Documents stay on this device
PDFs, their filenames, page selections, previews and output bytes are held in memory. They are not uploaded or saved to browser document history. Clear files or leave the tool to release them.
Network requests
Local processing libraries and fonts load from this site. PDF scripts are not executed; external content is not loaded from the document. This does not mean every file is harmless: use files you trust.
Analytics
Analytics is disabled on localhost, QA and unknown hosts. The confirmed production and staging hostnames use shared Umami analytics, with reports separated by hostname. Usage analytics counts page visits and fixed operation events with a categorized source tag, never PDF content, filenames, selections or raw source URLs. The analytics provider also derives technical information such as browser, device and country from the request. Analytics settings provides an explicit opt-out; Do Not Track and storage failures close tracking.
Optional feedback
Normal feedback is sent to the production feedback service and database after verification. QA feedback is sent only to the separate test service and database. Your chosen rating, reason and message are sent together; the verification provider receives the requests needed to verify your submission. No feedback is sent to analytics. Submit only a chosen rating, reason and message, never your document or sensitive information.

Support is optional and does not unlock features. Opening the author-support dialog may load PayPal's script and make requests to PayPal. A secure PayPal link is available if the embedded view fails. Payment is handled by PayPal; no document data is shared. No real payment is required for testing.
