This extension analyzes your CS2 case-opening history from Steam's inventory history page and breaks it down into detailed stats: total cases opened and money spent, drop rates by rarity (from mil-spec to gold), StatTrak item counts, your most-dropped items, and how many cases since your last knife. All calculations run locally in the browser with no data sent to external servers. It requires your Steam client set to English and the inventory history page loaded to work.

The extension only works if your Steam interface language is set to English — change this in your account settings.
Go to your Steam inventory, open the three-dot menu, select "Inventory History," then click "Load history" to fetch your records.
Once history loads, the extension automatically calculates rarity, StatTrak, and spending statistics.
The extension only needs access to your Steam inventory history page; all stats are calculated locally in the browser with nothing sent to third-party servers.
