This is a small, independently built tool. The quickest way to get something fixed is to describe exactly what you did, what you expected, and what happened instead.
Bug reports
Useful details: your browser and version, the canvas size, the preset, and whether the problem appears in the preview, the download, or both. If the exported file looks different from the preview, please say so explicitly — that is treated as a serious defect.
Reporting misuse
Graphics are created entirely in the user's browser and are never stored on our servers, so there is nothing here to take down. If a graphic made with this tool is being used to impersonate you, report it to the platform hosting it — that is the only party able to remove it.
