Terms of Service

Article 1 (Purpose)
These terms govern the conditions and procedures for using the services provided by K-MUDANG (hereinafter "the Company"), including saju (Four Pillars of Destiny) analysis, compatibility readings, talismans (unlimited while credits remain) (hereinafter "the Service").

Article 2.1 (Face Reading Feature)
Face reading uses your device camera to provide entertainment and self-reflection content. Camera images and full facial coordinates are processed in your browser and are not transmitted to or stored on our server. If you choose to include face reading in Saju or compatibility, measurement categories, ratios and an interpretation summary are transmitted and stored as part of that AI reading request. If you choose an ink-and-wash portrait (1 credit), one front-facing photo is sent only to paint it and is not stored. The painting is an artistic reinterpretation that may refine your features; your face reading is based on the original capture, not the painting. This feature is not a scientifically validated prediction.

Article 2 (Nature of Service)
This Service provides entertainment and reference content based on traditional Eastern philosophy (Saju Myeongri). The results are not based on scientific or academic evidence and should not be used as the basis for important life decisions.

Calculation methods and differences between schools
The Four Pillars and solar-term transition times can be checked against calendar and astronomical data, the birth information entered and the time-correction settings applied. Judgments such as helpful elements, chart structure and Day Master strength can differ between schools, texts and studies because their methods and priorities differ. K-MUDANG applies its own rules informed by classical Ziping principles. It distinguishes balance from seasonal needs. For reviewed chart conditions, the function needed first becomes the Vital Element; support and caution describe what helps or burdens that function. Charts without an adopted priority retain a provisional application of the existing balance method. Seasonal selection and structural assessment cover implemented conditions, rather than every classical prescription or the complete theory of a particular school.
Differences in element judgments, chart structure or interpretation from other schools, texts, studies, practitioners or services alone do not constitute a calculation error or service defect and are not grounds for a refund of services already used.
If the Four Pillars or solar-term transition times differ from our stated calculation method, we review the input and settings to check for an actual error. This does not limit statutory cancellation or refund rights for confirmed calculation or system errors, or services that differ from their advertised or agreed description.

Article 3 (Eligibility)
The Service is available to anyone aged 14 or older. The reading feature requires a Google account login.

Article 3-2 (Account Creation and Privacy)
Your first sign-in creates a member account without a separate registration application. We process and store your sign-in account’s email, display name and profile image, your entered Saju details and optional MBTI, and reading and usage records to provide the Service. We do not collect your sign-in account’s password, email contents or contact list. Face-reading camera images are processed only in your browser, except one front-facing photo used to paint an ink-and-wash portrait if you choose one. See the Privacy Policy for the information processed, purposes and retention periods.

Article 4 (Reading Services & Payments)
1. Basic features (saju chart generation, basic compatibility analysis) are free and available with unlimited use after a simple sign-in.
2. Paid services are provided as credit packages. Credits are one shared pool — a single purchase works for Saju and Compatibility readings, follow-up questions and ink-and-wash face-reading portraits (one credit per portrait, used only when the painting is finished):
- Credits Package Trial ($7.50): 3 credits + unlimited talismans & compatibility talisman cards
- Credits Package Starter ($22): 10 credits + unlimited talismans & compatibility talisman cards
- Credits Package Standard ($41): 20 credits + unlimited talismans & compatibility talisman cards
- MVP tier: granted automatically once payments over the past year total about $164, and kept for one year from that moment. While MVP, all locked content stays open and talisman generation is unlimited even with zero credits; 10 credits are gifted on promotion, on each renewal, and every December 27. If yearly payments total less than $164, the account returns to the regular tier.
3. Services are delivered immediately upon payment. As digital content, cancellation is restricted once the service has begun, in accordance with the E-Commerce Act.
4. Full refund is available within 7 days of purchase if the service has not been used. 'Unused' means 0 readings; even without a reading, viewing the premium analysis cards unlocked by payment generating a talisman / compatibility talisman card, or receiving an ink-and-wash portrait counts as use of digital content and may restrict refunds. In addition, if a reading is interrupted or not produced normally because of inputs that run against the purpose of the service — such as requests to curse a third party, abusive language, or wishing misfortune on others — this does not constitute a service defect and is not grounds for a refund.
5. PayPal payments are charged in US dollars (USD). Card payments through Toss Payments are charged in Korean won (KRW). The checkout shows each payment amount for your selected plan. Refunds are issued to the original payment method.
6. Payment & refund inquiries: +82-10-5122-3255 / kmudang.official@gmail.com

Article 4-2 (Termination)
1. While signed in, select “Delete account” at the very bottom of the Korean, Japanese or English main page, below the business and customer support information. Review the notice and confirm with “Delete my account” to terminate your account.
2. Your account, Saju profile, readings and remaining credits are deleted and cannot be recovered.
3. Transaction records subject to statutory retention, including contract and payment records, are kept for five years and disconnected from your member account. Statistical and operational records are also disconnected from your member account.
4. If a payment qualifies for a refund, please apply before deleting your account so that we can check your usage. Deleting your account does not itself extinguish cancellation or refund rights under applicable law.

Article 5 (Disclaimer)
1. The Company does not guarantee the accuracy or completeness of any Service results.
2. The Company is not liable for any direct or indirect damages arising from use of the Service.

Article 6 (Intellectual Property)
All content, designs, and code of the Service belong to the Company. Unauthorized reproduction or distribution is prohibited.

Article 7 (Changes to Terms)
The Company may update these terms within the bounds of applicable law. Changes will be announced within the Service.
