About Modern T9

Nine-key predictive text for current Android, and nothing else. Modern T9 declares no permissions at all — without the INTERNET permission the system would refuse a network connection even if the keyboard attempted one. A keyboard is the most privileged app on a phone: it sees every password, every message, every search. Modern T9 is built so that privilege costs you nothing. Privacy by construction - No INTERNET permission and no networking code of any kind. - No analytics, ads, telemetry or crash reporting. - Learned words and saved phrases stay in app-private storage, as plain text files you can read yourself. - Clipboard history is held in memory only and is never written to disk. - Android's backup carries your settings and deliberately leaves your dictionary behind. Typing - Real T9 prediction over English (US) and Spanish (Latin America) dictionaries — one language at a time, or both at once. - ABC multi-tap when you would rather spell a word out letter by letter. - A strip down the left side for saying which letter a key meant, accented forms and ñ included. - Saved phrases for email addresses, URLs and handles: tap the first few keys of the code and the whole thing is offered. - It learns the words you actually use, so they move to the front over time. - Long-press a key for accents and symbols; flick a key downward for its digit. - Closing punctuation attaches to the word you just finished instead of drifting off after a space. - Tap into a word to reopen it and choose a different spelling in place. - An editing pane with cursor keys, selection, copy, cut, paste and undo. A clipboard history. An emoji picker. - Adjustable keyboard height and clearance above the navigation bar. The prediction engine sits behind a small interface and is a replaceable module, so a different backend can be dropped in without touching the keyboard itself.
