PrivacyScrubber Chrome Extension: ZTDS at the Edge (v1.5.0)
Deploy Browser-Native DLP Directly Into Your Workflow
The Problem
Copying text back and forth between a redactor and an AI chatbot is tedious and prone to human error. Most users take the risk and paste raw PII just to save time. The PrivacyScrubber Chrome Extension eliminates this friction by bringing the Zero-Trust Data Sanitization engine directly to where you work.
How It Works
Install & Activate
Add the PrivacyScrubber extension to your Chrome browser from the web store.
One-Click Scrub
A small overlay appears over the 'Send' button. Click it to sanitize text before it hits the server.
Instant Reveal
Paste AI responses back into the Restore tab to reveal original names and data from session memory.
How This Feature Improved Workflows
Try Chatbot Inline Interception
Simulate real-time prompt cleaning inside ChatGPT. Type in the mock prompt area or select a preset to watch the extension hook intercept and scrub PII at the edge.
Extension Mode Comparison
PrivacyScrubber adapts to your workflow. Compare our edge-processing capacities across Free, PRO, and TEAMS deployment models.
Advanced Edge Capabilities
Unlike basic extension filters, PrivacyScrubber's v1.5.0 framework delivers advanced edge computing features designed for strict enterprise security mandates (SOC 2 / HIPAA).
Live-Streaming Detokenizer
Leverages lightweight, debounced MutationObservers (80ms grouping) to parse and detokenize incoming AI responses in real time. original values are merged back seamlessly as they stream onto your screen without UI lag.
SPA Leak Prevention Hook
Intelligently monitors page navigation and React DOM unmount events within modern chatbot wrappers (ChatGPT/Claude/Gemini). Instantly intercepts dynamically loaded prompt boxes to block accidental data leaks.
WASM-Powered Document Sanitizer
Executes complete PDF.js rendering and Tesseract.js OCR parsing inside isolated browser content script sandboxes. Drag-and-drop sensitive bank statements or patient charts directly at the edge with 100% network silence.
Argon2id + XChaCha20 Handoff
Secures collaborative workflows with zero servers. Mapped session tokens are encrypted using libsodium WebAssembly (XChaCha20-Poly1305) on the client side before generating offline sharing links.
What's New in v1.5.0
- Universal Reveal Function: Seamlessly restore tokenized data back to its original form within Gemini and ChatGPT.
- TEAMS Synchronization: Cryptographically secure session handoff via XChaCha20-Poly1305.
- Modal Interface Overhaul: Refined glassmorphism UI for improved visibility and lower cognitive load.
- Expanded Platform Support: Natively supports Grok, Kimi, Perplexity, DeepSeek, and Qwen alongside ChatGPT, Gemini, Copilot, and Claude.
Seamless In-Situ Protection
The PrivacyScrubber Chrome Extension is built on Manifest V3, ensuring maximum performance and security. By injecting our detection matrices directly into the DOM of supported AI platforms, we catch PII at the moment of creation—before the 'Submit' button is even pressed.
Traditional "Cloud" Redactors
- Requires separate tab — copy/paste workflow
- Sends raw PII to their processing servers
- Session context lost between operations
- No visibility into what data was captured
PrivacyScrubber Extension
- Lives directly inside ChatGPT, Gemini, Claude
- All processing in browser RAM — zero server calls
- Persistent session map with one-click restore
- Full audit trail: see every token + original value
Zero-Server Engine
Unlike traditional redactors that require API calls to external NLP servers, our extension executes the entire PII detection regex matrix locally in your browser's RAM. No data is ever transmitted to us or any third party.
Technical Architecture
- Content Script Isolation: Runs in an isolated context per-tab — cannot access other extensions or tabs.
- Zero Network Requests: Verified via Chrome DevTools Network Inspector — no outbound XHR/Fetch during scrubbing.
- Session Memory: Token-to-original mappings stored in browser RAM only — cleared on tab close.
- TEAMS Handoff: Session maps encrypted with XChaCha20-Poly1305 + Argon2id before any export.
B2B Case Studies: Real-World Extension Workflows
See how the browser extension performs client-side Zero-Trust Data Sanitization (ZTDS) in practice across diverse compliance-heavy scenarios.
1. Medical Intake & PHI De-identification (HIPAA)
Audience: Healthcare Informatics & Clinical Staff
A medical assistant needs to summarize a patient's chart using ChatGPT. When they paste the patient sheet into the chat, the extension immediately intercepts the text, replacing the name, date of birth, and Medical Record Number (MRN) with tokens. The LLM processes the clinical symptoms safely, and the assistant uses the Restore tab to re-insert the real patient details on their local machine, ensuring HIPAA Safe Harbor compliance.
2. Attorney-Client Privilege & NDA Safeguarding (Legal)
Audience: Corporate Attorneys & Legal Teams
Before uploading a confidential service agreement into Claude to scan for indemnification risks, a corporate lawyer relies on the extension to mask names of key signatories, specific deal amounts, and geographical coordinates. Since all redactions run inside the local DOM memory, no privileged company secrets or NDAs are leaked to the public LLM training pool.
3. Code Sanitization & Infrastructure Security (DevOps)
Audience: Software Engineers & DevOps Teams
A developer debugging a complex server error pastes logs containing IP addresses, database connection strings, and JWT tokens. The extension intercepts the paste, replacing the sensitive infrastructure tags with placeholder tokens. Claude analyzes the stack trace and provides a debug solution. The developer gets the fix without ever exposing active API credentials or database structures.
4. Blind Hiring & Bias Prevention (HR & Recruitment)
Audience: Recruitment Specialists & HR Teams
To implement an unbiased hiring workflow, an HR manager runs candidate profiles through an AI summarization model. The Chrome Extension filters out names, physical locations, and demographic references. The AI generates summaries focused strictly on professional experience and technical skills, ensuring a fair and compliant screening process.
5. Ticket Sanitization & CRM Protection (Customer Support)
Audience: Customer Success & Support Agents
Support agents resolving billing disputes frequently copy-paste customer emails containing credit card transaction IDs and email addresses into Gemini to draft standard templates. The extension scrubs the sensitive fields, allowing Gemini to write the response. Re-hydration is performed locally, instantly pasting back the real transaction IDs before sending the final email to the customer.
Feature Reliability & Audit
This enterprise feature is powered by our Local-First Sanitization Engine. Unlike legacy cloud DLP tools, PrivacyScrubber processes your PrivacyScrubber Chrome Extension: ZTDS at the Edge (v1.5.0) logic 100% within your browser's V8 sandbox. This architectural decision ensures that even the most complex detection patterns never expose raw data to an external API.
Airplane Mode
Verified feature operational integrity without network connectivity.
Frequently Asked Questions
Does the extension read my other tabs?
No. The extension only activates when it detects an AI chatbot URL (like chatgpt.com or claude.ai). It respects the principle of least privilege.
Is the extension processing data on a server?
Never. The extension uses the exact same local Regex engine as our main site. All processing happens in your browser's isolated content script.
What platforms are supported in v1.5.0?
We currently support ChatGPT, Claude, Gemini, Copilot, Perplexity, DeepSeek, Grok, Qwen, and Kimi natively with inline scrubbing.
