Legal · Acceptable Use

Acceptable use policy.

This document is a statement of the office's posture and is intended to be read by counsel where relevant. Nothing on this page constitutes legal advice.

1 · Scope

This policy applies to all users of the service operated at orphograph.com, including the public website, the receipt pages, the verifier endpoints, the application programming interface, the Model Context Protocol server, and any other interface through which the office offers the service. By accessing any such interface, the user accepts this policy and the Terms of Service incorporated by reference.

2 · Permitted use

The following uses are permitted and are the intended uses of the service:

• The anchoring of cryptographic fingerprints of files that the user lawfully holds or is otherwise authorised to anchor.
• The verification of receipts issued by the office, whether for material the user holds or for material a counterparty has presented.
• The integration of the service into other software by way of the public application programming interface or the Model Context Protocol server, subject to the rate limits and authentication terms in force.
• The evaluation of the service in good faith, including the anchoring of test material, the inspection of receipts, and the reading of public documentation.
• Editorial, comparative, and academic reference to the service consistent with the Trademark Notice.

3 · Prohibited use

The following uses are prohibited. The list is illustrative and is not exhaustive.

• The anchoring of material the user has no right to anchor, including material the disclosure or possession of which would itself be unlawful in the user's jurisdiction.
• The submission of malicious payloads, including content crafted to exploit, degrade, or destabilise the service or any component of the surrounding infrastructure.
• Attempts to reverse-engineer subscriber identifiers, including attempts to correlate receipts to natural persons by inference, side-channel analysis, or aggregation across receipts.
• Attempts to circumvent the rate limiter by rotation of network addresses, manipulation of client-side state, or any other technical means.
• Automated scraping, crawling, or polling that materially impacts the availability or responsiveness of the service for other subscribers.
• Impersonation of the office, including the use of the wordmark, the seal device, or any associated identifier to assert authority the user does not possess.
• Use of the service to facilitate criminal activity in the user's jurisdiction or in any jurisdiction whose law is applicable to the user.
• Use of the service in a manner that violates applicable export-control law, sanctions law, or any analogous regulatory regime.

4 · Rate limits and abuse

The service is subject to rate limits as published in the Terms of Service and as adjusted by the office from time to time. The office reserves the right to throttle, suspend, or terminate any account, session, or network address that exhibits abusive patterns, including patterns consistent with the prohibited uses enumerated above. Determinations under this section are made by the office in its reasonable discretion, with reference to the apparent severity of the conduct and the harm to other subscribers and to the service.

5 · Reporting abuse

Reports of abuse should be addressed to [email protected]. A report should identify, to the extent the reporter is able, the conduct complained of, the receipt identifier or network address associated with the conduct, the date and time of the conduct, and the reporter's contact information. The office endeavours to acknowledge reports within a reasonable period and to act on substantiated reports expeditiously.

6 · Consequences of violation

The office's response to a violation is graduated and proportionate to the severity of the conduct. The available responses include, in increasing order of severity, written warning, throttling of access, suspension of the account, and termination of the account. The office may select any response, or any combination of responses, that is reasonable in the circumstances. In cases of egregious or repeated violation, the office may proceed directly to termination without prior warning.

A subscriber whose account is terminated for material breach of this policy is not entitled to a refund of fees paid for the affected billing period, nor to a refund of any unconsumed credits, except where refund is required by applicable law. Termination does not relieve the subscriber of any obligation accrued prior to termination.

7 · Reservation of rights

The office reserves the right to revise this policy from time to time. Revisions take effect not less than thirty (30) days after public posting at this address, except where an earlier effective date is required by law or by an urgent operational concern. Continued use of the service after the effective date of a revision constitutes acceptance of the revised policy. Prior versions are retained for reference where the office deems retention appropriate.
