Questions
Are my PDFs uploaded?
No. PDF Desk opens and writes the file with JavaScript inside your browser tab. Nothing is sent to a server, so it is safe for contracts, IDs and bank statements.
Can someone remove the watermark?
The text is part of every page, but a determined person with a PDF editor can delete it. For IDs, a watermark like 'Only for X bank, 2026' still limits reuse.
