How Exposed Are You Online? A 30-Second Privacy Audit
How Exposed Are You Online? A 30-Second Privacy Audit
Most people think they’re safe online because they “use a VPN.” But a VPN is only one layer of many. Your browser leaks data in ways most people never consider.
What Your Browser Reveals About You
Every time you visit a website, your browser sends:
- Your IP address (even through some VPNs via WebRTC)
- Your exact browser and OS version (User-Agent header)
- Your timezone and language (Accept-Language header)
- Your screen resolution and GPU model (JavaScript fingerprinting)
- Your installed fonts (Canvas fingerprinting)
- Your DNS queries (potential DNS leak)
Combined, these create a unique “fingerprint” that can track you across websites — even without cookies.
The Privacy Audit
I built a free tool that tests all of this in 30 seconds:
- IP Exposure — Is your real IP visible? Is it behind a VPN?
- DNS Leak Test — Are your DNS queries going to your ISP instead of your VPN?
- HTTP Headers — What does your User-Agent and Accept-Language reveal?
- Browser Fingerprint — How unique are your GPU, screen, and hardware?
- WebRTC Leak — Can WebRTC bypass your VPN and expose your real IP?
- Connection Security — Is your connection encrypted?
You get a score from 0 to 100 with specific findings and severity ratings.

How to Fix What It Finds
I also wrote a comprehensive Privacy Hardening Guide covering:
- Firefox about:config settings that matter
- DNS-over-HTTPS setup for every OS
- VPN kill switch configurations
- Browser fingerprint reduction
- WebRTC disable instructions
- OS telemetry removal (Windows, macOS, Linux)

Why I Built This
Most privacy tools are built by VPN companies trying to scare you into buying their product. This one is built by a developer, runs on a server, and has zero ads or tracking.
