Apple will stop sending secure browsing alerts via Google's servers from iOS 14.5.
Apple uses "proxy.safebrowsing.apple" instead of Google's servers
Instead, they should send the information via their own servers to stop Google from seeing information about users.
Google does not know which website is visited, but the IP address can be logged using Safari, but this will cease from iOS 14.5 and iPadOS 14.5.
This security feature is linked to a list maintained by Google that contains dangerous or scam-linked websites. If you visit such a page, a warning page will appear.
In addition to this improvement, iOS 14.5 makes it possible to block cross-advertising from, among others, Facebook and its partners.
