Effective Date: August 26, 2026 (Enacted June 1, 2026) | H International

Article 1 (Purpose)

These Terms govern the conditions and procedures for the use of the HFLUX service (the "Service") operated by H International (the "Company"), as well as the rights, obligations, and responsibilities of the Company and users.

Article 2 (Definitions)

1. "Service" means the AI-based video, image, and audio generation platform HFLUX provided by the Company.

5. "AI-Generated Content" means all outputs such as images, videos, and audio generated through external AI APIs within the Service. The Service operates on the basis of generative artificial intelligence (AI), and all AI-Generated Content is generated by generative AI. Content from certain models (all image-generation models and Google Veo video) contains machine-readable markings inserted by the model provider (C2PA metadata, SynthID watermark); these markings are invisible and do not affect the quality of the content.

Article 10 (Changes and Suspension of the Service)

1. The Company may change the content and pricing of the Service, and will give prior notice of such changes.

   • Suspension, change, or policy change of an external AI API provider's service
3. If the Service is discontinued, the Company will give 30 days' prior notice and refund unused paid Credits.

Article 11 (Disclaimer Regarding AI-Generated Content)

1. Quality and accuracy of content: Due to the nature of AI models, generated outputs may differ from the user's expectations, and the Company does not warrant their quality, accuracy, or completeness.
2. Copyright and intellectual property: AI-Generated Content may include elements of existing works, and any copyright infringement disputes and legal liability arising therefrom are borne solely by the user. The Company does not pre-screen or warrant whether AI-Generated Content infringes copyright.
3. Illegal/criminal use: Civil and criminal liability arising from a user's use of AI-Generated Content for deepfake sexual crimes, fraud, defamation, threats, manipulation of public opinion, or other unlawful acts rests with the user, and the Company bears no legal liability whatsoever.
4. Harm to third parties: Liability for damages caused to third parties by AI-Generated Content (infringement of portrait rights, defamation, copyright infringement, etc.) rests with the user who used such content.
5. External AI API outputs: The Service uses external AI APIs such as Google, OpenAI, and BytePlus. The Company is not responsible for damages arising from policy changes, service suspensions, or changes in outputs of external APIs.
6. Response to legal disputes: In the event of a legal dispute related to AI-Generated Content, the Company may provide user information to investigative agencies in accordance with the law, and where the Company suffers damage due to a user's illegal conduct, the Company may exercise a right of indemnity against the user.
7. Storage and loss of outputs; backup responsibility: For the convenience of users, the Company may temporarily store outputs (video and audio) free of charge for up to 7 days. However, this is merely an ancillary convenience not included in the consideration for the service fee, and the Company assumes no obligation to store outputs and does not guarantee their storage. Users may download outputs to their own storage devices immediately after generation, and the Company provides such means (a download function) at all times; accordingly, responsibility for storing and backing up outputs rests with the user. Outputs may be deleted, damaged, or become inaccessible before the storage period elapses for each of the following reasons, and the Company is not liable for any damage incurred by the user as a result.
   • Reaching storage capacity limits, or early cleanup pursuant to storage cost or operational policy
   • Failure, maintenance, data corruption or loss of servers or cloud storage
   • Policy changes, account restrictions, service suspension or discontinuation by the cloud provider
   • Deletion pursuant to compliance with laws, requests from investigative or administrative agencies, or reports of rights infringement
   • Deletion in response to violations of these Terms, misuse, or security incidents
   • Force majeure beyond the Company's control, such as natural disasters, power outages or communication failures

   AI-Generated Content is not reproduced identically even under identical conditions, so recovery is impossible after deletion or loss, and the Company assumes no obligation to regenerate outputs or to grant equivalent credits. This shall not apply, however, to damage caused by the Company's intent or gross negligence.

Article 12 (Copyright)

1. The intellectual property rights of the software, UI, logos, and content created by the Company within the Service belong to the Company.
2. The right to use AI outputs generated by the user through the Service belongs to the user. However, the following apply:
   • The terms of use and copyright policies of the external AI APIs (Google, OpenAI, BytePlus, etc.) take precedence.
   • Legal determinations regarding the copyrightability of AI-Generated Content and the attribution of copyright must be verified directly by the user under the user's own responsibility.
   • The Company does not warrant that copyright in AI-Generated Content is attributed to the user.
3. The user bears responsibility for any copyright infringement arising from using another person's work as a prompt or reference image to train or generate with AI.

Article 13 (Collection of Service Usage Records)

1. The Company may collect and retain users' service usage records (generation history, access information, etc.) for the purposes of improving service quality, preventing misuse, and complying with the law.
2. Collected records may be provided upon a lawful request by an investigative agency.

Article 14 (Suspension of Use and Termination of Agreement)

1. If a user violates the prohibited conduct under Article 5, the Company may immediately restrict use of the Service or terminate the agreement without prior notice.
2. Upon suspension of use or termination, unused Credits are subject to the refund policy of Article 9; however, in the case of termination due to violation of prohibited conduct, refunds may be restricted.
3. Users may withdraw at any time via an email request or the account deletion feature.

Article 15 (Limitation of Liability)

1. The Company does not bear liability for damages in the following cases:
   • Service interruption due to force majeure such as natural disasters, war, or hacking
   • Service use disruptions arising from reasons attributable to the user
   • Damages caused by AI outputs generated by the user through the Service
   • Damages arising from the use of free services or free Credits
   • Damages arising from policy changes or service suspensions of external AI APIs
   • Disputes between users, or between a user and a third party
2. Even where the Company's liability for damages is recognized, the limit thereof shall not exceed the amount actually paid by the user for the relevant month.

Article 16 (Dispute Resolution)

1. Disputes concerning these Terms are governed by the laws of the Republic of Korea.
2. In the event of a dispute, the Company and the user shall consult in good faith.
3. If no agreement is reached, the matter shall be filed with the court having jurisdiction over the Company's location (Suwon District Court, Seongnam Branch).
