10. Transaction history relating to coins shall be retained for the period determined by the Company.

1. The Service provides a feature that automatically generates HTML-format digital shikishi and other content (hereinafter referred to as "AI Output") using generative AI technology (hereinafter referred to as "the AI") based on text entered by the User, as well as materials such as images, videos, and audio (hereinafter collectively referred to as "Input Data").
2. As the AI, the Company uses generative AI models provided by the following companies (hereinafter collectively referred to as "AI Providers"). Processing is performed by the provider of the model selected by the User on the Service. The Company may add or change the models and AI Providers it uses, upon display on the Service.
   • Google LLC (located in the United States / model provided: Gemini)
   • Anthropic PBC (located in the United States / model provided: Claude)
   • OpenAI, L.L.C. (located in the United States / model provided: GPT)
3. When using the AI generation feature, Users agree that the following information will be sent to the AI Provider of the model selected by the User:
   • Text entered by the User (including selections and free-text answers to questions, message text, and revision instructions)
   • Meta information such as the dimensions and file size of image, video, and audio materials (the binary data of the materials themselves is not sent to the AI Providers for AI generation processing, and is stored in storage managed by the Company)
   • The AI Output most recently generated by the AI (only when using the revision feature)
4. In the manner in which the Company uses the AI (the enterprise APIs provided by each company), the information referred to in the preceding paragraph is not used by the AI Providers to train generative AI models. However, the AI Providers may retain such information for a certain period for purposes such as detecting fraudulent use and ensuring safety. Details of the handling of the information referred to in the preceding paragraph are governed by the privacy policies and similar documents established by each AI Provider.
5. Users warrant the following with respect to the Input Data:
   • That the User holds the rights necessary to provide the Input Data to the Service and the AI (including copyright, right of publicity, and consent to the use of personal information)
   • That, when inputting images, videos, or audio depicting a third party, the User has obtained the necessary consent from such third party for use by the Service and AI processing
6. AI Output is an estimated result that relies on training data and generation algorithms, and the Company does not warrant its accuracy, legality, usefulness, fitness for a particular purpose, or that it does not infringe the rights of any third party.
7. Users shall determine, at their own responsibility, whether to use AI Output as-is or after modification, and the Company bears no liability for any damage arising from the use of AI Output.
8. In using the AI generation feature, Users shall not engage in any of the following acts:
   • Providing Input Data for the purpose of infringing the rights of another person
   • Attempting to generate content that is discriminatory, violent, obscene, or otherwise contrary to public order and morals
   • Use that violates the terms of service or usage policies established by the AI Providers

The Company grants a prescribed free usage allowance for each calendar month, and use within that allowance requires no consideration. The free usage allowance resets each calendar month, and any unused portion cannot be carried over to a subsequent month. Use exceeding the free usage allowance, and use of any AI model that the Company displays on the Service as excluded from the free usage allowance, shall be made by consuming coins as set forth in Article 4-2. The number of coins consumed per use is displayed on the Service according to the AI model selected by the User.
