Terms of use

Last updated 10 September 2026.

Using the site

Tools Suite is provided free of charge for learning and teaching. You may use it, link to it, and refer to it in your own work. You do not need permission to send a link to a class.

What is not permitted

The software, its source, its visual design and its written content are all rights reserved. Without written permission you may not copy, redistribute, rehost, mirror, sublicense or sell this site or any part of it, nor create derivative works from it, nor extract its content in bulk by automated means.

Framing or embedding the site in another page is not permitted at present. An embed mode with an approved-origin list is planned; until it exists, please link rather than frame.

No warranty

The site is provided as it is, without warranty of any kind. The visualisations are teaching aids. They are checked against reference implementations, but they are not a substitute for your own reasoning, and they must not be relied on where a mistake would matter.

Where a tool shows illustrative data rather than real computation, it says so in the interface. Do not treat illustrative figures as measurements.

Changes

These terms may change. The date above records the last revision. Continued use after a change means the revised terms apply.
