One of the most significant ways you leak private data while using the internet is through your browser. No VPN can help you; this is largely unconnected to the service they provide.
But what information precisely is being logged? Here are 10 types of data that your browser is (probably) collecting about you.
1. Hardware and Software
Your browser collects data about your hardware and software.
In terms of software, your browser knows your operating system, IP address, browser, and browser plugins. From a hardware standpoint, your browser collects information about your CPU, GPU, and battery.
To restrict the amount of hardware and software data that your browser leaks, use a privacy-focused plugin like NoScript.
2. Connection Information
Your browser knows about your connection to the web. That information includes your IP address and browser speed.
A website can accurately estimate your location, even if you’ve not given it access to your GPS coordinates. Instead, it can use the Google GeoLocation API. Even if you’re accessing the web from a browser on a mobile device, it will be accurate to within 30 miles.
