Finances made for two

Duetto helps couples and households track shared expenses, split costs fairly, and stay on budget — together.

Everything you need, nothing you don't

Built for the way couples actually manage money.

Log shared and personal expenses in seconds with automatic categorization.

Anomaly detection and spending analysis powered by Claude AI.

Set budgets per category and get alerts before you overspend.

Snap a photo and AI extracts and categorizes the expense automatically.

Always know who owes what. Settle easily via Vipps or bank transfer.

Handle expenses in any currency with live conversion to your home currency.

Track spending for trips, renovations, events, and more.

Shared grocery lists and household tasks in one place.

Donut charts, progress bars, and monthly overviews to visualize your finances.

Your financial data is sensitive. Here's exactly how we protect it.

Every amount, merchant name, and note is encrypted at rest using military-grade AES-256-GCM before it ever touches the database.

Strict household-level data isolation ensures you can only ever access your own financial data — never another user's.

Versioned encryption keys allow seamless key rotation without exposing or re-encrypting existing data.

Every data modification is logged with anonymised IP tracking, giving you a complete record of all activity in your household.

All API endpoints are rate-limited per user and validated with strict schemas to prevent abuse and malformed input.
