Is KivTools for macOS and Windows free to use?

Yes. Every tool on KivTools is free, needs no account and has no usage quota. There is no paid tier hiding behind the workbench, and no email address is required to use the result.

Where is my data processed?

Nothing is sent anywhere. This page is a static reference: the values are part of the document, and no request carries your input to a server.

What can I feed into KivTools for macOS and Windows?

The workbench takes a mix of typed values and options and returns a text result you can copy. Large inputs are usually handled without trouble, but extremely large ones are better processed in a local command-line tool.

How accurate is the result?

Deterministic output is the point: the same input should give the same result on any machine. Compare a small known-good sample first when the output feeds an automated pipeline.

Can I use the output commercially?

The output is yours: no watermark, no licence tag, no attribution requirement. Check the underlying format or library licence when the result ships in a product.

Does it work on mobile and offline?

The page works in any modern mobile browser, and the layout collapses to a single column on small screens. Local tools keep working offline once the page has loaded.
