1. General Educational Purpose

The AI Yamato platform, including all AI-powered writing assistants, oral practice modules, grammar checkers, vocabulary drills, audio generation, and visual diagrams (collectively, the "Service"), is designed exclusively as an educational learning aid. The Service is intended to support a global community of learners—including middle school students, high school students, and adult learners worldwide—in practicing and improving their Japanese language skills.

2. No Guarantee of Exam Results or Academic Scores

While we strive to provide high-quality tutoring logic, standard curricula alignment, and comprehensive practice tools, AI Yamato does not guarantee 100% specific academic results, language proficiency test scores (such as JLPT or school exams), or certification outcomes. Learner performance depends heavily on individual effort, consistency, external instruction, and various personal factors beyond our control.

3. AI-Generated Content and Accuracy

The Service utilizes advanced artificial intelligence models (such as LLMs) to generate feedback, translations, essay corrections, and conversational responses.

• Potential for Inaccuracies: AI models can occasionally produce errors, misinterpretations, or unnatural phrasing.
• User Responsibility: Users, students, and adult learners are solely responsible for verifying the accuracy, appropriateness, and academic integrity of any feedback, corrections, or content generated by the AI before submitting work to schools, teachers, or professional institutions.

4. Service Availability and Technical Interruption

We endeavor to maintain high availability of the Service through robust cloud infrastructure (Cloudflare and Supabase). However, we do not warrant that the Service will be uninterrupted, timely, secure, or error-free. We shall not be held liable for any temporary service disruptions, maintenance downtime, third-party API outages, or data loss beyond our reasonable control.

5. Credits, Campaigns, and Promotional Terms

Any promotional campaigns, daily login bonuses, or complimentary credit grants are subject to specific terms and validity periods (e.g., expiration dates specified during campaign periods). Unused promotional credits will automatically expire upon the conclusion of the stated validity term. We reserve the right to modify or terminate credit promotion rules at any time without prior notice.

6. External Links and Third-Party Services

The Service may contain links to external websites, payment gateways (e.g., Stripe), or resources not operated by us. We assume no responsibility or liability for the content, privacy policies, or practices of any third-party websites or services.
