📚 How This Tool Works
Look, every time you're browsing the web, your browser's basically having a conversation about you behind your back. Sometimes it needs to share stuff so websites actually work. Fair enough. But there's a whole lot more going on that nobody tells you about. That's where this comes in—we're gonna show you exactly what's leaking out and, more importantly, what you can actually do to stop it.
How This Works
So here's the deal. Everything runs locally in your browser. Hit that scan button and all the tests happen right on your machine. Nothing gets uploaded, transmitted, or sent anywhere. We're checking what's exposed while keeping your privacy intact—kind of ironic otherwise, right? We dig into five key spots where browsers love to spill your secrets, then break down what we found in plain English.
What We're Testing For
WebRTC IP Leaks
Okay so WebRTC is this thing that lets you make video calls right in your browser. Zoom, Google Meet—all that stuff needs it. Cool feature, terrible for privacy. Why? Because even if you're running a VPN trying to stay anonymous, WebRTC can just straight up leak your real IP address anyway. I've seen people pay for fancy VPNs and then wonder why they're still getting tracked. Nine times out of ten, it's WebRTC stabbing them in the back. This test tells you if you've got that problem.
DNS Leaks
Think of DNS like your browser asking for directions every time you want to visit a website. "Hey, where does Facebook live?" "Where's Amazon?" Normal enough, except those questions aren't private by default. Your internet provider can see every single one. We're checking if your DNS requests are encrypted—because they really should be. Also, some browsers try to be "helpful" by pre-loading sites they think you might click on. Sounds nice until you realize it's broadcasting your browsing intentions before you've even decided what to do. Not great.
Browser Fingerprinting
This one's honestly kind of creepy when you first hear about it. Delete all your cookies, clear everything—doesn't matter. Websites can still recognize you just by watching how your browser acts. They check stuff like how it renders a simple image, which fonts are sitting on your computer, your screen resolution, even the way your audio hardware processes sounds. Each detail on its own? Whatever. But combine twenty of these little things and boom—you've got a fingerprint as unique as the one on your thumb. We're running the exact same tests the tracking companies run, just so you know what they're seeing.
Location Privacy
You know that popup asking "Share your location?" that you always click "No" on? Good instinct. Problem is, websites don't need that permission to figure out roughly where you are. Your timezone's a dead giveaway. Language preferences? Same deal. It's like telling someone "I won't tell you my address" but you're wearing a shirt that says "New York" and speaking with a thick accent. We'll show you what location breadcrumbs your browser's leaving around even when you think you've locked that down.
Cookies and Storage
Ah, cookies. The OG tracking method that everyone's heard of. Look, first-party cookies are totally fine—those are just the website you're on remembering you logged in or what's in your cart. No biggie. Third-party cookies though? That's where things get sketchy. Those are how advertising companies stalk you across the entire internet. You look at shoes on one site, then see shoe ads everywhere for the next month. That's third-party cookies doing their thing. We check if you're letting those through, plus all the other sneaky ways sites can stash tracking data on your computer. Spoiler: if we find third-party cookies blocked, that's actually you winning.
Pick How Deep You Wanna Go
Don't always need the full treatment. Choose whatever fits your situation:
- Complete Analysis - The whole shebang. Every test we've got. Takes maybe thirty seconds tops, but you'll get the complete picture of what's going on with your browser.
- Quick Privacy Scan - Just hits the highlights. WebRTC leaks, cookie situation, done. Perfect for when you wanna quickly check if that VPN's actually doing its job or verify some settings you just changed.
- Custom Test Suite - You're in control. Use those toggle switches down below to pick exactly what you want tested. Handy if you've been messing with specific privacy settings and want to see if they actually worked.
- Reset & Clear Data - Nukes all the results and starts over. Good for when you're comparing before and after, like testing different browser configs to see which one's better.
The Toggle Switches Explained
These little switches let you tweak how everything runs:
- Real-time Monitoring - Flip this on and you get a live feed showing what's going down with your privacy in real time. It's honestly pretty wild to watch. You'll see exactly when different browser features get pinged and what data they're grabbing. Kind of eye-opening.
- Deep Fingerprint Analysis - We turned this on by default because fingerprinting's become such a massive problem lately. It checks canvas stuff, WebGL, how your audio hardware sounds, fonts, the works. You can turn it off if you're only worried about network leaks and want the scan to finish faster.
- Network Leak Detection - This runs the WebRTC and DNS checks. Using a VPN or Tor? Keep this on for sure. If you're just browsing normally and don't care about network-level privacy, feel free to skip it.
- Verbose Reporting - We keep this off normally cause it dumps a ton of technical info that most people don't need. But if you want to see the actual IP addresses, exact fingerprint hashes, all the raw data—turn it on. It's there for the people who like to really nerd out on this stuff.
What Your Score Actually Means
Once it's done scanning, you'll see a number out of a hundred. That's just the percentage of tests you passed. Don't freak out if it's not perfect—honestly, most people score somewhere in the middle. Here's the breakdown:
- 85-100: Excellent Privacy - Nice work. Your browser's locked down tight. You're doing way better than the average person out there.
- 70-84: Good Privacy - Solid setup. You're ahead of most folks. Maybe a couple tiny things to tweak, but nothing urgent.
- 50-69: Moderate Privacy - Alright, there's definitely room to level up here. Maybe grab some privacy extensions or think about switching to a more privacy-focused browser.
- 30-49: Poor Privacy - Not gonna sugarcoat it—your browser's leaking more than it should. Got some real issues that need fixing sooner rather than later.
- 0-29: Critical Risk - Yeah, this is bad. Your browser's basically an open book right now. Whatever you're doing online, assume people can see it. Time to make some changes ASAP.
So What Do You Actually Do Now?
Found some issues? Cool, here's how to fix the most common stuff that pops up:
- WebRTC is leaking your IP - Go grab an extension called "WebRTC Leak Prevent" or just turn off WebRTC entirely in your browser settings. Real talk—unless you're doing video calls in your browser all the time, you don't need it on anyway.
- Third-party cookies are allowed - Hit up your browser settings and block those suckers. Takes literally two minutes. This is probably the single easiest win for your privacy. Sure, maybe one or two websites will whine about it, but like ninety-nine percent of sites work totally fine.
- Your fingerprint is too unique - Not gonna lie, this one's trickier. Firefox has this setting called privacy.resistFingerprinting buried in about:config that helps. Or just switch to Brave—that browser fights fingerprinting right out of the box without you having to do anything.
- VPN not hiding your real IP - It's WebRTC leaking again. Use that extension I mentioned, or honestly? Maybe time to switch VPN companies because if they're not handling WebRTC leaks, that's Privacy 101 stuff they're missing.
Real Talk About Privacy
Look, privacy's not some binary thing where you're either totally private or completely exposed. Perfect privacy? That costs you. Stuff breaks, sites don't work right, things get annoying fast. Everyone's got their own line between privacy and convenience depending on what they're protecting and what headaches they're willing to deal with.
Point is—you're not trying to score a hundred here. You're trying to understand what's leaking so you can make real decisions about what matters to you. Maybe you work somewhere that needs serious privacy. Maybe you just hate seeing creepy targeted ads follow you around. Maybe you're cool with most tracking but draw the line at location stuff. Whatever. Use this thing to see where you're at, patch up what bugs you, and stop worrying about the rest. Life's too short to stress about every little privacy leak if it doesn't actually affect your life.
