Terms of Service

Last updated: 4 October 2026

1. Acceptance of the Terms

You agree to these Terms of Service ("Terms") when you tick the box to accept them as you create an account, and by accessing or using Graffiti ("the Service"). The Service includes its bookmarklet, accounts-analysis features, hosted APIs and any accompanying documentation. We keep a record of which version of the Terms you accepted and when. If you do not agree to all of the Terms, you must not use the Service.

2. Description of the Service

Graffiti is a browser-based analysis tool for iXBRL accounts. It makes the tagged data in a filing visible and supports search, comparison, validation, annotation and export. Opening a local filing does not by itself upload the original file. When you choose an AI feature, Graffiti sends your question and extracted filing content through its hosted service to large language model providers such as OpenAI.

3. Data Collection & Logging

When you use a hosted or network feature, we receive and log the information needed to provide that request. This may include:

• Account details if you create an account: name, email address, organisation, a password hash, your licence and the companies and filings you save;
• Filing URLs submitted to the hosted viewer;
• AI questions and extracted filing context, including tagged data, recovered untagged figures and, where enabled, relevant narrative passages, conversation history, Review findings and Companies House data about the company, its officers and owners;
• Model responses and related usage metadata;
• Technical information (e.g., browser type, operating system, timestamps, IP address); and
• Error messages and diagnostic logs.

Browser-only viewing, validation and note-taking do not send the filing's content to the AI service. We log hosted requests to deliver core functionality, debug and monitor service health, detect abuse and improve the product. For more details on how we handle and protect your information, see our Privacy Policy.

4. User Responsibilities

You are solely responsible for any content you submit to the Service, complying with all applicable laws, and ensuring you have the right to share that content. Do not use the Service to submit sensitive personal data, proprietary information, or any material that infringes on third-party rights.

• You must not use the Service to generate, store, or share content that is unlawful, harmful, hateful, defamatory, or infringes any third-party rights.
• You must not attempt to gain unauthorised access to any part of the Service or to related systems or networks.
• You must not disrupt or interfere with the integrity or performance of the Service (including excessive automated requests or scraping that exceeds normal usage patterns).
• You must not upload or transmit any viruses, malware, or other harmful code.
• You understand that an AI response can be wrong, and you will check it against the filing or other sources before relying on or using it.

5. Licence Grant

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable licence to use the Service for personal or internal business purposes. No other rights are granted.

This licence depends on your continued compliance with these Terms. You may not:

• Copy, modify, distribute, sell or lease any part of the Service;
• Reverse engineer, decompile, disassemble or otherwise attempt to derive the Service's source code, except to the extent that applicable law prohibits this restriction;
• Bypass, remove, disable or otherwise interfere with security or technological protection measures; or
• Use the Service to build or help build a competing product or service.

6. Intellectual Property

Graffiti, including all associated trademarks, logos, and software, is and will remain the exclusive property of Secure Technology Analytics Ltd and its licensors. All rights not expressly granted in these Terms are reserved.

7. Third-Party Services

The Service relies on third-party services, including OpenAI and Companies House. On paid plans, AI may also use live web search for relevant external context. Data sent to those services is handled under their applicable terms and policies.

8. Disclaimer of Warranties

The Service is provided "as is" and "as available" without warranties of any kind, whether express, implied, or statutory, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

Graffiti can relay content generated by large language model providers. This output is machine-generated and may be inaccurate, incomplete, biased or offensive. You agree to independently evaluate and verify any information obtained through the Service before relying on it and acknowledge that you bear all risk arising from your use of, or reliance on, such output.

9. Limitation of Liability

To the maximum extent permitted by law, Secure Technology Analytics Ltd will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses, resulting from (a) your access to or use of the Service; (b) any conduct or content of any third party; or (c) unauthorized access, use, or alteration of your transmissions or content.

10. Indemnification

You agree to defend, indemnify, and hold harmless Secure Technology Analytics Ltd and its affiliates, officers, agents, and employees from and against any claims, damages, obligations, losses, liabilities, and expenses arising from your use of the Service or violation of these Terms.

11. Modifications to the Service and Terms

We reserve the right to modify or discontinue the Service at any time without notice. We may also revise these Terms from time to time and will change the "Last updated" date above when we do. If you have an account, we will ask you to accept the revised Terms the next time you visit your profile. Continuing to use the Service after changes take effect also constitutes acceptance of the revised Terms.

12. Governing Law

These Terms are governed by and construed in accordance with the laws of England and Wales, without regard to its conflict of law principles.
