Frequently Asked Questions
Is my financial data stored on a server?
No. All expense data is stored exclusively in your browser's localStorage. Nothing is uploaded to any server. Your financial information never leaves your device, making this one of the most private expense tracking options available online.
Will I lose my data if I clear my browser cache?
Yes, clearing browser data or localStorage will remove your saved expenses. To keep a backup, use the CSV export button regularly to download your transaction history. You can re-import that CSV into any spreadsheet app if needed.
Can I use this expense tracker on my phone?
Yes, the tool is fully responsive and works on mobile browsers. The layout adapts to smaller screens with single-column forms and a stacked chart view. You can add it to your home screen for quick access without installing an app.
How do I export my expenses for tax purposes?
Click the CSV button in the controls bar. This downloads a file containing date, description, category, and amount for every transaction matching your current filters. Open it in Excel or Google Sheets to sort, sum by category, or attach to your tax filing.
Is there a limit to how many expenses I can track?
There is no artificial limit. localStorage typically allows 5-10 MB of data per site, which can hold thousands of expense entries. For most users tracking daily expenses, this is more than enough for several years of data.
