The destination sees a request from the proxy region's IP address, not yours. Your cookies and account still identify you if you sign in.
Full answer
When AnyProxy fetches a page for you, the destination site receives a request originating from our proxy server. From the destination's perspective, the request source is the proxy's IP address in the region you selected (Frankfurt, Singapore, Virginia, etc.). The destination cannot see your device's real IP through this mechanism. That is what enables geo-unblocking — if the destination geo-blocks based on IP, a proxy region in a supported country presents a supported IP. But three important things the destination still sees: (1) Cookies from previous visits — if you have an existing session with the site, the site recognises you. (2) Your browser fingerprint — user agent, screen size, installed fonts, and hundreds of other signals that identify your device across sessions. (3) Any account you sign into during the proxied session — sign-in explicitly identifies you regardless of IP. So a proxy hides your IP but does not make you anonymous. For anonymity, additional layers (fresh browser profile, Tor, no sign-in) are needed. For unblocking access, IP change alone is usually sufficient.
