, Stripe collects your payment details; we never see your card number, only a customer id and subscription status.

Card photos: when you scan a card, import cards from a photo or run Pro's condition check, the image is sent to Anthropic (the Claude AI service) to read the card's name and number (for the condition check, its corners, edges and surface), and a scan is compared with our card images. We do not keep the photo; Anthropic processes it under its commercial terms, which do not allow training on it. When you add scanned cards to your collection, we keep a record of which card the scanner suggested and which card you kept (not the photo, and not tied to your account), to measure and improve the scanner.

In the iPhone app: if you turn on alerts, your phone's notification token, so Apple can deliver them; and your App Store country, so the app knows whether Pro can be bought in it (kept only in a cookie on the phone). The notification token is removed when you sign out or delete your account.

What we use it for

To run the service (signing you in, valuing your collection, applying your fees, finding listings for your wants), to send emails and alerts you asked for (password resets, email confirmation, the digest and alerts you turned on) and to bill Pro subscriptions. A showcase is public only if you turn it on. We do not sell personal data. We advertise on X, and measure those ads as described under Cookies.

Who processes it

Stripe (payments), Resend (email delivery), Anthropic (reading card photos), Apple (delivering app alerts), Cloudflare (network and cookieless visit counts), X (measuring our ads, below) and our hosting provider. Each processes data only to provide its service to us. Market data providers never receive your personal data.

Cookies

ChaseCharts uses a session cookie to keep you signed in, and small first-party cookies for a partner or invite link you arrived through (30 days), the page you first landed on (90 days) and, in the app, your App Store country. On the website, X's conversion pixel counts visits from our X ads and may set its own cookies; when you sign up or start Pro we tell X, with your email address hashed (scrambled one way, so X can match it to an X account but cannot read it) and, if you came from an X ad, its click id. None of this happens in the iPhone app, or in a browser that sends Global Privacy Control.

Your choices

Turn the digest off under Account. To delete your account and its data, use Delete account at the foot of the Account page: it is deleted at once and any Pro subscription is canceled. You can also email hello@chasecharts.com from the address on the account and we delete it within 30 days. Either way we keep only records we must keep for tax or fraud purposes.
