Keeping your personal details safe when using AI for Zero-Trust Data Masker & In-Memory PII Removal Engine is more important than ever. If you use chatbots like Browsers, client-side scripts, and completely offline redaction utilities for writing or daily tasks, your prompts are saved on remote databases. Our action AI privacy guides shows how to protect your identity while using AI. The main concern is using cloud-based tools for anonymization instead of processing locally in the browser.
Pasting text into chat interfaces without local redaction creates a persistent record. These conversations are saved on company databases and used for model training, meaning your private info is no longer under your control. Mask sensitive PII in text right in your browser with reversible tokens. No cloud upload, works offline after load, and free for 15,000 characters.
Zero-Trust Configuration & Threat Model
When users perform data analysis with AI assistants, unstructured prompts can easily leak confidential information to external servers. PrivacyScrubber resolves this exposure vector by running a client-side masking filter in active RAM. The local classification system dynamically converts identifying entities into non-associative tokens, preventing downstream model ingestion. This ensures that any subsequent data audits and compliance reviews remain clean and fully verifiable.
Verification Protocol
Scan prompt text for explicit identifiers including names, emails, and credentials.
Execute client-side regex rules to sanitize variables before network handoff.
Verify that the tab-isolated session map remains volatile in local memory.
Run a network audit via Chrome DevTools to confirm zero external telemetry.
Our zero-trust engine is pre-hardened for Automation & Operations workflows, automatically identifying and tokenizing the following parameters 100% locally.

Your Private Shield
PrivacyScrubber operates entirely on your device. Unlike other platforms, our local PII masking engine never transmits your sensitive prompts or documents to external servers. All detection and restoration happens in your computer's local RAM.
No Backend Connection: Zero API calls, zero tracking, zero logs.
Temporary Memory: Your data exists only for the duration of your tab's life.
Verification Ready: Built for professionals who need to audit their security layer with removing hidden metadata.
Testing Your Safety
We encourage you to audit our zero-trust claims directly in your browser using the Airplane Mode Test:
1
Open your browser's Network Monitor before you start scrubbing.
2
Switch to Airplane Mode (physical or simulated) and protect your text.
3
Verify that no data packets ever leave your machine.
Why Risk, Audit, and Compliance Teams Flag Unmasked AI Prompts
Even though there are privacy rules like Global privacy principles favoring data minimization at the source to protect us, they don't always stop AI companies from saving what you paste into their tools. This is why understanding text anonymizer is so important — it's the first step to taking back control of your personal data. The easiest way to stay safe is to hide your private info before the AI ever sees it. Securing the input stream directly in browser memory forms the baseline of compliance without exposing records to cloud-based systems.
Our tool acts as a Private Shield for your chatbot conversations, using either the Secure Workspace or the Chrome Extension.
How to Use AI on Real Automation & Operations Data — Without Sending a Single Real Name
Our tool acts as a Private Shield for your chatbot conversations, using either the Secure Workspace or the Chrome Extension. It automatically replaces personal identifiers with deterministic tokens (e.g., [NAME_1]) offline, ensuring the AI only processes clean context. This supports the compliance model of Zero-Trust execution. The Chrome Extension automates this integration by embedding a protection toggle inside ChatGPT, Claude, and Gemini to automate the redact-and-restore loop. By executing deterministic ZTDS™ detection parsing entirely in local memory, PrivacyScrubber preserves the usefulness of Browsers, client-side scripts, and completely offline redaction utilities for production workflows without introducing external risk.
Verify this offline capability through the Airplane Mode Verification. Disconnect from the internet and run a scrub. Since all operations run locally, this matches the standard in removing hidden metadata, ensuring your personal data stays safe.

COMPLIANCE FAQ
Frequently Asked Questions
Common questions about deploying zero-trust AI for Automation & Operations Teams.
Does protecting data with PrivacyScrubber before AI processing satisfy Global privacy principles favoring data minimization at the source?
Yes. Processing pseudonymized data for a secondary purpose (AI analysis or drafting) aligns with Global privacy principles favoring data minimization at the source because no personally identifiable data is transmitted to the AI provider. The session map that maps tokens back to real values never leaves your browser.
What specific PII does PrivacyScrubber detect for action workflows?
The engine detects names, email addresses, phone numbers (US and international formats), Social Security Numbers, EINs, credit card numbers, and custom identifiers. PRO users can add custom regex rules to match action-specific patterns such as proprietary account IDs, MRNs, or internal project codes.
Can I reverse the redaction if I use PrivacyScrubber to mask action data?
Yes. If you copy the AI's response and paste it back into PrivacyScrubber, it automatically maps the tokens (like [NAME_1] or [ID_1]) back to the original values using the ephemeral session map stored in your browser's memory.
Can PrivacyScrubber be used 100% offline without network requests?
Yes. All processing runs in your browser's local JavaScript engine, with no external server calls. Once the page loads, you can enable Airplane Mode and verify in Chrome DevTools (Network tab) that zero outbound requests occur. All cryptographic operations (including client-side pseudonymization and reverse-revealing) utilize hardware-accelerated XChaCha20-Poly1305 encryption and Argon2id key derivation running entirely inside browser RAM, ensuring your action data stays 100% on your device.
How can I verify that PrivacyScrubber sends zero data to servers?
Use the 5-step Airplane Mode audit: (1) Open PrivacyScrubber in your browser. (2) Disconnect your network connection (enable Airplane Mode). (3) Paste a text sample containing names, emails, and phone numbers. (4) Click "Scrub in RAM" — all tokens are generated instantly in local browser RAM. (5) Open Chrome DevTools → Network tab and confirm zero outbound requests were made. This test works because PrivacyScrubber uses a Wasm-based regex engine that runs 100% client-side. The session token map (e.g. [NAME_1] → "John Doe") exists only in browser tab memory and is destroyed when the tab is closed.
Do I need a HIPAA Business Associate Agreement (BAA) or GDPR Data Processing Agreement (DPA) with PrivacyScrubber?
No. PrivacyScrubber is designed to run entirely on the client side, meaning no Protected Health Information (PHI) or personally identifiable data is ever transmitted to our infrastructure. Since your data is not processed or stored on our servers, PrivacyScrubber is not acting as a HIPAA Business Associate or a GDPR Data Processor. Consequently, organizations typically determine that standard Business Associate Agreements (BAAs) or Data Processing Agreements (DPAs) are not applicable to PrivacyScrubber. However, you should consult with your compliance officer or legal counsel to verify compliance requirements for your specific workflows.
Can I customize detection rules for industry-specific data formats?
Yes. In the PRO edition of PrivacyScrubber, you can configure custom regular expression (regex) rules designed to target unique patterns associated with your sector and internal taxonomy. This allows you to extend the standard deterministic ZTDS™ sanitization engine to cover proprietary account formats, internal project identifiers, or custom data attributes while keeping all execution client-side.
Is pasting sensitive data into ChatGPT safe?
Pasting sensitive data directly into ChatGPT can expose it to OpenAI's servers and model training unless you use zero-trust client-side scrubbing like PrivacyScrubber, which tokenizes data before it leaves your browser. Protect your workflows for $15/mo with PRO.
How does client-side PII redaction work?
Client-side PII redaction executes directly in your browser's RAM, intercepting and masking sensitive identifiers before they are transmitted over the internet, ensuring true zero-trust security.
How does the Secure Workspace differ from the Browser Extension?
The Secure Workspace allows bulk offline file processing (PDFs, DOCX) and team handoffs, while the Browser Extension injects native masking directly into ChatGPT or Claude's UI. Both are included in our zero-trust ecosystem.
What is the PII MCP Server used for?
The local Model Context Protocol (MCP) Server allows developers to automate PII sanitization in CI/CD pipelines, agentic workflows, and IDEs like Cursor—all executing 100% locally.
