Welcome to 90n90s.com (Hubmaier Ltd. t/a 90n90s.com). These Terms and Conditions (“Terms”) govern your use of our website [www.90n90s.com], the services we offer, and any transactions you may conduct through our platform. By accessing or using our website, you agree to comply with and be bound by these Terms. If you do not agree with these Terms, please do not use our website or services.
These Terms constitute a legally binding agreement between you and Hubmaier Ltd. (“we”, “us”, “our”). Our company is registered under Scots law, and any disputes arising from these Terms will be subject to the exclusive jurisdiction of the courts in Scotland.
1. Services Provided
Hubmaier Ltd. operates a platform that facilitates the dissemination and implementation of the Authorship Classification Scheme, a standardized framework for identifying levels of AI and human contribution in creative works.
2. Use of the Website
By using our website, you represent that you are at least 18 years of age or have the consent of a guardian. You agree to use the Service only for lawful purposes and in a way that does not infringe on the rights of others.
3. Intellectual Property and Licensing
The Authorship Classification Scheme, including its definitions, hierarchy, and associated logos, is the intellectual property of Hubmaier Ltd. However, to encourage transparency in AI disclosure, we grant a license for its use under the following terms:
- Royalty-Free Reuse: You are permitted to copy, distribute, and display the Authorship Classification Scheme and its official logos for educational, professional, or personal use without payment of royalties.
- Mandatory Attribution: In all formal contexts (including but not limited to articles, essays, academic papers, websites, and corporate reports), you must attribute the scheme to 90n90s.com.
- Linking Requirement: In digital contexts, a direct hyperlink back to 90n90s.com must be provided alongside the attribution.
- Social Media & Short-Form Exception: In “simple contexts” where space is limited (such as a short social media post or micro-blog), the link requirement is waived provided a standard classification marker is used in square brackets (e.g., [AI Auth+], [Human Auth], etc.).
- No Modifications: While you may apply the scheme to your work, you may not modify the definitions or levels of the Scheme in a way that misrepresents the 90n90s standard.
4. Account Registration
Certain features of the site may require account registration. You agree to provide accurate, up-to-date information and are responsible for all activities under your account. You must notify us immediately if you believe your account security has been compromised.
5. Limitation of Liability
While we strive to provide a robust framework for authorship classification, Hubmaier Ltd. does not guarantee that the use of the Scheme will prevent plagiarism or satisfy specific institutional requirements. You agree that we are not liable for any damages arising from:
- Misclassification of work by users.
- Decisions made by third parties (such as employers or educators) based on the Scheme.
- Technical errors on the website.
6. User-Generated Content
If you post content to our website, you grant us a non-exclusive, worldwide, royalty-free license to use and distribute that content. You agree not to post content that is fraudulent, illegal, or infringes on the intellectual property rights of others.
7. Termination
We reserve the right to suspend or terminate your access to the website or your right to use the Scheme logos if you are found to be in breach of these Terms, specifically regarding the failure to provide proper attribution.
8. Privacy and Data Protection
Your use of our website is governed by our Privacy Policy. We process personal data in accordance with applicable UK data protection laws.

We reserve the right to modify these Terms at any time. Updated Terms will be posted on this page with a revised “Last Updated” date. Continued use of the Service or the Scheme after changes are posted constitutes your acceptance of the revised Terms.
