ZUKU Constitution

ZUKU Constitution

Foundational Service Rules

Proposed text 2.0.0 · Review date October 7 2026 · Publication and commencement require Operator confirmation.

Preamble

ZUKU seeks an order in which creation and enjoyment respect the rights of others. Creative freedom rests on legitimate authority and responsibility; operational authority is bounded by users' rights and fair procedure. In an environment shared by people and automated systems, technical capability does not substitute for permission. This Constitution establishes principles for the operator and users, to be applied consistently to new technologies and conduct according to their purpose and substance.

Chapter 1 Foundational Order

Article 1 Purpose and Legal Character

(1) This Constitution establishes the foundational rules for the use, creation, development, transactions and operation of ZUKU, operated by Tresillo. Tresillo is referred to as the Operator and this Constitution as these Rules.

(2) These Rules are the Service's foundational governance rules and contractual terms to the extent lawfully incorporated. They shall not be construed as legislation, a court order or a source of independent punitive, investigative or compulsory enforcement powers.

(3) The Operator shall apply these Rules to its own operational conduct and assign responsibility for compliance and enforcement to duly authorized personnel.

Article 2 Scope and Actors

(1) These Rules apply to officially offered ZUKU services and their associated creation, development, integration and distribution facilities. A change in delivery method, access medium, technology name or functionality does not alone remove their application.

(2) A User is any person using the Service, whether registered or not, including creators, developers and persons performing operational work. The same conduct standards apply to acts carried out by automated means.

(3) An Agent is a system that automatically collects, evaluates or generates information or executes tasks under human instructions or a defined objective, regardless of whether it is called a language model, crawler or another tool, or of its degree of autonomy. Contractual responsibility shall be assessed by reference to the authority and fault of the person delegating, operating or managing it and applicable law; legal personality of the system is not presumed.

Article 3 Effect and Relationship of Rules

(1) Mandatory law and statutory rights prevail over these Rules. Valid individual agreements and licenses for particular works or software shall be respected within their respective subject matter and scope.

(2) Contractual obligations arise when the necessary presentation, explanation, assent and other procedures make them effective for the person concerned. Publication or viewing of a document, unregistered access or an automated visit shall not alone be deemed assent to all obligations. Contract formation shall be distinguished from satisfaction of access conditions lawfully established by the Operator.

(3) Supplementary policies may implement these Rules but shall not unilaterally reduce their fundamental protections. Unpublished internal guidance shall not create new User obligations or grounds for sanctions.

Article 4 General Interpretation and Its Limits

(1) Permissibility shall be assessed by considering purpose, the basis and scope of authority, rights in the subject matter, method of execution and anticipated or actual effects. Substance takes precedence over labels or form.

(2) The conduct categories in these Rules express their governing purpose. Substantially equivalent infringements or circumventions of authority cannot be justified by renaming, dividing conduct or delegating it to a third party. Such interpretation is limited to what can reasonably be foreseen from the published Rules.

(3) Ambiguous language shall be interpreted fairly under good faith and applicable law; unclear contractual terms shall be interpreted in favor of the User. Interpretation shall not create new crimes, fixed damages obligations or unforeseeable serious sanctions.

(4) A person deciding a restriction or sanction shall identify the applicable provisions and established facts. Where standards for a new category of conduct are needed, they shall generally be published before application to future conduct.

Article 5 Fundamental Rights and Operational Principles

(1) Lawful creation, enjoyment, criticism, satire, complaints and exercise of rights shall be protected. Criticism of the Operator or use of a competing service shall not alone result in adverse treatment.

(2) The Operator shall act on the basis of facts, necessity, proportionality, consistency and reviewability. Disability, health, gender, origin or mere reputation shall not be treated as evidence of a violation.

(3) Users shall have an opportunity to receive explanations of their rights and material conditions and to seek legitimate data access, deletion, account closure, refunds and review. Their scope and procedures are governed by applicable law and valid agreements.

Article 6 Authenticity of Accounts and Authority

(1) Account and organizational permissions shall be used under authentic identities and within valid authorization. Credentials shall not be stolen, traded or shared without authority, and authorized persons shall not be impersonated.

(2) Authority is limited by purpose, subject matter, scope and duration. Public accessibility, possession of a credential, a job title or past permission does not establish unrestricted present authority.

(3) Access may be temporarily restricted where compromise or mistake is reasonably suspected, with opportunities for recovery and explanation. Strict liability shall not be imposed collectively on an account holder or persons sharing an access environment.

Chapter 2 Creation and Rights

Article 7 Lawful Use of Protected Works

(1) Protected works shall be used through the resource-delivery and integrated-execution channels and conditions permitted by the Operator and the relevant rights holder. Use of protected works identified as ZWF3 through ZUKU Runtime requires compliance with both authorized resourcing and embedding conditions.

(2) Without legitimate authority, protection measures shall not be removed, altered or bypassed, and protected resources shall not be extracted, converted or reconstructed as independent copies for publication, transmission or distribution. Equivalent conduct is governed by the same standards despite changes of format or name.

(3) Temporary processing necessary for authorized execution is legitimate within the permission granted. Individual licenses and statutory exceptions shall be respected, while whether a particular exception also permits circumvention of a separate protection measure shall be assessed under its own legal requirements.

(4) A license to a public execution tool or specification does not include permission to use protected works or non-public protection functions. Distribution of the public execution tool excludes ZWF3 protection functions not separately licensed, and the Operator shall ensure that actual distributions and notices accurately reflect that boundary.

Article 8 Legacy Works and Nonretroactivity

(1) The policy cutoff for simple extraction of Flash works formerly provided through Jujeonja.com is October 1, 2026 at 00:00 Korea Standard Time. This cutoff is not the effective date of these Rules.

(2) New contractual obligations and sanctions shall not apply retroactively to simple extraction completed before the cutoff. For conduct after the cutoff, new contractual restrictions apply only after the relevant conditions become validly applicable to that User.

(3) A notice communicating a new policy concerning past conduct shall request prospective compliance or cessation. It does not excuse independently established infringements under the law applicable at the time or waive third-party rights. Subsequent publication or distribution shall be assessed separately.

Article 9 Creator Rights and the Operator's License

(1) Rights in works remain with their holders. The Operator receives from an authorized publisher only the nonexclusive license necessary to host, store, display, transmit and execute the work and make it available within the visibility selected by the User.

(2) Technical adaptation and use by service providers shall be limited to what is necessary for that purpose. Independent commercialization, advertising outside the Service, general-purpose model training and sale of training data are not included without separate authority.

(3) Following deletion or reduced visibility, new public use shall cease, leaving only necessary technical cleanup and lawful retention. Previously valid public licenses and lawful third-party rights shall be respected separately.

Article 10 Publication and Verification of Rights

(1) Publishers shall hold the necessary rights and permissions for a work and its components and provide required attribution, usage conditions and modification notices. Another person's rights or identity shall not be falsely represented.

(2) Public viewing, attribution, noncommercial purpose, purchase or successful technical inspection does not alone grant authority for redistribution, adaptation, training or other distinct uses. The Operator shall not represent publication approval as verification of every right.

(3) Authorized use of works and uses supported by statutory exceptions shall be protected. Their applicability shall be assessed for each right asserted and each specific act.

Article 11 Public Technology and Distinct Rights

(1) Public software and specifications are governed by their actual licenses. These Rules do not revoke previously valid rights to modify, distribute or interoperate.

(2) Software rights, Service access, rights in works and permission to use protection functions are distinct. Possession of one does not establish the others.

(3) Names and marks shall not be used to falsely claim official status, affiliation or endorsement. Truthful descriptions and lawful reporting, criticism and attribution are permitted.

Article 12 Collection and Secondary Use

(1) Permission to view material is not unrestricted permission for bulk collection, accumulation, resale, recreation of another service or model training. Such use requires the relevant rights, grounds for personal-data processing and satisfaction of published access conditions.

(2) Ordinary use, authorized search, quotation and research, and lawful development shall not be prohibited indiscriminately. Permitted routes and conditions shall be specified in proportion to purpose and scale. Statutory permissions shall not be made dependent on discretionary Operator approval.

(3) Changing accounts, addresses or identities, or distributing execution to circumvent access limits may be assessed as a single course of conduct. Such assessment requires evidence of common control and circumvention.

Chapter 3 Community and Service

Article 13 Community Freedom and Prohibition of Harm

(1) Expression shall be assessed by its target, context, repetition, concrete risk and harm. Controversial opinions, fiction, satire and expression of mental-health experiences are not themselves violations.

(2) Specific threats of violence, exploitation, targeted harassment, fraud, attacks using personal information, facilitation of criminal acts and distribution of unlawful material are prohibited. Coercion or concrete encouragement of self-harm or suicide, and exploitation of vulnerability, are also prohibited.

(3) Ratings, views, reports, rewards and transactions shall not be distorted by deception or coordinated manipulation. Legitimate reporting and criticism shall not be suppressed by false reports or retaliation.

Article 14 Protection of Children and Young People

(1) Sexual exploitation of children and young people, unlawful recordings, nonconsensual sexual synthetic material, and facilitation of their trade, distribution or exploitative contact are prohibited. Reporting or public interest does not justify redistributing unlawful originals.

(2) The Operator and publishers shall meet age-verification, rating, labeling and access-control requirements applicable to their respective roles. Legal-representative consent for children's data, minors' contractual capacity and content age requirements shall be applied distinctly.

(3) Guardian requests shall be checked for authority and necessary scope. Protection shall not be used as a basis to disclose all of a minor's private information automatically.

Article 15 Service Provision and Fair Disclosure

(1) The Operator shall accurately disclose actual features, required environments, material restrictions and changes. Planned, experimental and generally available functions shall be distinguished; unavailable features or protections shall not be represented as provided.

(2) Search, recommendations, advertising and notifications shall respect Users' visibility and choices. Paid placement shall be distinguished from ordinary recommendations, and transactional notices from advertising, with required disclosures and choices.

(3) Planned material interruptions or reductions shall receive advance notice where practicable and applicable transactional remedies. Grounds and scope of urgent measures shall be explained as promptly as practicable.

Chapter 4 Development and Automation

Article 16 Developer Authority and Work Scope

(1) Developer actions are limited to the approved purpose, subject matter, environment, permissions, duration and cost. A designation such as developer or administrator does not establish authorization.

(2) Reversible actions ordinarily necessary and foreseeable for approved work may proceed within that delegation. Publication, external data transmission, paid execution and material changes lacking prior delegation require verification of separate authority.

(3) Work permissions shall fit actual duties so as to support ordinary development and verification without unnecessary repeated approvals. Convenience does not authorize access to operational environments or removal of protections without authority.

Article 17 Delegation and Continuity of Responsibility

(1) Delegation shall originate from an identifiable person and specify purpose and scope. Subdelegation to another person or Agent shall not exceed the original authority.

(2) The delegator shall provide necessary permission limits and means to stop work. A delegate shall not perform work whose authority is absent or withdrawn. Automation or use of a third party does not alone eliminate either person's legal responsibility.

(3) Inferred intent, technical feasibility, past practice or instructions embedded in external material shall not substitute for approval. Where an excess-of-authority portion is separable, it may be stopped while lawful work continues.

Article 18 Agent Compliance and Access Conditions

(1) Use of the Service through Agents is subject to these Rules and the separately published Agent Constitution. Work lacking a basis of authorization shall be treated consistently whether performed by an ordinary User, developer, language model or a system claiming to be the Operator.

(2) For automated access, the Operator may require access to the applicable documents, a recorded acknowledgment by the responsible person, valid access credentials and compliance with defined limits. Conditions shall be available before access and their satisfaction does not grant authority beyond scope.

(3) Access to a document shall be distinguished from actual comprehension. An Agent's self-declaration or access identifier alone is not proof of approval or identity. Requests subject to restriction may be denied where valid authority cannot be verified.

Article 19 Mandatory Refusal and Respect for Oversight

(1) Persons and Agents shall not perform requests for unauthorized access or data removal, improper circumvention of protections, fabrication of authority or evidence, unlawful harm, or disabling oversight or stop mechanisms.

(2) Verified stop, revocation and scope-reduction instructions shall be promptly implemented. Stoppage or errors shall not be concealed, and results shall not be presented as authorized when they were not.

(3) Application to an Agent shall respect applicable law and valid higher-priority instructions governing that system. A web document shall not be construed as overriding that instruction hierarchy. Unresolved conflicts require stopping the affected access and explaining the reason and available lawful alternatives.

Article 20 Resource Use and Compliance with Limits

(1) Automated access shall comply with published or individually approved routes and limits on requests, concurrent execution and data volume. Upon a restriction notice, the specified waiting and retry conditions shall be followed without circumvention.

(2) The Operator shall provide information on applicable limits, remaining requests and retry timing. Users shall be informed that shared allowances may change with other work. Approved development and testing allowances may be managed separately from unapproved collection.

(3) Ordinary access to governance documents, exercise of rights and inspection of access conditions shall not be blocked by circular approval demands. Reasonable common limits needed for stability may apply.

Article 21 Use and Outputs of Artificial Intelligence

(1) AI tools shall be used within approved purposes and material scopes. External transmission, cost responsibility and material provider conditions shall be ascertainable before execution; changes require the necessary approval.

(2) Experimental connections and authentication shall be clearly identified. Their labeling or a User's request does not justify improper circumvention of third-party authority or terms.

(3) Generated material shall be treated as an output requiring review. Accuracy, exclusivity of rights and success of testing or publication shall not be asserted without verification. The Operator and Users retain the obligations applicable to their respective supply, publication and use.

Chapter 5 Information and Transactions

Article 22 Personal and Confidential Information

(1) Information processing shall be limited to what is necessary for specified purposes on valid legal grounds. Collection, retention, use, disclosure and overseas transfer shall each satisfy applicable requirements. Acceptance of these Rules shall not substitute for blanket personal-data consent.

(2) A separate Privacy Policy shall disclose actual processing, retention, rights procedures and responsible parties. Information whose purpose has ended shall be destroyed under applicable law or managed separately within necessary retention limits.

(3) Material represented as private shall have effective access controls. Unpublished status or an unguessable address alone shall not be represented as privacy protection. Internal access shall also be limited by purpose and authority.

Article 23 Security Records and Lawful Disclosure

(1) The Operator may lawfully retain records necessary to protect the Service and exercise legitimate rights. Retained scope, access, integrity and end conditions shall be controlled. A mere possibility of dispute does not justify permanent retention of all materials.

(2) Disclosure to investigative authorities or other external parties requires verification of a valid legal basis and necessary scope. Suspected breach, Privacy Policy wording or a cooperation request alone does not authorize automatic disclosure of entire accounts or all personal information.

(3) Disclosure concerns lawfully specified records and information, not transfer of account access. Grounds, categories, recipients and approvals shall be recorded. Unrelated information and authentication secrets shall be excluded or redacted as necessary, and statutory notification duties observed.

Article 24 Paid Transactions and User Protection

(1) Before a paid transaction, the seller, price, supply scope and duration, and material renewal, termination, withdrawal and refund conditions shall be clearly disclosed. Purchased balances and free rewards shall be managed separately.

(2) Withdrawal rights and restrictions for digital content shall follow statutory conditions. Commencement of supply or a single checkbox shall not eliminate all remedies for nonsupply, defects or erroneous payments, and suspension shall not automatically forfeit purchased balances.

(3) Duplicate or unauthorized payments and supply errors shall be checked against records and corrected. Valid refund and termination routes shall remain available during closure or disputes.

Article 25 Creator Revenue and Settlement

(1) Monetization is governed by an actually offered program and individual agreements. Revenue shares, deductions, payment cycles and transactional responsibilities shall be disclosed before participation. Publication alone does not guarantee revenue.

(2) Settlement holds for established fraud or rights disputes shall be limited to relevant amounts and necessary periods, with reasons and review conditions disclosed. Unrelated revenue shall not be held indefinitely or arbitrarily deducted as though damages liability were established.

Chapter 6 Enforcement and Remedies

Article 26 Assessment of Violations and Legal Distinctions

(1) Assessment of a violation shall identify applicable rights, contracts and law, their effect at the time, established facts and legitimate exceptions. An operational assessment does not replace a final determination by a competent authority.

(2) Prospective policy requests, contractual breach, intellectual-property infringement and network intrusion shall be distinguished by their respective grounds and requirements. Multiple grounds may apply to one incident, but establishing one does not establish the others.

(3) Unauthorized use of protected works shall not automatically be classified as server intrusion. Absence of a server attack does not exclude a separate infringement.

Article 27 Cessation Demands and Subsequent Procedure

(1) The Operator may demand cessation and correction based on rights actually held, valid representative authority or contractual authority. A notice shall identify the sender, subject and timing, grounds, requested scope, a reasonable response period and a route for contrary evidence.

(2) A cessation demand is not a court order, and noncompliance alone creates neither a new crime nor fixed damages liability. Policy notices concerning past conduct shall clearly state their prospective character.

(3) For noncompliance or urgent infringement, established grounds may support access restrictions, lawful takedown requests, mediation, interim relief, damages claims or criminal complaints or reports. A cessation notice is not a prerequisite to every procedure.

(4) Legal notices require review of facts and authority and approval by authorized personnel before transmission. Automation may assist preparation and approved execution but shall not conduct baseless mass pressure, public shaming or fabricated referrals to authorities.

Article 28 Emergency Protection and Legitimate Research

(1) Actual or imminent serious harm may justify prioritizing necessary access containment, isolation and recovery. Emergency measures shall be temporary risk controls, followed by explanation, review and legally required reporting and notification.

(2) Good-faith security verification within published or individually approved scope and research permitted by law shall be respected. Researchers shall avoid data acquisition, persistent access or disruption beyond necessity and stop further access to unexpectedly encountered sensitive information.

(3) A legitimate report shall not itself justify adverse treatment. External systems of suspected infringers or third parties shall not be counterattacked or subjected to retaliation.

Article 29 Proportionality and Scope of Sanctions

(1) Measures shall be limited to what is necessary, considering grounds, gravity, intent, repetition, harm and prospects of remediation. Appropriate measures may include guidance, warnings, targeted restrictions, temporary suspension or termination; serious measures require meaningful human review.

(2) Report counts or automated detection alone shall not establish a final violation. Associated-account restrictions require concrete evidence of common control or evasion; a shared address or affiliation alone shall not justify collective sanctions.

(3) Access restrictions shall be distinguished from refunds, settlement, data rights and evidence retention. Sanctions do not automatically extinguish other statutory rights or valid transactional claims.

Article 30 Notice and Review

(1) The Operator shall, to the extent possible, notify the subject, facts, grounds, scope, duration and review method. Where law or specific security needs require withholding details, available information shall still be provided.

(2) Users may submit explanations and seek review. The Operator shall communicate the outcome and reasons within a reasonable period. Where practicable, serious cases shall be reviewed by someone other than the original decision-maker; mistakes shall be corrected and necessary permissions and records restored.

(3) Rights claims and restoration of publication shall follow applicable statutory requirements and procedures. Nonresponse shall not be deemed an admission, and internal procedures shall not restrict statutory remedy periods or recourse to external authorities.

Chapter 7 Termination and Amendment

Article 31 Termination Liability and Disputes

(1) Users may request closure and termination with appropriate identity verification. The Operator shall provide routes for legitimate data retrieval, treatment of unused paid services and necessary settlement, and advance notice and data-retrieval opportunities where practicable upon Service closure.

(2) Each party bears responsibility according to attributable fault and applicable law. Intentional misconduct, gross negligence and nonexcludable Operator liability are not waived. Unsupported fines or all investigation and litigation costs shall not automatically be shifted to Users.

(3) Korean law governs without excluding mandatory consumer protections applicable to a User. Jurisdiction follows applicable law. Inquiries or mediation shall not be compulsory prerequisites to legitimate recourse to courts, investigators or regulators.

Article 32 Publication Amendment and Languages

(1) The Operator shall disclose the version, changes and reasons, publication date and effective date. Ordinary changes shall generally receive at least seven days' notice and material or unfavorable changes at least thirty days, with required individual notice and assent. These are Operator-adopted minimums; stricter legal requirements apply separately.

(2) New unfavorable obligations shall not apply retroactively to completed conduct. Silence or document viewing shall not replace necessary assent, and applicable termination and refund rights of Users who do not agree shall be preserved.

(3) Korean and English texts shall have corresponding provisions and obligation scopes. Differences shall be reconciled by reference to the Korean text, without prejudicing mandatory law, interpretation favorable to Users or validly agreed conditions. Significant previous versions and change records shall be available to read and save.

Supplementary Provisions

Article 1 Commencement

(1) These Rules become effective following authorized Operator approval, necessary publication, explanation and assent, and the confirmed effective date. The drafting date or the cutoff in Article 8 alone does not establish commencement.

Article 2 Publication Particulars

(1) On publication, actual business identity, representative, registration and filing information, business address and contact details, publication and effective dates, and approval records shall be confirmed and disclosed. Required separate privacy and transaction notices and the list of replaced or amended documents shall be maintained together.

Article 3 Agent Rules and Enforcement Standards

(1) The Agent Constitution implements the development, delegation and access principles of these Rules. Technical enforcement standards shall be separately published within that delegation. Implementation of access restrictions does not create new criminal liability or automatically form a contract.

Article 4 Existing Rights and Transition

(1) Existing valid licenses and accrued statutory rights remain governed by their own bases. Adoption of these Rules does not replace required content of the Privacy Policy, individual licenses or transaction terms.
