While the other responses so far have good info, none has offered a useful answer. Yes, apple collects data, but thankfully don’t sell it to the world. Buying a new phone isn’t a trivial expense so some of us are stuck for a bit. As a fellow IOS user (for now), I too would like to hear some more options.

The best I’ve found so far is Typewise. They claim to be private and secure but it’s closed source so so knows. Apple gets to review their code when submitting to the app store which says that Typewise collects some data but none of it is linked to the user. It’s freemium. Unfortunately, I don’t like their keyboard. Swipe typing is my personal requirement🙂
