Local PII Masking — Redact Sensitive Data Locally

🔒 Your documents never leave your computer. 100% private. 100% offline.

What it does

Local PII Masking automatically finds and removes sensitive personal information from your
documents — all without sending anything to the cloud.

Upload a PDF, Word document, or text file, and the extension instantly detects:

• Names, addresses, phone numbers, emails
• ID numbers — NRIC/FIN (Singapore), MyKad (Malaysia), Aadhaar (India), HKID, and 60+ other
sian ID formats
• Credit card numbers (Luhn-validated)
• Organizations and locations — detected using AI in both English and Chinese

Choose how to mask it — black redaction boxes, tokenization, or partial masking — and downl
oad the clean document instantly.

DOCX files keep all formatting — tables, images, bold/italic text remain intact; only the s
ensitive data gets replaced.
