Thanks for sharing. Looks like a great tool. Unfortunately it requires allowing full keystroke access which is too much of a security risk.
Thank you for checking the app out! Ah that's too bad :(
I don't collect any data and the app only connects to the internet at launch (to check subscription status) and when you use the dictionary feature. You can choose not to allow full access and still use quite a few features!
Its a standard practice for third party keyboards on iOS, I doubt you'll find any keyboards worth using that don't request full access. Otherwise Apple cripples the experience a lot.
