How can we help?

It works like a real-time voice call. Once you allow microphone and call permissions, your AI tutor picks up and carries on a natural conversation in the language you're learning. After the call, you can review corrections and translations sentence by sentence.

iOS 16 or later, and Android 9 or later.

Subscriptions are managed through the store you subscribed through.
iPhone: Settings → Apple ID → Subscriptions → AllLang
Android: Google Play → Profile → Payments & subscriptions → Subscriptions
The AllLang app itself can't cancel a subscription directly — please use one of the paths above.

Payments go through the App Store / Google Play, so refunds follow each store's policy. For the App Store, request one at reportaproblem.apple.com; for Google Play, you can request a refund from your order history in the Play Store.

Because iOS calls run through CallKit, there can be a brief silent moment right when a call starts. If it's still silent after 1–2 seconds:
1. Check that the side silent switch (orange) is off.
2. Make sure no other calling app is active, and close it if it is.
3. If it still doesn't work, fully quit the app and relaunch it.

Yes — you can currently learn English, Japanese, French, Spanish, Chinese, and German, and you can switch your learning language anytime in the app settings. We're continuing to add more languages.

You can delete it directly from Profile → Settings → Account → Delete account in the app. Deleting permanently erases your learning history, saved words, and call history. If you need help, contact support@alllang.app.

Call audio isn't stored after it's processed — only the text transcript is encrypted and saved as part of your learning history. See our Privacy Policy for details.
