Generally there are few privacy friendly/Foss browsers on IOS.

Um, Safari is so privacy friendly that Google regularly asks me if I'm human. For example it has "private relay" which is similar to TOR* so trackers don't even know your IP address — combine that with blocking third party cookies (and even some first party cookies) by default and providing false data to fight fingerprinting even if you don't block trackers entirely - and blocking them entirely is as simple as installing an extension. Private Relay also adds a layer of encryption on top of DNS queries and otherwise unencrypted http traffic.... so your ISP/Cellular provider/Work/School/abusive husband/etc can't track you

99.99% of the Safari's code is FOSS — dual licensed under LGPL and BSD.

It's not the browser I use - pretty lacking in the feature department, but it's definitely more pro-privacy than Brave or FireFox. I've never had to jump through a captcha to use Google in those browsers.

(* if anything, it's better than TOR... with that service there's a risk your entry/exit nodes are tracking you. With Private Relay it's always one of Apple's servers for the entry node and a reputable cloud company like Akamai for the exit node. Both would have to be compromised in order to identify you... maybe a nation state can do that, but a big data tracking company definitely can't)
