AdaptKey is an adaptive Android keyboard (IME) that learns how you type - built for privacy first. Provably offline. No phoning home. AdaptKey has no internet permission at all. This is not a promise you have to take on faith - it is enforced by Android and verifiable by anyone: there is no INTERNET permission in the app manifest, so the operating system makes it impossible for the app to open a network connection. No telemetry, no analytics, no "anonymous usage statistics", no ads, no cloud sync. * No internet permission - kernel-enforced, not a checkbox you trust. * No storage permission - the optional local AI model is imported through the system file picker, which grants access to just that one file. * Everything runs on-device. Dictionaries, autocorrect, language detection and the optional mini-LLM all execute locally. * Free software, licensed under GPL-3.0-or-later - audit every line yourself. Features * Gboard-style QWERTZ/QWERTY layout with freely configurable key proportions (space bar, comma, full stop, backspace), a persistent number row, and per-key long-press secondary symbols. * Learns your touch pattern. A per-key personal offset model adapts hit detection to how you actually tap; an optional calibration step seeds it. * Smart suggestions and autocorrect from a personal on-device dictionary, with a stabilised suggestion bar, a "keep as typed" escape hatch, and one-tap post-commit undo. * Real multilingual dictionaries as optional downloadable language packs (German, English and Greek bundled to start with, more to follow), with on-device language detection that switches the whole lexicon per language. * Greek input with its own layout and accent long-press. * German capitalisation done right: sentence starts, nouns vs. proper nouns, hyphen segments, the e-mail-salutation comma rule, abbreviations, and a configurable shift-grace window. * Retroactive fixes: missed-space word split and spurious-space merge, driven by touch ambiguity. * Gestures: s
