# Third-party licences

Wymark is built on open-source software: the editors, the web framework, the desktop shell and several hundred smaller packages. Their licences ask that their copyright notices travel with the app, so they do.

**Help > Third-Party Licences** opens the full list as a draft in Wymark, unsaved until you choose where to keep it. It names every package that ships inside the app, its version, its licence and its copyright lines, with each licence text printed in full.

Two programs ship alongside Wymark and run only when you export: **Pandoc**, under the GNU General Public License, version 2 or later, and **Typst**, under the Apache License 2.0. Both are listed in the same file with their licences. The fonts of the drawing editor have their own notice, `excalidraw-fonts.txt`, in the same folder inside the app.
