1. Acceptance of Terms

By creating an account, accessing, or using the Opus platform ("Service"), you acknowledge that you have read, understood, and agree to be bound by these Terms of Service, our Privacy Policy, and any additional terms, policies, or guidelines referenced herein (collectively, the "Agreement"). If you are entering into this Agreement on behalf of an organisation, company, or other legal entity, you represent and warrant that you have the authority to bind that entity to this Agreement, and the terms "you" and "your" shall refer to such entity.

If you do not agree to this Agreement in its entirety, you must not access or use the Service. Your continued use of the Service after any modifications to these Terms constitutes your acceptance of those changes.

Electronic Agreement: By clicking "I Agree", "Sign Up", or by accessing or using the Service, you consent to entering into this Agreement electronically, and you acknowledge that this electronic agreement has the same legal force and effect as a written, physically signed agreement.

13. Dispute Resolution & Class Action Waiver

We want to resolve disputes fairly and quickly. Please read this section carefully as it affects your legal rights.

• Informal Resolution: Before initiating any formal dispute proceeding, you agree to first contact us at [email protected] and attempt to resolve the dispute informally for at least 60 days. Most disputes can be resolved through good-faith negotiation.
• Mediation: If informal resolution is unsuccessful, either party may refer the dispute to mediation administered by the Resolution Institute of Australia (or a mutually agreed mediation service) before commencing any court proceedings. The costs of mediation shall be shared equally by the parties.
• Jurisdiction: Any disputes not resolved through mediation shall be subject to the exclusive jurisdiction of the courts of Queensland, Australia. Both parties consent to the personal jurisdiction of such courts and waive any objection to venue.
• Class Action Waiver: TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, YOU AND TRINITY DAO PTY LTD AGREE THAT ANY DISPUTE RESOLUTION PROCEEDINGS WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. YOU WAIVE ANY RIGHT TO PARTICIPATE IN A CLASS ACTION LAWSUIT OR CLASS-WIDE ARBITRATION AGAINST TRINITY DAO PTY LTD. If this class action waiver is found to be unenforceable, then the entirety of this dispute resolution section shall be null and void.
• Time Limitation: You agree that any claim or cause of action arising out of or related to your use of the Service or these Terms must be filed within one (1) year after such claim or cause of action arose, or be forever barred, to the extent permitted by applicable law.

14. Termination

Either party may terminate this Agreement:

• By You: You may cancel your subscription and close your account at any time through the Service settings or by contacting us. Cancellation takes effect at the end of the current billing period. No refunds are provided for the remaining portion of a billing period.
• By Us: We may suspend or terminate your access to the Service immediately, without prior notice or liability, if: (a) you breach any provision of these Terms; (b) you fail to pay applicable fees; (c) we reasonably believe your use poses a risk to the Service, other users, or third parties; (d) we are required to do so by law; or (e) we discontinue the Service.
• Effect of Termination: Upon termination, your right to access and use the Service ceases immediately. You will have 30 days to export Your Data after termination (the "Export Period"). After the Export Period, we may permanently delete Your Data from our active systems. We are not obligated to maintain or provide any of Your Data after the Export Period.
• Outstanding Obligations: Termination does not relieve you of any obligation to pay fees incurred prior to termination.

Cryptographic attestation records created through the Veritas Document Management System persist permanently regardless of account termination as described in Section 23.

15. Governing Law

These Terms are governed by and construed in accordance with the laws of the Commonwealth of Australia and the State of Queensland, without regard to conflict of law principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply to these Terms.

To the extent that any lawsuit or court proceeding is permitted under these Terms, you and Trinity DAO Pty Ltd agree to submit to the exclusive personal jurisdiction of the courts located in Queensland, Australia, for the purpose of litigating any dispute. Both parties consent to the personal jurisdiction of such courts and waive any objection to venue.

16. Force Majeure

Neither party shall be liable for any failure or delay in performing its obligations under these Terms (except for payment obligations) where such failure or delay results from circumstances beyond the reasonable control of that party, including but not limited to: acts of God, natural disasters, pandemics, epidemics, war, terrorism, riots, civil unrest, government actions or orders, embargoes, sanctions, labour disputes, strikes, fire, flood, earthquake, power outages, internet or telecommunications failures, cyberattacks, denial-of-service attacks, failure of third-party services or infrastructure, or changes in applicable law or regulation. The affected party shall use commercially reasonable efforts to mitigate the impact and resume performance as soon as practicable.

17. Changes to Terms

We reserve the right to update or modify these Terms at any time at our sole discretion. When we make changes:

• We will update the "Last Updated" date at the top of this page.
• For material changes, we will provide notice through the Service (e.g., a banner notification, in-app alert, or email to your registered address) at least 30 days before the changes take effect.
• Your continued use of the Service after the effective date of any changes constitutes your acceptance of the revised Terms. If you do not agree with the updated Terms, your sole remedy is to discontinue use of the Service and close your account.
• For non-material changes (such as clarifications, formatting, or typographical corrections), we may update these Terms without prior notice.

18. General Provisions

• Entire Agreement: These Terms, together with the Privacy Policy and any other policies or agreements referenced herein, constitute the entire agreement between you and Trinity DAO Pty Ltd regarding the Service and supersede all prior and contemporaneous agreements, proposals, representations, and understandings, whether written or oral.
• Severability: If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, such provision shall be modified to the minimum extent necessary to make it valid, legal, and enforceable, or if modification is not possible, shall be severed from these Terms. The remaining provisions shall continue in full force and effect.
• No Waiver: Our failure to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver of any provision of these Terms will be effective only if in writing and signed by us.
• Assignment: You may not assign, transfer, or delegate your rights or obligations under these Terms without our prior written consent. We may assign our rights and obligations under these Terms without restriction, including in connection with a merger, acquisition, reorganisation, or sale of assets.
• No Third-Party Beneficiaries: These Terms do not create any third-party beneficiary rights. Nothing in these Terms is intended to confer any rights or remedies upon any person other than the parties hereto.
• Relationship of Parties: Nothing in these Terms creates a partnership, joint venture, agency, franchise, or employment relationship between you and Trinity DAO Pty Ltd. Neither party has authority to bind the other or incur obligations on the other's behalf.
• Notices: We may provide notices to you via email to the address associated with your account, through in-app notifications, or by posting on the Service. You may provide notices to us by emailing [email protected]. Notices are deemed received when sent by email or posted on the Service.

• Government Users: If you are a government entity or are using the Service on behalf of a government entity, you acknowledge that the Service constitutes "commercial computer software" and is provided with restricted rights as applicable under government procurement regulations.

20. Veritas Document Management System

Opus provides an optional document management feature called the Veritas Document Management System ("Veritas DMS"), which allows you to store encrypted documents, create cryptographic attestation records, and share verified document access with authorised parties. Use of Veritas DMS is subject to this Section 20 and Sections 21–24.

• How Veritas DMS works: When you upload and attest a document through Veritas DMS: (a) the document is encrypted before being stored; (b) an attestation record is created containing a cryptographic hash of the document, your identifier, a timestamp, and a digital signature — this record links you to the document at a specific point in time; (c) attestation records are periodically consolidated into a Merkle tree structure, creating a tamper-evident chain of all attestations; and (d) the encrypted document and attestation records are stored on our infrastructure and may be additionally backed up to secure cloud storage.
• Access control: Documents attested in Veritas DMS are stored encrypted and are accessible only to: (a) your Opus account users; (b) parties you explicitly grant access to via an Access Grant (see Section 21); and (c) Opus technical staff for platform maintenance and support purposes only.
• Verified document sharing: You may grant time-limited, read-only access to specific attested documents to external parties — such as banks, insurers, councils, or clients — through the Veritas DMS Access Grant feature. Each Access Grant specifies: the document, the recipient, the permitted access level (view or download), and the expiry period. Access Grants are revocable at any time before expiry, but revocation does not affect the permanence of the underlying cryptographic attestation record (see Section 23).
• Veritas DMS pricing: Access to Veritas DMS features is subject to the attestation credit allocation included in your subscription tier, or credits purchased separately. Access Grant fees apply for sharing documents with external parties and are set out in the current Opus pricing schedule.
• Professional use: Veritas DMS is designed to support professional services use cases, including engineering and compliance reports, inspection certificates, site monitoring data, and due diligence documentation. You are solely responsible for ensuring that your use of Veritas DMS complies with any professional licensing requirements, obligations to clients, and applicable laws governing the sharing of professional documents.

21. Verified Document Access Licensing

This section governs how document access is granted to third parties through Veritas DMS and the commercial relationship between you, access recipients, and Opus.

• Opus's role: When you grant a third party access to an attested document through Veritas DMS ("Recipient Access"), you are licensing access to that document directly to the recipient. Opus acts solely as the platform facilitating the technical delivery of that access. Opus is not a party to any agreement between you and the recipient regarding the document's contents or use.
• No endorsement by Opus: Opus does not own, verify, endorse, certify, or take any responsibility for the accuracy, completeness, currency, or professional validity of any document attested and shared through Veritas DMS. Opus provides cryptographic attestation infrastructure only — it confirms that a specific document existed in an unaltered state at a specific time, and nothing more.
• What the recipient receives: A recipient granted access receives: (a) a time-limited right to view and/or download the specific document as specified in the Access Grant; (b) access to the cryptographic attestation record confirming the document hash, attester identity, and timestamp; and (c) access to verification tools to independently confirm the document has not been altered since attestation. The recipient does not receive any warranty, guarantee, or professional certification from Opus regarding the document's contents.
• Access Grant fees: Fees for Recipient Access Grants are charged to the account holder granting access (you), not to the recipient, unless otherwise agreed in writing. Fees are set out in the current Opus pricing schedule and are non-refundable once an Access Grant is created and the access link has been delivered to the recipient.
• Revocation: You may revoke an Access Grant at any time before its expiry. Revocation withdraws the recipient's ability to access the document through the Opus interface. Revocation does not delete the cryptographic attestation record (see Section 23). No refund is provided for early revocation of a paid Access Grant.
• Recipient obligations: Where a recipient accesses a document through a Veritas DMS Access Grant, the recipient must not re-share, redistribute, or sub-license access to the document without your explicit written permission. Opus is not responsible for enforcing this obligation against recipients.

22. Document Accuracy & Attester Liability

The integrity of the Veritas DMS depends entirely on attesters accurately representing the documents they submit. This section sets out the professional responsibilities and liability of any person or organisation that attests a document through Veritas DMS.

• Professional responsibility: Where a document attested through Veritas DMS represents a professional opinion, assessment, inspection report, monitoring dataset, or certification (including but not limited to structural assessments, geotechnical reports, compliance certificates, and environmental monitoring data), the attesting professional or organisation bears sole responsibility for: (a) the accuracy and completeness of the document's contents; (b) compliance with applicable professional standards and licensing requirements governing the production and distribution of such documents; and (c) any reliance placed on the document by recipients or other third parties.
• Accuracy warranty: You warrant that each document you attest through Veritas DMS accurately represents the work, observation, assessment, or opinion it purports to contain as of the date of attestation. Backdating of attestations — that is, attesting a document as of a date other than the actual date on which the attestation is created — is strictly prohibited and may constitute fraud.
• No third-party personal information without authority: You warrant that any document you attest through Veritas DMS does not contain the personal information of any third party (including property occupants, clients, or members of the public) unless: (a) that party has provided explicit written consent to such disclosure; or (b) you are independently legally authorised to process and disclose such information under the Australian Privacy Act 1988 (Cth) or applicable law.
• Intellectual property: You warrant that you hold all necessary rights, licences, consents, and permissions to attest and share any document through Veritas DMS, including rights to any intellectual property, drawings, specifications, data, or third-party content contained in the document.
• Attester indemnity: You indemnify and hold harmless Trinity DAO Pty Ltd, its directors, officers, employees, related bodies corporate, and agents against all losses, claims, damages, penalties, fines, and expenses (including reasonable legal fees) arising from: (a) any inaccuracy, misrepresentation, or omission in any document you attest; (b) any unauthorised personal information contained in a document you attest; (c) any third-party intellectual property claim relating to content you attest; (d) any professional negligence claim by a recipient or third party who relied on a document you attested; or (e) your breach of any professional licensing obligation in connection with a document you attest through Veritas DMS.
• No verification by Opus: Opus does not review, audit, or verify the professional credentials of attesters, nor the accuracy of any attested document's contents. The cryptographic attestation records Opus creates confirm only the identity of the attester, the timestamp of attestation, and the integrity of the document's content at the time of attestation — not the truth or accuracy of that content.

23. Blockchain Immutability & No Right of Erasure for Attested Records

• What is permanent: The cryptographic hash, attester identity, and timestamp recorded in the Merkle attestation chain are permanent. The hash alone does not reveal the document's contents — it is a one-way mathematical function — but it permanently records that a document with that exact content was attested by you at that time. This is the technical basis for tamper-evidence.
• What is not permanent: The document's content (the actual file) is stored separately from the attestation record. The document content can be deleted from active storage upon a valid request. After deletion of the document content, the attestation record continues to exist as a hash — anyone who independently holds a copy of the original document can verify the hash still matches, but access through Opus will be revoked.
• Permissioned network: The Veritas distributed ledger currently operates as a permissioned, closed network. Records anchored to the ledger are not publicly readable. This does not affect the permanence of records — permissioned distributed ledgers are tamper-evident across multiple independent infrastructure nodes within the Trinity DAO group, providing the same immutability guarantee as a public blockchain while restricting read access to authorised parties only.
• Effect of account termination: Termination of your Opus account does not delete cryptographic attestation records created through Veritas DMS. All Access Grants associated with your account will be revoked upon termination. Attested document content will be handled in accordance with our data retention policy and your termination export rights under Section 14.

24. Veritas Network & Internal Token Operations

• Veritas Network: The Veritas DMS is powered by a distributed ledger infrastructure ("Veritas Network") operated by Trinity DAO Pty Ltd and its related entities. The Veritas Network currently operates as a permissioned, closed network — access to write records to the network is restricted to authorised Trinity DAO group entities only. Opus users interact with the Veritas DMS through the Opus platform interface; they do not directly interact with the underlying network infrastructure.
• Internal operational unit: The Veritas Network uses an internal operational unit called VERITAS to record and settle attestation transactions between authorised network participants. VERITAS is an internal accounting mechanism only. It is not offered to the public, not sold to any Opus user or external third party, not listed on any cryptocurrency exchange, and does not represent a financial investment by any person outside the Trinity DAO group.
• Not a financial product: VERITAS does not constitute a financial product, security, managed investment scheme interest, derivative, or any other regulated financial instrument under the Corporations Act 2001 (Cth), because: (a) it is not offered to the public; (b) no external party acquires rights of a financial nature through VERITAS; and (c) VERITAS has no market price, no exchange liquidity, and no speculative investment value accessible to persons outside the Trinity DAO group.
• Opus user obligations: Opus users: (a) do not acquire, hold, or trade VERITAS in connection with their use of Veritas DMS; (b) pay for all Veritas DMS services exclusively in Australian Dollars (AUD) through the Opus billing system (Stripe); and (c) have no exposure to VERITAS token value, network economics, or chain operations.
• Future changes — three-gate requirement: Trinity DAO Pty Ltd may, in its absolute discretion, modify the Veritas Network to permit external token distribution or a public network architecture. Any such change requires all three of the following conditions to be satisfied before taking effect: (a) a formal resolution of the Trinity DAO Pty Ltd Board of Directors specifically authorising external token distribution; (b) written confirmation from independent Australian legal counsel that the proposed distribution structure complies with applicable law and does not constitute an unlicensed financial product; and (c) establishment of an offshore Foundation entity as the public-facing issuer of any externally distributed tokens. Until all three conditions are satisfied, VERITAS remains an internal operational unit as described in this Section 24. No change to the Veritas Network architecture will affect existing users' Veritas DMS document access rights or attested records without separate advance notice.
