Terms of Use
Last updated: Oct 27, 2026
This page is offered in several languages. If a translation differs from the English version, the English version applies.
These terms apply when you use DuelingAtlas, which is run by SanganThatDevours (contact: contact@duelingatlas.com).
The site
DuelingAtlas is a free Yu-Gi-Oh! card database, deck builder and collection manager, and an unofficial fan project, not affiliated with or endorsed by Konami. Yu-Gi-Oh! is a trademark of Konami; card names, card text and card images are ©2020 Studio Dice/SHUEISHA, TV TOKYO, KONAMI.
What you write and share
You are responsible for what you write: your nickname, deck and folder names, notes and deck descriptions, combo names, chat. Nothing illegal, hateful or harassing, nothing that infringes someone else's rights, and nobody's personal information. A nickname may not pass for the site, its staff or someone else.
What you write stays yours. By sharing or publishing it, you give us a free, worldwide, non-exclusive permission to store it, copy it and show it, for as long as it stays shared: a folder, a deck or a combo you share to anyone with its link, a shared folder also on your profile; a deck you make public also in the community's listings and search, on its own page, on your profile and on the pages of the cards it holds, under your nickname. You also let anyone copy a deck you share into their own decks, name and note included, and change it, play it, export it or share their copy; and anyone open a combo you publish and try out their own lines from it. A copy someone made stays theirs after you stop sharing yours. What you write in an online match's chat is kept in that match's record, which anyone with its link can see.
Reporting content
To report a deck, use the Report button on its page. For anything else, or if something here infringes rights you hold, write to contact@duelingatlas.com with its link and why it should come down. We review every report. Where something breaks these terms, we may hide the deck, remove the nickname or delete the account it comes from; we tell its owner why and, if you left a contact, tell you what we did.
Fair use
Don't disrupt the site or get around its limits: abusive traffic is slowed down or blocked.
Card data, prices and rulings
Card data is extracted automatically from Yugipedia, so it can contain parsing mistakes; we fix them as we find them, and corrections are welcome through the Feedback button. Prices come from Cardmarket, TCGplayer and yuyu-tei once a day, can be out of date, and are not an offer. The deck builder's legality checks and the duel table's rules engine are aids, not official rulings.
Your data in your browser
Without an account, your decks and collection exist only in your browser and are lost if its site data is cleared; signing in keeps a copy on our servers. How we handle your data is in the Privacy Policy.
As it is
The site is free and provided as it is: features may change or end, it may be unavailable at times, and its data may be wrong or out of date. Nothing here limits your rights as a consumer.
Ending
You can stop at any time, and delete your account from the account menu. We may delete an account that breaks these terms, and say why.
Changes
These terms may change when the site or the law does. A new version is posted here with its date; before a significant change applies, account holders are told by email and can delete their account if they disagree.
