Licences

What QuillArk is built from

Everything QuillArk ships is permissively licensed. Nothing in the application or on this site carries an obligation that would follow you into your own work.

Typefaces

This website sets its headings in Literata and its text in Inter. Both are licensed under the SIL Open Font License 1.1, which permits bundling and redistribution. Both are served from this domain rather than a font CDN, so visiting this page does not tell anyone else that you did.

Literata — © The Literata Project Authors. Licence
Inter — © The Inter Project Authors. Licence

Fonts inside the application

QuillArk bundles no fonts at all. It uses the typefaces already installed on your computer, and it reads each font's own embedding permission bits before putting one into an exported PDF or ebook. A font whose licence forbids embedding is left out, and the export tells you so rather than breaking the licence quietly on your behalf.

Libraries

QuillArk is built on Electron, React and TypeScript, with SQLite compiled to WebAssembly for search, Hunspell dictionaries for spell check, and a set of format libraries for reading and writing DOCX, EPUB, ODT, PDF and Markdown.

All 135 runtime packages are MIT, ISC, Apache-2.0, BSD or similar permissive licences. There is no copyleft anywhere in the dependency tree, and the build fails if one ever appears. The complete list, with versions, ships with the application in THIRD_PARTY_LICENSES.md.

QuillArk itself

The application is free to download and use. Its source code is not currently published under an open-source licence.

Your writing is, of course, entirely yours. QuillArk claims no rights over anything you make with it, and the files it produces are open formats you can take anywhere.
