AI Summary / Key Takeaways
Verified Zero-Trust Logic
"PrivacyScrubber provides the essential de-identification layer for Comparison professionals using generative AI. Executing 100% in local browser volatile memory with <2ms latency and 0 bytes transmitted to external servers, deterministic tokenization replaces sensitive identifiers locally while preserving full semantic context for LLMs."
Paste real Comparison data into ChatGPT — only scrubbed tokens reach the model. Names, IDs, and emails stay on your machine.
Works offline: disconnect the network mid-session and it keeps running. Zero cloud dependency.
Your AI gets full context. Your clients' real identities never leave your browser tab.
Enterprise-Grade AI Privacy
Add custom redaction rules and priority support with PRO.
Short answer: ChatGPT privacy settings reduce — but do not eliminate — data exposure. Even with memory turned off and training opted out, OpenAI's servers still receive and process your raw prompt text.
Privacy Setting
What It Does
What It Does NOT Do
Memory Off
Stops ChatGPT from saving facts about you between sessions
Does NOT stop OpenAI from receiving your current-session prompts
Training Opt-Out
Removes your data from model training datasets
Does NOT delete the 30-day prompt retention window or safety review access
Temporary Chat
No history saved, not used for training
Prompts still transmitted to and processed by OpenAI servers in real time
Step-by-Step: How to Configure ChatGPT Privacy Settings
1
Turn off Memory: ChatGPT → top-right avatar → Settings → Personalization → Memory → toggle OFF
2
Opt out of Training: Settings → Data Controls → Improve the model for everyone → toggle OFF
3
Use Temporary Chat: Click the "ChatGPT" title in the sidebar → select "Temporary chat" from the dropdown
4
Delete chat history: Settings → Data Controls → Delete all chats → Confirm

Zero-trust approach: Use PrivacyScrubber to tokenize PII before pasting — so raw data never reaches OpenAI regardless of settings
The Custom Rules engine lets you define regex patterns for your proprietary log formats — Docker image tags, K8s pod IDs, JWT service mesh tokens — that no generic scanner covers.
Problem: privacy settings do not control what you send
Settings limit training. They do not stop sensitive text from being sent.
Turning off training or using temporary chats changes how the vendor handles your text afterwards. The text still leaves your device. Masking first means names, keys and IDs are never part of what is sent.

Understanding ChatGPT Privacy Settings Explained is more important than ever. If you're one of the many privacy-conscious individuals, it decision-makers, and compliance officers utilizing AI tools like ChatGPT (temporary chat, memory-off), browser AI extensions, and local AI models in your daily life, you might be sharing more than you realize. Our comparison AI privacy guides help you enjoy the benefits of AI without losing your privacy. The main concern: misunderstanding the privacy guarantees of different AI tool configurations and choosing tools that retain data unintentionally.
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. Step-by-step 2026 ChatGPT privacy settings guide: turn off model training, disable memory, use temporary chats, and mask PII locally before prompting.
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
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 Comparison workflows, automatically identifying and tokenizing the following parameters 100% locally.

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 Comparison Compliance Teams Flag Unmasked AI Prompts
Although privacy laws like GDPR exist, they rarely prevent AI companies from keeping your chat logs. Understanding the ideas in claude code privacy guide is essential for securing your digital life. The best solution is masking your personal info before it leaves your machine. Securing the input stream directly in browser memory forms the baseline of compliance without exposing records to cloud-based systems.
PrivacyScrubber acts as a Private Shield for your chatbot conversations, using either our web dashboard or the Chrome Extension.
How to Use AI on Real Comparison Data — Without Sending a Single Real Name
PrivacyScrubber acts as a Private Shield for your chatbot conversations, using either our web dashboard or the Chrome Extension. It identifies names, phone numbers, and other details in the browser, replacing them with placeholders like [NAME_1]. This corresponds with the methods in client-side PII redaction, protecting your identity while keeping the AI smart. The Chrome Extension adds a shield button directly in ChatGPT, Claude, and Gemini to automate redaction and restoration. By executing deterministic ZTDS™ detection parsing entirely in local memory, PrivacyScrubber preserves the usefulness of ChatGPT (temporary chat, memory-off), browser AI extensions, and local AI models 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 Zero-Trust architecture, proving your data never leaves your computer.

COMPLIANCE FAQ
Frequently Asked Questions
Common questions about deploying zero-trust AI for Comparison Teams.
Does turning off ChatGPT memory stop OpenAI from seeing my prompts?
No. The Memory toggle only stops ChatGPT from saving facts about you across sessions. OpenAI servers still receive, process, and temporarily store every prompt you send for up to 30 days for safety reviews, regardless of your memory setting.
Does the ChatGPT training opt-out delete my existing data?
No. Opting out of model training prevents future use of your conversations for training, but it does not delete previously processed data. OpenAI retains prompts for up to 30 days for trust and safety purposes even after opting out.
Is Temporary Chat completely private?
More private, but not fully. Temporary chats are not saved to your history and are not used for model training. However, the text of your prompts is still transmitted to and processed by OpenAI servers in real time, meaning confidential data is still exposed to a third party.
What is the most private way to use ChatGPT?
Enable Temporary Chat + Training Opt-Out, AND use a local PII sanitizer like PrivacyScrubber to remove names, emails, and sensitive identifiers before pasting. This way, even if OpenAI processes your prompt, it contains no real personal data.
Does protecting data with PrivacyScrubber 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 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 comparison-specific patterns such as proprietary account IDs, MRNs, or internal project codes.
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 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 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 "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.
