These Terms of Service (these “Terms”) govern your access to and use of the websites, applications, application programming interfaces, and all related services (collectively, the “Service”) operated by METIS, a non-commercial project operated by students in the Republic of Korea (the “Operator,” “we,” “us,” or “METIS”). By creating an account, clicking “I agree,” or otherwise accessing or using the Service, you acknowledge that you have read, understood, and agree to be bound by these Terms, the Privacy Policy, the Community Guidelines, and, where applicable, the Premium (Paid Service) Terms, each of which is incorporated into these Terms by reference. If you do not agree, you must not access or use the Service. Please read the limitation-of-liability and dispute-resolution provisions carefully, as they affect your legal rights.

Article 1 (Purpose)

The purpose of these Terms is to set forth the basic matters governing the relationship between the Operator and Members, including the rights, obligations, and responsibilities of each party, and the conditions of and procedures for use, in connection with the academic-paper archive, search, recommendation, community, learning, and all ancillary services provided by the Operator. These Terms apply to every visitor, registered user, author, institutional user, and paying subscriber, to the extent relevant to such person.

Article 2 (Definitions)

The terms used in these Terms are defined as follows. Terms not defined herein have the meaning given in the relevant statutes, the service notices, or, failing that, general commercial practice. 1. “Member” means any person who has agreed to these Terms, completed registration in accordance with the procedures established by the Operator, and been granted an account. 2. “Visitor” means any person who accesses the Service without holding an account. 3. “Content” means any and all material or information — including papers, abstracts, metadata, datasets, files, comments, replies, community posts, profile information, display names, biographies, images, and links — that is posted, registered, transmitted, or otherwise made available on the Service in the form of text, symbols, voice, sound, images, video, or code. 4. “Archive” means the database in which papers registered by Members are published and made accessible after the Operator's compliance review. 5. “Paid Service” means any premium subscription, institutional license, or other service the Operator provides for a fee. 6. “Points” means the non-monetary, in-service reward units that Members may earn through designated activities and that carry no cash value. 7. “Community Guidelines” means the separate document that elaborates the standards of conduct, categories of prohibited conduct, and the graduated sanctions referenced in these Terms, and that forms an integral part of these Terms with the same binding effect. 8. “Operations Team” means the personnel and organizational unit that performs trust-and-safety, review, and support functions on behalf of the Operator.

Article 3 (Posting and Amendment of the Terms)

1. The Operator posts the contents of these Terms, together with the trade name, the name of the representative, the business address, contact information, and other required operator information, on the initial service screen or a linked screen so that Members may readily review them. 2. The Operator may amend these Terms to the extent that doing so does not violate applicable law, including the Act on the Regulation of Terms and Conditions, the Act on Promotion of Information and Communications Network Utilization and Information Protection (the “Network Act”), the Personal Information Protection Act (the “PIPA”), and the Act on the Consumer Protection in Electronic Commerce (the “E-Commerce Act”). 3. When the Operator amends these Terms, it announces the amended Terms, together with the effective date and the reason for the amendment, at least seven (7) days before the effective date. Where an amendment is unfavorable to Members or material, the Operator announces it at least thirty (30) days in advance and additionally gives individual notice by electronic means such as email or an in-service notification. 4. Where the Operator, in giving notice of an unfavorable amendment, has clearly stated that a Member who does not express refusal by the effective date will be deemed to have consented, and the Member does not expressly refuse by that date, the Member is deemed to have consented to the amended Terms. A Member who does not agree to the amended Terms may terminate the service agreement at any time before the effective date.

Article 4 (Effect, Interpretation, and Supplementary Rules)

1. These Terms, the Privacy Policy, the Community Guidelines, the Premium (Paid Service) Terms, and the operating policies and notices posted within the Service together constitute the entire agreement between the Operator and the Member with respect to the Service. 2. Where a specific matter is regulated more particularly in the Community Guidelines, the Premium Terms, or an individual service notice, that more specific provision prevails for that matter; in all other respects these Terms govern. 3. Matters not provided for in these Terms, and the interpretation of these Terms, are governed by applicable law and general commercial practice.

Article 5 (Formation of the Service Agreement)

1. The service agreement is formed when a person who wishes to register (the “Applicant”) agrees to these Terms, applies for registration in accordance with the procedures established by the Operator, and the Operator accepts the application. 2. The Operator may, in principle, accept an Applicant's registration. However, the Operator may refuse to accept, or may subsequently terminate, an application that falls under any of the following: (a) the Applicant has previously lost membership for breach of these Terms, except where the Operator's re-registration approval has been obtained; (b) the application uses another person's name or information, or contains false information; (c) the Applicant has not provided information requested by the Operator, or has provided it falsely; (d) approval is impossible due to reasons attributable to the Applicant, or the application is made in violation of applicable law or for a purpose that harms public order or good morals; (e) the Applicant is below the eligible age and has not obtained the consent of a legal representative as required by Article 6. 3. The Operator may withhold acceptance until the reason is resolved where there is no room in the service-related facilities, or where there is a technical or business impediment.

Article 6 (Eligibility; Minors and Consent of a Legal Representative)

1. METIS is used by a community that includes student researchers; the Service therefore knowingly admits minors subject to the safeguards in this Article and the Privacy Policy. 2. A child under the age of fourteen (14) may register only where the consent of a legal representative (guardian) has been obtained in accordance with Article 22-2 of the PIPA. The Operator operates a verification procedure — including collection of the guardian's name, relationship, and email and an email one-time-password verification — to confirm that such consent has been given, and records the date, time, and IP address of the verification as evidence. 3. For users located outside the Republic of Korea, additional age thresholds may apply under local law (for example, the U.S. Children's Online Privacy Protection Act for children under 13, and the EU/UK General Data Protection Regulation for children under the age set by the relevant Member State, typically 13 to 16). The Operator applies the higher protective standard where required. 4. A legal representative may, at any time, exercise the rights of the child, withdraw consent, and request suspension, correction, or deletion of the child's account and personal information. 5. If the Operator becomes aware that an account was created by a child without the required consent, it may suspend or delete the account and the associated personal information after notice to the extent practicable.

Article 7 (Account Registration, Identity Signals, and Verification)

1. Registration requires a valid email address, a password, and a display name, and requires the Applicant to confirm their date of birth for age verification. The Operator may additionally offer or require email, phone (SMS), institutional-email, or federated (OAuth) verification. 2. Optional verification features — including institutional (school) verification by academic email domain, phone-number verification, and connection of third-party identity providers — are provided to enhance trust and account security. A Member is responsible for ensuring that any information submitted is true, accurate, current, and lawfully theirs to provide. 3. A single natural person may not maintain multiple accounts for the purpose of evading sanctions, manipulating engagement metrics, or otherwise circumventing these Terms. 4. The Operator may refuse, suspend, or revoke a verification status that is found to be based on false, fraudulent, or expired information.

Article 8 (Account Security and Credential Management)

1. The Member is responsible for managing their account and authentication credentials with the care of a good manager, and may not allow a third party to use them. 2. The Operator offers multiple security mechanisms, which Members are strongly encouraged to enable, including one-time-password email or SMS verification, time-based one-time-password two-factor authentication, FIDO2/WebAuthn passkeys, and trusted-device management. The Member is responsible for safeguarding the devices and authenticators associated with these mechanisms. 3. The Member must immediately notify the Operator and follow its guidance upon becoming aware that their account has been stolen or is being used by a third party. 4. The Operator is not liable for any disadvantage arising from the Member's failure to give the notice in the preceding paragraph or to follow the Operator's guidance, except where caused by the Operator's intent or gross negligence.

Article 9 (Members' Obligations and Prohibited Conduct)

1. A Member must comply with applicable law, these Terms, the Community Guidelines, the service notices, and matters notified by the Operator, and must not interfere with the stable operation of the Service. 2. A Member must not engage in any of the following, the detailed standards and graduated sanctions for which are set out in the Community Guidelines: (a) infringing the copyright, patent, trademark, or other intellectual-property rights of others; (b) research misconduct, including plagiarism, fabrication or falsification of data, improper authorship, and improper duplicate publication; (c) defaming, insulting, harassing, stalking, or threatening others, or expressing hatred or discrimination; (d) collecting or disclosing another person's personal information without consent; (e) posting obscene material, unlawfully filmed material, or any sexual material involving minors, or making inappropriate contact with a minor (grooming); (f) advertising or promoting for commercial purposes without the Operator's prior consent, spamming, or manipulating recommendation, view-count, or like metrics; (g) interfering with the stable operation of the Service, including mass access by automated means, exploitation of vulnerabilities, and circumvention of sanctions through multiple accounts; (h) posting or relaying information whose distribution is prohibited by law, or instigating, abetting, conspiring in, or announcing a crime; (i) any other act that violates applicable law, these Terms, or the Community Guidelines. 3. The Member bears civil and criminal responsibility for their own acts; the Operator's self-regulatory measures are separate from, and do not determine, such responsibility.

Article 10 (Submission, Review, and Publication of Papers)

1. A Member may apply to register only papers in which the Member holds legitimate rights, and, for joint works, warrants that the consent of all joint authors has been obtained. 2. A submitted paper undergoes the Operator's compliance review — covering research-ethics disclosure, plagiarism, infringement of third-party rights, declaration of the use of generative artificial intelligence, and violation of law — before a decision on publication is made. The Operator makes the review standards and procedures available within the Service. 3. The Operator may refuse publication, or may make a paper private or delete it after publication, where (a) research misconduct is confirmed or reasonably suspected; (b) a violation of law or an infringement of a third party's rights is confirmed; or (c) a false entry in an ethics-disclosure field is confirmed. 4. Review is a procedural and compliance screening for the integrity and safety of the Archive; it is not a peer-review certification of scientific validity, and publication does not constitute the Operator's endorsement of a paper's academic content.

Article 11 (Research Integrity and Compliance)

1. The Member warrants that each submission is the product of honest research, that data have not been fabricated, falsified, or improperly selected, that all sources are appropriately cited, and that any use of generative artificial intelligence has been disclosed as required. 2. Where research misconduct is alleged, the Operator may suspend visibility of the paper as an interim measure, request explanation from the author, consult external experts, and, where appropriate, notify the author's affiliated institution or the relevant academic society. 3. A finding of misconduct may result in retraction, correction, or an expression of concern being affixed to the paper, forfeiture of any improperly obtained Points or status, and sanctions under the Community Guidelines.

Article 12 (Content Rights and Open Licenses)

1. Copyright and other intellectual-property rights in Content posted by a Member remain with that Member or the rightful rights holder. 2. The scope of third-party use of a paper is governed by the license the Member selects upon publication (for example, a Creative Commons license such as CC BY 4.0). The Member is responsible for understanding the legal effect of the chosen license and for ensuring that the Member is entitled to grant it. 3. A license, once granted to the public for a published paper, may be irrevocable as to copies already distributed under it; the Member should select a license accordingly.

Article 13 (Versioning, Correction, and Retraction)

1. Edits to a published paper are governed by the version-management policy; a material revision may be subject to re-review. 2. To preserve the integrity and citation stability of the scholarly record, arbitrary deletion of a published paper may be restricted. In such case the Operator provides alternative measures in accordance with scholarly practice, such as a retraction or correction notice, rather than erasure. 3. Withdrawal of membership disconnects the account from a published paper; however, attribution of authorship may persist in accordance with scholarly practice and the selected license.

Article 14 (License Granted to the Operator)

1. By posting Content, the Member grants the Operator a worldwide, non-exclusive, royalty-free, sublicensable (solely to the Operator's processors acting on its behalf) license to host, store, reproduce, cache, transmit, publicly display, adapt for formatting and accessibility, index, and distribute the Content, solely to the extent necessary to operate, display, search, recommend, secure, promote, and improve the Service and to preserve the scholarly record. 2. This license also permits the Operator to use Content, in de-identified or pseudonymized form, for statistical, scientific-research, and service-improvement purposes, including the training and evaluation of recommendation and safety systems, subject to the Privacy Policy. 3. This license terminates when the Content is deleted or the Member withdraws, except that (a) residual copies may persist for a limited period in backups or caches for technical reasons; (b) the license continues as necessary for copies a third party has lawfully made under an open license the Member selected; and (c) the license continues as necessary to comply with law or to preserve the scholarly record. 4. The Member waives no moral rights that are non-waivable under applicable law; this license does not transfer ownership of the Content.

Article 15 (Intellectual Property of the Operator)

1. All rights in the Service itself — including software, source code, databases, design, user interface, the METIS name and logo, and other marks — belong to the Operator or its licensors and are protected by intellectual-property law. Except as expressly permitted, a Member may not copy, modify, distribute, sell, lease, create derivative works from, reverse-engineer, or commercially exploit any part of the Service without the Operator's prior written consent. 2. The Operator grants the Member a limited, revocable, non-exclusive, non-transferable license to access and use the Service for the Member's own non-commercial, lawful use in accordance with these Terms.

Article 16 (Feedback)

Where a Member submits suggestions, ideas, or other feedback regarding the Service, the Operator may freely use such feedback without restriction and without any obligation of compensation, attribution, or confidentiality, and the Member grants the Operator a perpetual, irrevocable, royalty-free license to do so.

Article 17 (Points and Virtual Rewards)

1. Points are awarded for designated activities (for example, registering a paper, receiving likes or bookmarks, daily sign-in, and writing comments or posts) in accordance with the rules published within the Service. 2. Points are a promotional, in-service convenience, carry no cash value, are not a means of payment, prepaid electronic payment instrument, or property right, and cannot be exchanged for cash, transferred, sold, gifted, or inherited, except where expressly permitted by the Service. 3. The Operator may adjust the earning and redemption rules of Points for legitimate operational reasons; where a change is unfavorable to Members, the Operator gives advance notice in accordance with Article 3. Points obtained through error, abuse, manipulation, or sanctioned conduct may be cancelled or recovered. 4. Unredeemed Points may expire upon withdrawal of membership or after a period of account dormancy, as published within the Service.

Article 18 (Paid Services, Billing, Auto-Renewal, and Institutional Licenses)

Paid Services are not currently operated; the following provisions apply if and when the Operator introduces a Paid Service, at which time the Operator will give prior notice and complete any registration then required by law. 1. The fees, billing methods, billing cycle, renewal terms, and other conditions of Paid Services are set out in the Premium (Paid Service) Terms and the in-service notices. The Service may offer payment by Points, by recurring card billing through a domestic payment-gateway provider, or by an overseas payment provider, and may offer institutional (school) licenses that confer premium benefits on a sponsoring institution's members. 2. Where a subscription is set to renew automatically, it renews for successive periods at the then-current fee until cancelled, and the Member authorizes the Operator and its payment processor to charge the Member's designated payment method at the start of each period. The Operator gives advance notice of any fee change in accordance with Article 3 and applicable law. 3. The Member may cancel a subscription at any time through the settings menu or customer inquiry; cancellation stops future renewals and takes effect at the end of the current paid period, subject to the withdrawal and refund rules in Article 19. 4. Institutional licenses are subject to a separate agreement; benefits granted through an institution end when the institution's license expires or is terminated.

Article 19 (Right of Withdrawal, Cooling-Off, and Refunds)

These provisions apply where a Paid Service is offered. 1. The Operator handles withdrawal of a subscription (cooling-off) and refunds in accordance with the E-Commerce Act and other applicable consumer-protection law. In principle, a consumer may withdraw a subscription within seven (7) days of the contract or of the date the service becomes available. 2. The right of withdrawal may be limited where provision of the digital content or service has begun with the consumer's prior consent, to the extent permitted by law; in such case the Operator, before obtaining consent, indicates the restriction and provides a means to confirm it, failing which the right of withdrawal is not restricted. 3. For periodic subscriptions, the Operator refunds the unused portion in accordance with applicable law and the Premium Terms after deducting amounts already used and any benefits already provided. 4. Where a minor Member has entered into a paid contract without the consent of a legal representative, the minor or the legal representative may cancel the contract in accordance with the Civil Act.

Article 20 (Third-Party Services, Integrations, and Links)

1. The Service integrates with, links to, or relies upon third-party services — including cloud infrastructure, content-delivery and security networks, payment providers, messaging providers, image-moderation providers, federated-login providers, and a Discord community integration — each of which is governed by that third party's own terms and privacy policy. 2. The Operator is not responsible for the content, products, policies, or practices of third parties, and a Member's dealings with a third party are solely between the Member and that third party. The Operator's use of processors is described in the Privacy Policy. 3. Linking to the Service from an external site, or framing the Service, in a manner that is misleading, infringing, or harmful is prohibited.

Article 21 (Rights-Holder Requests, Notice-and-Takedown, and Counter-Notice)

1. Where Content infringes copyright, trademark, privacy, reputation, or another right, or violates the Network Act, the Copyright Act, or other law, the rights holder may request suspension of publication and deletion in accordance with the procedures prescribed by law, and the Operator takes measures accordingly. 2. Even absent a rights-holder request, where there is reason to recognize an infringement of rights or a violation of the Operator's policies or applicable law, the Operator may take interim measures such as temporarily blocking the Content. 3. A Member whose Content has been blocked may submit a counter-notice or objection; the Operator reviews the objection and decides whether to maintain or restore the Content. The Operator operates a repeat-infringer policy and may terminate the account of a Member who repeatedly infringes the rights of others.

Article 22 (Management of Posts and Interim Measures)

1. The Operator may take interim measures, including temporary blocking (blinding), where Content is reported or recognized as infringing the rights of others or as manifestly unlawful, before a final determination, reflecting the purpose of the interim-measure regime under the Network Act. 2. Where irreparable harm is feared — such as exposure of personal information, unlawfully filmed material, or material harmful to minors — the Operator may take immediate interim measures regardless of whether a report has been received.

Article 23 (Provision, Modification, and Suspension of the Service)

1. The Operator provides the Service 24 hours a day, year-round, in principle. However, it may temporarily suspend all or part of the Service for system maintenance, expansion, or replacement, for communication failures, or for other substantial operational reasons, with prior announcement; where prior announcement is impossible for unavoidable reasons, it may announce afterward. 2. The Operator may change the content of the Service and, for a material change, announces it in advance. 3. The Operator may change or discontinue all or part of a free service in accordance with its policy. In such case it announces the change at least thirty (30) days in advance and, for paying users, provides a reasonable remedy such as a pro-rata refund for the remaining period.

Article 24 (Use Restrictions, Suspension, and Termination)

1. Where a Member breaches these Terms or the Community Guidelines, the Operator may apply, in a graduated or immediate manner according to the gravity of the breach, measures including a warning, deletion of posts, restriction of features, temporary suspension of use, and permanent suspension of use; the specific standards follow the sanctions table of the Community Guidelines. 2. When imposing a sanction, the Operator notifies the Member of the reason and the period, and the Member may file an objection within fifteen (15) days of the notice. The Operator replies with the result within fifteen (15) days of receiving the objection. 3. For conduct falling within the most serious tier of the sanctions table (including sexual exploitation of, or grooming of, minors, distribution of unlawfully filmed material, and attacks on the system), the Operator may impose the highest-level sanction immediately without prior warning and report the matter to the relevant authorities.

Article 25 (Withdrawal of Membership)

1. A Member may apply to terminate the service agreement (withdraw) at any time through the settings menu or customer inquiry, and the Operator processes it without delay in accordance with applicable law. 2. Withdrawal may be held pending where a review, dispute, or payment matter is in progress, until that matter is resolved. 3. Upon withdrawal, the Operator deletes or anonymizes the Member's personal information in accordance with the Privacy Policy, except information that must be retained under applicable law or for the preservation of the scholarly record, and except during any grace period the Service provides to allow recovery of an account deleted in error.

Article 26 (Disclaimer of Warranties)

1. The Service and all Content are provided “as is” and “as available.” To the maximum extent permitted by applicable law, the Operator disclaims all warranties, whether express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, and uninterrupted or error-free operation. 2. The Operator does not warrant the accuracy, reliability, completeness, or legality of Content (including papers) posted by Members; responsibility for the academic content of a paper rests with its author. A Member relies on Content at the Member's own discretion and risk. 3. Nothing in this Article excludes or limits any warranty or liability that cannot be excluded or limited under applicable mandatory law, including consumer-protection law.

Article 27 (Limitation of Liability)

1. The Operator is exempt from liability where it cannot provide the Service due to force majeure such as a natural disaster, war, or the suspension of service by a telecommunications carrier. 2. The Operator is not liable for an impediment to the use of the Service that is attributable to reasons on the Member's part. 3. The Operator is not liable for damage arising from a Member's reliance on Content, or from disputes between Members or between a Member and a third party arising through the Service, except where caused by the Operator's intent or gross negligence. 4. To the maximum extent permitted by law, the Operator's aggregate liability arising out of or relating to the Service is limited, for a paying Member, to the amount the Member paid to the Operator during the three (3) months preceding the event giving rise to the liability and, for a non-paying Member, to a reasonable amount; and the Operator is not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits or data. 5. Nothing in this Article limits liability arising from the Operator's intent or gross negligence, liability for death or personal injury caused by negligence, or any other liability that may not be limited under applicable mandatory law. The limitations apply only to the extent permitted by the law applicable to the Member.

Article 28 (Indemnification)

Where a Member causes damage to the Operator or to a third party by breaching these Terms or applicable law in connection with the use of the Service, the Member is responsible for indemnifying the Operator and holding it harmless against claims, damages, losses, and reasonable expenses arising therefrom, except to the extent the damage is attributable to the Operator's intent or gross negligence.

Article 29 (Protection of Personal Information)

The Operator complies with the PIPA, the Network Act, and other applicable law to protect Members' personal information. Matters concerning the processing of personal information are governed by the separate Privacy Policy, which forms an integral part of these Terms.

Article 30 (Notices to Members)

1. Unless these Terms provide otherwise, the Operator may give notice to a Member by the email registered by the Member or by an in-service notification. 2. For a notice to all Members, the Operator may substitute individual notice by posting on the service notice board for at least seven (7) days; however, it gives individual notice of matters that have a material effect on the Member's own transactions.

Article 31 (Assignment)

A Member may not transfer or assign their rights or obligations under these Terms without the Operator's prior written consent. The Operator may assign these Terms, in whole or in part, in connection with a merger, acquisition, reorganization, or transfer of business, with notice to Members; such assignment does not diminish the rights Members hold under applicable mandatory law.

Article 32 (Severability, No Waiver, and Entire Agreement)

1. If any provision of these Terms is held invalid or unenforceable, that provision is modified to the minimum extent necessary, or severed, and the remaining provisions remain in full force. 2. The Operator's failure to exercise or enforce any right or provision is not a waiver of that right or provision. 3. These Terms, together with the documents incorporated by reference, constitute the entire agreement between the parties regarding the Service and supersede prior agreements on the same subject.

Article 33 (Force Majeure)

Neither party is liable for a failure or delay in performance (other than a payment obligation) caused by an event beyond its reasonable control, including a natural disaster, epidemic, war, act of terrorism, civil disturbance, governmental action, labor dispute, power or telecommunications failure, or failure of a third-party infrastructure provider.

Article 34 (Export Controls and Sanctions)

The Member represents that the Member is not located in, and is not a national of or controlled by, a country or person subject to applicable export-control or economic-sanctions law that would prohibit the Member's use of the Service, and the Member agrees to comply with such law in using the Service.

Article 35 (Governing Law and Jurisdiction)

1. These Terms and any dispute between the Operator and a Member are governed by the laws of the Republic of Korea, without regard to conflict-of-laws principles. 2. Any litigation concerning a dispute between the Operator and a Member is brought before the court having jurisdiction under the Civil Procedure Act of the Republic of Korea. 3. This Article applies to Members residing abroad; however, it does not deprive a consumer of the protection of the mandatory provisions of the law of the consumer's country of habitual residence.

Article 36 (Dispute Resolution and Mediation Bodies)

The Operator operates customer-inquiry channels to resolve disputes with Members amicably. Where a dispute is not resolved amicably, a Member may apply for mediation to a relevant body, including the Content Dispute Resolution Committee, the Korea Consumer Agency, the Korea Consumer Dispute Settlement Commission, and the Personal Information Dispute Mediation Committee. This Article does not restrict a Member's right to judicial remedy.

Article 37 (Operator Information)

Operator: METIS — a non-commercial project operated by students in the Republic of Korea. Contact: admin@metis.re.kr. METIS is operated on a non-commercial basis and is not an incorporated entity or a registered business; accordingly, a business-registration number and a mail-order-business registration number do not apply. If the Operator later offers paid services or otherwise becomes subject to a registration requirement, it will complete the required registration and post the corresponding operator details on the relevant service screen. Members are encouraged to use the in-service customer inquiry for the fastest response.

Addenda

Article 1 (Effective Date) These Terms take effect on 1 January 2026. The amendments reflected in Version 3.0 were announced on 16 June 2026 and take effect on 16 July 2026 (a 30-day advance-notice period). Article 2 (Transitional Measures) These Terms apply to Members who registered before their effective date; however, they do not affect rights or obligations already accrued under the previous Terms. Article 3 (Relationship to Other Rules) Matters not provided for in these Terms are governed by the Community Guidelines, the Privacy Policy, the Premium Terms, and applicable law.

Language and Prevailing Version

These Terms are provided in multiple languages. The English version is the drafting reference. The Korean version is the legally governing version for the Operator's operation in the Republic of Korea; where a translation conflicts with the Korean version, the Korean version prevails, except to the extent the mandatory law of a Member's country of residence requires otherwise.
