Yu-Gi-Oh GENESYS Deck Builder Privacy Policy

1. Overview

This policy explains what information is stored or processed when you use Yu-Gi-Oh GENESYS Deck Builder. No account is required to build or save a deck.

2. Deck Data Stored on Your Device

Deck names, card selections, quantities, point caps, and the active deck identifier are stored in your browser's local storage. This allows multiple decks to remain available when you return using the same browser.

Local deck data is not uploaded to our servers. Clearing site data, using a different browser, or changing devices can remove or hide those decks, so export important lists as a backup.

3. Imports, Exports, and Share Links

• Imported files and pasted decklists are processed in your browser.
• Exported files are created locally and downloaded at your request.
• Share links contain an encoded copy of the deck name, cards, quantities, and point cap in the URL. Anyone who receives a link can read and copy that deck.

4. Analytics and Advertising

We use Google Analytics and Microsoft Clarity to understand site usage and improve the service. We also use Google AdSense to display advertising. These providers may process device information, browser information, IP address, page interactions, cookies, or similar identifiers under their own privacy policies.

You can use browser privacy controls, cookie controls, content blockers, or the privacy choices offered by those providers. Blocking these services does not prevent the local deck builder from storing decks in your browser.

5. External Content and Links

Card images and official references may be loaded from Yu-Gi-Oh! or other external websites. Visiting or loading third-party resources is subject to the privacy practices of those services.

6. Data Retention and Control

You control locally stored deck data. You can delete individual decks in the builder or clear this site's storage in your browser. Analytics and advertising providers apply their own retention periods to data they process.

7. Children's Privacy

The service is not directed to children under 13, and we do not knowingly request personal information from children under 13.

8. Policy Changes

We may update this policy when the site or its third-party services change. The current revision date will appear at the top of this page.
