So, concerning privacy:
>How can you guarantee that you protect privacy?
For our offline version (Offline Privacy Keyboard), you can find in the Google Play Store that we do not require permissions to access the internet. (https://play.google.com/store/apps/details?id=ch.icoaching.w...). Our iOS version does not require "full access" for either version, online or offline. This way Apple makes sure no one (not even us) has access to what you type. Other keyboards (such as Google) require "Full access" or allow it be enabled at the explicit permission of the user (e.g. Swiftkey). Typewise does not even have this option. There is no other guarantee. Even a certification of a provider would not help, because they would have to check every update.
> Also, is the layout and key shape patented or is it an open standard?
Yes, the layout and key shape are patented internationally.
>>Also, is the layout and key shape patented or is it an open standard?
So if I spend time learning this, and then your company imposes unreasonable requirements to use the app, would I have no recourse/alternative, that doesn't involve the time going to learn the new layout going to waste?
