Protect a document, or take things out of it
Add a password, restrict printing and copying, redact what should not be seen, and strip hidden metadata. The work happens on your device, so a sensitive file never travels.

Why Flourish
Private by architecture, not by promise
Most PDF apps quietly send your file to a server to run OCR, conversion, or AI. Flourish PDF has no document upload endpoint at all — which makes it a genuine fit for legal, medical, financial and other sensitive documents.
No upload endpoint
The service has no route that accepts a document. Your file cannot be sent to us because there is nowhere to send it.
OCR and scanning on the device
Apple Vision, Google ML Kit and Windows' own recognizer read the page on your hardware.
AI on the device
Summaries and questions run on Apple Intelligence or Google's on-device models — no credits, no cloud fallback.
Only an account and a plan on our side
Your email, a user id, and which plan is active. Never a PDF, its text, or what you asked about it.
