What is a good keyboard app for Android?

I've been using SwiftKey for over a decade now, and I didn't really realize how potentially horrible it is for privacy. What are some good alternatives you guys can suggest, ideally open source?

My ideal keyboard includes swipe to type and a notepad (to paste certain emoticons like shrug emoji and such).

Thank you!

Edit, for any future lemmings/internet people who want the definitive answer (so far, as of October '23), OpenBoard works great.

Download the latest release apk from here

And if you want swipe typing as well,

Download the "libjni_latinimegoogle.so" file onto your phone from here

Then when you open OpenBoard, go to Advanced and select "Load gesture typing library". When it asks you to select a file, select the "libjni" file and swiping should work just fine.
