Terms of Service

1. Who can use JK Index

You must be at least 13 years old to create an account, and old enough where you live to agree to these Terms yourself. If you are not, a parent or guardian must agree to them for you. Buying or selling on the marketplace, and any future paid Packs service, are for adults aged 18 or over.

2. Your account

Give accurate information when you sign up and keep your sign-in details private. You are responsible for what is done from your account. Do not create extra accounts to collect rewards, practice currency, or promotions more than once. If you think someone else has used your account, tell us at support@jkindex.io.

3. Beta features

Pricing, portfolio, marketplace, and Before the Slab features may contain incomplete data, temporary copy, or changing workflows. JK Index may update, pause, or remove beta features as coverage improves.

4. Prices and market data

Prices, sales, indexes, and charts on JK Index come from third-party sources and our own calculations. They can be late, incomplete, or wrong. They are information, not financial, investment, or appraisal advice, and not an offer to buy or sell a card at that price. Card prices go down as well as up. Make your own decision before you buy, sell, or grade a card.

5. Practice currency

Before the Slab $JKB is simulated practice currency only; it has no cash value and cannot be withdrawn or redeemed. Scores, streaks, badges, and leaderboard places are part of the practice experience. We may correct a balance or result that came from an error or from breaking these Terms.

6. Marketplace

Marketplace actions must be completed honestly and only by authorized account holders. Sellers are responsible for their listings, including accurate photos, condition, and price, and for completing the sales they accept. The details shown on a listing and at checkout apply to that transaction. JK Index may remove a listing or pause marketplace features to protect members or fix a problem.

7. What you post

You keep ownership of the photos, listings, decks, comments, and other content you add. You give JK Index permission to host, display, and share that content in order to operate the service, including on public pages and link previews, for as long as it stays on JK Index.

Only post content you have the right to share, and keep faces and personal information out of card photos. Some activity is public by default, including public collector profiles and Before the Slab practice activity and discussion. The Privacy Policy explains how your information is used.

8. Acceptable use

Do not use JK Index to:

• break the law or infringe someone else’s rights;
• harass, impersonate, or mislead other members;
• attack, overload, probe, or interfere with JK Index systems;
• scrape or bulk-collect data, or run bots or other automation, except through the API and connectors we publish and within their limits;
• exploit a bug or error, or manipulate prices, scores, leaderboards, practice markets, or promotions.

If you find a bug or a security problem, please report it to support@jkindex.io instead of using it.

9. Packs preview and affiliation

JK Index is an independent platform, not affiliated with, endorsed by, or sponsored by The Pokémon Company, Nintendo, Creatures, GAME FREAK, Riot Games, Bandai, Shueisha, or Toei Animation. Pokémon, Riftbound, One Piece, related names, trademarks, and card artwork belong to their respective owners. Showing a card or set does not imply an official partnership. Pack wrapper designs are original JK Index artwork, not official products.

Packs is currently a preview. You can browse it and try a free demo opening. A demo shows sample cards drawn with the chances shown for that pack. It costs nothing, and the cards in it are not saved, owned, or won. A demo result is not a promise about any future pack. Nothing can be bought, won, claimed, or shipped through Packs, and Crowns are not on sale. The contents, prices, and chances shown are proposals. They may change before launch, and Packs may not launch at all. Showing a card does not mean JK Index holds that card or that it will be offered.

The chances shown describe how often a card would be expected to appear across many packs. They are not a promise about any one pack, and no card is guaranteed. Card prices shown are reference estimates that can fall as well as rise. Packs are for collecting, not an investment.

If you ask us to email you when Packs opens, we will send one message about the launch. It does not reserve a pack, a price, or a place in line, and it is not a commitment to buy. You can turn it off in Email preferences.

Before any paid Packs feature opens, we will publish its terms and show them to you before you pay. They will cover the price, each pack’s contents and chances, which cards can be shipped, how Crowns work, refunds, shipping and replacements, and where and to whom Packs is available. Any future paid Packs service is intended for adults who meet the applicable local age and eligibility requirements.

10. Email choices

Policy-qualified accounts may receive occasional Article announcements or important product updates unless the account holder opts out. Regions requiring affirmative opt-in remain disabled until the account holder enables them. Every marketing message provides Article-specific and all-marketing unsubscribe controls.

Messages about your account’s security or your own transactions are not marketing and are sent regardless of these choices.

11. Other sites and services

JK Index shows information from, and links to, other sites and services, such as card marketplaces, grading companies, and payment or shipping providers. We do not control them, and their own terms apply when you use them.

12. JK Index content and takedown requests

The JK Index name, logo, site design, software, written content, indexes, and compiled data belong to JK Index, Corp. or its licensors. You may use JK Index and share links to it. Do not copy, resell, or republish our content or data in bulk without written permission.

If you believe something on JK Index infringes your copyright or trademark, email support@jkindex.io with the page address and a description of your work. We will review it and remove material where appropriate.

13. Suspending and closing accounts

You can stop using JK Index at any time. To close your account, email support@jkindex.io. We may limit, suspend, or close an account that breaks these Terms, puts other members or the service at risk, or where the law requires it. Where we reasonably can, we will tell you why.

14. No warranties and limits on liability

JK Index is provided as is and as available. We do not promise that it will be uninterrupted or free of errors, or that the data shown is complete or accurate.

To the extent the law allows, JK Index, Corp. is not liable for indirect, incidental, or consequential losses, or for losses from decisions made using information on JK Index. Nothing in these Terms removes rights you have under consumer law that cannot be waived or limited.

15. Changes to these Terms

We may update these Terms as JK Index changes. The date at the top shows the latest version, and significant changes are also announced on the site. Using JK Index after a change means you accept the updated Terms.
