Predictive T9 keyboard with no network access and no telemetry
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.
