Last Updated: November 28, 2025

OVERVIEW

CrossOver Compatibility for Steam is a browser extension that displays CrossOver compatibility information on Steam store pages. This privacy policy explains how the extension handles user data.

Specifically, we do NOT:

• Collect any personally identifiable information
• Track your browsing history or behavior

HOW THE EXTENSION WORKS

When you visit a Steam store game page, the extension:

1. Reads the game name from the page you are viewing
2. Sends requests to CodeWeavers.com to fetch CrossOver compatibility data
3. Sends requests to ProtonDB.com to fetch additional compatibility information
4. Displays the results directly on the Steam page

All requests are made solely to retrieve publicly available compatibility information. No user data is included in these requests.

THIRD-PARTY SERVICES

The extension communicates with the following external services:

• CodeWeavers.com (CrossOver compatibility database)
• ProtonDB.com (game compatibility information)
• Steam API (game details)

These services have their own privacy policies. The extension only retrieves publicly available information from these services.

PERMISSIONS

The extension requires host permissions for:

• store.steampowered.com (to display compatibility info on Steam pages)
• codeweavers.com (to fetch CrossOver compatibility data)
• protondb.com (to fetch ProtonDB compatibility data)

These permissions are used solely to provide the extension’s core functionality.
