Fully offline & private - no tracking, no uploads. New: 9-key T9 input, cursor mode, flow commit, clipboard history, plus 20 themes for faster typing!
Gugu Pinyin is a privacy-focused Chinese Pinyin input method powered by a self-developed local engine. It runs entirely offline with zero network access - no tracking, no data collection, no uploads.
Smart Pinyin Guidance
As you type, valid next letters are highlighted while invalid ones fade, helping you navigate the keyboard faster. Combined with phrase prediction and a large local dictionary, your typing is smooth and efficient.
Flow Commit (experimental)
Confirmed words commit automatically - no need to tap each candidate, and words commit as whole units instead of being split. Choose a Conservative / Standard / Aggressive tier; enable it in Settings, with a free trial for non-subscribers.
9-key (T9) & 26-key Layouts
Both a full 26-key QWERTY layout and a 9-key (T9) grid are supported - long-press the 中/En key to switch. T9 decoding runs entirely on-device, with full / abbreviated / mixed pinyin, syllable selection and segment-by-segment commit.
Self-developed Local Engine
All pinyin conversion, phrase matching, and prediction happen on-device. No cloud dependency means zero network latency and absolute privacy.
QWERTY + Swipe Typing
Full QWERTY layout with swipe-to-type support and dual-label keys (letters + numbers). Backspace swipe gestures for clearing or batch deleting text, and swipe down to undo a deletion.
Advanced Features (some are membership perks, with a free trial)
• Cursor mode: long-press a trigger key (G on 26-key / ' on punctuation / 5 on 9-key) and drag to move the cursor
• Clipboard history: long-press the space bar to bring up copied text and tap to insert it
• One-handed mode: shrink the keyboard to one side; swipe the space bar to switch hands
Beautiful Themes
20 premium keyboard themes (free + membership) - all keys change color instantly when you switch.
Popup System
Long-press a/e keys for punctuation popups, l key for emoji - all in an 18-cell grid layout.
Absolute Privacy
Unlike keyboards that require "Allow Full Access", Gugu Pinyin works without it. The keyboard extension has zero network capability - system-enforced isolation means your keystrokes stay on your device.

This app hasn’t received enough ratings or reviews to display an overview.
• Flow commit (experimental, 26-key): confirmed words commit automatically - no need to tap each candidate, and words commit as whole units instead of being split. Enable it in Settings and choose a Conservative / Standard / Aggressive tier; non-subscribers get a 14-day free trial
• Cursor mode is now OFF by default (enable it in Settings; non-subscribers get a 14-day free trial, unlock permanently with a subscription or one-time purchase). In the 9-key (T9) layout you can now also long-press the "5" key to enter cursor mode (previously only G on the 26-key layout and ' on the punctuation layout)
• Clipboard history: long-press the space bar to bring up text you've copied from other apps and tap to insert it (members only; upgrading users get a 3-day free trial, or unlock permanently)
• Smoother one-handed mode transition, matching the Stroke keyboard; swipe the space bar left/right to enter and switch hands
• Improved feature tips: on the first press of relevant keys (long-press G / ' / 5 for cursor mode, swipe space for one-handed mode, swipe backspace to delete / swipe down to undo) a floating hint appears; the cursor-mode tip now shows once even when the feature is off, and can be tapped to jump to Settings to enable it
• Fixed: common dictionary words (e.g. "如果") were wrongly tagged with the self-learned「学」badge — now only your own non-dictionary words get the「学」mark
• No more "keyboard height is adjustable" confirmation popup on every keyboard launch (a gentle, non-blocking hint appears once on first launch after install/update)
• Keyboard usage guide expanded: added cursor mode, flow-commit, clipboard history and one-handed mode
• Various stability and experience improvements
• Fixed: candidate bar display issue (frosted/blurred) on iOS 27
