About ChatGPT Privacy Shield
ChatGPT Privacy Shield - Protect Your Privacy While Using AI
STOP DATA LEAKS BEFORE THEY HAPPEN. Automatically redact sensitive data from your prompts before they ever reach ChatGPT.
AI chatbots are powerful, but they store what you type. Don't let an accidental paste compromise your identity, your clients, or your company.
WHY INSTALL PRIVACY SHIELD? You might trust AI, but you shouldn't trust it with your secrets. Once you hit "Enter," that data is out of your control. We provide a safety layer that sits between your keyboard and the chat, ensuring no sensitive data leaves your browser unmasked.
KEY FEATURES
• Real-Time Detection: Scans as you type. No lag.
• Smart Redaction: Replaces data with context-aware placeholders (e.g., replacing "john@doe.com" with "[EMAIL]"). This keeps the AI's response accurate while keeping your data safe.
• 100% Local Processing: Your data never leaves your device. We do not have servers. We do not collect logs.
• Full Control: Choose to alert, redact, or unmask data instantly.
WHAT WE PROTECT
We automatically detect and mask a comprehensive list of Personally Identifiable Information (PII):
• Contact Info: Names, Emails, Phone Numbers, Physical Addresses.
• ID Numbers: SSNs, National IDs, Passports, Driver's Licenses.
• Financial: Credit Cards, Bank Accounts, Crypto Wallets.
• Technical: API Keys, Auth Tokens.
• Medical: Health records and PHI.
HOW IT WORKS
1. Install the extension.
2. Type in ChatGPT as normal.
3. We instantly mask sensitive info before the request is sent.
WHO IS THIS FOR?
Essential for Lawyers, Developers, Medical Professionals, Researchers, and anyone who wants to use AI without sacrificing privacy.
