## What is PDF Scanner?

CHECK THE PACKET BEFORE YOU SEND IT

Scan pages or import a multipage PDF. PageMuster builds a short review queue for possible
printed-number gaps, duplicate or near-duplicate pages, blur, and mostly blank scans.

FIX ONLY WHAT NEEDS YOU

Review the flagged pages, rescan, insert, remove, or reorder with explicit controls, then export an
ordinary PDF. Your original file stays unchanged.

TRUTHFUL WHEN A CHECK ISN'T POSSIBLE

Possible missing-page detection requires a credible sequence of visible printed page numbers. If
there is not enough evidence, PageMuster says that check is unavailable. It never claims to
certify completeness.

PRIVATE BY DESIGN

Document rendering, OCR, and supported checks run on your device. There is no account, document
server, advertising SDK, or automatic analytics upload.

OPTIONAL ADVANCED TOOLS

Some continued and advanced use requires an optional in-app purchase. Advanced tools include
larger-document checks up to 500 pages per check, private local history,
receiver-verification packages, and reusable Packet Blueprints.

REPEAT-PACKET BLUEPRINTS

Users with the optional advanced purchase can explicitly save a checked 2–50 page packet with no
unresolved review cards as a reusable Packet Blueprint. Compare a later packet with that reference
to flag possible missing, unexpected, reordered, or duplicated pages—or return an unable-to-match
result—for human review.

Blueprints use local app storage for the name you choose, the saved date, local record metadata,
page order, and compact structural signatures. They do not store the source PDF, page images, OCR
text, or imported filename. PageMuster does not transmit this data. It may be included in a
user-controlled iOS or Apple device backup, depending on system backup settings.

RECEIVER VERIFICATION

An optional advanced tool can create a self-contained PageMuster package. A recipient can import
it into PageMuster and verify transfer integrity. This verifies that the embedded PDF matches the sender's
package; it does not certify the document's meaning or completeness.
