Privacy Policy

Last updated: January 10, 2026

Overview

ChatShield ("we", "our", or "the extension") is committed to protecting your privacy. This policy explains how our Chrome extension handles your data.

Data Collection

We do not collect any personal data.

ChatShield is designed with privacy as a core principle:

• All text scanning happens locally in your browser
• No data is transmitted to our servers or any third party
• No analytics or tracking code is included
• No cookies are set
• No user accounts are required

Data Processing

The extension processes text you type into supported AI chat tools (ChatGPT, Claude, Gemini) to detect potentially sensitive information such as:

• Email addresses
• Phone numbers
• Social Security Numbers
• Credit card numbers
• API keys and credentials

This processing occurs entirely within your browser. The text is never sent anywhere.

Local Storage

The extension stores minimal data locally using Chrome's storage API:

• Your preference settings (enabled/disabled state)
• Aggregate statistics (total items detected - no actual content)

This data stays on your device and is never transmitted.

Permissions

The extension requires the following permissions:

• activeTab: To scan text on the current page
• storage: To save your preferences locally
• Host permissions: Limited to ChatGPT, Claude, and Gemini domains only

Third Parties

We do not share any data with third parties because we do not collect any data.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date.
