Terms of service

Every Mechanism is a public catalog at everymechanism.com. Each page explains how something works, with a 3D model when the page has one. Reading is free and does not require an account. Pages can be added, edited, or removed at any time.

The writing and the models explain a mechanism in ordinary language. They are not a repair manual, an engineering specification, a safety procedure, or professional advice. Check the manufacturer’s instructions before you take a machine apart, work on an engine, or rely on a measurement.

A number or a motion on a page is there to explain the idea. It can be simplified, and a model can differ from one particular real object.

The text, pictures, audio, and 3D models on this site belong to Every Mechanism unless a page says otherwise. You may read them in your browser and you may link to a page.

You may quote a short passage if you link back to the page it came from. You may not copy a page or a model into another product, republish them as your own, or collect the catalog to build a competing set of pages.

Do not interfere with the site, attempt to break into the admin pages, probe for passwords, or send enough traffic that other people cannot read. Do not use the models or the writing to misrepresent Every Mechanism.

Pages load typefaces from Google Fonts. A topic page may load a video player from YouTube. Those services have their own terms, including YouTube’s terms. Every page also loads Matomo to count visits, and Matomo’s terms apply to that counter. What those services receive is described in the privacy policy.

The site is offered as it is and as it is available. A page can be incomplete, a model can fail to load in some browsers, and the site can be interrupted for maintenance or for reasons outside its control. There is no promise that a page will stay online or stay unchanged.

To the extent the law allows, Every Mechanism is not liable for loss or damage that comes from using the site, relying on an explanation, or being unable to use a page. Nothing here limits liability that the law does not allow to be limited.

These terms can be updated by publishing a new version on this page. The date at the top is the latest version. Using the site after that date means you accept the updated terms. The site does not publish a postal address or a public email address.
