User Agreement

Last updated: July 25, 2026. By using MouthFu, you agree to learn Chinese with dignity optional.

Use of the app

MouthFu provides humorous Chinese phrase-learning content, audio, phonetic hints, and shareable cards. It is for casual learning and entertainment, not certified translation, legal advice, medical advice, or formal language testing.

Purchases

MouthFu may offer a one-time non-consumable in-app purchase to unlock additional phrases and future phrase updates. Payments, transaction verification, restoration, and refund requests are handled by Apple through StoreKit and the App Store.

Content

The app uses jokes and playful phrasing. Please use shared cards responsibly. Do not use MouthFu content to harass, impersonate, defame, or make the internet worse in the boring legal way.

Availability

We may update, add, remove, or change content and features. We try to keep the app useful and funny, but we cannot promise that every mouth cheat will survive every accent, dialect, or sleepy Tuesday.
