PRIVACY PROOF
Your PDF never leaves your device.

Pick a PDF from this device. The page reads its name and its size and nothing else, then looks for a request of that exact size in the list.
Requests
newest firstThis list holds the calls the page makes with fetch or XMLHttpRequest after it loaded. The page, the fonts and the app code arrive before the watcher starts.
No request has been made yet. Keep working and the list fills up as the page talks to the network.
WHAT LEAVES THE DEVICE
This page
The HTML of the page, the small stylesheet it needs and the fonts it asks for.
The app code
The JavaScript bundles that run the editor and the tools.
Your document
Nothing. It is read inside this tab and it is never sent to us or to anyone else.
