How can we help?

Add and refresh widgets

Touch and hold the Home Screen and choose DONNOK from the widget list. On iPhone, touch and hold the Lock Screen, then choose Customize → Lock Screen → Add Widgets. Android Lock Screen support varies by device.

In the app, open Settings → Widgets, choose a theme and display options, and save. Refresh is in the same menu. Widgets are not continuously animated; the operating system determines update timing.

Remove ads and restore purchases

In Settings → Remove Ads, check the price shown by the store and make a one-time purchase. On a new device, sign in to the App Store or Google Play account used for the purchase, then select Restore Purchases. iOS and Android purchases are separate.

If the product is missing, check your store sign-in and internet connection. Request refunds through the store where you purchased it.

Fund storage and troubleshooting

Fund records are stored on your device. Cloud backup and automatic bank connections are not provided. If something goes wrong, email support before deleting the app or resetting data.

Include your device type, operating system, app version and the screen where the issue occurred. Do not send fund amounts, account passwords or payment card numbers.

Understanding the estimates

Purchasing power and investment calculations are estimates based on economic data and assumptions, not actual balances or guaranteed returns. The app checks for Korean CPI updates when activated. If that fails, it uses valid cached data or Korean baseline data. Check the reference date shown in the app.
