Modern T9 Emojis and Keyboards app for Android description

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.
  • Androids 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.
