In plain words
Little Snitch 4 is a Mac application that monitors and controls internet connections made by apps on a user's computer. When an application attempts to connect to a server online, the software displays an alert letting the user approve or block the connection. Users can set rules to remember their decisions, preventing unwanted data transmission without explicit permission. It is designed for Mac users concerned about controlling which applications access the internet and what data they send.
