Smart android keyboard respecting privacy?

Hello, could someone recommended a keyboard for android that is a bit smart in predictive typing? I used to like swiftkeybefore it was bought by microsoft. Not that swiftkey itself was much better but I was not so privy conscious at that time.

I recall swiftkey would require access to your texts and emails to train itself to your predictions.

Is there some similar foss keyboard where all the data then remains local?

I know swiftkey has an incognito mode, but then it stops learning from your typing.
