Privacy Policy

Last updated: August 2026

What we collect

If you create an account, we store your email address, a securely hashed password, and (optionally) a display name. If you use the collection-tracking features, we store the cards and prices you choose to track, associated with your account. We use a single session cookie to keep you signed in — it contains a random token, not your account details. If you submit a community listing, we also remember your last-used shipping/currency/marketplace choices on your account, so the form is pre-filled next time. If you attach photos to a listing (see our Terms of Service), we re-encode them on upload and strip embedded metadata (such as EXIF location data) before storing them — they're shown publicly next to your listing.

What we don't do

We don't sell or share your personal data with third parties, run advertising trackers, or use analytics that identify individual visitors. Card pricing data is fetched from third-party marketplaces (eBay, CardTrader) using server-to-server requests that don't include any of your personal information.

Data retention & deletion

You can delete your account and associated data at any time from account settings. Contact us at the email below if you'd like your data removed and can't access the app.
