The free, self-hosted personal finance app that keeps your data private.
Open source. Self-hosted. No bank connection required. Built for people who take data privacy seriously.
Most budgeting apps require access to your bank account. YAFFA doesn't. Your financial data stays on your server, not someone else's cloud.
A powerful, easy-to-use expense tracker
YAFFA empowers your financial freedom, offering intuitive transaction management, analytical and forecasting capabilities.
