Sensitive Data Exposure Classifier

Scan text, logs, or JSON for PII, PHI, payment data, and leaked secrets before you share it. Findings map to GDPR / PCI-DSS / HIPAA exposure and a remediation checklist. Card numbers are Luhn-validated; every match is masked. 100% offline — nothing is stored or logged.

Processed in memory only. Matches are masked in the result. Don't paste data you're not authorized to handle.
