Who can use the game and accounts

You can use the game if you are 13 or older (14 or older in Korea; 13–16 or older in the EEA, depending on the country). If you are younger, you need permission from a parent or guardian. You can buy paid products if you are old enough to make contracts where you live, or with a parent's or guardian's consent.

In Korea, if someone under 19 paid without the consent of a legal guardian, they or their guardian can cancel the contract. If the contract is cancelled, everything paid is refunded. To cancel, ask the store you paid through (Apple or Google).

The game

Prices and payment

Prices are shown on the store payment screen (in Korea, as the total including VAT). Payment is only through the App Store or Google Play.

You are responsible for the internet access and data charges for using the service.

Paws and items

Right of withdrawal and refunds

We only sell paid products in the apps (the iOS app through the App Store, the Android app through Google Play). Payments and refunds follow Apple's and Google's policies and processes, and refunds for a cancelled purchase are also made by the store you paid through. Your rights under the law stay the same.

How to ask The store refund request pages below are the withdrawal function (European Union) and the withdrawal button (Argentina). Please include the order number (in your receipt email), the purchase date and the product.

Right of withdrawal by country

CountryRight of withdrawal
KoreaWithin 7 days of buying. However, as the shop tells you before payment, you can't cancel for paid paws you've already spent, including paws that come with other products (Korean E-Commerce Act, Article 17(2)5 and 17(6)). Unspent paws, products bought once and kept, and items you received with them can be cancelled within this period. If a product differs from its description or doesn't work properly, you can cancel within 3 months of the day you bought (received) it, and within 30 days of the day you found out, or could have found out, about the problem.
European UnionWithin 14 days of buying, without giving a reason. If, when you paid, you agreed in the store to immediate supply and acknowledged that you lose the right of withdrawal, and the store sent you a confirmation, you can't withdraw once supply has started. Without that consent or confirmation, you can withdraw and don't have to pay for what you used.
United KingdomYou can cancel within 14 days of buying (right to cancel). If you agreed to immediate supply and acknowledged that you would lose the right to cancel when you paid, you can't cancel once supply has started (Consumer Contracts Regulations 2013, reg. 37).
JapanBecause these are digital products, we don't accept withdrawal or returns for your own reasons. Including when a product has a defect, Apple's and Google's policies and processes apply.
BrazilWithin 7 days of buying (direito de arrependimento). You get your money back through the store you paid with, by the same payment method.
ArgentinaWithin 10 days of buying (arrepentimiento)
ChileWithin 10 days of buying (retracto)
MexicoWithin 5 business days of buying (revocación)
ColombiaWithin 5 business days of buying (retracto)
Other countriesUnder the refund policy of the store you paid through and the law of your country

Information we send to the store When a refund request reaches Apple or Google, we may tell that store whether the item from the purchase was delivered and give our view on the refund, to help the store decide. By paying in the app, you agree to us sending it. The store decides whether to refund.

Nicknames and reports

There is no chat in the game. The only text players see from each other is the nickname, which the game generates automatically. In online matches, other players see your nickname and the look you chose, and we use nicknames only as far as needed to show them in the game.

Nickname rules You must not tamper with the app to use nicknames like the ones below. We can remove or change such nicknames without notice and restrict that user's online play.

Point of contact We receive reports, appeals and contact from authorities (including EU authorities) directly at a single point of contact: support@bang9.dev. We answer in Korean and English, and you can also write in the game's languages (Japanese, Spanish, Portuguese).

Reporting If you see a problem nickname, send us the nickname, when you saw it and the mode (Quick Match, Item Battle, Arena). We review reports without delay, remove nicknames that break the rules or restrict that user's online play, and tell you the outcome.

Blocking Online matches are short (about 90 seconds) and players are matched fresh each time. If you'd rather not meet other players, you can play Practice mode (against bots only).

Copyright notices If your work is used in the game without permission, send us the work, where the infringing material is, your contact details and a statement that you are the rights holder. We have no DMCA agent registered with the US Copyright Office; notices go to the same point of contact. We restrict users who repeatedly infringe copyright.

Prohibited conduct and restrictions

You must not:

If you do, we can block you from online matches, reverse ratings or rewards, or suspend your account, and if you seriously break these terms, we can end our agreement with you. If we have a way to reach you, we tell you the reason.

If your nickname was removed or your use was restricted and you think it was a mistake, send an appeal to the point of contact in Nicknames and reports. We review it again without delay and tell you the result and the reasons. If we got it wrong, we undo it.

Rights

The game's software, art, music and name belong to us or their original creators. We give you a personal, non-commercial right to use the game under these terms. You can't transfer this right. Items you buy are the same kind of license. Fonts and open-source software in the game follow their own licenses.

Stopping and deleting your account

You can stop using the game at any time. Delete your account in Settings → Account → Delete account; your account, cloud save and rating are deleted immediately. See Delete Your Account for details. If you want a copy of your cloud save before deleting, ask us.

Limitation of liability

Changes to these terms

If we change these terms, we post what changed and the effective date on this page at least 7 days before (30 days if the change is bad for you). If you don't agree, you can stop using the game and delete your account before the effective date.

Governing law and disputes

Store terms

Apple's Standard License Agreement (EULA) also applies to the iOS app. These terms govern the game service (online matches, accounts, items), and payments follow each store's terms.

Users in Korea

Under Article 28 of Korea's Content Industry Promotion Act, we tell you where these terms differ from Korea's content user protection guidelines.

Users in the European Union

Other country terms

United Kingdom Under the Consumer Rights Act 2015, digital content must be of satisfactory quality and as described. If it isn't, you can get a repair, replacement, price reduction or refund. For the right to cancel, see Right of withdrawal and refunds.

United States California users can contact the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by phone at (800) 952-5210. You can bring claims in court, including small claims court.

Japan These terms are standard form terms (teikei yakkan) under Art. 548-2 of the Civil Code. They become part of our contract when you start using the game or buy a paid product. Under the Consumer Contract Act, clauses that exempt us from liability for intent or gross negligence, or that one-sidedly harm consumers' interests, are void. Before changes take effect, we publish the changes and the effective date on this page (Civil Code Art. 548-4). Seller information: 特定商取引法に基づく表記.

Brazil These terms don't reduce your rights under the Consumer Defense Code (CDC). Clauses that limit your rights are in bold in Key points. You can take disputes to your state's consumer protection agency (Procon).

Mexico, Argentina, Chile and Colombia Your country's consumer protection law applies (Mexico's Federal Consumer Protection Law, Argentina's Consumer Protection Law 24.240, Chile's Consumer Protection Law 19.496, Colombia's Consumer Statute (Law 1480 of 2011)), and withdrawal goes through the store refund process. You can complain to us or to the Federal Consumer Protection Agency (PROFECO, Mexico), the consumer protection authority (Defensa del Consumidor, Argentina), the National Consumer Service (SERNAC, Chile) or the Superintendence of Industry and Commerce (SIC, Colombia).
