🕶️ PII Redactor / Masking
Mask email addresses and custom literal terms locally in your browser with explicit rules and generate a copyable redacted text.
Current Scope
This version only handles plain text and only supports two explicit rules: Email addresses and Custom literal terms / phrases. All processing stays local in your browser and nothing is uploaded.
Phone numbers stay out of V1 because false positives against ordinary numbers, dates, and tracking IDs are too easy. A result only means the selected rule replacement ran. It does not mean anonymization, compliance, or safe disclosure.
