# Third-party notices
This project does not embed Altium software, an Altium SDK, proprietary symbol libraries or proprietary fonts. It is an independent native-format subset implementation. The initial schematic parser/model modules originated in the user's local `work/altium-render` project; the source checkout was left unchanged.
Runtime packages are installed with upstream package metadata/license files: FastAPI (MIT), Uvicorn (BSD), python-multipart (Apache-2.0), olefile (BSD), SQLAlchemy (MIT), psycopg (LGPL with linking exceptions; see distribution terms), boto3/botocore (Apache-2.0), Pillow (HPND and bundled-component licenses), and their transitive dependencies. `backend/requirements.lock` pins runtime distributions; `requirements-dev.txt` adds test/validation tools. CairoSVG is LGPL; NumPy is BSD. Consult installed distribution licenses for precise terms.
Format research is linked from `docs/COMPATIBILITY.md`. No GPL KiCad importer code is incorporated. The checksum-pinned KiCad QA fixture is downloaded to an ignored directory and excluded from Docker/source distribution; consult upstream repository and fixture licensing before redistributing it. The user's local designs are not included in project source or the image.
Administrator-supplied fonts must have appropriate web-serving licenses. Embedded document images and symbols retain their owners' rights; uploading does not grant redistribution rights.
The native PCB binary/geometry/parser modules also originate from that independently written local checkout and are adapted to this service. Format layouts were rechecked against the [KiCad developer format reference](https://dev-docs.kicad.org/en/import-formats/altium/index.html). No KiCad GPL importer implementation or proprietary PCB sample is incorporated. See [PCB provenance and compatibility](docs/PCB.md).
