The Keyboard Designer is a customizable keyboard app that can be used in all apps on your mobile device. It allows you to design your own keyboard or import pre-made keyboards after purchasing the extended design package. You can change the colors, arrange the keys, and assign functions to them. The app does not request access to the network, ensuring that all data remains on your device.

The keyboard must match certain requirements, such as no connection to the internet, individual adjustments, easy usage, and speed. The app meets these requirements by providing a simplified structure that reacts quickly to keypresses. It also offers example designs and the option to purchase the Extended Design Package for additional features.

When selecting the keyboard, a hint is shown by the system that the keyboard can collect data, even though it cannot send any data due to its lack of internet connection. The Keyboard Designer is made in Sauerland, Germany.

Overall, the Keyboard Designer is a useful app for those who want to customize their keyboard to their specific needs and preferences. It offers a range of features and meets important requirements for privacy and functionality.
