As soon as youre connected to the Internet, applications can potentially send whatever they want to wherever they want. Most often they do this to your benefit. But sometimes, like in case of tracking software, trojans or other malware, they dont.
But you dont notice anything, because all of this happens invisibly under the hood.
Whenever an app attempts to connect to a server on the Internet, LittleSnitch shows a connection alert, allowing you to decide whether to allow or deny the connection. No data is transmitted without your consent. Your decision will be remembered and applied automatically in the future.
If you are new to LittleSnitch, you may get overwhelmed by the vast amount of notifications from applications wanting to connect to the Internet. The all-new Silent Mode was re-built from the ground up to make dealing with them a breeze. It lets you silence all notifications for a while, and make all your decisions later, conveniently with just a few clicks, in one go.
