About HeliBoard

HeliBoard is a privacy-conscious, open-source Android keyboard based on AOSP and OpenBoard. It requires no internet permission and works 100% offline, ensuring your keystrokes never leave your device. HeliBoard supports custom dictionaries for spell check and suggestions, customizable keyboard themes with dynamic color support on Android 12+, multilingual typing, clipboard history, one-handed mode, split keyboard, and a number pad. Custom keyboard layouts can be created and shared as plain text files, and emoji search is available via an optional emoji dictionary. Glide typing is supported through an optional closed-source library. Settings and learned word data can be backed up and restored. HeliBoard is available on F-Droid, IzzyOnDroid, and GitHub Releases, and is funded in part through the NLnet NGI Mobifree Fund with support from the European Commission.
