## What is Mask My File?

Share safely without losing the context people actually need. Mask My File finds private details before you send a file, permanently hides only what you choose, then reopens and verifies the new copy before showing Private Ready.

WHAT YOU CAN DO
• Images and PDFs: full-width preview, up to 5× zoom, fluid drag, and precise manual selections.
• Visual files: permanent solid redaction or removal only. Face and barcode detection simply mark regions for your review.
• Text, JSON, XML, HTML, CSV, TSV, and RTF: search every match, then apply a full mask, a partial mask, a placeholder, a pseudonym, or removal.
• Remove metadata where the format supports it. Work page by page in PDFs, or protect up to 100 files at once with individual previews, cross-file search, and per-file manual selections.
• Stay organized with Private Session, project workspaces, and Placeholder Vault.

USE IT WHEN IT MATTERS
Before you send a rental application, a medical record, a pay stub with a Social Security number, or a customer file to a coworker, keep the useful context while permanently hiding the details they do not need.

PRIVATE BY DESIGN
Everything is processed on your device. There is no account, advertising, tracking, analytics, or content upload. Apple Vision and the embedded Tesseract OCR engine run locally. Face detection creates regions only: it does not identify a person, build a template, share face data, or retain it. Apple handles purchases with StoreKit. Mask My File does not use a VPN, NetworkExtension, proxy, tunnel, DNS filter, or network routing. Originals are never overwritten; temporary workspace files, Private Session data, and projects stay on the device until you delete them.

BUY ONCE. USE IT FOR LIFE.
One purchase unlocks unlimited verified outputs and batch processing for good. No subscriptions. Restore your purchase anytime through the App Store.
