In the case of a Chrome extension, only the browser traffic is encrypted and routed.

While a VPN uses a VPN protocol to encrypt all the traffic coming off your device and route it through a VPN server, a proxy can only encrypt and route the traffic from one app at a time. It's more likely it's an encrypted proxy. With exceedingly rare exceptions, a Chrome browser extension from a VPN service is not actually a VPN. Most Chrome Browser VPNs (Probably) Aren't VPNs Not all these extensions are as powerful as their sibling apps, however, and almost none of them work the same as true VPNs-they function differently and only protect your browser's traffic. Most VPN services provide apps for just about every platform, and many provide extensions for Google's Chrome browser.
