Terms of Use

OPTCG AI is a free, non-profit project for playing, practicing and learning the One Piece Card Game: matches against the AI and against other people, a deck builder, replays and the Meta section. We do not charge for using it and we do not sell cards or any other products.

The simulator is an unofficial re-creation of the rules: it may contain errors and differ from official rulings. It does not replace the official game or its products and services.

“One Piece Card Game”, its cards, card text, images, logos and game mechanics are © Bandai Co., Ltd. “One Piece”, its characters and artwork are © Eiichiro Oda / Shueisha, Toei Animation. All trademarks and images shown on this site belong to their respective owners.

We do not hold any license for, or own any of, these rights. OPTCG AI is not affiliated with, sponsored or endorsed by Bandai Co., Ltd., Shueisha Inc., Toei Animation Co., Ltd., Eiichiro Oda or any of their affiliates. We use this material in good faith, on a non-profit basis and for identification, informational and community purposes; its presence here does not imply ownership of it or any relationship with its owners.

If you hold rights, or act on behalf of someone who does, and want us to change or remove any content, please write to us. We will respond promptly and in good faith.

[email protected]

You are responsible for the activity on your account and for keeping access to it secure. Each person may have only one account. Do not use nicknames that are offensive or that impersonate someone else.

Playing on OPTCG AI also helps improve it. This is how we handle your matches and your data:

• They train the AI

  Matches played on the site, against the AI or against other people, may be used to train the AI and keep improving it.

• Public, anonymous replays

  By default, your finished matches may appear in Recent games with their replay, without your nickname, email or IP address, and without the chat. If you register, you can turn this off in your preferences for the matches you play afterwards.

• Your decks in Meta

  The decks you play with may appear in the public Meta section, always anonymously: they are shown with their Leader and date, never with your account, nickname or email.

• Your reports

  If you report a problem, we store your comment, the email you give us, the match at the exact point of the report and the technical data of your session. We use them to investigate the problem and reply to you.

• Emails, never advertising

  We will only write to you when needed: with the codes to sign in to or verify your account and, if you report a problem, with our reply, sent to your account email or to the address you give in the report. We will never send you advertising.

• If you ask to delete your account

  We delete your account, your sessions, your saved decks and the link between your account and your matches. The matches are kept without that link, and those already used to train the AI cannot be removed from the models.

Preferences · Meta · Privacy Policy

In matches against other people, and especially in the Competitive queue and its leaderboard, you must not:

• arrange results or lose on purpose to help someone else;
• use several accounts to play against yourself or to gain points;
• let a program play for you;
• deliberately exploit errors in the simulator or the server instead of reporting them;
• harass or insult other players;
• interfere with the operation of the service.

We may review matches and replays. If we detect a breach, we may void the affected results, correct the leaderboard, exclude the players involved from a season or a prize, and suspend or delete accounts.

The scoring guide explains how the leaderboard and its seasons work. We may correct scores affected by technical errors or abuse. When a season has a prize, it is governed by its own terms, which take precedence over these terms for the matters they cover.

How scoring works

You are responsible for what you publish: your nickname, the decks you share and your chat messages. We may remove content that breaches these terms. The Privacy Policy explains what is shown publicly about your matches.

Privacy Policy

The site is provided “as is”, without warranties. It may contain errors, change or become unavailable, and a match may be lost because of a failure or maintenance. To the extent permitted by law, OPTCG AI is not liable for any damages arising from the use of, or inability to use, the site.

We may update these terms. The current version and its date will always be published on this page. Continuing to use the site after a change means you accept the new version.
