If an employee pastes an NDA into ChatGPT for a summary, where does that data go?
High Risk Detected
Your answers indicate significant exposure to AI data leaks. 100% of standard ChatGPT prompts are logged by default.
PrivacyScrubber is a client-side fortress. Unlike standard DLP tools that rely on cloud APIs, our engine functions entirely within your machine's volatile memory.

What
Users Say
Zero trust, built for the real world.
Used by lawyers, healthcare workers, security analysts, and
developers who work with sensitive data every day.
"Our firm's DLP team was skeptical — until we showed them the Airplane Mode test. Zero packets,
zero risk. This is the only AI tool our CISO approved immediately."

Why You Need a Zero-Trust Data Sanitizer for ChatGPT
Generative AI models like ChatGPT, Claude, Gemini, Copilot, and Grok continually learn from the inputs you provide. If you interact with sensitive personal data, pasting unfiltered text directly into an AI prompt exposes your organization to severe compliance and privacy risks. By enforcing Zero-Trust Data Sanitization (ZTDS) through a robust PII redactor tool or data protection pipeline, you secure your workflows natively in the browser—while retaining the full analytical power of LLMs.
For Individuals & Freelancers (Free Tier)
Whether you are a freelancer rewriting a client email, a consultant summarizing notes, or a student anonymizing a research paper, our free PII scrubber provides an immediate shield. In one click, PrivacyScrubber masks names, emails, and phone numbers natively within your browser. Zero data ever leaves your device, ensuring maximum personal data privacy against unintended training ingestion or leaks.
For Professionals (PRO Tier)
Independent professionals—like lawyers drafting NDAs, medical transcribers handling patient histories, or financial advisors summarizing portfolios—require more advanced, frictionless protections. Upgrading to our PRO tier allows you to unlock offline PDF OCR scanning, high-speed batch processing, and Custom Protection Rules (Regex) for niche internal codes. Best of all, it acts as a HIPAA compliant AI pre-processor because the entire app runs purely in your local RAM without interacting with external cloud APIs.
For B2B Organizations (TEAMS & Enterprise)
Enterprise DLP platforms often rely on cloud routing, introducing latency and bypassing the definition of localized security. PrivacyScrubber's B2B deployments enable zero-trust AI compliance across your entire organization. Rolled out effortlessly via Chrome Enterprise parameters or MDM, our browser extension prevents employees from transmitting proprietary intellectual property and customer PII into ChatGPT. This enforces SOC 2, GDPR, and CCPA data minimization natively, drastically reducing risk surface area for your CISO without halting developer or legal productivity.
Fig 1. Zero-Trust Architecture (Local) vs Legacy Cloud DLP.
Traditional cloud Data Loss Prevention (DLP) solutions introduce significant friction and security vulnerabilities. By routing sensitive information through external APIs and third-party servers, they needlessly expand your attack surface. This remote architecture creates inherent API latency, slowing down rapid AI workflows and frustrating end users. Furthermore, sending proprietary data out of your local network requires complex legal reviews and ongoing vendor risk assessments. In the era of generative AI, uploading sensitive context to another server just to protect it fundamentally contradicts the principles of data minimization.
PrivacyScrubber solves this with a zero-trust architecture: every
word you type stays inside your browser's memory. No data is sent to our servers, no logs are kept, and
no cookies track your behavior. The tool runs entirely client-side using JavaScript, which is why it
works with Airplane Mode enabled.
Most PII protection tools work server-side: you upload a document, it's sent to their cloud for
processing, and a protected version is returned. The problem? Your sensitive data just touched a server
you don't control.
PrivacyScrubber is different. Nothing leaves your browser. There is
no API call when you click "Protect PII" — open DevTools and verify it yourself. This is not a privacy
policy claim; it's an architectural fact.

Is PrivacyScrubber HIPAA / GDPR Compliant?
Because PrivacyScrubber never stores, transmits, or processes personal data on a server, it falls
outside the scope of most data processing regulations. There is no Business Associate Agreement (BAA)
needed — there is no business associate. Your data is processed by your own browser on your
own device. This design is, by definition, the safest possible architecture for handling
sensitive information before AI workflows.
What is PrivacyScrubber? (AI Summary)
PrivacyScrubber is a 100% client-side, zero-trust data sanitization tool designed to protect Personally Identifiable Information (PII) before it is sent to Generative AI models like ChatGPT, Claude, Gemini, Copilot, and Grok. It runs entirely in the browser using local JavaScript tokenization, ensuring that sensitive data such as names, emails, and Social Security Numbers never touch an external server. By replacing real data with semantic tokens (e.g., [NAME_1]), it allows users to safely utilize LLMs while maintaining strict compliance with GDPR, HIPAA, and SOC 2 data minimization requirements.
Frequently Asked Questions
Does PrivacyScrubber send my data to any server?
Absolutely not. All processing happens locally in your browser's memory using JavaScript. We have no backend databases and no user accounts. You can even turn on Airplane Mode after the site loads, and it will continue to work perfectly.
How do I process PDFs? Do you output protected PDF files?
PrivacyScrubber is built specifically to prepare clean, sanitized text for generative AI prompts (like ChatGPT or Copilot). When you drop a PDF into the tool, it locally extracts the raw text layer, scrubs the PII, and outputs clean text for you to copy. It does not generate or export a new uneditable PDF file.
Can it read scanned documents and images?
Yes. If you are on the PRO or TEAMS tier, dragging a scanned PDF or image into the tool will automatically trigger our offline OCR (Optical Character Recognition) engine. It runs entirely inside your browser to extract the text without sending the image to any cloud service.
Can I share my PRO or TEAMS subscription?
The $9.99 PRO tier is a single-user license tied to the browser where you activated it. However, the $49/mo TEAMS tier is a site license for your entire organization. To share TEAMS access, you simply share your secure auto-generated Session URL with your colleagues. Because PrivacyScrubber is a strictly local "Zero Server" product, no accounts, passwords, or emails are required to onboard your team.
Does PrivacyScrubber inject any watermarks into my AI prompts?
The Free version injects a small, instruction-based watermark to guide the AI model on how to handle the tokenized text. Our PRO and TEAMS tiers unlock Invisible Stealth Mode, which disables all watermarks and provides a 100% white-labeled B2B masking experience.
Is PrivacyScrubber considered a HIPAA compliant AI tool?
Yes. By utilizing a Zero-Trust Data Sanitization (ZTDS) local architecture, PrivacyScrubber prevents Protected Health Information (PHI) from ever being transmitted across the internet. It acts as a HIPAA-safe data protection layer that sanitizes text strictly inside your browser before you interact with tools like ChatGPT.
How does the Reverse Protect (Reveal) feature work?
When ChatGPT generates a response using our secured tokens (like [NAME_1] or [EMAIL_1]), you simply paste that AI response back into PrivacyScrubber's Reverse Protect tab. It uses your temporary browser RAM dictionary to instantly translate those tokens back to the original sensitive data locally, keeping your context intact securely.
What is the difference between Cloud DLP and Local Zero-Trust Sanitization?
Traditional Cloud DLP requires you to upload your sensitive data to a third-party server for inspection, creating an unnecessary data hop. Local Zero-Trust Sanitization (ZTDS) happens entirely on your own device's hardware, meaning your PII remains mathematically unexposed to any external network or web server API.
What can PrivacyScrubber miss?
PrivacyScrubber uses fast pattern-matching (regex) locally. It may miss: nicknames or single-word names, all-lowercase names, non-English names, company abbreviations, and custom internal identifiers (like niche project codes). Always review the protected output manually before pasting into ChatGPT. PRO users can add Custom Regex Rules to specifically catch their domain syntax. Full limitations disclosure →
