How GemMarker Works

Understanding how the extension operates helps clarify our privacy approach:

1

Local Processing

All extension functionality runs entirely within your browser. No external processing occurs.

2

Asset Interception

The extension intercepts specific game image requests and replaces them with colored overlays.

3

Local Storage

Your preferences (enabled/disabled toggles, panel position) are saved locally in browser storage.

4

No External Communication

The extension never sends data to external servers or third parties.

GemMarker requests only the minimum permissions necessary for functionality:

Host Permissions

Access to The Settlers Online domains only. Required to detect game pages and inject the control panel.

Storage
