Is ProtonDB for Steam safe?
ProtonDB for Steam sends Steam app IDs from store pages to ProtonDB to retrieve compatibility ratings.
When you browse Steam store pages, search results, or app links, the extension extracts Steam app IDs and requests ProtonDB rating data for those games. Those requests send the app ID in the path or query string to ProtonDB so the extension can display compatibility and Steam Deck badges.
