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. Production pages use Google Analytics for visit statistics; see the Privacy page for details.
