Traditional T9

TT9 is a Nokia-style 12-key T9 keyboard. It provides predictive text input in 50+ languages, configurable hotkeys, clipboard, undo/redo, and extensive customization. It works on touchscreens, physical keypads, and TV remote controls. And best of all, it doesn't spy on you!

Supported languages: Arabic, Belarusian, Bulgarian, Catalan, Simplified Chinese (Pinyin), Traditional Chinese (Bopomofo), Croatian, Czech, Danish, Dutch, English, Estonian, Farsi, Filipino, Finnish, French, German, Greek, Gujarati (phonetic), Hebrew, Hindi (phonetic), Hinglish, Hungarian, Indonesian, Irish, Italian, Japanese (Romaji), Kiswahili, Korean, Latin, Latvian, Lithuanian, Macedonian, Norwegian (Bokmål and Nynorsk), Polish, Portuguese (European and Brazilian), Romanian, Russian, Serbian (Cyrillic and Latin), Slovak, Slovenian, Spanish, Swedish, Moroccan Tamazight (Latin and Tifinagh), Thai, Toki Pona, Turkish, Ukrainian, Vietnamese, Yiddish.

Philosophy:
• No spying, tracking, telemetry, reports, or data collection of any sort.
• No ads or unnecessary bells and whistles. It only does its job, typing.
• No unnecessary network connections. The Full version operates entirely offline, and the Lite version connects only to download dictionaries from GitHub. Voice Input may require Internet access, depending on the available voice services.
• Open-source, permitting you to verify all the above yourself.
• Created with help from the entire community.
• Things it will (probably) never have: QWERTY layout, swipe-typing, GIFs, and stickers.
• Not intended as a clone of TouchPal, Sony Ericsson, KaiOS, Samsung, etc. While it captures the feel of the classics, TT9 offers its own experience and won’t replicate any device or app exactly.

Note: the Google Play version is almost identical to the lite version, except that it includes extra "premium" features that are closed-source. Nevertheless, none of the extra components compromises the principles outlined above.
