Privacy Policy
Last updated: May 2026
At OnePieceCardValue ("we", "us", "our"), we take your privacy seriously. This Privacy Policy explains how we collect, use, and protect your information when you use our website at onepiececardvalue.com (the "Service").
1. Information we collect
1.1 Analytics data
We use Google Analytics 4 to understand how visitors use our website. This includes pages visited, time spent on pages, browser type, device type, and approximate geographic location (city level). This data is aggregated and does not personally identify you. You can opt out of Google Analytics by using the Google Analytics Opt-out Browser Add-on.
1.2 Affiliate marketplace cookies
When you click on a card link to eBay or TCGPlayer from our site, the affiliate network (eBay Partner Network or Impact Radius) may set a tracking cookie on the destination marketplace to attribute any purchase you make to us. This cookie typically lasts 7 days. We do not control these cookies and they are governed by the respective marketplaces' privacy policies.
1.3 No account, no personal data
We do not require account creation. We do not store user personal data, email addresses, or payment information. Visitors browse anonymously.
2. How we use information
We use the information we collect to:
- Provide and improve our price-tracking service
- Analyze website usage to improve user experience
- Track affiliate clicks for revenue attribution
- Respond to inquiries via email
3. Data sharing
We do not sell, trade, or rent your information to third parties. We share limited, anonymized data with:
- Google Analytics — anonymized website analytics
- eBay Partner Network — affiliate click tracking (only when you click an eBay link)
- TCGPlayer Impact (Impact Radius) — affiliate click tracking (only when you click a TCGPlayer link)

4. Cookies
We use cookies for basic functionality and analytics. Third-party services (Google Analytics, eBay, TCGPlayer affiliate networks) may also set cookies. You can manage cookie preferences through your browser settings.
5. Data security
All data transmission is encrypted using SSL/TLS. Our infrastructure is hosted on Vercel and Supabase with industry-standard security practices. We do not store sensitive personal data.
6. Your rights (GDPR)
If you are located in the European Economic Area (EEA), you have the right to:
- Request what data we hold about you (note: we don't store personal data)
- Request deletion of data
- Object to or restrict processing of your data
- Withdraw consent at any time
Since we don't collect personal data tied to user accounts, most GDPR rights apply only to the limited analytics data Google Analytics holds about your visits. To exercise rights related to Google Analytics data, please contact Google directly.

Our Service is not directed to children under 13. We do not knowingly collect personal information from children under 13.
