It certainly appears not. They're using curl and reporting a UID they generate. A Homebrew analytics user ID e.g. 1BAB65CC-FE7F-4D8C-AB45-B7DB5A6BA9CB. This is generated by uuidgen and stored in ~/.homebrew_analytics_user_uuid. This does not allow us to track individual users but does enable us to accurately measure user counts vs. event counts https://github.com/Homebrew/brew/blob/master/share/doc/homebrew/Analytics.md https://github.com/Homebrew/brew/blob/master/share/doc/homeb... Of course, you have to trust homebrew, but hell, you're already running their software, so it's a little late.
