The Organizer agrees that the Company may receive and manage Support Funds paid by Supporters. When the Company receives the Support Funds, the Supporter's payment obligation to the Organizer in respect of those Support Funds is discharged.

Support Funds will be applied to advertising placement fees and other costs necessary to carry out the Project and will be paid or settled by the method prescribed by the Company. Organizers and Supporters acknowledge in advance that no bank transfer or other remittance to the Organizer may occur.

Article 8 (Creation of Projects)

  1. When creating a Project, the Organizer must accurately enter and disclose the following information:
    • (1) Project title, Project description, and plan details;
    • (2) Target Amount and fundraising end date;
    • (3) Project type (All or Nothing or All In);
    • (4) whether a designer has been appointed and the status of permission from the relevant agency or rights holder; and
    • (5) Project image (optional).
  2. The Organizer may request the Company or a third party designated by the Company to produce designs or create images.
  3. Once a Project has been created, it may not be canceled for the Organizer's convenience.
  4. If the Company determines that a Project or proposed publication is inappropriate, violates laws, public order and morals, or these Terms, infringes or may infringe the rights of a third party, the Company may suspend publication, request revisions, delete the Project, or take any other necessary action.
  5. When a Project is established—upon reaching the Target Amount for an All or Nothing Project or upon the end of the fundraising period for an All In Project—the Organizer must respond in good faith to emails and other communications from the Company, must not neglect communications required to advance the Project, and is obligated to carry out the Project.
  6. If the Organizer breaches the preceding obligation and remains unreachable for at least one week despite reasonable attempts by the Company to make contact, the Company may issue a final notice and, if there is still no response, assume authority to advance the Project and proceed at its discretion without the Organizer's consent. In such case, the Organizer may not object to the Company's decisions or handling of the Project.

Article 9 (Support, Payment, and Cancellation)

  3. Payments on the Service are processed using Stripe Payments ("Stripe"). Supporters must make payments in accordance with Stripe's terms and the procedures specified by the Company.

  8. As a general rule, Support cannot be canceled after payment is completed. This does not apply if an All or Nothing Project fails to reach its Target Amount or if the Organizer or the Company cancels the Project.

Article 9-2 (Advertising-Space Purchases, Payment, Cancellation, and Refunds)

  1. Members may directly purchase Advertising Space listed on the Service. Membership registration is required.
  2. An Advertising-Space Purchaser must pay the Advertising-Space Purchase Price by a payment method designated by the Company (credit card or bank transfer). Stripe Payments is used for both methods.
  3. The Advertising-Space Purchase Price consists of:
    • the pre-tax price of the Advertising Space;
    • consumption tax (10% of the pre-tax price, rounded up); and
    • a system usage fee (5% of the pre-tax price, rounded up).
  4. Payment processing at the time of application differs by payment method. For credit card payments, an authorization hold is placed at application and the charge is captured when the purchase is confirmed. For bank transfers, the purchaser makes the transfer after applying and payment is confirmed when the funds are received. In either case, after payment is confirmed, the Company checks availability, and the purchase becomes final only when the Advertising Space has been secured.
  5. If the Advertising Space cannot be secured, the Company will refund the full Advertising-Space Purchase Price, including the system usage fee.
  6. After a purchase is confirmed, it cannot be canceled for the Advertising-Space Purchaser's convenience. The Company will, however, issue a full refund in either of the following circumstances:
    • the Company cancels the advertisement due to unavoidable circumstances, such as failure to obtain permission from the relevant agency or rights holder; or
    • the Company otherwise determines that a refund is appropriate.
  7. The timing and method of a refund may vary depending on the payment method, payment provider, and related circumstances.
  8. After purchase confirmation, the Company will separately provide details regarding the publication schedule, design submission, and other requirements.

Article 10 (Advertising Fees)

No platform fee is charged when a Project is established.

Article 11 (Refunds)

  1. If an All or Nothing Project does not reach its Target Amount and is not established, the Support Funds will be refunded to Supporters. The system usage fee is non-refundable.
  2. If the Company cancels a Project because permission from the relevant agency or rights holder cannot be obtained or due to other unavoidable circumstances, the Company will refund the Support Funds and system usage fee in full by the method prescribed by the Company.
  3. The timing and method of a refund may vary depending on the payment method, payment provider, and related circumstances.

Article 12 (Public Information and User Content)

  1.
