Privacy
Last updated: May 2026
PDF PRO SAFE is designed to know NOTHING about you. This page describes, plainly, what we do (and especially what we don't do) with your data.
Your files stay on your device
Almost every tool (merge, compress, sign, OCR…) runs in your browser via WebAssembly and Web Workers: no PDF, no image, no password is ever sent to a server, and the app keeps working offline after the first load. The only exception is the two Office-conversion tools — PDF to Word and PDF to Excel — which must send your file to our server for the duration of the conversion. They are clearly marked with a banner, and the file is processed in memory and deleted immediately, never written to disk or logged.
We don't set tracking cookies
No analytics cookies, no advertising cookies, no third-party pixels. The only cookie we set is NEXT_LOCALE, a functional cookie that remembers your preferred language (FR / EN) — it's never sent to third parties and expires at session end.
Local storage for your convenience
While you use the tools, your files are temporarily kept in memory (IndexedDB) inside your browser so you can navigate between tools without re-uploading. This storage is local, never leaves your device, and is fully erasable by clearing your browser cache or via the « Clear all » button.
External connections (OCR and Office conversion)
On first use, the OCR tool downloads the Tesseract engine (~3 MB, from jsdelivr) and a language model (~10 MB, from projectnaptha); these are then cached so it works offline, and the content of your PDFs is never transmitted. The PDF to Word and PDF to Excel tools do send your file to our conversion server: it is processed in memory, returned right away, then deleted — never written to disk, never kept, never logged.
Your rights
Since we collect no personal data, there's nothing to export, rectify or delete server-side. You can erase all local traces from your browser at any time (clear cache + IndexedDB).

Does this policy feel incomplete or ambiguous? PDF PRO SAFE's source code is open — you can verify for yourself that the promises above are kept.
