Tor

Tor, short for "The Onion Router," is a free software that enables anonymous communication on the internet. It works by routing your internet traffic through a series of volunteer-operated servers worldwide, hiding your IP address and encrypting your data at multiple layers—like the layers of an onion. This process makes it difficult for anyone to trace your online activities back to you. Tor is often used to access the dark web, but it also serves to protect privacy and freedom of expression in countries with censorship or surveillance.
