# Third-party notices Font Tools uses React, add·ideas Toolbox Contract and Shell React 0.3.0 (Apache-2.0), Toolbox Helpers 0.2.0 (GPL-3.0-or-later), opentype.js and the MIT-licensed Fontkit browser build for WOFF2 inspection. Fontkit's local Brotli decoder and transitive runtime licences are recorded by the generated inventory in `LICENSES/npm-runtime-licenses.txt`. The development-only `wawoff2` package creates project-authored WOFF2 test fixtures and is not bundled in production. No third-party font, network font or conversion service is used.
