Description

From the listing uploaded by “appupdater”.

Design your custom keyboard – ad-free, no data tracking, pro tools included. At a glance: • Every key, every layout, every function fully customisable • No permissions, no ads, zero data collection • Keyboard for Android phones, tablets and Wear OS smartwatches • 40+ languages with word lists and auto-correction • Free base package · pro packages (EDP, EKP) optional via in-app purchase • EDP for example Multi-press and multiple functions per key • EKP for example Code Block Editor for developers More than just colours: The Keyboard Designer is a complete keyboard that works in every app. Unlike other keyboards, you don't just tweak colours — you build the whole keyboard: arrange keys freely, set sizes, choose labels, assign any function to any key. No other keyboard offers this kind of control. Privacy guaranteed: The app requests no permissions whatsoever — not even internet access. That makes it technically impossible for anything you type to leave your device. Passwords, private messages, contact info stay where they belong: with you. What a good keyboard must deliver: 1. No internet connection You enter very private data through a keyboard. A keyboard must therefore not request internet permission — only then can your input be guaranteed to stay on your device. 2. Individual adjustments The keyboard is the most-used app on a mobile device. It must fit the user perfectly — key arrangement, size, labels, colours, functions. With Keyboard Designer you decide every detail. 3. Easy to use Limited screen space makes typing hard. Helpers like the enlarged edit bar, big keys and smart actions keep the keyboard usable in tough conditions — walking, one-handed, for people with motor impairments. 4. Speed A keyboard must respond instantly. This app does not use the system keyboard API but renders all keys as optimised graphics. Input is noticeably faster. Highlights of recent versions: • Multi-press: assign multiple functions to a single key, picked by how often you press it • Auto-correction with bigram context for whole sentences, not just single words • Code Block Editor with syntax highlighting for developers • Stickures: hand-drawn symbols as input gestures • Hardware keyboard mode for Bluetooth and USB keyboards Packages: • Base (free): full keyboard, create your own designs, up to 4 rows, 12 keys per row • Extended Design Package (in-app purchase): unlimited rows and keys, design import/export, rounded keys, colour gradients • Extended Keyboard Package (in-app purchase): advanced function types like code editor, hardware keyboard support More info: https://edp.keyboarddesigner.com and https://ekp.keyboarddesigner.com Tutorials: https://www.tutkey.de (YouTube) Stickures gallery: https://www.stickure.com Made in Sauerland, Germany Note: When you select the keyboard, Android shows a default notice that keyboards can collect data. This notice appears even for keyboards without internet permission — and Keyboard Designer has none.
