So I tried this site out.
With bytzs VPN it showed my real location, I switched to tor and it hid the location but still gave the correct timezone.
All on Brax3 with iode browser and brave.
Kinda crazy.
Hello, I tried the page with a free vpn called secure vpn and most everything reported was wrong and seemed to be generic. Hope this helps.
Same with tor except timezone was still right. Just weird that bytz was showing correct stuff.
