OPUS

OPUS Terms of Service

These Terms of Service ("Terms") govern use of OPUS (the "Service"). This document is a pre-finalization draft and will be reconciled, after legal review, with Japan's Act on Specified Commercial Transactions, the Consumer Contract Act, Korea's Electronic Commerce Act and Act on the Regulation of Terms and Conditions, and — where applicable — comparable consumer-protection regimes in your jurisdiction.

1. Purpose

These Terms set out the rights, obligations, and responsibilities between the operator of OPUS (the "Company") and users of the Service in connection with OPUS's core offering — the authentication, ownership, and viewing experience of non-reproducible digital artworks — and any ancillary features.

2. Definitions

  • "Service": the website, mobile applications, and any related online features offered under the OPUS brand.
  • "User": any person who consents to these Terms and accesses or uses the Service, including Collectors and Artists.
  • "Artist": a User authorized to list and register digital artworks on the Service.
  • "Collector": a User who acquires, holds, and views Editions.
  • "Edition": an individually authenticated instance of a specific digital artwork, identified by a unique identifier and by records kept in The Chronicle.
  • "The Chronicle": an append-only, integrity-assured ledger recording creation, ownership, and transfer of Editions.
  • "The Vault": a logical private storage zone within operating infrastructure, subject to access control and encryption, in which master assets and sensitive data are kept.
  • "DLT / NFT": distributed-ledger technology (including NFTs) used as a technical means to support uniqueness and provenance. The Service is not offered as an investment or financial product.

3. Effect, Amendment, and Notice of these Terms

  1. These Terms take effect upon posting within the Service. By registering for or continuing to use the Service, you are deemed to agree to these Terms.
  2. The Company may amend these Terms as required by applicable law or reasonable operational need. Amended Terms will be announced in-service or by email at least 7 days before the effective date (or at least 30 days before if the amendment is materially adverse to Users).
  3. If you do not agree with the amended Terms, you may terminate your Service contract before the effective date. Continued use after the effective date constitutes acceptance.
  4. These Terms may be published in Korean, Japanese, and English. In case of interpretive discrepancy, the mandatory consumer-protection laws of your country of residence prevail. Where those do not resolve the discrepancy, the Company may rely on the Korean version as the reference text, provided that this does not restrict any right guaranteed to you by applicable law.

4. Formation of the Service Contract

  1. The Service contract is formed when a prospective User consents to these Terms and the Privacy Policy and creates an account through the procedure set by the Company.
  2. The Company may refuse or subsequently terminate a registration in any of the following cases:
    • The applicant uses another person's name or information without authorization;
    • The applicant's use violates applicable law or is likely to offend public order or morals;
    • Regular service delivery is technically or operationally infeasible.
  3. Users must be at least 16 years of age (or at least 14 years of age for Korean residents). Users below the applicable threshold must follow additional procedures required by law, such as obtaining guardian consent.

5. Account and Security

  1. You are responsible for the security of your account credentials (email, password, linked SSO accounts, etc.).
  2. You must not transfer, lend, or share your credentials with third parties. You accept the consequences of any failure to safeguard credentials, except for harm caused by the Company's failure to exercise reasonable care.
  3. If you suspect unauthorized use of your account, you must notify the Company without delay, and the Company will take appropriate action after verification.

6. Provision and Changes to the Service

  1. The Service is intended to be available 24/7, but may be suspended in whole or in part for scheduled or emergency maintenance, incidents, force majeure, or comparable events.
  2. The Company may change the content, structure, or operation of the Service with reasonable cause. Material changes are announced under Section 3.

7. Issuance, Purchase, and Ownership of Editions

  1. An Edition is an individually authenticated instance of a non-reproducible digital artwork. Purchasing an Edition grants personal rights to view, hold, and transfer that specific Edition, but does not transfer copyright or any commercial-use rights (see Section 9).
  2. The uniqueness, edition count, and ownership history of an Edition are evidenced by The Chronicle and any associated distributed-ledger records.
  3. The Company makes no representation or warranty with respect to the price movement, potential gain, or future transferability of any Edition. The Service is not operated for the purpose of investment or financial-instrument trading.
  4. Minors and persons with limited contractual capacity must comply with procedures required by applicable law (such as obtaining guardian consent) when purchasing an Edition.
  5. Distribution channels and the Company's role. Editions are distributed through two distinct channels, in which the Company's legal position, scope of responsibility, and disclosure obligations differ.
    • Primary — Releases: The channel in which an artist publishes an Edition for the first time through OPUS. In this channel, the Company acts as the merchant of record and sells Editions directly to users; the Company is the party responsible for applicable disclosures (including the Specified Commercial Transactions Act notice referenced in Section 17).
    • Secondary — Provenance: The channel in which a previous custodian seeks a next custodian for an Edition they hold. In this channel, the Company acts as a matching facilitator and the recorder of The Chronicle; the contracting parties are the previous custodian and the next custodian. The Company provides identity verification, Vault eligibility checks, fee settlement, and recording of the transfer, and is not itself the seller of the Edition.
  6. The Company separates the two channels by name, URL, and screen design (Releases at /releases; Provenance at /provenance) so that users do not confuse the two.

8. Payment, Fees, and Refunds

  1. Sale prices of Editions are shown on each product page, with a clear indication of whether consumption or sales tax is included. Available payment methods are those designated by the Company.
  2. The Company may charge transaction fees or similar charges for operating the Service. The type, rate, and calculation method of each fee are disclosed in-service or in an annex to these Terms.
  3. Given the nature of digital content, once payment is completed and the Edition has been recorded in The Chronicle, refunds or cancellations based on change of mind alone may be restricted (see Japan's Act on Specified Commercial Transactions, Enforcement Order Art. 16-3; Korea's Electronic Commerce Act Art. 17(2)(5)). However, the Company will provide refunds or re-delivery — as appropriate under applicable law — in cases such as:
    • The Edition was not properly delivered due to technical failure in payment or delivery;
    • The Edition materially differs from the contract (see Japan Civil Code Art. 562; Korean non-performance doctrine);
    • Any other case where statutory withdrawal rights of the consumer apply.
  4. Specific refund/cancellation procedures and contact points are published on the Service's customer-support page.
  5. For consumers in Japan, the Company implements order-confirmation screens and similar measures aligned with the Electronic Consumer Contract Act to help prevent mistaken orders.

9. Intellectual Property and Licensing

  1. Intellectual property rights in the software, UI, text, logos, and design assets of the Service belong to the Company or its lawful licensors.
  2. Copyright in the underlying artwork of each Edition belongs, in principle, to the Artist.
  3. The Company receives from Artists a non-exclusive, royalty-free (or contractually scoped) license to use the artwork as reasonably necessary to operate the Service — including in-Service display, promotion, previews, thumbnails, and backup.
  4. Collectors who acquire an Edition receive the following non-exclusive personal license:
    • Personal viewing and display within the Service;
    • Display and transfer of ownership state as recorded in The Chronicle.
  5. The license in Section 9.4 does not include:
    • Commercial exploitation (advertising, merchandising, paid re-exhibition, etc.);
    • Creation of derivative works (adaptations, transformations, etc.);
    • Public distribution of the artwork image beyond demonstrating ownership.
  6. Any activity under Section 9.5 requires separate written permission from the Artist.

10. The Chronicle and The Vault

  1. The Company records the issuance, transfer, and ownership state of Editions in The Chronicle in an append-only manner, with hash chaining and similar techniques to preserve record integrity.
  2. Records in The Chronicle serve as the basis for authenticity evidence of an Edition and are used only to the extent reasonably necessary for audit, dispute resolution, and operational integrity.
  3. The Company stores master assets and sensitive data in The Vault or an equivalently controlled environment, applying least-privilege access (RBAC), encryption in transit and at rest, and audit logging. See Privacy Policy §4 for the detailed safeguards.

11. Prohibited Conduct

You must not:

  1. Use another person's name, account, or payment method without authorization;
  2. Interfere with the Service or place abnormal load on it using automated means (bots, scripts, scrapers, etc.);
  3. Attempt reverse engineering, circumvention, or vulnerability probing, or disclose or exploit information obtained thereby;
  4. Engage in market manipulation, fictitious transactions, fraud, or other conduct that impairs fair trading;
  5. Register or distribute content that is illegal, obscene, discriminatory, or that infringes others' rights;
  6. Infringe the copyright or moral rights of Artists, or register third parties' works without permission;
  7. Tamper with, or attempt to tamper with, The Chronicle records;
  8. Engage in any other conduct that the Company reasonably prohibits for operational reasons.

Upon verified violation, the Company may — with prior notice, or with retroactive notice in urgent cases — remove content, restrict features, suspend use, or terminate the contract.

12. Company's Obligations

The Company exercises reasonable care to:

  1. Provide the Service in a stable and continuous manner;
  2. Maintain protection of personal information and transactional security;
  3. Operate customer-support channels capable of addressing reasonable user inquiries and complaints;
  4. Continuously improve an information-security management system aligned with applicable law and recognized standards (such as ISO 27001).

13. Disclaimer and Limitation of Liability

  1. The Company is not liable for suspension or delay of the Service caused by force majeure, communications failure, or user fault — or any event beyond the Company's reasonable control.
  2. The Company is not liable for any expected profit, price-differential gain, or future transfer price of Editions. Consistent with Section 7.3, the Service is not an investment product.
  3. In disputes between Users, the Company's involvement is limited to what is reasonable for a platform operator.
  4. The limitations in this Section 13 do not apply to damages caused by the Company's intentional misconduct or gross negligence, or to any liability that applicable law prohibits from being limited (e.g., Japan Consumer Contract Act Art. 8; Korea Act on the Regulation of Terms and Conditions Art. 7).

14. Personal Information

  1. The Company collects, uses, stores, and disposes of your personal information in accordance with the separately posted Privacy Policy.
  2. Agreeing to these Terms also constitutes agreement to the Privacy Policy.
  3. Cross-border transfers (including to Google LLC) and related disclosures are described in Privacy Policy §6.

15. Termination of the Contract; Discontinuation of the Service

  1. You may request account closure (termination of the Service contract) at any time through Service settings or the support window.
  2. The Company may terminate the contract for material violations of Section 11, or for unavoidable operational reasons, with prior notice — or, in cases of urgent and clear violation, with retroactive notice.
  3. Even after termination, audit and integrity records (such as The Chronicle) may be retained, after de-identification where feasible, as described in Privacy Policy §9.
  4. If the Company discontinues the Service (in whole or in part) for unavoidable reasons, it will give notice at least 30 days in advance and, where required by law, describe alternative means or data-portability options.

16. Dispute Resolution, Governing Law, and Venue

  1. Disputes arising under these Terms or the Service are first addressed through good-faith negotiation.
  2. Users may seek mediation or counseling from consumer-protection authorities, such as Korea Consumer Agency / Korea Consumer Dispute Settlement Commission, Japan's National Consumer Affairs Center / local Consumer Affairs Centers, or equivalent bodies in your jurisdiction.
  3. As to governing law and forum, the mandatory consumer-protection laws of your country of residence apply to the extent they provide protections more favorable to you. Otherwise, the Company and the User agree to submit to [jurisdiction to be specified] as the court of first instance.

17. Jurisdiction-Specific Disclosures

  1. Users resident in Japan: disclosures required by Article 11 of the Act on Specified Commercial Transactions are published at 特定商取引法に基づく表記. That notice applies only to the primary "Releases" channel described in Section 7(5)(i), in which the Company acts as the merchant of record, and does not apply to transactions in the "Provenance" channel described in Section 7(5)(ii). The Company's role in the Provenance channel (matching, recording to The Chronicle, fee settlement) is governed by Section 7 and any separate notice made available in the Service.
  2. Users resident in Korea: business-operator information and terms required by Article 10 of the Electronic Commerce Act are shown in these Terms and in the operator-information panel at the bottom of the Service.

18. Miscellaneous

  1. If any provision of these Terms is held to be invalid or unenforceable under applicable law, the remaining provisions continue in full force and effect.
  2. The Company may transfer its rights and obligations under these Terms to a legitimate successor in connection with a merger, spin-off, or business transfer, with prior notice to Users.
  3. Matters not stipulated in these Terms are governed by applicable law and commercial custom.
