Free Browser Privacy Checker – No Data Leaves Your Device
Welcome to Web tool Bazar's Privacy Checker. This tool helps you understand what information your browser exposes to websites. By running a series of local tests, you can see whether your privacy settings are effective and if there are any leaks, such as WebRTC revealing your local IP address.
🔍 What Does This Tool Check?
- Do Not Track (DNT): Indicates whether you've asked websites not to track you (though it's voluntary).
- Cookies Enabled: Checks if your browser accepts cookies.
- WebRTC Leak: Detects if your local IP address can be discovered via WebRTC, a common privacy leak.
- User Agent & Platform: Shows the browser and OS information shared with sites.
- Language & Timezone: Reveals your preferred language and timezone, used for fingerprinting.
- Screen Resolution & Color Depth: Part of your device fingerprint.
- Touch Support: Indicates if your device has a touch screen.
📋 How to Use
- Click the "Start Privacy Check" button. The tool will immediately gather information from your browser.
- Review the results in the table. Each entry shows a status or value.
- If you change any browser settings (e.g., enable DNT), click "Re-run Check" to see the updated results.
⚙️ Technical Details
All tests are performed using JavaScript APIs available in modern browsers. For WebRTC, we attempt to create an RTCPeerConnection and collect candidate IPs (with a timeout). This only reveals local network addresses (e.g., 192.168.x.x) and not your public IP. The test is safe and does not establish any external connection.
Limitations: Some tests may not work on older browsers or in certain secure contexts (like some mobile browsers). The WebRTC test may return "No leak detected" if the browser prevents IP discovery or if no candidates are gathered in time.
🧐 Frequently Asked Questions
Is this tool really private?
Yes. The entire check runs in your browser; no data is sent to any server. You can disconnect from the internet and it will still work (except for WebRTC which may rely on network interfaces).
What is WebRTC leak?
WebRTC is a protocol for real‑time communication. In some browsers, it can reveal your local IP address even when using a VPN. This test checks if your browser exposes such addresses.
Can I improve my privacy based on these results?
If you see a WebRTC leak, consider using a browser extension that disables WebRTC or switch to a more privacy‑focused browser. Enabling Do Not Track and blocking third‑party cookies also helps.
Why is my user agent considered privacy‑related?
The user agent string is sent to every website and can be used to fingerprint your browser. It reveals the browser, version, and operating system.
Does this tool check for tracking cookies?
It checks if cookies are generally enabled, but not for specific tracking cookies. For that, you'd need a dedicated scanner.
