You can try yourself by going to one of the IOS Safe Browsing test pages on your phone, and when the warning pops up click "Show Details". It'll either say Google or Tencent on the warning message, which should let you know which one got chosen for you.
Great. I disabled safe browsing probably back when it first appeared on my iPhone 3G or 4 and this test confirms I’m still not sending urls to anyone whilst surfing on my iPhone 11. Nice job preserving these settings over countless device upgrades.
For anyone else wanting to disable it (or at least learn more about it), the feature is labeled in iOS settings under Safari > Fraudlent Website Warning.
You've probably switched off Safe Browsing. I wouldn't advise anybody to do that unless they're _so_ sure that they don't need Safe Browsing that when (most likely rather than if) they get infected by Malware or fooled by Phishing they are confident they'd tell everybody they know what an idiot they are.
I have it switched off on my home PCs (but on for work). But then I also don't carry home insurance and when I was flooded I believe my first Facebook message began "This is probably a good time for you to say 'I told you so'" because that seems like the right sentiment.
