### LockMate: Your Ultimate Screen Lock Extension for Privacy and Security

Overview:

Meet LockMate, your ultimate companion for top-notch browser privacy and security. Packed with powerful features, LockMate ensures your private browsing sessions are safe from prying eyes. Whether you're stepping away from your device or locking specific domains, LockMate has got you covered.

Key Features:

1. Enable/Disable Passcode:
   - Customizable Security: Easily toggle the passcode feature to suit your needs. Set up a unique passcode to lock and unlock your private domains, ensuring only you have access.

2. Passcode Configuration:
   - Simple Setup: Create or modify your passcode through an intuitive interface. Set a passcode that's easy to remember but tough to guess, giving you peace of mind.

3. Private Domains List:
   - Manage Your Privacy: Keep track of all privatized domains with an easy-to-view list. Quickly view, edit, or manage the domains you've locked, ensuring your sensitive browsing activities are always under control.

4. Privatize Domains via Popup:
   - Quick and Easy Locking: Lock any domain directly from the extension popup by clicking the LockMate icon and hitting the lock button. Secure your private domains in just a few clicks.

5. Right-Click Privacy Control:
   - Convenient Access: Instantly privatize the current page or domain with a simple right-click. This functionality provides immediate control over your privacy without disrupting your browsing flow.

6. Auto-Lock for Idle Browsers:
   - Enhanced Privacy Protection: If your browser is idle for 15 seconds, LockMate automatically locks all open privatized domains. This ensures your sensitive information remains secure even when you step away.

7. 🔒 Private Session (NEW)
Start an anonymous session with a single click. While active, no history, cookies, cache, or download logs will be tracked. When ending the session, LockMate prompts you to selectively clear data — such as browsing history, cache, cookies, and downloads — giving you total control without using Incognito Mode.

What's New:

- Private Session Mode: Anonymous browsing without leaving Chrome. Choose what to erase when you’re done — no need to switch to Incognito anymore.
- Private Domain History Shield: Disable history tracking for privatized domains. Once activated, any domain you've marked as private will no longer leave a trace in your browsing history, ensuring a higher level of privacy.
