Homebrew is a package manager that lets you install stuff from the Terminal. Lately it has started to collect analytics. Here’s how to disable Homebrew analytics.

According to their GitHub page, Homebrew’s anonymous user and event data have a 14 month retention period, which is the lowest possible for Google Analytics.
