You may rely on a statutory permitted act under the Copyright, Designs and Patents Act 1988 (including fair dealing for the purposes of research, private study, criticism, review, or news reporting under ss.29–31) to the extent applicable. Circle Green does not grant any licence to infringe third-party intellectual property rights.

Decompilation is permitted solely to the extent required to achieve interoperability with an independently created program, in accordance with the Copyright, Designs and Patents Act 1988, s.50B. Any decompilation beyond this limited exception is a breach of this Policy and may constitute copyright infringement.

• misrepresent your identity, affiliation, authority, or relationship to Circle Green or any third party;

• use the Services to create, alter, or process documents for the purpose of deception, fraud, or misrepresentation; or

• forge, alter, or falsify any document, record, signature, or identity credential through the Services.

4. USER RESPONSIBILITY FOR UPLOADED CONTENT

You are solely responsible for all content and files you upload to the Services. By uploading any content, you warrant that:

• you own the content or hold all necessary rights, licences, and permissions to upload and process it through the Services;

• the content complies fully with this Policy, the Terms, and all applicable laws;

• the content does not violate any third-party rights, including intellectual property rights, privacy rights, or rights of personality;

• where the content contains personal data, you have a valid lawful basis for processing it and have complied with all applicable data protection obligations; and

• you are not subject to any legal obligation (contractual, regulatory, or otherwise) that would prevent or restrict your uploading or processing of the content.

Circle Green does not proactively monitor, review, or verify uploaded content prior to or during processing. This does not limit Circle Green’s right to take action upon becoming aware of content that violates this Policy, applicable law, or the Terms.

5. DOCUMENT PROCESSING RISKS

The Services process documents automatically without human review. By using the Services, you acknowledge that:

• files you upload may contain personal data, sensitive information, confidential business data, or other material requiring specific legal authority to process;

• you are solely responsible for ensuring that your use of the Services to process any such content is lawful;

• Circle Green does not validate the legality, accuracy, or integrity of uploaded content or processed outputs;

• processed outputs are provided on an ‘as is’ basis; you are responsible for verifying all outputs before relying on them; and

• Circle Green’s liability for processing errors, data corruption, or output inaccuracies is limited as set out in the Clause 12 of these Terms.

6. ENFORCEMENT

Circle Green reserves the right to investigate suspected violations of this Policy and to take enforcement action proportionate to the severity of the violation. Enforcement action will be taken in a manner consistent with our obligations under applicable law, including the Consumer Rights Act 2015 and the Digital Markets, Competition and Consumers Act 2024.

Enforcement actions are graduated according to the severity of the violation.

7. REPORTING VIOLATIONS

If you become aware of any misuse of the Services or a suspected breach of this Policy by another user, please report it to us:

Reports should include as much detail as possible, including the nature of the suspected violation, any relevant file names or identifiers, and the time and date of the observed activity. Circle Green will treat all reports in confidence and investigate them in accordance with this Policy.

8. CHANGES TO THIS POLICY

We review this Policy at a minimum on an annual basis to ensure compliance with digital safety and e-commerce regulations, and additionally whenever new legislation comes into force that materially affects its scope.

Material changes, particularly changes that expand the scope of prohibited conduct or alter enforcement consequences, will be notified to you by email (where we hold your address) at least 30 days before the changes take effect, and/or by a prominent notice on the Website.

Where you are a consumer and the changes would materially disadvantage you, you retain the right to terminate your use of the Services without penalty during this 30-day notice period.

9. GOVERNING LAW AND JURISDICTION

This Policy is governed by and construed in accordance with the laws of England and Wales. Any disputes arising under or in connection with this Policy shall be subject to the jurisdiction provisions set out in the Terms and Conditions, Section 18.

Nothing in this Policy affects any mandatory consumer protection rights you have under the laws of your country of habitual residence that cannot be excluded by contract. EU consumers retain rights under their applicable national law and EU GDPR regardless of this governing law clause.
