## What is PDF Sign Pro?

Sign any PDF in seconds — without sending it to the cloud.

PDF Sign Pro is a fully offline e-signature app for iPhone and iPad. Drop in a document, draw your signature, place it exactly where you want, and export — all on your device, with a tamper-proof audit trail.

WHY PEOPLE CHOOSE IT
• Completely offline — your documents never leave your device
• Apple Pencil + finger signatures
• Tap to place your signature exactly where you want it, on any page
• Built-in audit trail: a tamper-evident, hash-chained log of every action
• Export to PDF or share via AirDrop, Mail, or Files
• No subscription, no cloud account, no tracking

PERFECT FOR
• Freelancers signing contracts on the go
• Small business owners managing NDAs and quotes
• Real estate agents handling listing agreements
• Anyone who hates uploading sensitive PDFs to a third-party service

HOW IT WORKS
1. Open any PDF
2. Tap "Sign" — draw your signature with your finger or Apple Pencil
3. Tap the page to place your signature exactly where you want it
4. Add more signatures on other pages if you need them
5. Export — every action is logged in the audit trail

AUDIT TRAIL
Every import, signature, and deletion is recorded in a tamper-evident, SHA-256 hash-chained log inside the app — so you always have a timestamped history of what happened to your documents.

PRIVACY
• No analytics, no third-party SDKs, no tracking
• No cloud upload — ever
• No account required
• All processing happens on-device
