Frequently Requested Support Guidance
1. How do I restore In-App Purchases or Subscriptions?
In any of our mobile applications, open the Settings or Profile screen and tap “Restore Purchases.” Ensure you are logged into the same Apple ID or Google Play account used during the initial purchase. The system communicates directly with Apple StoreKit or Google Play Billing to validate your receipt.
2. How do I request account deletion or data removal?
You can delete your account directly inside any of our mobile apps under Settings → Account → Delete Account. Alternatively, you can visit our web-based deletion request portal at quangminhtri.com/account-deletion/ or email our support desk at support@quangminhtri.com.
3. How do I report a technical bug or crash?
Please email support@quangminhtri.com with: (1) The application name and version, (2) Your device model and operating system version, and (3) Steps to reproduce the error or relevant screenshots. Our engineering team logs and addresses all tickets systematically.
