In iOS, users can find the updated text by navigating to Settings > Safari and clicking on the About Safari Search & Privacy link underneath the Privacy & Security section, as shown above.
"Before visiting a website, Safari may send information calculated from the website address to Google's Safe Browsing and Tencent's Safe Browsing to check if the website is fraudulent. These safe browsing providers may also log your IP address," the privacy notice states.
This is part of the Fraudulent Website Warning option that is turned on by default in iOS. Unfortunately, Apple does not specify under what conditions browsing data and a user's IP address might be sent to Tencent instead of Google.
It's also not clear when this change took place, though one user on Twitter claims it dates back to at least the iOS 12.2 beta in February.
While there is no obvious nefarious intent, Johns Hopkins University professor and cryptographer Matthew Green says the change is still concerning because of how stealthily it was implemented.
"It increasingly feels like Apple is two different companies: one that puts the freedom of its users first, and another that treats its users very differently. Maybe Apple feels it can navigate this split personality disorder and still maintain its integrity. I very much doubt it will work," Green continued.
Whether or not Tencent collects this data outside China is unknown. However, we have confirmed the updated privacy text does appear in iOS 13 on devices in the US.
