About Noxis - Privacy Watch
Noxis is a browser extension that helps prevent you from accidentally sharing private personal information when using online AI chat platforms.
As you type, Noxis scans your message in real time. When sensitive data is detected, the message is blocked before it is sent, giving you full control over what is shared.
Your data stays yours.

How It Works
1. Enter your message in an AI-powered chat interface
2. Noxis analyzes the text locally on your device
3. If private data is found:
- The message is blocked
- You see exactly what was detected
- You can replace it with placeholders like [EMAIL_MASKED]
- Or send the message unchanged if you choose
Auto-Mode Available
Enable Auto-Mode to automatically mask detected data before sending, seamless protection without interrupting your workflow.

Why Noxis Matters
AI platforms store and process conversations. Once private data is sent, it may be logged, retained, or used for training.
Noxis helps prevent:
• Identity theft
• Client data leaks
• Compliance violations
• Accidental API key exposure
• Costly professional mistakes
• Loss of privacy control
It acts as a safety net that catches errors before they become permanent.
