COMPLIANCE FAQ
Frequently Asked Questions
Common questions about deploying zero-trust AI for Comparison Teams.
Do cloud AI models use my prompts for training?
By default, popular models like ChatGPT and Claude may retain conversation histories to improve their models. Your prompts can sometimes be reviewed by human trainers unless you specifically opt out or use an enterprise tier.
Is 'Temporary Chat' or 'Incognito Mode' completely private?
Not entirely. While your data won't be used for training, the input is still sent to their servers and kept for 30 days for safety monitoring. Zero-trust local sanitization is the only way to ensure data never leaves your device.
Why shouldn't I just build an API integration for privacy?
While API integrations typically have better data policies (e.g., zero retention for training), they require development resources and server maintenance. PrivacyScrubber works instantly client-side without any complex setup.
Does Anthropic Claude protect confidential business data?
Consumer Claude interactions may be logged according to Anthropic's policy. While they offer robust privacy for enterprise customers, redacting identifiers locally before sharing context is the safest approach for sensitive logic.
How can I verify PrivacyScrubber doesn't steal data?
Use the Airplane Mode Test: open PrivacyScrubber, turn off your internet connection, and run a redaction. Because it operates 100% in your browser's local RAM, it processes text perfectly without external requests.
What happens when the AI returns my redacted data?
PrivacyScrubber maintains a secure, temporary mapping (like [NAME_1] -> John Doe) in your browser memory. Paste the AI's response back into the tool, and it instantly reverse-matches tokens to restore original context natively.
What is the most secure privacy-focused AI tool?
The most secure approach is not trusting the AI provider's servers, but instead implementing Zero-Trust Data Sanitization locally. Tools like PrivacyScrubber redact PII (Personal Identifiable Information) in your browser's RAM before the prompt is transmitted, ensuring absolute privacy regardless of the AI model you use.
Do enterprise AI tools like ChatGPT Enterprise train on my data?
By default, OpenAI's Enterprise terms of service state they do not use customer data to train their models. However, the data is still transmitted and stored on their servers in plain text. A true privacy-focused approach requires masking sensitive data locally so that even if the server is compromised, the data remains unreadable.
Why is local browser-based PII redaction safer than Cloud DLP?
Cloud Data Loss Prevention (DLP) proxies require you to route all your traffic through a third-party server, creating a new point of failure and bottleneck. Local browser-based redaction operates entirely on your device, meaning the unencrypted sensitive data never travels over the network.
Does protecting data before AI processing satisfy GDPR?
Yes. Processing pseudonymized data for a secondary purpose (AI analysis or drafting) aligns with GDPR 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 comparison use cases?
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 comparison-specific patterns such as privacy focused ai tools.
Can I reverse the redaction if I use PrivacyScrubber to mask comparison 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 offline for privacy focused ai?
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 comparison 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 specifically for privacy focused ai tools PII safety?
Yes. In the PRO edition of PrivacyScrubber, you can configure custom regular expression (regex) rules designed to target unique patterns associated with privacy focused ai tools and other sector-specific nomenclature. 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.
