An anonymous proxy is a proxy that does not reveal the client's original IP to the destination server via HTTP headers.
Explanation
The classification comes from what the proxy does with the X-Forwarded-For and Via HTTP headers. A transparent proxy adds both headers, so the destination sees your original IP. An anonymous proxy omits the X-Forwarded-For but sends Via — the destination knows a proxy is involved but not who is behind it. An elite (or high-anonymity) proxy omits both headers — the destination cannot tell there is a proxy at all. The classification only matters at the HTTP header level; it does not affect TLS, cookies, browser fingerprinting, or account-based tracking. AnyProxy is functionally anonymous — we do not forward your client IP to destinations. But "anonymous proxy" is not the same as "you cannot be tracked" — the destination site still sees cookies, browser fingerprints, and any account you sign into.
