Frequently Asked Questions
What is PII?
PII (Personally Identifiable Information) is any data that can identify an individual — email addresses, phone numbers, government IDs, financial account numbers, and physical addresses.
Is my text uploaded for analysis?
No. All pattern detection runs locally in your browser. Your text is never transmitted to any server.
Can I add custom detection patterns?
Use our Regex Privacy Pattern Tester for custom regex rules against any text.
How is this different from the Sensitive Data Scanner?
The PII Pattern Detector provides colour-coded inline highlighting. The Sensitive Data Scanner produces a structured severity-rated report — better for document audits.
