About this extension
TrackBlock Email Privacy helps protect your privacy by detecting and blocking tracking pixels embedded in emails.

Many marketing emails contain invisible tracking images that notify senders when an email is opened, what device was used, and sometimes approximate location information. This extension identifies common tracking patterns and prevents these requests from loading.

Features:

• Detects tracking pixels in incoming emails.
• Blocks known email tracking techniques before they load.
• Supports Gmail, Outlook, Yahoo Mail, Proton Mail, Fastmail, Zoho Mail, iCloud Mail, Tuta Mail and other major webmail providers.
• Performs all analysis locally within the browser.
• Does not collect, transmit, store, or sell user data.
• No account creation required.
• Lightweight and designed for minimal performance impact.

Privacy First:

TrackBlock Email Privacy does not send email content, metadata, browsing history, or personal information to any external server. All detection and blocking operations are performed locally on the user's device.

The extension is intended solely to enhance user privacy and email security by reducing unwanted tracking within webmail interfaces.
