OpenBoard – FOSS Keyboard for Android which respects your privacy
I use AnysoftKeyboard (on F-Droid) [1]. I's pretty good, but has issues with the French apostrophe, that's often used to combine words.It also has multiple keyboard layouts, of which "terminal" compares favorably to hacker's keyboard. I like that it is configurable, and has a lot of text editing tools when swiping space up.I admit I lost some typing speed when I switched from the alternatives, but I'm happier with it.[1] https://anysoftkeyboard.github.io/
