Niunnaeun Terms of Service

Effective date: November 4, 2026 · Last updated (posted): October 26, 2026

Notice of change · Posted October 5, 2026 · Takes effect November 4, 2026 We added a clause on advance notice when the woon required for content changes (at least 7 days before the effective date · at least 30 days for changes unfavorable to users) (Section 4, item 10), and a clause on the types of app notifications (notices necessary to use the service · news & event notifications only if you opt in) (Section 7-2). We also corrected the item numbering in Section 4 (no change in content). We added a clause that videos posted on the Niwoon Naewoon Plaza are deleted automatically 3 months after the posting date, and a note on how long chat-room photos and videos are kept (Section 5-2). Through October 6, 2026 the previous terms apply, and from October 7 to November 3, 2026 the terms effective October 7, 2026 apply. Amended October 8, 2026 (effective immediately) · A link gift clause has been added to Section 4, item 3 (receive within 6 months · expires without return of Woon after that · cancel before receipt for a return of Woon). This clause covers a new feature and does not change existing terms, so it applies from October 8, 2026. Posted October 26, 2026 · Takes effect November 25, 2026 · A sentence has been added to Section 4, item 2 stating that woon topped up by bank transfer is not refundable. As this change is unfavorable to users, it takes effect 30 days after posting.

1. Purpose

These Terms govern the conditions of use of the mobile application Niunnaeun (the "Service") provided by 싱크코 (the "Operator"), and the rights and obligations of users and the Operator.

2. Nature of the Service & Disclaimer (Important)

  1. All fortune content provided by the Service (Saju, Zi Wei Dou Shu, Tarot, daily fortune, compatibility, etc.) is entertainment and reference content based on traditional East Asian fortune-telling and astrology culture.
  2. Fortune results are not medical, health, legal, financial, investment, or career advice or diagnosis of any kind, and do not predict or guarantee future facts.
  3. Users must use fortune results for reference only. Important decisions regarding health, finances, career, etc. must be made based on the user's own judgment and consultation with relevant professionals.
  4. The Operator is not responsible for any decisions or actions taken by users based on fortune results, or for any consequences arising therefrom.

3. Accounts

  1. Some features (saving readings, purchasing paid passes) require sign-up (email or social login).
  2. Users are responsible for providing accurate information and keeping their accounts secure.
  3. Users may delete their account and related data at any time via Settings > Delete Account in the app.

4. Paid Services & Payment

  1. Some content is paid and is unlocked with the paid currency woon. Woon may be purchased through App Store / Google Play in-app purchases or by web payment (Toss Payments), and prices may differ depending on the payment route.
  2. The refund procedure differs by payment route.
    • Purchased in the app (App Store / Google Play): billing, charging and refunds follow each store's policy, and refunds must be requested directly from the store. The Operator does not hold store payment method information (card numbers, etc.).
    • Purchased on the web: handled by the Operator directly. Unspent woon may be refunded within 7 days of payment (Article 17 of Korea's Act on the Consumer Protection in Electronic Commerce, Etc.). Details follow the Cancellation and Refund Policy. However, woon topped up by bank transfer is not refundable (for deposits confirmed on or after November 25, 2026 · Cancellation and Refund Policy 2.1.1).
    • On either route, woon already spent is not refundable, as the content has already been delivered.
  3. Woon purchased with payment is valid for 1 year (12 months) from the payment date. Woon added before the effective date of this clause (21 September 2026) is valid for one year from that date. We notify you 30 days before the validity period ends. Woon received for free (ad rewards, events) is not covered by this clause.
    • The usage period and the refund-eligible period of paid Woon are limited to within 1 year from the payment date. This 1 year is the maximum period; actual refunds follow the conditions for web payments — within 7 days of the payment date, for unspent Woon (Article 17 of the Korean E-Commerce Act).
    • Web refunds are returned to the original payment method; the per-transaction top-up limit is KRW 100,000. Paid Woon cannot be transferred to other users.
    • Gifts can only be sent as content vouchers; Woon is never transferred to other users. A voucher is purchased with the sender's Woon and can be used only for its content within 90 days of receipt. Vouchers cannot be refunded, exchanged for Woon or cash, or re-gifted. A voucher not used within 90 days expires, and the Woon is not returned.
    • Link gifts: The sender can send a voucher as a link in the form niwoon.com/g/<code>. The recipient does not need to be a friend or a member and can receive it after signing up and logging in. Because anyone who has the link can receive the gift, keeping the link safe is the sender's responsibility. A voucher sent by link can be received only once, by the first account that logs in, and not by the sender. The gift can be received within 6 months of being sent; if no one receives it within 6 months, the gift expires and the Woon spent is not returned. Before it is received, the sender may cancel the gift, and the Woon spent is then returned to the sender. Once received, a gift cannot be cancelled, and the voucher can be used only for its content within 90 days of receipt, as stated above, with no refund, exchange or re-gifting.
  4. Once purchased and viewed, content is retained for one (1) year from the date of purchase for that chart/item, and re-viewing the same content within this period is not charged again. After the retention period (1 year) elapses, the stored reading is deleted, and re-purchase is required to access it again. The retention period applies per content (reading). However, one-time consumable items (e.g., follow-up questions, dream interpretation) are not subject to retention and are delivered upon generation.
  5. Passes belong to the purchasing account. Passes bought while logged out are transferred to the user's account upon login, with the user's consent.
  6. Stored readings are linked to the relevant chart (Saju information). If a user deletes a chart in the app, the paid readings linked to that chart are deleted along with it. As this is a deletion by the user's own choice, re-registering the same or a new chart to access it again requires re-purchase, which is non-refundable.
  7. Where a payment is cancelled or refunded on the payment route (App Store, Google Play or the payment gateway), the Operator reclaims the woon credited by that payment together with any bonus woon applied to it. If the woon to be reclaimed has already been spent, the balance may show as negative, and use of paid content may be restricted until the negative balance is cleared.
  8. Where a payment completed but no woon was credited, the Operator will check the payment records of the payment gateway or the store and then either credit the woon or cancel the payment. The Operator may ask for the payment date and order number in order to verify this.
  9. Woon granted without consideration through testing or by error may be reclaimed by the Operator.
  10. We set how many woon each piece of content requires. If we change it, we will announce the change and its effective date in the app at least 7 days in advance (at least 30 days for changes unfavorable to users). This does not affect the woon you already have or content you have already purchased.

5. User Obligations

Users must not:

  1. Reverse-engineer the Service, use abnormal automated access, or improperly bypass payment/pass gates;
  2. Register or misuse another person's account or personal information (e.g., birth data) without consent;
  3. Engage in any act that interferes with the normal operation of the Service.

5-2. Retention of Posts and Attachments

  1. Videos you post on the Niwoon Naewoon Plaza are deleted automatically 3 months after the posting date. Your posts and comments remain.
  2. Photos and videos exchanged in chat rooms are kept as set out in the Privacy Policy.

6. Intellectual Property

All intellectual property in the Service — content, design, reading-generation logic, and interpretation materials — belongs to the Operator. Users may use it for personal, non-commercial purposes only.

7. Changes / Suspension of Service

The Operator may change the Service or temporarily suspend it due to force majeure or technical reasons. In the event of payment errors, a payment gateway outage or maintenance, the Operator may suspend only the payment function (this does not affect the crediting of woon for payments already completed). Notice will be given where reasonably possible.

7-2. Notifications

  1. We may send notices necessary to use the service — such as payments, expiry of woon, security and changes to these Terms — by in-app notification, web notification or email.
  2. News & event notifications (advertising information) about events, polls, new features and offers are sent only to members who have opted in, as described in section 2-1 of the Privacy Policy. You can withdraw consent at any time in Settings > Notifications.

8. Limitation of Liability

  1. Except as required by applicable law, the Operator is not liable in connection with the use of free services.
  2. Per Section 2, the Operator does not warrant the accuracy, completeness, or reliability of fortune results.

9. Changes to These Terms

The Operator may amend these Terms within the bounds of applicable law, with notice of the effective date and changes in the app or on this page.

10. Governing Law

These Terms are interpreted under the laws of the Republic of Korea.
