"Simple Keyboard"
Gboard is a data hoarding extension of a devil and Swiftkey infuriated me with its stupid letter capitalizations, spaces after periods and all the other nonsense I wasn't able to turn off and it kept on forcing on me. So I threw all of it away and started using Simple Keyboard. It has like zero features, not even smileys so I returned to using ASCII ones again. Which means it also has zero chances to piss me off. And it's not sending everything I type anywhere. Since it has no spellchecker I actually bother to type right which all the other keyboards made me lazy and sloppy. So, there you have it.
