Support

Email: tikki.dinh@gmail.com · We usually reply within 2 business days.

When you write, tell us your phone model, iOS or Android version, App version (Profile → bottom of the screen) and, if it is about Plus or invites, your support ID (Profile → Support ID → Share support ID). Do not send us your financial figures or passwords.

Common questions

Where is my data stored? Your financial data is stored only on your phone. We have no account system. Our small server holds only invite codes, invite rewards and free Plus grants, linked to a random support ID, never your financial data. See the Privacy Policy.

I lost my phone or deleted the App. Can you restore my data? No, because we never receive it. If you had a device backup (iCloud or a computer backup), restoring your phone from it may bring the data back.

How do I delete my data? Open Profile → Delete all data. Deleting the App also removes its data from the phone.

What is my support ID? A random ID that the App creates on your phone (for example vung_3f9a…). It is not linked to your name, phone number or Apple ID. Find it in Profile → Support ID. We need it to look up your invites or give you free Plus.

How do invites work? Open Profile → Invite friends and share your code. When a friend installs Vung on their own iPhone, finishes setup and enters your code, you get 30 days of Vung Plus free (up to 12 months a year). Codes work only in the real App on a real iPhone. The full rules are in the Terms of Use.

My friend used my code but I did not get Plus. Open the App again; rewards appear on the Overview screen. If nothing happens within a day, email us your support ID.

How do I delete the data on your server? Email us your support ID, ideally before you use “Delete all data” (which creates a new ID). We delete your invite records, codes and free Plus grants within one month.

How do I cancel my subscription? iPhone: Settings → your name → Subscriptions → Vung. Android: Google Play → Payments & subscriptions → Subscriptions. Deleting the App does not cancel it.

I bought Plus but it is not active. Open Profile → Restore purchases while signed in to the same Apple ID or Google account you bought with.

How do I get a refund? Apple: reportaproblem.apple.com. Google: Google Play help. Refunds are decided by Apple or Google.

How do I change my ad choices? Profile → Privacy and ads choices. Vung Plus removes all ads.

Notifications do not arrive. Check that notifications are allowed for the App in your phone settings and that Focus or Do Not Disturb is not blocking them. Reminders are scheduled on your phone for the time you chose in Profile (default 8:00).

Is the score financial advice? No. It is a guide based on the numbers you entered. See the Terms of Use.
