Wengu Support

How do I sign in?

Enter your email and we send you a six-digit code — no password to remember. You can also use Sign in with Apple. Signing in with the same email (or Apple ID) on a new device restores your progress automatically.

Is my progress backed up?

Yes. Wengu works offline, and whenever you're online your review history and scheduling state sync to your account. Reinstalling the app or switching devices never loses progress — just sign in again.

A card looks wrong — a translation, pinyin, or audio issue.

Tap the flag on the card and tell us what's off. Reports go straight into our content-review queue; this is the fastest way to get a fix shipped. Wengu ships the verified December 2025 HSK syllabus, and we treat every content report seriously.

Does audio work offline?

Yes — audio downloads with your level's content so reviews work anywhere. If audio is missing, open the app while online and it will catch up in the background.

How do I delete my account?

In the app: open Profile, then Settings, and use Delete Account at the bottom of the page. This permanently removes your account and all synced data from our servers, immediately and self-service. See our Privacy Policy for details.

Something else?

Email support@wengu.co with your device model and iOS version if it's a bug — screenshots help.
