Privacy

No upload, no storage, no tracking of file contents. When you open a PDF with this tool, it is read and scanned entirely inside your browser. The file is never sent to a server, never written to disk by us, and never inspected by anyone but you.

This site runs no analytics and sets no cookies. No third-party script runs on any page: the Content Security Policy allows scripts from this domain and nothing else, so a browser will refuse to load anything else even if it somehow appeared. If that ever changes, it will be disclosed here — and nothing we could add would be able to read what is inside your documents, because the scan never leaves your browser in the first place.

The site does store something in your browser: a service worker keeps a copy of its own pages, scripts and the scan engine, so that it keeps working when you are offline. That cache holds this site's files and nothing else — your PDF is never in it, because your PDF is never fetched over the network in the first place. Clearing site data removes it.

There is one more case, and it is the only time anything read out of your file is written anywhere. Switching the site's language loads a different page, which would otherwise throw away a report you are in the middle of reading, so clicking that link hands the report to the next page through session storage — private to this tab, erased when the tab closes, and never sent anywhere. The page that receives it deletes it before it draws anything. It is written only by that click: scan a file and never switch languages and nothing about it is stored at all.

If you have questions about this policy, open an issue on the project's GitHub repository.
