Steam Wishlist Rank does not collect, sell, or transfer personal data.
The extension stores a local cache of public Steam wishlist ranking data in the browser using chrome.storage.local. This cache is keyed by Steam app ID and contains rank, estimate, game name, source, and timestamps.
The extension reads the current Steam app ID from Steam store app pages and requests a static JSON feed hosted on GitHub Pages. It does not send the developer a user's browsing history, Steam account information, or personal identifiers.
Network responses are treated as data only. The extension does not load or execute remote JavaScript or WebAssembly.
