Third-Party Notices
Some interactive features on this site include open-source software, which is distributed under its own license. The notices below list what is physically distributed from this site, where it came from, and the exact license text supplied by each project.
These notices are informational and are not legal advice. Exact file sizes, SHA-256 checksums, and reproducible acquisition steps are kept in this site’s repository documentation rather than on this page.

- glulxe.jsGlulx VM is not needed for a .z3 story file.
- ie.js / waiting.gifLegacy-browser shim and loading animation; not needed and motion is avoided.
- Scare (GPL-2.0), TADS (GPL-2.0)Not present in the Inform 7 release asset and not vendored. No GPL-licensed code is physically included in this proof.
- Iosevka fonts (OFL)Not present in the Inform 7 release asset. No webfont is loaded; system fonts only.
