Mizan: Private Expense Tracker

Mizan is a private, offline expense tracker and money manager. No account, no sign-up, no cloud: every transaction, budget and category is stored on your device and nowhere else. It works in airplane mode, and there is no server on the other end that could be breached, sold or subpoenaed.

Most finance apps ship your transactions to a cloud you don't control, then build a profile around them. Mizan can't, because there's nothing on the other end.

PRIVATE AI THAT RUNS ON YOUR PHONE
Mizan can run an AI assistant fully on-device: no API key, no internet, no cloud. Ask about your spending and get answers from a model that never sends a byte off your phone. Choose the model size that fits your phone's memory.

YOUR BACKUPS, YOUR KEYS
Backups are encrypted on your device with AES-256-GCM, keyed from your passphrase via PBKDF2-SHA256 over 600,000 iterations. You decide where the encrypted file goes. Lose the passphrase and not even we can recover it: there is no "we" holding a copy. That's the point.

MIZAN PREMIUM
Unlocks the on-device AI, the bring-your-own-key cloud assistant, unlimited categories/budgets/recurring/accounts, receipt attachments, the home-screen widget, and more.
Monthly $3.99 | Yearly $19.99 | Lifetime $49.99 once. (USD, may vary by region. Subscriptions renew until cancelled; Lifetime never charges again.)

BRING YOUR OWN AI KEY (also included)
Prefer a cloud model? Route it straight from your phone to any provider you trust: OpenAI, Anthropic, Gemini, Groq, OpenRouter, DeepSeek, or self-hosted Ollama. We never proxy requests or see your keys. A "What gets sent" card shows the exact payload before anything leaves your phone.

HONEST ABOUT WHAT MIZAN ISN'T
- No automatic bank linking: you add entries or import CSV
- No silent cloud sync
- No investment advice

Money you can measure, privacy you don't have to think about. That's Mizan.
