What Information Does Your Browser Reveal?
Every website you visit can access a surprising amount of information about your device. This includes your IP address, browser details, operating system, language, and more. Browser fingerprinting is the practice of combining these data points to create a unique profile of you—often used by advertisers, analytics platforms, and even fraud prevention systems.
Did you know? Even if you use a proxy or VPN, your browser details may still uniquely identify you across sites.
- Browser fingerprint: A unique combination of your settings, plugins, fonts, and more.
- IP address: The main clue to your real-world location.
- Proxies/VPNs: Can hide your IP, but not all browser details.
Websites combine browser and connection details into a unique profile.
How Do Proxies and VPNs Affect Browser Fingerprinting?
Proxies and VPNs are important privacy tools, but they have limits. They typically hide your real IP address, but browser fingerprinting uses other clues (like your browser version, fonts, and plugins) to track you—even if your IP changes.
| Data Point | Proxy/VPN Hides? | Visible to Websites? |
|---|---|---|
| Your IP Address | Yes | Proxy/VPN IP is shown, not your real one |
| Browser/OS Info | No | Your real browser & OS are always visible |
| Screen Resolution, Language, Timezone | No | Can be used for fingerprinting |
| Cookies/Tracking Scripts | No | Sites can still set/read cookies |
| DNS Requests | Sometimes | May leak if DNS is not protected (DNS leak) |
| Browser Plugins/Fonts | No | Used in advanced fingerprinting |
Tip: For maximum privacy, combine a VPN or trusted proxy with a privacy-focused browser and disable unnecessary plugins.
Frequently Asked Questions: Browser Privacy & Proxy Checks
A browser fingerprint is a unique profile built from your browser and device details—like version, OS, fonts, screen size, plugins, and more. Trackers can use this fingerprint to recognize you even if your IP address changes. Think of it like a digital passport that follows you across websites.
No, proxies and VPNs primarily hide your IP address but do not change your browser's fingerprint. Websites can still recognize your device based on other details. For stronger privacy, use privacy-focused browsers, disable unnecessary plugins, and consider tools designed to randomize your fingerprint.
Use browsers with built-in privacy protections (like Brave or Firefox with privacy add-ons), block trackers, disable or limit plugins, and regularly clear cookies. Avoid using rare fonts or browser versions. Remember, no method is foolproof, but these steps make you harder to track.
Not all extensions are safe—some can track your browsing or even inject ads. Only install trusted extensions, review permissions carefully, and periodically audit what you have installed. Privacy extensions can help, but too many or rare ones may actually make your fingerprint more unique.
At a minimum, every website can see your IP address, browser version, operating system, screen size, and language. Most also collect your User-Agent, JavaScript status, and timezone. With cookies or scripts, they can track you across sessions and sites.
Your IP address is your unique identifier on the internet—like a street address for your device. A browser fingerprint is a combination of settings and features that can track you even if your IP changes. Both can be used to identify or follow you, but in different ways.
Incognito or private mode prevents your browser from saving history, cookies, and some site data. However, it does not change your IP, fingerprint, or protect you from trackers on the websites you visit. For true privacy, combine incognito mode with other privacy tools.
Use tools like this browser check, and compare your real IP with the one shown here. To test for DNS or WebRTC leaks, use specialized tools or privacy-focused browsers. If your real IP or location leaks despite using a proxy/VPN, you may need to adjust your settings or switch to a more reliable provider.
