DONNOK - My Money Display

Your balance stays the same. Its value changes. DONNOK displays the estimated purchasing power of funds you enter. • Record your funds Add cash, deposits, savings and money owed to you. Enter deposits after subtracting any loan amount. No account or bank connection is required. • Purchasing power based on Korean CPI Estimates use the starting date of each fund and South Korea's Consumer Price Index (CPI). The app checks whether economic data needs updating at launch and when returning to the foreground. Offline, it uses valid cached data or bundled Korean data. Data updates do not change your original amount or starting date. • Understand the data Check observation periods, sources, frequency, missing values and data status. Global annual CPI comparisons are separate from personal purchasing-power displays. Government debt-to-GDP ratios are distinct from South Korea's D1 national debt amount. This release uses South Korea as the CPI reference for personal displays. • Eight display themes Choose MINIMAL, MONO, FLIP, LED, NIXIE, SEOUL, NYC or BANK and enjoy a full-screen display. Explore data-based estimates for Korean M2 and D1 national debt, or simulate investment growth using an assumed return. • Home screen widget Choose a theme and configure decimal places, cumulative change and calculation-time labels. Widget values follow the app's economic-data and calculation policies. Android determines when widgets refresh. • Stored on your device Manage KRW, USD and JPY funds separately. Korean and English are supported. Changing currency does not convert your funds or change the CPI reference country. Personal fund names and amounts are not sent to the economic-data API. • Optional ad removal The app includes banner ads. A one-time purchase removes ads; purchasing and restoring depend on store availability. Fund records and calculations are available without a purchase. • Optional usage analytics Usage analytics is off by default. If you opt in, Google Analytics collects basic app usage, such as launches, usage time and screen visits, with an app-instance identifier. Fund names, amounts and calculation results are not collected. Change your choice in Settings > Privacy. Please note Displayed values are estimates based on economic data and calculation assumptions. They do not represent actual bank balances or guarantee investment returns. Daily values between monthly CPI observations use logarithmic interpolation. Estimates beyond the latest observation are limited to the app's projection period; after that, the last valid value and an update-needed notice are shown. M2 and D1 national debt follow separate estimation policies. These estimates and simulations are informational and are not financial advice.
