What YGOPrices stores about you

Browsing YGOPrices without signing in is anonymous. We do not build a profile of unauthenticated visitors and we do not use third-party ad networks.

When you sign in, we store a small profile row (display name, avatar preference, preferred currency), the collection you record on /collection, cards you save on /watchlist, and decks you build on /decks. These rows are stored in our Supabase project and protected by Row Level Security so only your account can read or edit them.

Cookies and sessions

YGOPrices uses first-party cookies to keep you signed in and to remember the theme you picked. We do not use third-party advertising cookies. Session cookies are marked HttpOnly and SameSite so a link from another site can never impersonate you.

Analytics

We run anonymous page-view counts through Vercel Web Analytics. If Google Analytics is enabled for YGOPrices it is set to IP anonymisation and used only for aggregate site statistics.

Affiliate links

The Find on eBay buttons across YGOPrices are eBay Partner Network affiliate links. If you buy through one we may earn a commission at no cost to you. eBay is the party you transact with; we do not see your purchase details.

Emails

The only email YGOPrices sends today is the magic-link sign-in email issued by Supabase Auth. We do not run a marketing mailing list.

Deleting your account

You can delete your account from /settings. The deletion wipes your collection, watchlist, decks and profile from our database. The underlying Supabase auth user identity is retained if the account is shared with another Collector Network site.
