Browser fingerprint stands for collecting information about you through your device fingerprint, which conveys the following data: your OS, keyboard preferences, hardware, geolocation, timezone, display size, browser, device memory, vendor, and many other attributes. Some advanced websites even know what apps you installed on your PC. All this data helps identify you out of a crowd with up to 99% accuracy.

Many people wrongly think they may go under the radar by using proxies or VPN services. The problem is, the two only change your location and encrypt your traffic — you are still at risk of being detected by your fingerprint. Not convinced? Although there is no browser fingerprint test helping you check browser fingerprints (how and what information is collected exactly), you can at least see what data your device transmits.

Cookies are blocks of data created by a web server when browsing a website and stored on your computer for a more convenient user experience. For example, you probably noticed that when you get back to watching a video on YouTube, it often continues right from where you left it off. That is cookies’ “magic”.

Unlike browser fingerprinting, cookies are more or less regulated (at least, in some countries). That is why a website often asks you to accept its cookie policy. Browser fingerprinting, on the contrary, happens stealthily, without even having you asked about it. And alas, neither clearing your cookies nor browsing history keeps you anonymous.

Most of today’s web browsers have built-in APIs. Websites use them for basically legal purposes, such as rendering videos and photos. Yet, they also help many websites collect data about users. This data is, again, supposed to be used for improving a website’s functionality only. In reality, however, such information often ends up being misused, as nobody presently regulates browser fingerprinting.

“Oh well, I am just a teacher doing nothing wrong; like, who cares about me, huh?” Wrong thinking. Even if you do not do anything illegal and are just a common man, your personal data collected by different websites may be turned against you. Lots of companies operating on the Internet exploit cross-site tracking. In other words, you are not just being tracked on a particular website but across the entire web.

Such information compiled can be sold to data brokers who work up files about everyone on the Internet. Combined with all the offline data they could get about you, these files are very likely to disturb your personal life. For instance, data brokers can sell this information to your bank, which could deny you a loan. Why? Because you have been lately showing too much interest in cryptocurrency and begun regularly investing in it. So, now the bank thinks you are a risky borrower. is a website that provides information about IP addresses. When you visit the site, it detects your IP address and displays information related to it, such as location, ISP, and whether it’s being used for a VPN or proxy server. It’s a tool for checking the public details associated with an IP address.

A browser privacy checker is a tool that helps you identify how much information your browser leaks online. This can include things like your IP address, browser version, and even unique details about your device that can be used to track you across the web.

Canvas fingerprinting is a technique that websites can use to create a unique “fingerprint” of your browser. This fingerprint is based on how your browser renders certain elements on a webpage. Even though no single piece of information might be very revealing, combining them can create a profile that’s unique to your device.
