Do you sometimes wish that online advertisers had access to more of your private information without your consent or knowledge? Well, you might just be in luck.

As of February 16 2025, Google is permitting ‘fingerprinting’, which is a stealthy technique which tracks things like your IP addresses, screen resolution, operating systems, and even battery percentage - until it has a creepily accurate profile of you.

This practice will be particularly disturbing to the privacy-conscious among us since it's virtually impossible for users to control what information is collected and when. You can turn off all cookies, use all the private browsers, and use the best VPN money can buy, but you could still be tracked with this technique.
