About this extension
Cred Mail is a privacy-first phishing detector that runs entirely in your browser. It helps you spot suspicious emails and dangerous links without getting in your way.

Key Features:
* Smart Inbox Scanning: Detects urgency language, typosquatting (fake brands), and impersonation in your Gmail inbox.
* Advanced Link Analysis: Spots hidden redirect chains, homoglyph attacks (fake characters), and deceptive "login" links before you click.
* Protector Mode: Monitors websites opened via email links and warns you if they attempt to collect your password (credential harvesting).
* Local-Only Privacy: All analysis happens on your device. Your emails and data are never sent to the cloud.

Privacy Note:
This extension creates a local log of detected incidents on your device for your review. No data is transmitted to external servers.
