YUNO AI Service Terms of Use

These Terms of Use govern the rights, obligations, and responsibilities of XtenB Co., Ltd. (hereinafter "Company") and its members in connection with the use of the YUNO AI service (hereinafter "Service"), as well as the conditions and procedures for using the Service. By agreeing to these Terms, the member is deemed to have fully understood and accepted all provisions below.

Terms used in these Terms of Use are defined as follows.

1. "Service" means AI-based mentoring that may use date, time, and relationship context (classical "four pillars" / Myeong-sik heuristics may be applied internally), daily rhythm and life-flow mentoring, AI chat, and all related supplementary services provided by the Company.
2. "Member" means an individual who has agreed to these Terms and registered for the Service in accordance with the Company's prescribed procedures.
3. "Subscription" means a paid payment model in which a Member makes periodic payments of a fixed amount to receive access rights to the Service for a specified period.
4. "Credits" means virtual currency used to access content within the Service, which may be purchased or provided free of charge in accordance with Company policy.
5. "Content" means all digital information and materials provided through the Service, including text, AI-generated analysis results, reports, and images.
6. "AI-Generated Content" means output automatically generated by generative artificial intelligence technology (e.g., Large Language Models). It is expressly noted that such content has not been directly authored or verified by the Company or any human expert.

This Article defines the legal nature of the Service and the scope of the Company's disclaimer. Please read carefully before agreeing.

1. [Entertainment & Reference Purpose] All time·temperament·relationship flow analysis and AI mentoring results provided by this Service are entertainment and reference information automatically generated from East Asian traditional heuristics, statistical rules, and generative AI. Under no circumstances do the results constitute or replace academically verified facts, medical diagnosis, legal advice, financial recommendations, or psychological counseling.
2. [Inherent Limitations of AI Technology] The Service utilizes generative AI, which may produce inaccurate information (hallucinations), different outputs for identical inputs, or content that does not match a member's circumstances. The Company makes no warranty regarding accuracy, completeness, reliability, or timeliness and shall not be liable for damages arising therefrom.
3. [Diversity of Interpretation] The same inputs may be phrased differently depending on the model or school of thought. Differences from a member's views or other services shall not be treated as a defect and shall not constitute grounds for refund or damages.
4. [Member's Responsibility] Members acknowledge that relying solely on AI-generated results for important life decisions may cause serious harm. Final responsibility for such decisions lies solely with the member.
5. [Professional Consultation] Members with medical, mental health, legal, or financial concerns should consult a qualified professional. This Service does not replace professional consultation.

1. Membership registration is completed by agreeing to these Terms and providing the information requested by the Company.
2. Members must keep registration information up to date. Disadvantages from false information are borne solely by the member.
3. Members are responsible for managing their account credentials. The Company is not liable for damages from account theft or unauthorized use by third parties.
4. Only one account per person is permitted. Sharing or transferring accounts is prohibited.

Because access to digital content is granted immediately upon payment, refunds are in principle unavailable except in the exceptional cases below. Please confirm before paying.

1. [Nature of Digital Content] This Service constitutes digital content and real-time services in which AI consultation access is granted immediately upon payment, pursuant to Article 17, Paragraph 2, Subparagraph 5 of the Act on Consumer Protection in Electronic Commerce (Republic of Korea). The consumer's right of withdrawal is limited once use has commenced.
2. [This storefront's billing] Payments are processed by Stripe in USD. Pro is $29 per month and Premium is $89 per month, billed every 30 days. Annual plans are not offered on this storefront. The Korean-won store (PortOne), including its 24-hour new-member coupon and annual discount, does not apply here.
3. [No refund of the current 30-day pass] The fee for the current billing period is non-refundable once paid, whether or not the Service has been used. Cancellation stops charges from the next billing date; you may use the Service until the already-paid period ends. Path: [Subscription] > [Manage] > [Cancel]. Credits already held are not extinguished by cancellation.
4. [One-time credit purchase] Credits are added immediately after payment, are valid for one (1) year from purchase, and cannot be transferred. Refunds go to the original Stripe payment method. A full refund is available only within seven (7) days of payment and only if no credit from that purchase has been used. Once any credit has been used, no partial or residual refund is available. Welcome, referral, and event credits are not refundable.
5. [Exceptional refunds] The Company may review: (1) a complete service outage attributable to the Company lasting 72 or more consecutive hours; (2) a duplicate charge due to a payment-system error (duplicate amount only). Refunds, if any, are made to the original payment method.
6. [Price changes] The Company may change fees with 30 days' prior notice. Continued use after the notice constitutes agreement to the revised fees.

1. All intellectual property rights related to the Service (including copyrights, trademarks, patents, trade secrets), UI/UX, AI algorithms, prompt configurations, knowledge databases, and content are vested in the Company.
