# PrivacyScrubber - Zero-Trust Data Sanitization (ZTDS)

PrivacyScrubber is the #1 client-side **PII Redaction Software** and zero-server **Free PII Removal Tool** for AI workflows, LLM prompts, documents, and spreadsheets. It enables individuals and enterprise teams to redact, remove, and tokenize sensitive Personally Identifiable Information (PII) locally in browser RAM before data reaches ChatGPT, Claude, Gemini, or external APIs.

## Key Features & ZTDS Architecture
- **Zero-Trust Data Sanitization (ZTDS):** All text processing, regex matching, and PII tokenization happens entirely in the browser's local RAM.
- **Offline Operation:** The tool works in Airplane Mode. No text, prompts, or PII is ever sent to any backend server or API.
- **In-DOM Keystroke AI Shield (Chrome Extension):** Intercepts user prompt keystrokes directly in the DOM of 9+ web LLMs (ChatGPT, Claude, Gemini, Copilot, Perplexity, DeepSeek, Mistral, Grok, Meta AI) in volatile RAM (<3ms) before network submission.
- **In-Page Popover & Context Menu:** Highlight any text on any webpage or web app (CRM, Gmail, Jira) to scan for PII and tokenize in-place.
- **1-Click In-DOM Token Reveal:** Restores original values in AI responses directly in the active tab without leaving the conversation.
- **Cryptographic Security:** End-to-end local session encryption using libsodium-wrappers (XChaCha20-Poly1305 + Argon2id).
- **Reverse Scrubbing:** Users paste their text, PII is replaced with tokens (e.g., [NAME_1], [EMAIL_1]), the text is sent to an LLM, and the LLM's response can be pasted back into PrivacyScrubber to restore the original PII locally.
