What does a VPN actually do?
A VPN wraps your internet traffic in encryption and routes it through the VPN company's server before it reaches the open internet. Two things follow: your internet provider, employer, or coffee-shop network sees only that you connected to a VPN, not which sites you visited, and the sites you visit see the VPN server's location and IP address instead of yours.
What a VPN does not do is make you anonymous. Websites still recognize you the moment you log in, browser fingerprinting and cookies still track you, and, crucially, you have relocated your trust rather than eliminated it: the VPN provider can now see everything your ISP used to. That makes free VPNs, which have to monetize somehow, a bad bargain.
Legitimate uses: public Wi-Fi protection, reaching region-locked content, and keeping browsing habits from your ISP. For anything beyond that, a VPN is one tool, not an invisibility cloak.
A VPN encrypts your traffic and routes it through another server, hiding activity from your local network and your IP from websites. It does not make you anonymous, and yes, they can see your traffic instead.
