Your income, expenses, and purchase history are among your most sensitive personal data—they reveal everything about your life. Yet most budgeting apps store this data in the cloud, analyze it, and sometimes share it with third parties. Data breaches, advertising exploitation, government and corporate surveillance—are you truly protected from these threats?

What we need:

• End-to-end encryption — designed so even developers can't read your data
• Local-first data storage — kept only on your device
• Zero tracking — no ads, no data selling
• Open source — transparent, auditable code

Financial autonomy is a fundamental human right. Let's create a budgeting app that keeps your financial data yours alone. It's time for a choice that doesn't compromise on privacy.
