ChapterN Terms of Service

Article 1 (Purpose)

These Terms set out the conditions for using ChapterN, a story content service (the "Service") provided by Zenumaik Co., Ltd. (the "Company"), and the rights and obligations of the Company and its users.

Article 2 (Definitions)

  1. "Users" include Members and non-members. A "Member" is a user who has registered through Google or Apple sign-in, age verification, and acceptance of the Terms.
  2. "Content" means the works and Chapters available through the Service, including their text, images, voices, music, and video.
  3. "Ink" is an account-specific means of opening paid Chapters within the Service. It consists of paid Ink purchased for a fee and free Ink granted at no charge.
  4. "Opening" a Chapter means granting the account access to that Chapter by spending Ink or using another disclosed method.

Article 3 (Registration and Accounts)

  1. Public work descriptions and other public features are available without registration. Account features, including saving progress, favorites, ending records, and purchases, require registration.
  2. Members must sign in with the Google or Apple account used to register. A different account or sign-in method is treated as a separate ChapterN account; progress, Ink, and purchase records are not merged.
  3. Members must provide truthful information required for registration, age verification, payments, and inquiries, and must not use another person's identity or payment method without authorization. If information changes or a Member discovers that it is incorrect, the Member must update it through the Service or notify the Company.
  4. Members must keep their sign-in accounts and devices secure. Upon discovering account compromise or unauthorized use, Members must promptly notify the Company and cooperate with reasonable measures to prevent harm. Article 13 governs harm caused or increased by false information or a breach of account security obligations.
  5. Where there are reasonable grounds to suspect false information, identity misuse, or a lack of payment authorization, the Company may request supporting information under Article 15. Restrictions to prevent harm are governed by Article 12.

Article 4 (Service and Content)

  1. The Service provides works combining text, images, music, and other media. In some works, readers' choices affect the story and its ending.
  2. The Company may use artificial intelligence as a production tool and provides Content after review and editing. The Service does not generate new story content in real time while you read.
  3. The Company may change or suspend the Service or Content when necessary for maintenance, failures, rights issues, or operations. It will give advance notice of the reasons and schedule when use is materially affected. When advance notice is impracticable, such as an urgent failure or rights infringement, notice will follow the action.
  4. Compensation for losses arising from the suspension, interruption, or defects of paid Content is governed by applicable law, Korea's Content User Protection Guidelines, and Consumer Dispute Resolution Standards. Requests for redress can be submitted through the contact channels in Article 15.

Article 5 (Age Requirements)

Registration is available from age 15. The Service offered through Indonesian app storefronts is for users aged 18 or older. A higher age required by applicable law or an app marketplace takes precedence. See the Age Requirement notice for details.

Article 6 (Purchasing Ink and Using Content)

  1. Paid Ink is purchased through Apple App Store or Google Play in-app purchases. Each product's Ink quantity, price, and payment conditions are displayed before purchase. Ink is credited to the relevant ChapterN account after payment and verification are complete.
  2. The Ink needed to open a Chapter is displayed before use. Free Ink is spent first, followed by paid Ink. Auto-open applies only when the Member selects it; its scope and how to disable it are explained on the selection screen.
  3. Paid Ink has no expiration date. Any expiration date for free Ink is disclosed when it is granted.
  4. Ink and Content access rights cannot be transferred, rented, or sold to another person. Ink cannot be used for payments outside the Service or exchanged for cash except through refunds under these Terms and applicable law.
  5. Members may read opened Chapters for personal use through the relevant account for as long as the Service is provided. Articles 4 and 12 apply if Content is withdrawn or the Service ends. Ownership of Content or copyright is not transferred.
  6. Whether Content is offered for a fee or free of charge, and the amount of Ink needed to open a Chapter, may change. Such changes do not affect access rights already acquired. A later discount or change to free access alone does not entitle Members to a refund of the difference in Ink already spent.

Article 7 (Personal Information and User Submissions)

  1. The Company processes personal information needed to provide the Service and handle inquiries in accordance with its Privacy Policy. Rights in ratings, inquiries, and other submissions remain with their respective rights holders. The Company uses submissions only as necessary for the purpose for which they were submitted.
  2. Users must have lawful authority to provide text, images, files, and other materials for the purpose of their inquiry or report, and must not infringe others' intellectual property, privacy, or other rights. This does not restrict lawful quotation or the submission of evidence for infringement reports where permitted by law.
  3. Users must reasonably cooperate in establishing the facts if a rights dispute arises concerning their submissions. Liability for harm to the Company or third parties caused by a user's intentional or negligent breach of paragraph 2 is governed by Article 13 and applicable law.

Article 8 (Withdrawal and Refunds)

  1. Members may request withdrawal from a purchase of unused paid Ink within seven days of receiving the electronic document setting out the transaction terms. If Ink is supplied later, the period starts when supply begins.
  2. Opening a Chapter with Ink starts delivery of that digital Content. Withdrawal for a Chapter whose delivery has started and the Ink spent may be restricted if the Company has given advance notice of the withdrawal restriction and taken the measures required by law, such as providing previews. Rights concerning separable Content whose delivery has not yet started and unused paid Ink remain unaffected.
  3. If Content or Ink differs from its description, advertising, or contractual terms, withdrawal is available within three months of supply and within 30 days of the date the Member discovered or could have discovered the discrepancy.
  4. Apple processes payment cancellations and refunds for Apple App Store in-app purchases. Members must request them through Apple's refund service or Apple Support; the Company cannot directly cancel those payments. For Google Play purchases, Members may use "Refund request" in the app, contact admin@zenumaik.com, or use Google Play's refund process. Service inquiries, including Content access issues, errors in granting Ink, or refund issues unresolved through the app marketplace, may be submitted to the Company regardless of the payment channel.
  5. Unused paid Ink is refunded upon withdrawal from a purchase or rescission or termination of the service agreement, in accordance with applicable law. Refund amounts are calculated based on the amount actually paid and the proportion of paid Ink eligible for refund. Free Ink is not refundable in cash. No separate refund fee or penalty is charged for statutory withdrawal.
  6. Where the Company directly issues a refund following a valid withdrawal, it does so within three business days of withdrawal. For marketplace payments, it promptly takes necessary measures, such as requesting that payment be stopped or cancelled. Procedures for refunds processed by an app marketplace, and when those refunds are reflected, follow that marketplace's guidance. Compensation for delayed refunds is governed by applicable law.
  7. Minors must obtain their legal representative's consent before paying where required by law. A minor or their legal representative may cancel a payment made without that consent as provided by law. However, where a minor uses deception to cause the Company to believe that they are an adult or have their legal representative's consent, cancellation on the grounds of minority may be restricted under applicable law. Applicable law also governs purchases made using property that the legal representative has authorized the minor to dispose of within a specified scope.
  8. Overpayments, including duplicate payments, may be reported through the channels in paragraph 4 and will be refunded through the original payment method after verification. If that method cannot be used, the reason will be explained and another method agreed with the user. Ink and Content access corresponding to a completed refund may be recovered.
  9. The Company may request necessary information under Article 15 to verify consent or authority to cancel a minor's payment and identify the transaction subject to a refund. Even where cancellation on the grounds of minority is restricted, other withdrawal or refund rights are determined under their applicable conditions.

Article 9 (Corrections to Ink and Access Rights and Repayment of Improper Refunds)

  1. The Company may correct or recover the affected Ink and access rights in cases of improper acquisition, duplicate or erroneous grants, payment cancellation, refunds, or chargebacks. It will explain the reason and scope, allow objections, and leave unrelated legitimate purchases unaffected.
  2. If a user receives a duplicate refund without a legal basis or obtains a refund through false information or improper means, the Company may demand repayment in accordance with applicable law. It will identify the transaction, grounds, amount, and calculation and allow the user to object.
  3. In determining repayment or recovery, the Company will account for amounts already repaid and other adjustments, including recovery of Ink and access rights, to avoid recovering twice for the same loss. A legitimate app marketplace refund request or exercise of statutory rights is not itself treated as improper conduct.

Article 10 (Prohibited Conduct)

Users must not:

  1. Use another person's account without authorization, allow another person to use your account, or transfer, rent, or sell an account.
  2. Obtain Ink or access rights through hacking, payment manipulation, exploitation of errors, unauthorized payment methods, or other improper means.
  3. Use false information or forged or altered materials to deceive checks of age, identity, or payment authorization, or obtain refunds improperly, including deliberately concealing an earlier refund to receive a duplicate refund.
  4. Disrupt the Service or use automation to impose abnormal loads.
  5. Collect, copy, or distribute Content in breach of Article 11 or infringe third-party rights.
  6. Reverse-engineer software or bypass access restrictions or technical protection measures beyond what applicable law permits.
  7. Disrupt customer support through abusive language, threats, sexual harassment, or similar conduct.

Article 11 (Content and Intellectual Property)

  1. Intellectual property rights protected by law in the Service, including Content, software, trade names, and logos, belong to the Company or the relevant rights holders.
  2. Users must not reproduce, distribute, communicate to the public, sell, translate, adapt, or otherwise reuse Content without the rights holder's permission.
  3. Without the Company's permission, users must not collect Content in bulk using crawlers, bots, or similar means, or collect Content and use or provide it as data for training or fine-tuning AI models.
  4. Users must not remove or alter source or rights-holder notices, watermarks, or other rights notices without lawful authority, or impersonate the Company or a rights holder. Users must not publish or provide Content in a way that falsely implies Company approval or presents another person's Content as their own creation.
  5. The Company may demand that violations of this Article stop and that necessary corrective steps be taken, including removal of Content posted or distributed in breach of this Article. Separately from measures under Article 12, it may seek remedies under applicable law and contract, including orders to stop or prevent infringement and compensation for harm. The Company acts within rights it holds or may lawfully exercise.
  6. This Article does not restrict lawful quotation, copying for private use, or other uses permitted by applicable law. Link-sharing features provided by the Company may be used as instructed.

Article 12 (Account Deletion, Restrictions, and Service Closure)

  1. Members may delete their accounts under [My > Account settings > Delete account]. Account data and access rights are deleted and cannot be restored, except for records retained by law. Refunds of unused paid Ink are governed by Article 8.
  2. Depending on the nature, seriousness, repetition, and resulting harm of a breach of these Terms, the Company may issue a warning, temporarily restrict use, or terminate the agreement. It will explain the grounds, scope, duration or conditions for lifting the measure, and how to object. Where urgent action is needed to prevent account abuse, attacks, or other harm, the Company may act first and give notice promptly afterward.
  3. If the Service closes, the Company will ordinarily announce the schedule and refund procedure at least 30 days in advance. Unused paid Ink will be refunded, and Article 4 governs measures concerning paid Content in use. The Company will provide a contact channel needed to handle refunds after closure.
  4. Where objective and reasonable grounds indicate possible identity misuse, improper payments, rights infringement, or similar violations, and action is necessary to prevent further harm, the Company may temporarily restrict the relevant account features or transactions while establishing the facts, to the minimum extent and for the minimum period necessary. It will give notice under paragraph 2, adjust measures in light of its findings, and promptly lift them when the grounds no longer exist.
  5. Users may submit explanations and supporting materials or object through the channels in Article 15. The Company will review them and communicate the outcome and reasons. Restrictions and objection procedures do not limit statutory rights to refunds, dispute resolution, or legal proceedings, and do not authorize forfeiture of legitimately acquired paid Ink unrelated to the violation.
  6. Settlement, repayment, and compensation obligations arising before account deletion or termination, and intellectual property and dispute-resolution provisions that by their nature need to survive, continue after termination. Retention and deletion of personal information follow the Privacy Policy and applicable law.

Article 13 (Liability and Its Scope)

  1. The Company and users are liable under applicable law for harm caused to the other by their intentional acts or negligence. The scope of compensation is determined by the causal connection between the breach and the harm, each party's responsibility, and applicable law.
  2. Compensation covers ordinarily arising losses. Losses arising from special circumstances are compensable under applicable law where the party liable knew or could have known of those circumstances. Where the injured party's negligence caused or increased the harm, that negligence is considered in determining liability and compensation.
  3. The Company is not liable, to the extent it bears no responsibility, for harm caused by a user's false information, account sharing or inadequate account security, use of devices or software outside the support scope disclosed in advance, or failures of external services such as telecommunications or app marketplaces. The same applies to harm caused by natural disasters or other force majeure for which the Company bears no responsibility.
  4. If a user, intentionally or negligently, breaches these Terms or infringes rights through submitted materials, and this causes the Company to suffer harm in responding to a third-party claim, the Company may seek compensation for losses and reasonably necessary response costs within the scope recoverable under applicable law. Amounts attributable to the Company's own responsibility are excluded. A settlement or expense chosen by the Company does not by itself make the user liable for its full amount.
  5. This Article does not exclude liability for the intentional acts or gross negligence of the Company, persons assisting in its performance, or its employees, or liability that cannot be excluded or limited under mandatory law.

Article 14 (Governing Law and Disputes)

  1. These Terms are governed by the laws of the Republic of Korea, without restricting mandatory consumer rights in a user's country of residence.
  2. Users may seek resolution from the Company or use dispute-resolution procedures provided by the Content Dispute Resolution Committee, the Korea Consumer Agency, or other competent bodies. Jurisdiction is determined by applicable law, including Korean electronic commerce and civil procedure laws.
  3. If a translation differs in meaning from the Korean text, these Terms are interpreted on the basis of the Korean text.

Article 15 (Notices, Verification, and Inquiries)

  1. The Company communicates through appropriate channels, such as app or website notices, in-app notifications, or registered email addresses. Matters requiring individual notice are communicated to the relevant Member.
  2. Service inquiries, refund requests, and reports of rights infringement may be submitted in-app or to admin@zenumaik.com. The Company will review them and communicate the outcome.
  3. To establish facts concerning account protection, purchases, refunds, or infringement reports, the Company may request the minimum necessary transaction records and information verifying identity, age, legal-representative relationships, authority to act, payment authorization, or relevant rights. It will explain the purpose and required information, and users must cooperate with reasonable verification requests. Unnecessary personal information may be redacted or replaced with alternative evidence. The Company does not request unnecessary information such as resident registration numbers or payment card numbers. Information is handled under the Privacy Policy and applicable law.
  4. Infringement reports must identify the Content and the grounds for the claim and provide information establishing that the reporter is the rights holder or an authorized representative. The Company may request necessary supplementary information. Receiving a report or taking a temporary investigative measure does not itself constitute an admission of infringement or Company liability.
  5. Verification does not permit the Company to unilaterally extend statutory deadlines or treat statutory rights as extinguished merely because information has not been submitted. The reporting and verification procedures in this Article are not prerequisites for exercising statutory rights.

Article 16 (Changes to the Terms)

  1. The Company may amend these Terms within the limits of applicable law, announcing the effective date and reasons seven days in advance. Changes unfavorable to Members' rights or obligations are announced and individually notified 30 days in advance.
  2. The Company obtains separate consent where required. Members who disagree may terminate their agreements; Articles 8 and 12 govern unused paid Ink and paid Content in use.

Article 17 (App Marketplaces)

App marketplace listings and policies also apply to service availability, installation, and in-app purchases. Neither those policies nor these Terms restrict statutory consumer rights.

Article 18 (Business Information)

Effective Date

These Terms take effect on September 9, 2026.
