Private by design
Quick PDF runs entirely in your browser. Your PDFs are opened, edited and saved on your own device. They are never sent to a server, so nobody (us included) can see them. It even works offline once loaded.
Questions
Will others see my comments?
Yes. Comments are saved as standard PDF notes that show in Adobe Reader, Preview and browsers.
