    HOW TO

    How to use

    1. Choose Expense or Income, enter the amount, pick a category, date and payment method, and press Add.
    2. Check Repeat monthly for rent, subscriptions or a paycheck so it's added on the same day every month.
    3. Set a monthly budget to see what's left and how much you can spend per day for the rest of the month.
    4. Click a day on the calendar to see its entries, compare categories in the donut chart, and export a month or everything as CSV.

    FAQ

    FAQ

    Where is my data stored?

    Only in this browser's local storage. Nothing is uploaded, and clearing site data erases it, so download a Backup file from time to time.

    Can I open the CSV in Excel or Google Sheets?

    Yes. The CSV is UTF-8 encoded with date, type, category, amount, payment method, note and recurring columns.

    How do I stop a recurring item?

    Click it in the list. Skip this month removes it for that month only, while Delete recurring removes it from every month.
