Using Tor makes it more difficult to trace a user's Internet activity. Tor protects personal privacy by concealing a user's location and usage from anyone performing network surveillance or traffic analysis.[9] It protects the user's freedom and ability to communicate confidentially through IP address anonymity using Tor exit nodes.[10]
