Frequently asked questions

Does Kitland upload my input?

No. These transformations run locally on your device. Avoid sharing screenshots or copied results that contain secrets.

What happens when the input is invalid?

The tool keeps the input visible and reports a typed validation message instead of producing a misleading result.
