Money Tracker
Keeping track of money usually means signing up for an app and handing over your data. Money Tracker takes the opposite approach: it’s a single HTML file, and everything runs and stays in your browser.
A personal finance dashboard that lives in a single HTML file. It tracks income and expenses, charts where the money goes, locks behind a PIN, and asks Google Gemini for plain-language insights — all without a server or an account.
