What you can do
Under CC BY-NC 4.0, you are free to:
- Use FresnelPath and its outputs for any non-commercial purpose — internal engineering, academic research, community network planning, personal projects, open-source development.
- Share the tool, screenshots, reports, and analysis outputs with attribution.
- Adapt the code — fork it, extend it, build on it — for non-commercial purposes, provided you credit the original and do not restrict others' access under a more restrictive license.
"Non-commercial" means you are not using the tool primarily to generate revenue. Internal engineering analysis at a private company is generally commercial use. Academic or NGO use is generally non-commercial. If you are unsure, ask.
