dereknguyen269/simple-fam-fin ? reverse-engineered prompt

Build me a simple family finance app that helps my household track money in one place, with a clean dashboard for income, expenses, budgets, savings goals, and recurring bills. I want to be able to add transactions with categories and tags, manage multiple wallets or accounts, and see charts that make it easy to understand where the money is going.

It should feel privacy first, so data is stored locally by default, with an optional Google Sheets sync or backup for sharing across devices. Please include family sharing so more than one person can use it, and make the interface responsive so it works well on desktop and mobile. I’d also like it to support multiple languages and look polished and modern.

If you need to check current setup details or best practices, look up the latest docs online.
