Privacy is a stack, not one switch
Hiding your IP address is useful, but it is only one part of online privacy. Websites can still use cookies, logins, device signals, browser fingerprints, payment details, and account behaviour to recognise you.
A practical privacy setup usually combines a trustworthy VPN, leak checks, stronger passwords, safer browser settings, and basic device security. The right mix depends on whether you are protecting public WiFi browsing, reducing advertiser tracking, checking location exposure, or securing accounts.
