Third party notices

The open source the plug-ins and this site are built on, and its licences.

Last updated 27 August 2026.

These plug-ins stand on other people's work. Their licences are reproduced here because most of them ask for exactly that, and because it is the decent thing to do.

In the plug-ins

On this site

Archivo

By Omnibus Type, licensed under the SIL Open Font Licence 1.1. The font files are served from this domain rather than from a font host, so loading a page here does not tell anybody else that you did.

The server

Node.js, Express, better-sqlite3, nodemailer, multer and cookie-parser, each under its own permissive licence (MIT, or BSD in the case of better-sqlite3's SQLite core, which is public domain). No part of this site's own code is derived from a copyleft work.

What is deliberately not here

The JUCE framework is not used in any published build, so it is not listed above. If a future build uses it, this page changes and so does the licensing position: JUCE 9 is offered under the AGPLv3 or a commercial licence, and the AGPL would require the plug-in's own source to be made available to anyone given a binary. A closed source plug-in built on JUCE needs the commercial licence.
