Direct Technical Standard (Zero-Trust Rule)
Redacting civil and criminal court pleadings for AI drafting requires masking individual party names, SSNs, financial account numbers, dates of birth, and home addresses, while keeping legal causes of action (e.g. Breach of Contract, Fraud), jurisdictional grounds (e.g. 28 U.S.C. § 1332), prayers for relief, and procedural dates in cleartext. Local offline detokenization ensures 100% compliance with court filing privacy rules and prevents contempt of court sanctions.

Ethical compliance around Court Document Protection for AI Analysis requires strict oversight of all AI inputs. Sharing data with ChatGPT, Claude, Copilot, and AI legal research platforms can inadvertently compromise privilege if unstructured PII is exposed. Our legal AI privacy guides provides legal teams with a blueprint for protecting client files and eliminating exposing client communications, case strategy, and witness identities to AI training pipelines, which could constitute a privilege waiver and bar discipline violation.
Pasting litigation text into third-party AI interfaces without prior sanitization risks waiving attorney-client privilege. API agreements and incognito settings do not satisfy standard discovery and safety expectations. For attorneys, paralegals, and legal operations professionals, the risk begins the moment raw text is uploaded. Protect court documents and pleadings before using AI for legal research. PrivacyScrubber sanitizes legal cases locally in browser RAM with zero cloud uploads.
Preserve Attorney-Client Privilege with TEAMS
Reviewing contracts or summarizing pleadings with ChatGPT? Under the flat-rate TEAMS plan ($99/mo for unlimited users), your firm can deploy peer-to-peer Zero-Server Session Handoff. Encrypted locally with the ZTDS™ cryptographic engine (Argon2id + XChaCha20-Poly1305), you can share session maps via secure magic links so partners and paralegals can safely reveal original client names inside their own browser RAM.
Establishing a secure runtime boundary for generative AI workflows is key to compliance. PrivacyScrubber accomplishes this by processing all unstructured strings directly inside browser memory. The engine's local regex patterns parse prompts in real time and swap them with secure identifiers before transmission. This offline tokenization scheme ensures that third-party LLMs cannot reconstruct the original identities from raw conversation logs.
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.

How to Use AI on Real Legal and Confidential Data — Without Sending a Single Real Name
Through Zero-Trust Data Sanitization, PrivacyScrubber secures legal inputs offline via our web clipboard and Chrome Extension. It tokenizes personal and litigation metadata (such as [CLIENT_NAME]) in local memory, keeping raw data off third-party servers. This aligns with enterprise data governance. The Chrome Extension adds a secure toggle in ChatGPT, Claude, and Gemini to automate the redact-and-reveal loop in-place. By executing deterministic ZTDS™ detection parsing entirely in local memory, PrivacyScrubber preserves the usefulness of ChatGPT, Claude, Copilot, and AI legal research platforms for production workflows without introducing external risk.
We demonstrate this ZTDS™ architecture with the Airplane Mode Standard. Turn off your internet connection and sanitize your documents to confirm that no packets leave your device. This satisfies the safety rules in cross-border discovery compliance for corporate data protection.
Why Legal Counsel and Risk Management Teams Flag Unmasked AI Prompts
Lawyers must maintain strict control over client secrets: attorney-client privilege (Model Rule 1.6), court confidentiality rules, and state bar ethics opinions on third-party AI use. Yet, utilizing external AI features is necessary to handle litigation volumes. Implementing the protocols in secure ai contract review helps legal teams build a secure, compliant workflow that satisfies bar requirements. Verifiable security means stripping identifiers offline. Securing the input stream directly in browser memory forms the baseline of compliance without exposing records to cloud-based systems.

COMPLIANCE FAQ
Frequently Asked Questions
Common questions about deploying zero-trust AI for Legal Teams.
Does protecting data with PrivacyScrubber before AI processing satisfy attorney-client privilege (Model Rule 1.6)?
Yes. Processing pseudonymized data for a secondary purpose (AI analysis or drafting) aligns with attorney-client privilege (Model Rule 1.6) 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 legal 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 legal-specific patterns such as proprietary account IDs, MRNs, or internal project codes.
Can I reverse the redaction if I use PrivacyScrubber to mask legal 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 legal 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 it safe for lawyers to use ChatGPT for contract review?
Uploading unredacted contracts can waive attorney-client privilege. Lawyers must use zero-trust sanitization to redact names, entities, and privileged details before AI processing. Protect your firm with TEAMS for $99/mo.
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.
