For direct assistance, contact vocanumonkedi@gmail.com. Please do not send passwords, payment credentials, or other unnecessary sensitive information.

Before contacting support

  1. Close and reopen VocaNum.
  2. Confirm that VocaNum and iOS are up to date.
  3. Restart the device if the issue appears temporary.
  4. For purchase access, use the purchase-restore option available in VocaNum before purchasing again.
  5. For synchronization issues, confirm that the relevant Apple iCloud services are available on the device.

Purchases and VocaNum Pro

VocaNum Pro purchases made through the App Store are billed and managed by Apple. Subscription cancellation, billing history, and refund requests are handled through Apple’s applicable account and App Store services.

If a previously purchased entitlement is not recognized, use VocaNum’s restore-purchases option. Do not purchase the same product again solely to troubleshoot an entitlement issue unless Apple’s interface clearly indicates that a new purchase is required.

Learning data and synchronization

Core learning information may be stored locally on your device. Where optional iCloud synchronization is available, supported data may also be synchronized using Apple services. Availability can depend on device settings, Apple service status, network access, and the VocaNum version in use.

Reset, deletion, restore, and synchronization actions can change or replace learning data. Review confirmation messages carefully before using destructive data controls. VocaNum Support may not be able to recover information after deletion, device loss, corruption, or an unavailable backup.

Offline use

VocaNum is designed so that core vocabulary practice can continue without a continuous internet connection after installation. Features that rely on Apple services, purchases, synchronization, web content, or remote services may require network access.

Report a technical issue

When contacting VocaNum Support, it helps to include:

  • the VocaNum version and build number;
  • your device model and iOS version;
  • a short description of what you expected and what happened;
  • steps that reproduce the issue, if known; and
  • a screenshot only when it is useful and safe to share.

Avoid including passwords, payment-card numbers, private account credentials, or unrelated personal information in a support request.

Feature availability

VocaNum is updated over time. Screens, features, supported devices, product offerings, and troubleshooting steps may differ by version, region, subscription status, or platform availability. The current behavior shown in the app should be treated as authoritative for the version installed on your device.
