zinna-IME

An open-source Japanese input method for Android. Conversion is mozc — the engine behind Google Japanese Input's open-source release — compiled natively into the app rather than reached over a network. The app declares no permissions at all, INTERNET included, so nothing you type can leave the device even if a future dependency wanted it to. Input * Flick, QWERTY, or kana on flick with the alphabet on QWERTY * A second symbol plane for brackets, arrows, maths and typographic marks * While a key is held, either a preview of what releasing will type or the full cross of four directions — and the symbol plane can always show the cross, since nobody memorises where ※ is * Repeated presses of one key type the same character rather than cycling through it Conversion * Rule-based correction for mistyped readings, aware of where the keys actually sit on the flick layout: a slip within one key is treated as likelier than a hit on the neighbour * Candidates that convert exactly what you typed are ranked ahead of guesses about what you have not finished typing * Bundled dictionaries covering Niconico and Pixiv article titles, katakana loanwords with their English spellings, and Wikipedia headings Your data * The conversion history and your own dictionary are encrypted with a key held in the Android Keystore, which on devices with a secure element cannot be extracted at all * Everything you cannot recreate — your dictionary, what the engine has learned, your settings — exports to a single file sealed under a passphrase you choose, and imports back on any device * Clipboard history stays on the device and skips anything the source marked sensitive Appearance * Themes and keyboard layouts are plain JSON files you can replace * Dark mode, Material You, a background image of your own, adjustable key height, pure black for OLED panels
