Is hackers keyboard gonna steal my crap?

That's a standard warning for any keyboard you install. Hacker's Keyboard is just a name. It's named that way because it contains functions like the F1-F12 keys and other keys you find on a full PC keyboard, which incidentally, hackers use. As if normal people don't. But if you install Swiftkey or TouchPal keyboards, you still get that warning. Keyboard apps have functions that let them save the words you type for predictive purposes. Eventually they'll be able to predict whole sentences for you. It comes down on how much you trust the developers that they won't use what you type. I can't say for Hackers Keyboard, but I do believe that Swiftkey and TouchPal keyboards are from trustworthy developers. I've used them a lot over the years.

 

You turn off autocorrect in the keyboard settings. And I do not know of any keyboard that put it at the top of the screen. That just seems so unnnatural, that the keyboard be above what you are typing.
