Terms of Service

Version 2026-09-09 · last updated September 9, 2026

These terms govern your use of haki.ink (the "Service"). By signing in or using the Service you agree to them. If you do not agree, do not use the Service.

1. What the Service is

haki.ink is a simulator and coaching tool for the One Piece Card Game. It lets you play practice games against an AI opponent, review replays, and read aggregate statistics. haki.ink is an unofficial fan project, not affiliated with or endorsed by Bandai, Shueisha, Toei Animation or Eiichiro Oda. The One Piece Card Game and its cards are the property of their respective owners; the name is used here only to describe what the Service is compatible with.

2. Eligibility and accounts

• You must be at least 13 years old to use the Service. If you are under 18, you need a parent or guardian's permission.
• You sign in with a Google account. You are responsible for activity under your account and for keeping your Google credentials safe.
• Access may be limited to an allow-list or a waitlist while the Service is in beta. We may grant, limit, or withdraw access at our discretion.

3. Acceptable use

Do not: scrape, crawl, or bulk-download the Service; resell or redistribute its output; probe, overload, or interfere with it; use it to infringe anyone's rights; or attempt to access other users' data. We may suspend accounts that break these rules.

4. Paid plans

These terms apply when a paid plan ("Pro") is offered:

• Automatic renewal. A Pro subscription renews automatically at the end of each billing period at the price shown when you subscribed, until you cancel. You give separate, express consent to this at checkout.
• Cancel anytime. Cancel online from your Account page ("Manage subscription"). Cancellation takes effect at the end of the current period; you keep Pro until then.
• Refunds and withdrawal. Consumers in the EU and UK may withdraw within 14 days of purchase for a full refund. Elsewhere, refunds are handled case by case. Refunds are processed by our Merchant of Record.
• Merchant of Record. Payments are processed by Paddle.com Market Ltd, which is the seller of record, collects applicable taxes, and handles refunds and chargebacks. Paddle's buyer terms apply to the purchase.
• Price changes. We will notify you by email at least 30 days before a price change takes effect for your subscription.
• Annual reminders. We send a reminder before each annual renewal with the price, the renewal date, and how to cancel.

5. Your content

Decklists, feedback, and game records you create stay yours. You grant us a licence to store and process them to run and improve the Service, including aggregate, de-identified statistics. You can export or delete your data from your Account page.

6. Availability and changes

The Service is provided as is and as available. We may change, pause, or discontinue it, in whole or in part, at any time. We may also update these terms; the version number and date above change when we do, and continued use after a change means you accept the new terms.

7. Disclaimer of warranties

To the fullest extent permitted by law, the Service is provided without warranties of any kind, express or implied, including fitness for a particular purpose and non-infringement. Game results, statistics, and coaching advice are informational and may be wrong.

8. Limitation of liability

To the fullest extent permitted by law, our total liability for any claim relating to the Service is limited to the amount you paid us in the 12 months before the claim, or US$20 if you paid nothing. We are not liable for indirect, incidental, or consequential damages. Nothing here limits liability that cannot be limited by law, including consumers' statutory rights.

9. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate access for a breach of these terms. Sections 5 through 10 survive termination.

10. Governing law

These terms are governed by the laws of the State of California, USA, without regard to conflict-of-law rules, except where the consumer-protection law of your country of residence gives you rights that cannot be waived.
