🏳️ Base Currency per File
Every tracker file has a base currency (default AUD). All amounts in the file are in that currency. Set it via the file chip long-press → Base currency — e.g. a EUR account file for a European bank account alongside your AUD expenses.
🧾 Per-Entry Currencies
Receipts, income entries, subscription entries, and ongoing entries can each record the currency they were actually billed in, even when it differs from the file's base — useful for overseas purchases and foreign-currency subscriptions.
Expenses, budgets, accounts, assets, and depreciation files are single-currency: all amounts are in the file's base currency, and the app blocks moving records between files with different currencies.
🔄 Converting When Linking
When a link would carry an amount into a file with a different currency (e.g. creating an expense from a USD receipt into an AUD expense file), a conversion dialog offers three choices:
- Copy as-is — applies your stored exchange rate for that pair (or 1:1 if none)
- Enter manually — type the converted amount or rate yourself
- Convert with Gemini — asks the AI for an approximate historical rate for the transaction date (requires an API key, see AI features)
📊 Exchange Rate Table
System Settings → Currency → Exchange rates holds your default rates. Each row has a currency pair, the rate, and the date it applies from — so you can keep historical rates side by side. The reverse direction is derived automatically; you never need to enter both.
🚩 FX Review Flags
Records created through a cross-currency link are flagged with their source currency. The flag marks amounts that came from a conversion, so you can revisit them once you know the exact rate (e.g. the one your bank actually charged) and correct the amount.
