Privacy Policy

Last updated: July 18, 2026.

OP Box Index ("we", "us", "the site") publishes research on One Piece Card Game booster box and graded-card prices at opboxindex.com. This policy explains what information is collected when you visit, how cookies and third-party services are used, and the choices you have. By using the site you agree to the practices described here.

Information we collect

The site does not require accounts, logins, payments, or contact forms, and we do not ask you to submit names, addresses, or payment details. We do not knowingly collect personal information that identifies you directly.

Like most websites, some information is collected automatically by the third-party services below — for example your approximate location (country/region), device and browser type, referring page, and pages viewed. This is used in aggregate to understand traffic and improve content.

Cookies and similar technologies

Cookies are small files stored by your browser. The site itself uses minimal local storage for basic preferences (such as your language toggle and any pins you save), which stays on your device and is not transmitted to us. The analytics and advertising services described below may set their own cookies or similar identifiers under their respective policies. You can block or delete cookies in your browser settings; some site features may then work differently.

Google Analytics

We use Google Analytics 4 to measure aggregate traffic (visits, page views, general location, device type). Google Analytics may set cookies and process data as described in Google's Privacy Policy. You can opt out across all sites with the Google Analytics Opt-out Browser Add-on.

Advertising and Google AdSense

The site may display ads served by Google, including through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.

• Google's use of advertising cookies (including the DoubleClick DART cookie) enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google Ads Settings.
• You can also opt out of a third-party vendor's use of cookies for personalized ads at aboutads.info/choices and youronlinechoices.eu (EU).
• How Google uses information from sites that use its services is described at policies.google.com/technologies/partner-sites.

Affiliate and paid links

Some outbound links are affiliate links, including the Amazon Associates Program and the eBay Partner Network. Affiliate links may be marked as "Paid Link" or similar. If you click one and complete a qualifying purchase, we may earn a commission at no additional cost to you. As an Amazon Associate we earn from qualifying purchases. These programs may use cookies to attribute a purchase to a referral; that data is handled under each program's own privacy policy. Affiliate relationships do not change the price data we publish.

Third-party links

The site links to external pages (such as eBay listings, Amazon, and official sources). We are not responsible for the content or privacy practices of those sites; review their policies before providing any information.

Children's privacy

The site is not directed to children under 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect personal information from them. If you believe a child has provided such information, contact us and we will address it.

Your choices and rights

Depending on where you live (for example under the EU/UK GDPR or the California CCPA/CPRA), you may have rights to access, correct, or delete personal data, and to opt out of personalized advertising or the "sale" or "sharing" of data as those terms are defined by law. Because the site does not collect directly identifying information, most control is exercised through the browser settings and the third-party opt-out links above. To make a request or ask a question, contact us using the details below.

Data retention

We do not maintain a personal-data database of our own. Aggregate analytics and advertising data are retained by the respective third-party providers according to their policies and your account settings with them.

Changes to this policy

We may update this policy as the site or applicable law changes. Material changes will be reflected here with a revised "Last updated" date. Continued use of the site after an update constitutes acceptance of the revised policy.
