BEFORE YOU OPEN A FILE
A few clear answers.
Are my documents uploaded?
No. PDFs, page images, and recognized text are processed in your browser and are never uploaded. Your browser downloads the app’s own files from this site, and that is all it fetches. The only things ever sent are feedback you choose to write and anonymous usage counts (for example “a PDF finished reading, 12 pages”), which never include file names, text, or images. There are no accounts or cookies.
What does my browser remember?
Your review progress and page-reading results, stored only in this browser so a closed tab can pick up where it left off. Use Forget saved work on this device on the tool’s start screen to remove them. Files you download are yours and are not affected. This is not a secure-erasure guarantee.
Can I trust every suggested split?
No. Review the boundaries and details before exporting. This is a document-organizing aid, not a guarantee of correct interpretation or a replacement for checking important correspondence.
Does this scan physical paper?
Use your scanner to create a PDF first, then open that PDF here. Letter Splitter handles the organizing step afterward.
