Gugu Pinyin - Private Engine

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.

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.

Beautiful Themes
14 premium keyboard themes (free + Pro) - all keys change color instantly when you switch. Switch themes and all keys change color instantly.

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.
