What Entity Professionals Send to AI — and What They Should Be Sending Instead

Protecting your privacy for Redact IBAN & Bank Accounts in Text is key for anyone using consumer AI. Chatbots like Regex engines, local PII masking workspaces, and DLP API endpoints save everything you type into their prompt boxes. Our entity AI privacy guides helps you run AI queries safely without exposing failing to systematically redact highly identifiable atomic data points (emails, SSNs) before sending unstructured text to LLMs to public datasets.

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. Hide international bank account numbers (IBAN) and routing numbers in plain text locally. PrivacyScrubber processes all bank details securely on-device. Includes Flat-rate TEAMS pricing and Zero-server architecture.

Why Entity Compliance Teams Flag Unmasked AI Prompts

Privacy guidelines like GDPR (Article 4 - definitions of personal data) offer some protection, but the responsibility of data safety remains with the user. Checking the articles in how to remove email addresses from text automatically is the first step to securing your digital life. Real security means redacting details before they go online. Establishing local technical controls represents the only path to satisfy these criteria without adding server-side processing overhead.

PrivacyScrubber serves as an Invisible Shield for your AI inputs, working via our copy-paste web workspace or the PrivacyScrubber Chrome Extension.

How to Use AI on Real Entity Data — Without Sending a Single Real Name

PrivacyScrubber serves as an Invisible Shield for your AI inputs, working via our copy-paste web workspace or the PrivacyScrubber Chrome Extension. It scans your text in local memory to swap names and emails with secure placeholders (like [NAME_1]) before transmission. This matches the standard described in entity-level DLP, allowing you to use AI without sharing your identity. The Chrome Extension embeds a protect button directly inside ChatGPT, Claude, and Gemini to automate the entire process. Processing data through browser-based Named Entity Recognition allows safe integration of Regex engines, local PII masking workspaces, and DLP API endpoints for complex tasks while preserving client privacy.

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 cleaning metadata from files, ensuring your personal data stays safe.

Zero-Trust Configuration & Threat Model

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

  • Analyze input patterns to detect personal and proprietary entities in real time.
  • Apply local Named Entity Recognition to tokenize primary identifiers.
  • Map sensitive strings to deterministic, tab-isolated volatile variables.
  • Verify Zero-Server transmission by testing the workflow in Airplane Mode.

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 "Protect PII" — 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 Named Entity Recognition (NER) model 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.
