Your financial outlook.
Secure. Local. Accessible.

Every finance app monetizes your transactions. We built the opposite — track spending, find forgotten subscriptions, catch unusual charges, all from your machine. No cloud. No tracking.

You are not the product.

What you get

See the full picture. Keep full control.

Everything runs on your machine. Every feature works offline. Your financial data never touches someone else's server.

Web dashboard at localhost

Cash flow, spending breakdown, subscription commitments, alerts, and 6-month trends — all in a local web UI. Click into any number to drill down.

Find forgotten subscriptions

150+ services recognized instantly. Pattern detection catches the rest from 3+ recurring charges. Know exactly what you're paying for.

Catch unusual charges

Duplicate charges, price increases, bundle overlap (Disney+/Hulu/ESPN+ stacking). Problems surfaced before they grow.

See where every dollar goes

Auto-categorized transactions with 3-month rolling averages. Outlier badges flag unusual months so you spot problems early.

Security model

Your data never leaves your machine.

We eliminate entire threat categories by design. Where we handle sensitive data, we delegate to proven, audited tools — not homebrew crypto. Every layer is something you can independently verify.

What we don't do

  • Cloud storage
  • Remote API calls
  • User accounts or login tokens
  • Session cookies
  • Telemetry or analytics
  • Phone home — ever

What we delegate

  • Credentials → OS keyring
  • Backup encryption → age (ChaCha20-Poly1305)
  • Disk encryption → BitLocker / FileVault / LUKS
  • TLS → Python cryptography library
  • We didn't build our own — that's the point
Data retention policy, 675 transactions tracked, and sync history showing append-only audit trail

Full audit trail. Every sync logged. Append-only by design.

Full security posture → TLS certs, CSP headers, rate limiting, file permissions, data integrity — all documented in source
