Tor Browser uses the Tor network to protect your privacy and anonymity. Using the Tor network has two main properties:
Your internet service provider, and anyone watching your connection locally, will not be able to track your internet activity, including the names and addresses of the websites you visit.
The operators of the websites and services that you use, and anyone watching them, will see a connection coming from the Tor network instead of your real Internet (IP) address, and will not know who you are unless you explicitly identify yourself.
In addition, Tor Browser is designed to prevent websites from “fingerprinting” or identifying you based on your browser configuration.
