Help for VietQuest: Learn Vietnamese on iPhone and Android.
Questions, problems or feedback? Email us and we will get back to you as soon as we can:
To help us solve a problem faster, please include your device model, your iOS or Android version, the app version (shown in Settings), and a short description of what happened.
You can also send feedback from inside the app using the Feedback form.
Subscriptions are managed by Apple (iPhone, iPad) or Google (Android), not by us.
Cancel at least 24 hours before the end of the current period to avoid being charged for the next one. Deleting the app or your VietQuest account does not cancel a subscription.
Premium is tied to your VietQuest account. Sign in to the same account you used to buy it, then open the Premium screen and tap Restore purchases. Premium comes back automatically once you are signed in with that account. If you still do not see it, email us at the address above and include the account email you used.
All purchases are processed by Apple (iPhone, iPad) or Google (Android), and we cannot issue refunds ourselves. Please request a refund directly from them: for App Store purchases, go to reportaproblem.apple.com; for Google Play purchases, request it through Google Play.
In the app, go to Settings > Delete account. If you have uninstalled the app or cannot sign in, see Asking Us to Delete Your Data Without the App in our Privacy Policy, or email us at the address above with the subject "Delete my VietQuest data".
Syncing progress across devices is a Premium feature and requires signing in to the same account on each device. If something still looks wrong, email us with the details above.
Check that VietQuest has permission to use the microphone (and speech recognition on iPhone) in your device Settings, then reopen the app.
