You don’t need to enable Allow Full Access to use the whole app. It works fine out of the box, but you’ll only be able to use the default theme without keypad tap sounds. You only have to enable Allow Full Access if you want to use the other colour theme and hear the keyboard tap sounds.
Your sensitive data and keystrokes are safe as the app does not store any information on any external server.
Yes you can. Apart from Twi and Fante, you can use it to type Ewe and Ga. It comes with all the additional letters for these languages. Below is a list of how to type the additional characters used in Ewe and Ga.
Yes I know a lot of apps on the App Store these days are free, but most of these apps have tricky ways of making you pay to continue using them or unlock certain features.

I have no plans for other platforms.
