Kino

A local-first personal finance desktop app built with Go, Vue 3, and Wails.

Features

• Multi-account tracking — checking, savings, credit cards, investments, loans, crypto, cash
• Transaction management — create, edit, categorize, reconcile, and filter transactions
• Import — CSV and OFX/QFX file import with exact and fuzzy duplicate detection
• Budgets — monthly, weekly, and annual budgets with optional rollover
• Cash flow — Sankey diagram showing income sources flowing to expense categories
• Net worth — 12 or 24-month history snapshots
• Goals — savings goal tracking linked to accounts
• Local data — all data lives in a single .kino SQLite file you own and control

Privacy

No accounts, no sync servers, no telemetry. Your .kino file can be stored anywhere — iCloud Drive, Dropbox, Google Drive, OneDrive, or just your local disk.

Development

Prerequisites: Go 1.24+, Node 18+, Wails v2

# Install Wails CLI
go install github.com/wailsapp/wails/v2/cmd/wails@latest

# Live development (hot reload)
wails dev

# Production build
wails build

The dev server also exposes a browser UI at http://localhost:34115 with access to all Go methods via devtools.

Architecture

Layer	Technology
Desktop shell	Wails v2
Backend	Go
Frontend	Vue 3 + TypeScript + Vite + Tailwind CSS
Database	SQLite (WAL mode, via modernc.org/sqlite)
Charts	Chart.js

Backend modules:

File	Responsibility
app.go	DB lifecycle, file open/create/move, MRU tracking
app_accounts.go	Account CRUD
app_transactions.go	Transaction CRUD, filters, transfer pairs
app_categories.go	Category CRUD (hierarchical)
app_budgets.go	Budget CRUD with rollover logic
app_cashflow.go	Sankey diagram data
app_networth.go	Net worth history snapshots
app_summary.go	Monthly aggregation (income, expenses, savings)
app_import.go	CSV/OFX import, duplicate detection
internal/db/	SQLite connection, schema migrations, all queries
internal/models/	Shared data types
internal/importer/	CSV and OFX parsers

Key conventions:

• All monetary values are stored as int64 cents (no floating-point)
• Transfer transactions are linked in pairs via TransferPairID
• Schema migrations are idempotent and version-gated via kino_meta
• The frontend calls Go methods directly via Wails RPC bindings
