PRIVACY BY DEFAULT β All accounts, transactions, categories, and budgets are stored only locally on your device. β No server-side component and no analytics β your financial data is not sent anywhere. β The only network request is an anonymous retrieval of exchange rates, during which only currency codes are transmitted. MULTICURRENCY β Keep accounts in different currencies simultaneously. β Automatic conversion and overall balance at current exchange rates. β The ability to manually set your own rate. β Rates are cached, so the app works completely offline.
