GMail Hilite

Privacy Policy

Last updated: April 17, 2026

      GMail Hilite does not collect, transmit, or store any personal data on any server. All data stays on your device.
    

What the extension does

GMail Hilite reads your Gmail inbox to identify email attributes (starred status, read/unread state, labels, and sender address) and applies background and text color highlights to inbox rows based on rules you configure. This processing happens entirely within your browser.

Data we collect

We collect nothing. Specifically:

No email content is read or stored
No sender names or email addresses are stored or transmitted
No browsing history is recorded
No analytics or telemetry are collected
No third-party tracking scripts are included

Your settings

The highlight rules and colors you configure are saved using Chrome's built-in chrome.storage.sync API. This means:

Your settings are stored locally in your Chrome profile
Chrome may sync them across your own signed-in devices via your Google account — this sync is handled entirely by Google/Chrome, not by this extension
Your settings never leave your devices via this extension

Permissions

The extension requests two permissions:

storage — to save your highlight rule preferences locally
host access to mail.google.com — to read inbox row attributes (starred, unread, labels) and apply highlight styles

Neither permission is used to collect or transmit data.

Third-party services

GMail Hilite does not use any third-party services, APIs, or analytics platforms.
