關於 瀏覽器洩漏檢查
檢查瀏覽器睇到嘅 IP、WebRTC 同 DNS 路徑
A browser leak check describes what this browser and network exposed during one run. It cannot read the operating system proxy setting directly, and a result is not a complete anonymity, VPN, or security audit.
點樣用呢個開發者工具
- Run the direct browser checks to see the IPv4 and IPv6 paths visible to the page.
- Review local and server-reflexive WebRTC candidates and compare them with the VPN or proxy behavior you expect.
- Wait for the one-time DNS probes to finish and review the resolver signals returned by the controlled probe domains.
- Repeat after changing browser, VPN, proxy, or network settings, and confirm important findings with the provider's own documentation.
私隱同資料處理
This tool runs in the browser. It gathers WebRTC candidates locally, connects to configured IP detection endpoints, and makes one-time DNS probe requests to controlled domains. It does not send browser-leak results to this site's server, and it cannot read system proxy settings or collect proxy credentials.

常見問題
Can a website read my system proxy setting?
No. A normal web page cannot directly inspect the operating system's proxy configuration. It can only compare the network paths and signals exposed by the browser.
What does a WebRTC candidate reveal?
A candidate can show a local, server-reflexive, relay, or mDNS-hidden path exposed for WebRTC. Its significance depends on browser policy, VPN design, and the application using WebRTC.
What does a DNS leak result prove?
It indicates which resolver path handled the probe requests observed by the controlled domains. It is a useful signal, not a complete inventory of every DNS request from the device.
