# Existing licenses and third-party material

The root `LICENSE` describes the website code grant. The following material
is excluded from that MIT grant and from any claim of exclusive ownership.
The website sharing policy grants only rights held by Bruno Ursino; it does
not replace these terms, including for material visible in screenshots.

## Parseh exports

`assets/exercise-demo.html`, `examples/english-basics/deck.html` and
`examples/maths-and-chemistry/deck.html` contain embedded Parseh CSS and
JavaScript explicitly marked `GPL-3.0-or-later`. These code components remain
under those terms; see [GNU GPL version 3](LICENSES/GPL-3.0.txt).
Do not treat these mixed-content exports as wholly MIT-licensed or wholly
proprietary. Separately authored exercise text and third-party assets retain
their own terms.

The application source is [Parseh](https://github.com/parseh-io/Parseh).
The export scripts and their input exercises are in `examples/sources/`;
README.md describes regeneration. This upstream link identifies provenance,
not a substitute for any corresponding-source obligations when distributing
GPL-covered code.
