What is Expense Tracker?

A personal expense tracker that helps you monitor daily spending by category. Add expenses with amounts, categories, and dates, then visualize your spending patterns with interactive charts to identify where your money goes.

Every entry is saved to your local device — nothing leaves your device, nothing ends up in someone's database. Nine built-in categories (food, transport, housing, utilities, health, education, shopping, entertainment, other) cover most spending. Two charts show the breakdown: a pie for category share, a bar series for spending over time. CSV export gives you a clean file for spreadsheets or your accountant.

How to use

1. Step 1 — Add an expense by entering the amount, selecting a category (food, transport, entertainment, etc.), and optionally adding a note.
2. Step 2 — View your spending breakdown by category in the pie chart, or track spending over time in the bar chart.
3. Step 3 — Export your expense data as CSV for use in spreadsheets, or clear entries to start a new tracking period.

When to use

• Tracking a single trip's spending without installing a finance app.
• Running a monthly budget check to see which category quietly eats your paycheck.
• Logging shared household costs you'll split with a flatmate at month end.

Result

Track a week of spending: 45 on groceries Monday, 12 lunch Tuesday, 30 on fuel Wednesday. The pie chart instantly shows food is roughly two-thirds of your spending — in whichever currency you picked.

FAQ

Where are my expenses stored — does this send data to a server?

Everything is saved to your device's local storage. The tool never uploads expenses anywhere. If you clear your saved site data or use a different device, the entries won't be there — back up via CSV export.

Can I track expenses in different currencies?

Pick your currency from the dropdown in the header — the symbol updates everywhere, but amounts aren't converted between currencies. If you mix currencies, either convert before entering or run separate tracking periods, one per currency.

How do I get my data into Excel or Google Sheets?

Use the Export button to download a CSV file with columns for date, category, amount and note. Both Excel and Google Sheets open CSV directly — no special import step.

What happens if I clear my saved site data?

Clearing site data wipes the expense list, since storage lives on your device. Before clearing that data or moving to a new device, export to CSV — that file is portable and survives anything.

Can I edit an expense after adding it?

Yes. Hover any row and click the pencil to fix the amount, category, date or note in place — no need to delete and re-add. You can also search by note or category and set a From/To date range to narrow the list and charts to a single week or month.
