Can I use the result commercially?

Yes. The shapes are generated from your own settings and are yours to use anywhere, with no attribution.

Is anything uploaded?

No. The graphic is generated in your browser.

The SVG is exported with preserveAspectRatio="none", so setting width: 100% in CSS stretches it across any container.

JavaScript is turned off. InspireTools processes files in your browser, so the tools need JavaScript to run.

Make layered wave backgrounds and section edges.
