Incognito mode (or "Private Browsing") primarily prevents your local device from saving your browsing history, cookies, and site data, but it does not make you invisible to the outside world. While your browser won't show the sites you've visited after you close the window, your activity remains fully visible to your Internet Service Provider (ISP), your employer (if using a work network), and the administrators of the websites you visit. Additionally, your device's DNS cache can still store records of the domains you accessed during an incognito session, which can be viewed through technical commands like ipconfig /displaydns on Windows. Furthermore, search engines like Google may still associate your activity with your account if you log into a service (like Gmail or YouTube) while in incognito mode. To truly hide your history from external entities, you would need to combine incognito mode with a Virtual Private Network (VPN), which encrypts your data and hides your IP address, or use a specialized privacy-focused browser like Tor.
