When you use the Internet in normal mode, your device connects to the application and website servers directly. As a result, they recognize your IP address, location and other data - that is, you lose your anonymity on the Web. In addition, the owners of applications and sites or the provider may block your access to materials of interest.
Fortunately, instead of a direct connection, you can use a free proxy - an intermediary server that provides data exchange between the device and Internet resource servers. It masks your details from the owners of the apps and websites you visit, which prevents them from blocking you by IP. In addition, indirect connection allows you to bypass the restrictions imposed by the provider itself.
However, proxy servers provide only relative anonymity on the Internet.
With special equipment and skills, interested parties will be able to track you. However, with the help of a proxy, you can access many blocked sites and hide your IP from them.
