Privacy Policy — W3global Echo

Overview

What is W3global Echo?

W3global Echo is a Chrome extension that adds email open and click tracking to Gmail. When you send a tracked email, Echo records when the message is opened by the recipient and whether any links are clicked. Results are displayed on your personal Echo dashboard.

This policy explains what data is collected, how it is used, and your rights regarding that data.

Data Collection

What data is collected?

Echo collects only the minimum data required to provide email tracking:

Your Gmail address — used to associate tracking records with your account.
Recipient email addresses — collected at the moment you click Send, used to identify which recipient opened the email.
Email subject line — used as a label in your dashboard. The email body is never read or stored.
Open events — timestamp recorded when a tracking pixel embedded in the sent email is loaded by the recipient's email client.
Click events — timestamp recorded when a recipient clicks a tracked link in the email.

      Important: The body content of your emails is never read, accessed, or stored by Echo. Only the subject line and recipient addresses are used.
    

Data Use

How is data used?

All collected data is used exclusively to provide the email tracking service to you:

Displaying open and click counts on your Echo dashboard.
Showing a live activity feed of recipient interactions.
Associating tracking events with the correct sent email and recipient.

Data is never used for: advertising, profiling, analytics sold to third parties, or any purpose unrelated to the tracking features you explicitly use.

Data Storage

Where is data stored?

All tracking data is stored on your organisation's own server at echo.w3global.com, which is operated by W3global. Data is not transmitted to any third-party service, analytics platform, or advertising network.

A small send-queue is temporarily stored in your browser's sessionStorage to ensure reliable delivery of tracking registrations. This queue is cleared automatically after successful transmission and is not accessible outside your browser session.

Chrome Permissions

Why does Echo need these permissions?

mail.google.com — Required to run inside Gmail, read recipient addresses from the compose window, and inject the tracking pixel at send time.
echo.w3global.com — Required to register tracking records and retrieve your saved templates from your Echo server.
alarms — Used to keep the Chrome service worker alive so tracking registrations are never lost due to browser idle termination.

Security

Remote code execution

W3global Echo does not execute any remote code. All extension scripts are bundled locally within the installed package. The extension never uses eval(), dynamic <script> injection, or any mechanism that loads executable code from a remote source.

Third Parties

Data sharing

W3global Echo does not sell, rent, share, or otherwise transfer any user data to third parties. All data remains within your organisation's own Echo server.
