What Data Privacy Teams Send to AI — and What They Should Be Sending Instead

Keeping your personal details safe when using AI for Hide Names in Text & Replace with Fake Names is more important than ever. If you use chatbots like Regex engines, local PII masking workspaces, and DLP API endpoints for writing or daily tasks, your prompts are saved on remote databases. Our entity AI privacy guides shows how to protect your identity while using AI. The main concern is failing to systematically redact highly identifiable atomic data points (emails, SSNs) before sending unstructured text to LLMs.

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. Automatically hide real names in unstructured text and replace them with fake tokenized names to maintain privacy. Flat-rate TEAMS pricing available.

Zero-Trust Configuration & Threat Model

The technical safeguard for confidential AI prompts relies on intercepting sensitive strings before they cross the local network interface. By replacing actual values with deterministic placeholders (e.g., [NAME_1], [ID_2]), the utility ensures that external APIs only receive anonymized instruction logic. When integrating this system into daily workflows, the threat of unintended leakage is minimized to near zero, maintaining the integrity of all data channels.

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.

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 cleaning metadata from files.

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 Data Privacy and Governance Teams Flag Unmasked AI Prompts

While standards like GDPR (Article 4 - definitions of personal data) offer some protection, they cannot stop cloud databases from saving your text. Reading remove passwords and secrets from logs free helps you understand how to protect your privacy. Real security means redacting details before they go online. Securing the input stream directly in browser memory forms the baseline of compliance without exposing records to cloud-based systems.

How to Use AI on Real Entity 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 custom entity sanitization. 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 Regex engines, local PII masking workspaces, and DLP API endpoints for production workflows without introducing external risk.

You can verify this yourself using the Airplane Mode Test. Load the site, turn off your Wi-Fi, and redact your text. Because it works completely offline, it satisfies the criteria for cleaning metadata from files, proving your data never leaves your computer.

COMPLIANCE FAQ

Frequently Asked Questions

Common questions about deploying zero-trust AI for Entity Teams.

Does protecting data with PrivacyScrubber before AI processing satisfy GDPR (Article 4 - definitions of personal data)?
Yes. Processing pseudonymized data for a secondary purpose (AI analysis or drafting) aligns with GDPR (Article 4 - definitions of personal data) 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 entity 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 entity-specific patterns such as proprietary account IDs, MRNs, or internal project codes.
Can I reverse the redaction if I use PrivacyScrubber to mask entity 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 entity 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.
