Sensitive Data Scanner

Upload a text file — log file, CSV, report, source code — and scan it for sensitive personal data. Detects emails, phone numbers, credit card numbers, SSNs, IBANs, API keys, private keys, IP addresses, and more. Produces a severity-rated report with exact line numbers.

All processing happens locally in your browser. No data is uploaded.
