Mask My File addresses a specific, practical need: redacting obvious personal identifiers (phone numbers, emails, ID numbers, addresses) from documents before sharing. Best for occasional sensitive document sharing.
Who it's for: Anyone sharing invoices, contracts, forms or identity documents who wants to strip obvious personal data before sending. HR, small business, personal finance.
Who should skip it: Legal teams requiring court-admissible redaction; that context requires specialised tools with audit trails.
No. Mask My File processes all detection and masking entirely on your device. Document content never leaves your iPhone.
Mask My File detects phone numbers, email addresses, ID/passport numbers and home addresses in common formats. It may miss unusual formatting or non-Western patterns.
Mask My File works with text-based PDFs. Scanned image-only PDFs require OCR first. Detection accuracy in scanned documents depends on OCR quality.
No. Mask My File is a convenience tool for everyday document sharing. For legal proceedings requiring certified redaction, use purpose-built legal document software.
