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.

Use the background color of the next section, so the shape appears to cut into the section above it.

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

Create curve, tilt, triangle and wave dividers between page sections.
