Privacy Policy

At SmartDayBudget, we believe basic financial clarity should never require surrendering your personal data.

1. 100% Local Browser Calculation

All calculations, inputs, and formulas run entirely inside your own device's web browser using JavaScript. None of your financial figures, income amounts, debt balances, or budget numbers leave your machine or are ever sent to our servers.

2. No Account & No Bank Linking

We do not require sign-ups, passwords, email addresses, or bank account integrations. You can use all our tools freely and privately.

3. Local Storage Preferences

We use your browser's standard localStorage solely to remember your preferred visual theme (Light / Dark / System) and your global currency selection ($ USD, £ GBP, € EUR, etc.). You can clear this data at any time via your browser settings.
