What happens when I change the input?
An edited input needs a new result. Run the action again; previous download links are removed so you cannot mistake an old output for the current one.
Are my files uploaded?
Your files and pasted content are processed in temporary browser memory and are not uploaded for processing. App preferences store only tool IDs, language and theme. There are no accounts, ads or automatic error reports. Closing the page discards your workspace; download results you want to keep.
