What is on this site
The written text, page design, code and original graphics on this site belong to the site operator unless a page says otherwise. Facts, formulas, unit definitions and standards that the tools rely on are not owned by anyone, and the tools themselves only carry out calculations on them.
What you may do
- Use any tool for personal or commercial work. There is no licence fee and no attribution is required.
- Use the results you create, including generated files, images and documents. They are yours.
- Link to any page, and quote short extracts of our text with a link back to the page.
What you may not do
- Copy whole pages or large parts of the written guidance and republish them as your own.
- Scrape the site in bulk, or mirror it, in a way that places load on it.
- Present this site's name or design as your own.
Your own files and content
Files, text and images you open or paste into a tool are processed on your own device and are never sent to us. We therefore hold no copies, cannot review them and cannot remove them. You are responsible for having the right to use whatever you put into a tool, and for how you use what it produces.
Reporting an infringement
If you believe something published on this site infringes your copyright, send a notice through the contact page with "copyright" in the subject line. To let us act quickly, include:
- Your name and a way to reach you.
- The address of the page on this site that contains the material.
- A description of the work you say is infringed, and where the original is published.
- A statement that you believe in good faith that the use is not authorised by the owner, the owner's agent or the law.
- A statement that the information in your notice is accurate and that you are the owner or authorised to act for the owner.
We read every notice that is complete, remove or change material that is shown to infringe, and tell you what we did. If material is removed and the person responsible believes it was a mistake, they can reply with their reasons and we will review it. Notices sent in bad faith, or that misrepresent that material is infringing, may carry legal consequences for the sender.
This site has not registered a designated agent under the US Digital Millennium Copyright Act. Notices sent through the contact page are still handled as described above.
Trademarks
Product, brand and company names that appear on the site, such as the names of video sites, document formats or social networks, belong to their owners. They are used only to say what a tool works with, and do not imply that the owner endorses or is connected with this site.
