・ "App": the iOS game application to which this EULA applies.
・ "User": an individual who downloads or uses the App.
・ "Agreement": this End User License Agreement (EULA).
This Agreement sets forth the rights and obligations of the User when downloading, installing, or using the App. By using the App, the User is deemed to have agreed to this Agreement.
The developer grants the User a limited, personal, non-exclusive, non-transferable license to use the App for personal entertainment purposes only. Commercial use, redistribution, reverse engineering, modification, and decompilation are prohibited.
The App does not require account registration or login. The App is designed to operate offline. User play data and settings may be stored locally on the device.
In-app paid features and subscriptions are handled through Apple-provided mechanisms and the libraries integrated in Xcode (e.g., StoreKit). The developer does not operate a custom payment server; subscription activation, renewal, and cancellation procedures and billing follow Apple’s interfaces and policies. The User agrees that Apple’s terms and privacy policy apply to purchase processing and payment.
Procedures for refunds and subscription cancellations are governed by Apple’s App Store policies and support procedures. The developer does not directly handle refunds for payments processed by Apple.
The App is provided \"as is.\" The developer disclaims all express and implied warranties, including but not limited to merchantability, fitness for a particular purpose, and non-infringement. To the fullest extent permitted by law, the developer shall not be liable for any damages arising from use of the App, including direct, indirect, special, consequential, or punitive damages.
The User acknowledges that content provided within the App (game data, images, audio, text, etc.) is owned by the developer or third parties with valid rights. The User will not reproduce, distribute, publicly transmit, or create derivative works from such content without authorization.
Copyrights, trademarks, and other intellectual property rights in the App and related documentation and content belong to the developer or rights holders. Except for the rights expressly granted under this Agreement, no other rights are transferred.
The App may store data locally on the device. The developer handles personal data in accordance with a separate privacy policy presented within the App. The App is designed not to use external servers; however, when using Apple-provided features (such as App Store purchase processing), Apple’s privacy policy applies.
The developer may amend this Agreement as necessary. For material changes, notice may be provided via app updates or in-app notifications. Continued use of the App after an update constitutes acceptance of the revised Agreement.
This Agreement is governed by the laws of Japan. All disputes arising from this Agreement shall be subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance.
・ If any provision of this Agreement is found to be invalid or unenforceable, the remaining provisions shall remain in full force and effect.
・ This Agreement constitutes the entire agreement between the User and the developer.
