Support

For app issues, feedback, purchase-delivery questions, or privacy requests, email lzbgt@icloud.com.

Include: app version, iOS version, the visible error or request ID, and the action that led to it. Never send an API key, identity token, payment-card details, or an entire private conversation.

Documents or translation

Confirm the document's learning and explanation languages. Scanned PDFs may take longer because OCR runs first. Apple translation requires the relevant system language resources.

Generated articles or redeem codes

Article generation requires a signed-in LangLearn Cloud account, a supported language pair, and available cloud time. A no-charge six-digit support code can be used only in the independent Apple-authenticated web portal, once before its expiry; an invalid, expired, or already-used code intentionally shows the same error. Never include a code in a support message.

Speech quality or playback

Select an installed Apple premium/enhanced voice or an Aliyun voice compatible with the chosen language. Cloud speech may fall back only when the app shows that status; it never silently changes provider.

Assistant connection

Check that the selected provider is configured, microphone access is allowed, and the phone has network access. Personal Aliyun uses your own account and key. LangLearn Cloud requires Sign in with Apple and available cloud time.

Purchase delivery

In LangLearn Cloud account settings, tap Retry Pending Purchases, then refresh the account. The app intentionally leaves an Apple transaction unfinished until the server has safely delivered credit. For App Store billing or refund decisions, use Apple's purchase support. For a PayPal web purchase, include the PayPal order ID in your email.

Account deletion

Open Assistant provider settings → LangLearn Cloud → Delete Account. The app will require fresh Sign in with Apple authentication. If this flow cannot complete, contact support from the Apple account associated with the LangLearn account.
