AI Context Guard - Privacy Policy
Effective Date: November 25, 2025 | Last Updated: November 25, 2025
Summary: AI Context Guard processes everything locally in your browser. We don't collect, store, or transmit any of your data to external servers. Your privacy is absolute.
1. Introduction
AI Context Guard ("we," "our," or "the extension") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our Chrome extension designed to prevent accidental data leaks when using AI platforms.
2. Information We Do NOT Collect
AI Context Guard is built with a privacy-first approach. We explicitly DO NOT:
- Collect any personal information
- Track your browsing history
- Monitor the content you type or paste
- Transmit any data to external servers
- Use analytics or tracking services
- Share information with third parties
- Store actual sensitive data (secrets, credentials, PII)
- Use cookies or similar tracking technologies
3. Local Data Storage
The extension stores the following data locally on your device only using Chrome's secure storage API:
Detection Event Logs:
- Timestamps: When detection events occurred
- Detection counts: Number of items found (e.g., "3 critical, 2 high")
- Detection types: Categories detected (e.g., "AWS Key", "Email")
- Action taken: User response (redacted, cancelled, or forced)
- Page URL: Which AI platform was being used
Important: We store only metadata about detections, NEVER the actual sensitive content.
User Preferences:
- Extension settings (warnings enabled, auto-redact, logging preferences)
- Scan delay configuration
- UI preferences (popup size)
4. How Data is Processed
All text scanning and detection occurs entirely within your browser:
- Content is analyzed using client-side JavaScript regex patterns
- No network requests are made for content analysis
- Processing happens in real-time on your device
- Detected patterns are matched locally against our detection library
5. Data Retention
- Event logs: Automatically deleted after 7 days
- User preferences: Stored until you change them or uninstall
- Maximum event storage: 5,000 most recent events (older ones automatically removed)
You can manually clear all data at any time through the extension settings.
