Privacy policy
Last updated November 11, 2026
This is the privacy policy for Cardboard Catalogue, a site for scanning, identifying and organizing sports cards. It explains in plain language what we collect, why, who helps us run the site, and how you can delete your data.
Your account
To use the catalog you sign in with an email and password, or with Google or Apple. We store your email address, a display name, and anything you add to your collector profile (such as a birthday or your first card). If you sign in with Google or Apple, that company tells us your email and name; we never see your password for those services.
Card photos you upload
The front and back scans you upload are stored privately in your account. Other collectors can't see them. We keep them until you delete the card or your account.
Identification and value estimates
To identify a card, we send its scan to AI image services (through Lovable's AI service and the CardSight card-recognition service). They return a suggested player, set, year, number and parallel. We also use AI to describe visible condition and to estimate values from recent sales. These are estimates, not professional grades or appraisals. We save the results, your corrections, and your value history with your cards.
Sharing scans with the shared catalog (optional, off by default)
If you turn on Contribute my front scans in Settings, a clear front scan of a card you own can be copied into the shared catalog, where other collectors see it as the reference picture for that checklist slot. Back scans and your account details are never shared. Turning this off stops future contributions; images already contributed stay in the catalog without your name attached.
eBay images and listings
For checklist slots that have no collector scan, we may show a photo from a live eBay listing to help you browse that card on eBay. These pictures are loaded directly from eBay, are re-checked at least every 6 hours, and are removed when the listing is no longer available. A "View on eBay" link opens the listing on eBay's site. If you click it, eBay's own privacy policy applies there.
Other services we use
- Lovable Cloud hosts the site, your account and your stored scans.
- Google and Apple, if you choose them to sign in.
- Google Fonts, which supplies the lettering on the site. Your browser loads it from Google.
- Public checklist and photo sources (such as Trading Card Database and Wikimedia Commons). We look these up to build checklists and show player photos. Your personal data isn't sent to them.
- Google Drive, only if you connect it yourself to import scans. We can only see the files you pick.
Site analytics
We use Lovable's built-in visitor analytics to understand how the site is used. It uses no cookies, stores nothing on your device, doesn't keep IP addresses and doesn't identify visitors. Lovable collects this data for us. Lovable's privacy policy explains how it handles it.
It records the pages visited, where visitors came from, their country, browser, operating system and device type, how long they stay, how fast pages load, errors, which buttons and links are clicked, and a few events from the app itself (for example, that a scan was submitted). This is recorded for every visitor. Detailed data is kept for 90 days and daily summaries for a year.
The site also stores your sign-in session in your browser so you stay signed in.
What we don't do
We don't sell your personal information, and we don't use your scans for advertising.
Deleting your account
You can delete your account at any time in Settings → Delete account. This permanently removes your sign-in, profile, scans, collection, values and any Google Drive connection. Shared checklists, and front scans you already chose to contribute to the shared catalog, remain in the catalog.
Questions
If you have a question about this policy or your data, contact the site owner through the contact details provided where you found Cardboard Catalogue. We may update this policy as the site changes; the date at the top shows the latest version.
