Self-hosted · Zero-knowledge
Everything about your credit cards. Except the money.
A control panel for the cards you actually have - which one to use, what’s due, what’s expiring - without ever handing your bank details to a server you don’t own.
How it works
Zero-knowledge
Encrypted before it leaves your device
Card numbers, balances, merchant names - encrypted client-side with AES-256-GCM before the server ever sees them. A compromised server exposes metadata, never the numbers.
Routing engine
Which card, right now
Type a merchant and an amount. Get a ranked answer with the actual math - rate, offer, milestone proximity, surcharge - not a guess.
Self-hosted
Runs on your own box
No SaaS, no data broker, no "we value your privacy" banner. Docker Compose, your Postgres, your domain.
