About PII Prompt Shield

PII Prompt Shield helps prevent accidental data leaks when using AI assistants. It scans prompt text before submission and flags likely sensitive information so you can review, redact, or stop the send action. Key features: - Detects personal data patterns in English and German. - Covers names, age, email, phone, addresses, date of birth, SSN, German Steuer-ID, German IBAN, credit cards, and API keys. - Supports two protection modes: Block + Review, or Warn Only. - Selective prompt redaction before sending. - Trusted-site allowlist for domains you choose. - Works on supported AI chat sites. - Local/on-device detection logic (no external analysis service). Important note: Detection is heuristic and intended as a safety layer, not legal/compliance certification.
