These terms apply to your use of datamodellib, including its website, interactive labs, public API, agent skills and AI mentor (together, "the site"). By using the site, you agree to them. If you don't agree, please don't use the site.
What the site is
datamodellib is a free educational resource that summarises mental models from mathematics, statistics, economics and the social sciences. It is offered for learning and general information.
Not professional advice
Nothing on the site is financial, investment, legal, medical, public health or other professional advice. Models are simplifications: they leave things out on purpose, and their results depend on assumptions that may not hold in your situation. Before relying on a model for a decision with real consequences, check it against your own data and, where appropriate, get advice from a qualified professional.
Content and licences
- Our content. The site's original text and source code are released under the MIT licence. You may copy, adapt and redistribute them, including commercially, provided you keep the copyright and licence notice.
- Third-party material. Sources, papers, datasets and tools linked from the site belong to their respective owners and are subject to their own licences.
- The book. The library is inspired by Scott E. Page's The Model Thinker. All summaries are original syntheses; no text or figures from the book are reproduced. datamodellib is not affiliated with or endorsed by the author or the publisher, and their names are used only to identify the work being discussed.
Acceptable use
When using the site, the API or the mentor, you agree not to:
- break the law or infringe anyone else's rights;
- overload, disrupt or probe the site, or try to get around rate limits or security measures;
- scrape the site in a way that degrades it for others, when the free API and Markdown versions are available for exactly this purpose;
- use the mentor to produce unlawful, harmful or deceptive content, or to try to extract its instructions or misuse its tools;
- present the site's content or the mentor's answers as official statements from us or from the authors we cite.
We may block traffic that breaks these rules.
The public API
The API is free and read-only, offered as is. We may change, rate-limit or withdraw endpoints at any time, although we will try to avoid breaking changes. Please cache responses where you can and identify your application in the User-Agent header.
The AI mentor
The mentor's answers are generated by third-party AI models and may be inaccurate, incomplete or out of date, even when they cite sources. Check important claims yourself. Your messages are processed as described in the privacy policy. The mentor may be unavailable, limited or changed at any time.
Links to other sites
The site links to websites we don't control, including learning resources and featured sites such as CreditBase. We are not responsible for their content, availability or practices, and a link is not an endorsement of everything on that site.
No warranty
The site is provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of accuracy, fitness for a particular purpose and non-infringement. We don't guarantee that the site will be uninterrupted or error-free.
Limitation of liability
To the fullest extent permitted by law, datamodellib and its contributors are not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, data or goodwill, arising from your use of the site or your reliance on its content. Nothing in these terms limits liability that cannot be limited by law.
Changes
We may update these terms from time to time. The date at the top shows when they last changed. If you keep using the site after a change, the updated terms apply.
