PrivacyScrubber — Zero-Trust AI Data Masking

100% local, zero-trust PII redaction for generative AI. Mask sensitive data locally with offline OCR and batch support.

🛡️ Before you paste anything into ChatGPT, Claude, or Gemini — read this. Every prompt you send to an AI model is stored, analyzed, and potentially used for training. That means client names, patient records, financial data, and source code are leaving your device every time you use AI. PrivacyScrubber stops that. It runs entirely inside your browser — no servers, no APIs, no cloud — and replaces sensitive data with safe placeholder tokens before your text reaches the AI. When the AI responds, you restore real data locally with one click. Your data never leaves your machine. Ever. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS IN 3 STEPS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Highlight your text — email, contract, patient note, log file 2. Click Protect — names, emails, phones and IDs are replaced with tokens like [NAME_1] or [EMAIL_2] 3. Paste into any AI — when it responds, click Restore to get real data back locally No training required. No IT ticket. No policy exception needed. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✨ NEW IN VERSION 1.5.2 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ → Modernized Extension Popup — A cleaner, clutter-free main tab focusing purely on pasting, protecting, and copying. → Streamlined Settings — Moved page rules, keyboard shortcuts, and file support specifications to the advanced "Engine" tab to reduce cognitive load. → Clear Inline Helpers — Replaced non-functional tooltip hover icons with clear, self-explanatory parenthetical descriptions. → Refined PII Engine (False Positive Shield) — Updated jargon stop-lists to prevent false-positive NAME detections on common business terms like "research", "database", and "forecast". → Live injectors inside ChatGPT, Claude, Gemini, Grok, Copilot, Kimi, Perplexity, DeepSeek and Qwen. → Smart Restore — Paste any AI response and all tokens are replaced with real data in one click. → 8 industry profiles now fully active: Medical, Legal, HR, Finance, Security, Engineering, BizOps, Sales — each applying specialized detection rules for your field. → Encrypted Team Sessions — Share redacted sessions with teammates using Argon2id + XChaCha20 cryptography, zero server contact. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ZERO-TRUST ARCHITECTURE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ We don't ask you to trust our privacy policy.
