developer-akbar/finance-manager-mobile-app-v2 ? reverse-engineered prompt

Build me a premium dark themed personal finance app called FinMan.

I want it to work on Android and in the browser, and all data should stay on the device with no accounts or cloud sync. The app should let me track income, expenses, and transfers, organize everything by accounts and categories, and show simple charts and summaries so I can understand my money at a glance.

Please include a dashboard with net worth, savings rate, spending insights, and a tip of the day. I also want search across transactions, notes, categories, and accounts, plus budget tracking with progress indicators. It should support importing Money Manager Excel or CSV files, and exporting transactions too.

Add a PIN lock for privacy, settings for account groups and categories, and make the whole thing feel polished and modern with a strong dark UI. If you need to check any current docs for the mobile or chart libraries, go ahead and look them up online.
