About Our Toolbox & VPN Security

Are these online tools safe to use?

All online tools provided by TongBao VPN run entirely in your browser locally and never upload any data to servers. Whether it's IP detection, DNS leak testing, or password generation, all computations are performed client-side, ensuring zero data leakage. Our tool code is fully transparent and open for security researchers to audit.

Why should I regularly test for IP and DNS leaks?

Even when using a VPN, WebRTC and DNS leaks can still expose your real IP address. Changes in network environment, browser updates, or system configuration can introduce new leak risks. TongBao VPN recommends testing at least once a month with our tools to ensure your VPN protection remains effective and your online privacy stays protected.

How do I choose the right privacy protection tool?

Choose tools based on your needs: use IP detection and DNS leak test if concerned about IP exposure; use browser fingerprint test to understand tracking risks; use the password generator for secure passwords. TongBao VPN recommends combining a VPN with these detection tools to build a complete privacy protection system for comprehensive network security.
