Credits and licences

Our own code

The tools and page layouts are written for this site. The pages make no requests to other servers.

Third-party material

No third-party code, fonts or images. Some pages use published figures and name their sources on the page, for example the kids shoe size chart uses the sizes printed on two brands’ own size-chart pages, read on 17 October 2026. If we add any library, font or data set, it will be listed here with its licence and a link (data/credits.json, rendered below).
