What is incognito mode in a browser and what does it actually protect against?

Many users mistakenly believe that incognito or private browsing mode makes them completely anonymous on the internet. In practice, this tool solves a rather narrow task and is intended exclusively for local privacy. When you open such a window, the browser stops saving browsing history, entered form data, cache, and cookies on your device. This is convenient if you are logging in from a random computer or want to hide the fact that you viewed certain sites from other users of the same PC.

However, incognito mode does not protect you from external surveillance. Your internet provider still sees all the sites you visit, and a network administrator at work or school can easily track your traffic through the corporate router. Moreover, the owners of web resources you open see your real IP address and can identify your device via browser fingerprinting. Advertising trackers also continue to function in this mode unless you use special extensions to block them.

Incognito mode alone is not enough to achieve true online privacy. Instead, you should use a comprehensive approach that includes a reliable VPN service to hide your IP address, modern tools to block ads and tracking scripts, and regular clearing of your digital footprint. Incognito mode is simply a convenient broom that sweeps away traces inside your own house, but it doesn't hide you out on the street.
