What is Browser Information?
Every time you visit a website, your browser introduces itself. It says, "Hi, I am Chrome version 124, running on Windows 11, and I have a 1080p screen." This introduction is necessary so the website can look good on your device. However, this same information is a Privacy Risk because it makes your device look different from everyone else's.
The Digital Mirror
Think of our Browser Info Tool as a digital mirror. We show you exactly what every website sees when you land on their page. By checking this data on AirOI Checker, you can see if your browser is being too "chatty" about your private hardware details.
How Tracking Works Without Cookies
Most people think that deleting cookies stops tracking. But today, companies use Fingerprinting. They combine your screen size, your battery level, and your installed fonts to create a unique ID. Even if you use a VPN, these hardware details don't change, meaning you can still be recognized.
Steps to Improve Your Privacy
If you feel like you're sharing too much, here are three simple ways to stay safer:
-
Switch to Brave: This browser automatically "muffles" your browser's info so trackers get fake data.
-
Update Regularly: Newer browser versions have better privacy shields against modern fingerprinting tricks.
-
Use Firefox: You can turn on "Resist Fingerprinting" in the advanced settings to look like a standard, generic device.
