## Description

Hide Sensitive Information masks sensitive fields and visible text on websites so private data is less likely to appear while you browse, present, record, or share your screen.

Features:
- Masks common sensitive fields such as passwords, email addresses, phone numbers, tokens, credit card fields, and one-time codes
- Detects sensitive inputs using field types, autocomplete attributes, labels, placeholders, and other page metadata
- Supports custom CSS selectors for site-specific or global masking rules
- Re-applies masking on dynamic pages and single-page apps as content changes
- Lets you quickly toggle masking on or off from the toolbar popup
- Stores preferences locally in browser extension storage

How it works:
- The extension processes page content locally in your browser
- It does not send webpage content to external servers
- It does not use analytics, ads, or tracking

This add-on is designed for privacy-conscious browsing, demos, screen sharing, and recordings where sensitive information should stay out of view.
