The purpose of these Terms is to set out the basic matters concerning the use of the Service provided by the Company, including the rights, obligations and responsibilities of the Company and users, and the conditions and procedures for use.
Article 2 (Definitions)

Article 3 (Posting and Amendment of These Terms)
- The Company posts these Terms within the Service or on this page so that users can review them at any time.
- The Company may amend these Terms to the extent that doing so does not violate applicable law.
- Where these Terms are amended, the Company gives notice from 7 days before the effective date, stating the effective date and the reason for the amendment. Where the change is unfavorable to users, notice is given from 30 days before the effective date.
- A user who does not agree to the amended Terms may stop using the Service and delete the app. A user who continues to use the Service after the announced effective date is deemed to have agreed to the amended Terms.
Article 4 (Formation of the Use Agreement and Eligibility)
- The use agreement is formed when a user installs and runs the app, agrees to these Terms and uses the Service. The Service has no sign-up or login procedure.
- The Service is not primarily intended for children under 14.
- A user under 19 must obtain the consent of a legal representative in order to purchase paid content, and a payment made without such consent may be cancelled by the user or the legal representative.
Article 5 (Provision of the Service)
- As a rule, the Company provides the Service 24 hours a day, every day of the year.
- The Company may suspend all or part of the Service where there is an operational or technical need, such as system inspection, maintenance or replacement, equipment failure, or a service update, and in that case gives notice in advance. Where there are unavoidable reasons, notice may be given afterwards.
- Communication and data charges needed to use the Service are borne by the user.
Article 6 (Storage and Management of Game Data)
- The Service does not create a separate account, and game progress, settings, purchase records and the like are stored inside the user’s device (local storage).
- Accordingly, game data may be deleted or may not be recoverable if the app is deleted, the device is reset or changed, or storage is damaged.
- Because the Company does not separately keep the data stored on a user’s device, it bears no obligation to recover data lost for reasons attributable to the user. This does not apply where the data was lost through the Company’s intent or negligence.
Article 7 (Purchase and Payment of Paid Content)
- Paid content is purchased and paid for through the payment methods provided by each Platform, and matters concerning payment and billing follow that Platform’s policies.
- The price, composition and usage period of paid content are shown on the purchase screen within the Service.
- Purchased paid content can be used only within the Service on that device and, under Article 6, may become unusable if the app is deleted or the device is changed.
- The Company may change the content or price of paid content where there is an operational or technical need, and gives notice in advance of any such change. Paid content already purchased remains subject to the conditions that applied before the change.
Article 8 (Withdrawal of Subscription and Refunds)
- Users may withdraw a subscription under applicable law, including the Act on Consumer Protection in Electronic Commerce.
- However, where withdrawal is restricted by the nature of the goods — as with paid content that is used or applied immediately upon purchase (goods consumed at once, the application of ad removal and the like) — withdrawal may be restricted as provided by applicable law. In that case the Company indicates this on the purchase screen.
- Payment cancellations and refunds are, as a rule, handled under the refund policy and procedures of the Platform on which the payment was made.
- Where paid content cannot be used for reasons attributable to the Company, the Company restores that content or refunds it under applicable law.
