Privacy Policy

Last updated: July 2026

Yugioh Decks is built to respect your privacy. We don’t require an account, and we don’t collect, sell, or share personal information. In short: the site works entirely in your browser.

What we store — and where

Your decks, your collection, and your preferences (like light/dark theme) are saved in your browser’s local storage, on your own device. This data never leaves your device and is never sent to us. Clearing your browser data removes it, and it won’t follow you to another device or browser.

Cookies & tracking

We don’t set advertising or cross-site tracking cookies, and we don’t run third-party advertising trackers. We use Google Search Console to understand how the site appears in search results — this is standard search-indexing data and does not identify individual visitors.

Third-party content

• Card data comes from the free YGOPRODeck API. Card images are self-hosted, with the YGOPRODeck image CDN as a fallback — loading a fallback image sends a normal web request to that CDN.
• Some pages link out to third-party sites (for example TCGplayer, Cardmarket, Yugipedia). Once you follow those links you’re subject to those sites’ own privacy policies.
• Web fonts are loaded from Google Fonts, which may receive your IP address as part of serving the font files.

Children’s privacy

The site does not knowingly collect any information from anyone, including children, because it does not collect personal information at all.

Changes to this policy

We may update this policy as the site evolves. Any changes will be reflected on this page with a new “last updated” date.
