Description by CHUNG CHENG CHIU (from the App Store)
AutoSignMark is a fast, private PDF editor for iPhone, iPad, and Mac. Sign documents, mark them up by hand or with text, stamp your
signature, merge files, and save — all on device, with no account required.

• Save and reuse your signature; import an image as a stamp with automatic background removal
• Eraser to remove annotations
• Markup Presets: save a markup layout once and apply it to similar documents

• Save (overwrite) or Save As (export a clean, password-free copy)
• Export pages as JPG images
• Quick Passwords: store frequently used passwords and auto-try them on encrypted PDFs

PRIVATE BY DESIGN
AutoSignMark does not collect, track, or sell any data. Your files, signatures, and settings stay on your device. There is no
analytics, no advertising, and no third-party SDKs. The app connects to the internet only when you explicitly download a PDF.
