Common questions
Do I have to enter my income?+
No, income is optional. Without it you'll still see your total expenses and category breakdown — add it to also see your remaining balance and savings rate.
Which currencies can I use?+
You can switch between $, €, £, ₹, ₨, and ¥. This only changes the symbol shown — it doesn't convert between currencies.
Can I download my results?+
Yes — "Download summary as image" exports your income, total expenses, remaining balance, and category breakdown as a PNG you can save or share.
How is my remaining balance calculated?+
It's your monthly income minus the sum of every expense amount you've entered, shown in green when positive and red when you're over budget.
Is my financial data stored anywhere?+
No. Every calculation happens in your browser — nothing you enter is uploaded, saved, or sent to a server.
