I know someone who'll love it.

Now I'm wondering if there's anything similar showing what your average commercial social media, games and AI chatbot apps are collecting...

Well done on the part of this old version of 's built in browser for spoofing half the results to obscure my identity! I wish it blocked the power API though...

I do have a small gripe with safari because they disabled gyro suddenly about a decade ago without even leaving an option for the website to request gyro access via a dialog, thus breaking some genuinely cool web apps. There was a better way thru could have done it while still blocking silent gyro access

Without cookies. Without accounts. Without a name. The technique is called browser fingerprinting. It is legal in most jurisdictions. It is happening on most pages you visit. None of them mention it."

There are also browser extensions that can change your User Agent (the metadata that tells websites your OS, browser, etc). That will pretty much cover everything.

Keep in mind that the website uses spooky language for what are either generic browser APIs, or plain old fundamental functions of the Internet.

Each data point alone is not important in itself, no more than any single ridge on the tip of your finger. It is the combination of them all into a whole that makes a unique fingerprint, that strips away your anonymity on the internet.

Once you become a known entity, your dossier can be fleshed out, bought, and sold. The US government has been buying this information, no warrant required. Anyone could.

like, the "what renders your world" tells me nothing about how this information can actually be weaponized in any way.

or how it can tell what fonts i have. So? it gives no explanation for why this is dangerous (if it even is)
