My Finances

A local, private desktop app to review and manage personal finances on macOS. One button fetches current account balances from Akahu (a New Zealand open-banking aggregator), stores them in a local SQLite database, and shows summaries plus per-account history graphs.

Why

Banks and accounting apps show your money scattered across dozens of screens and logins. This app pulls every NZD account you've connected to Akahu into one view: a dashboard of cards with current balances, all-time-high badges, sub-totals for assets and liabilities, and a line chart of each account's history. Your data never leaves your machine (except the one fetch from Akahu) and never touches a third-party server.

Features

• One-click balance refresh — fetches live balances from all your Akahu accounts and stores them once per day.
• Dashboard — a card per account showing current balance and 30/180/360-day change chips, plus virtual "Total", "Assets & Savings", and "Liabilities" sub-total cards.
• All-time-high badge (⭐) — a card earns a star when its latest balance equals its all-time maximum.
• Per-account history — click any card for a line chart of the account over time, with current, min, and max values.
• Accounts config — hide accounts you don't care about (they're excluded from totals too), and add manual accounts (property, cash, etc.) with hand-entered values.
• Settings — store your Akahu credentials in the macOS keychain, and toggle automatic fetch on app launch.
• iCloud sync (multi-machine) — the database can live in iCloud Drive so the same dataset is available across your Macs, with lossless conflict merging when two machines write while apart.

Currency: only NZD accounts are stored; non-NZD accounts are silently ignored.

Tech stack

• Frontend: Vite 7, React 19, TypeScript, recharts, React Router v7
• Desktop shell: Tauri v2
• Storage: SQLite via rusqlite
• HTTP: reqwest for Akahu calls
• Secrets: macOS keychain via keyring (falls back to env vars AKAHU_APP_ID / AKAHU_USER_TOKEN)

Prerequisites

• macOS (Apple Silicon or Intel)
• Node.js 20+ and npm
• Rust (stable)
• An Akahu account with at least one bank connection, plus an app ID and user token (create them in the Akahu developer dashboard and paste them into the app's Settings screen, or set the env vars above).

Build & run

npm install            # first time only
npm run tauri dev      # dev mode (hot reload, opens a window)
npm run tauri build    # production build -> My Finances.app

The built app lands at src-tauri/target/release/bundle/macos/My Finances.app.

Where your data lives

• By default: ~/Library/Application Support/my_finances.db
• If iCloud Drive is available, the database is stored in ~/Library/Mobile Documents/com~apple~CloudDocs/my_finances/my_finances.db so it syncs across your Macs. The first launch copies any existing local database into iCloud once (the old local copy is kept as a backup).

Inspect the database directly with:

sqlite3 ~/Library/Application\ Support/my_finances.db
# or, if using iCloud:
sqlite3 ~/Library/Mobile\ Documents/com~apple~CloudDocs/my_finances/my_finances.db
