Article 3 (Nature of Service, Limitations, and Disclaimer) ★ IMPORTANT

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 - Errors and Hallucinations] The Service utilizes generative AI technology, which has the following inherent technical limitations: (1) AI may generate inaccurate or factually incorrect information (commonly referred to as 'hallucinations'). (2) Different outputs may be produced for identical inputs on separate occasions. (3) AI-generated content may not align with the member's personal circumstances, values, or expectations. The Company makes no express or implied warranty regarding the accuracy, completeness, reliability, or timeliness of AI-generated results and shall not be liable for any damages arising therefrom.
3. [Diversity and Subjectivity of Interpretation] The same inputs may be phrased differently depending on the model, rules, or school of thought. The mere fact that AI analysis results differ from a member's subjective views, other services' interpretations, or previously encountered information shall not be considered a defect or fault in the Service, and shall not constitute grounds for payment cancellation, refund, or claims for damages.
4. [Member's Responsibility for Reliance on Results] Members acknowledge that relying solely on AI-generated results when making important life decisions (employment, resignation, marriage, divorce, investment, property disposition, medical decisions, etc.) may cause serious harm. Members agree that final responsibility for all such decisions lies solely with the member.
5. [Recommendation for Professional Consultation] Members with medical, mental health, legal, or financial concerns should consult a qualified professional in the relevant field. This Service does not replace professional consultation.

Article 4 (Membership Registration and Account Management)

1. Membership registration is completed by agreeing to these Terms and providing the information requested by the Company in accordance with the procedures set out within the Service.
2. Members must keep the information provided at registration up to date. All disadvantages arising from the provision of false information shall be borne solely by the member.
3. Members are responsible for managing their account ID and password. The Company shall not be liable for any damages resulting from account theft or unauthorized use by third parties.
4. Only one account per person is permitted. Sharing or transferring accounts to others is prohibited.

Article 5 (Payment, No-Refund Policy, and Subscription Cancellation) ★ IMPORTANT

Due to the nature of this Service, whereby access rights to digital content are granted immediately upon payment, refunds are in principle not available except in the exceptional cases specified below. Please confirm before making a payment.

1. [Nature of Digital Content] This Service constitutes digital content and real-time services in which AI consultation access rights and report viewing rights are granted immediately upon payment, pursuant to Article 17, Paragraph 2, Subparagraph 5 of the Act on Consumer Protection in Electronic Commerce (Republic of Korea). Due to this nature, the consumer's right to withdraw from a subscription agreement is limited.
2. [No-Refund Principle for Current Month's (Current Payment's) Charges] The usage fee for the current billing period, once payment is completed, shall not be refunded under any circumstances, regardless of whether the service has been used (including whether chat history exists, reports have been generated, or login history exists). This is because Service access rights are granted to the member at the moment of payment, constituting the commencement of digital content provision.
3. [Notice of Withdrawal Limitation] Once use of the Service has commenced (including initiating a chat with AI, generating or viewing a report, or accessing the Service), the consumer's right of withdrawal is restricted pursuant to Article 17, Paragraph 2 of the Act on Consumer Protection in Electronic Commerce. The Company provides separate notice of this on the payment and registration screens.
4. [Subscription Cancellation Procedure] Members may apply for subscription cancellation (cancellation of recurring payment) at any time via [My Page] > [Subscription Management] > [Cancel Subscription] within the Service. Upon completion of cancellation, no further charges will be made from the next scheduled billing date, and the member may continue to use all benefits until the end of the already paid billing period. Subscription cancellation does not constitute a refund of the current period's charges.
5. [Credit Refund Policy] Paid credits may be fully refunded only if requested within 7 days of purchase and not a single credit has been used (including receiving chat responses or viewing reports). No refund of remaining credits will be made if even one credit has been used. Credits provided free of charge (via events, promotions, etc.) are not eligible for refund.
6. [Exceptional Refund Processing] The Company may review refund eligibility only in the following cases: (1) A complete service outage attributable to the Company's fault continues for 72 or more consecutive hours; (2) A duplicate charge occurs due to a payment system error (limited to the duplicate amount). Even in such cases, refunds may be provided in the form of credits or service period extensions rather than cash.
7. [Changes to Payment Method and Pricing] The Company may change subscription fees and payment terms with prior notice (30 days in advance). Continued use of the Service after the notice of change constitutes agreement to the revised fees.
