Track your expenses and income — right inside your Google account.
No server. No subscription. No third-party database. Your data stays in Google Sheets that you own.
Spendwise is a personal finance app that runs entirely on your Google account. You set it up once and use it like any web app — but everything is stored in your own Google Sheets and nothing ever leaves your Drive.
It's free, private, and yours to keep.
Expense & income tracking — Log what you spend and earn. Categorise entries, set monthly budgets per category, and see how you're doing.
Dashboard — See your monthly total, average spend per day, budget usage per category, and recent transactions at a glance.
Analytics — Compare spending across months, view category breakdowns, and spot trends with charts. Filter by week, month, quarter, half year, or full year.
Standing instructions — Add recurring expenses (rent, subscriptions, EMIs) and have them logged automatically on their due date.
Weekly email report — Get a summary of your week's spending delivered to your inbox. Shows top categories, budget alerts, income, and comparison to last week.
Full data export — Download all your expenses as a CSV file any time from Settings.
You need a Google account. That's it.

What does "Who has access" mean?
This controls who can open the web app URL — it does not share your spreadsheet data.
Option Who can open the app When to use Only myself Just your Google account Recommended. Personal use. Anyone with Google account Anyone signed into Google, but they see your data since it runs as you Only if you want to share the app with family/friends Anyone Opens without sign-in Not recommended — anyone with the URL can see your expenses In all cases the app runs as you and reads your sheets. "Only myself" is the safest choice.
Change your settings — Go to Settings in the app to set your currency, default payment method, and edit categories/budgets.
Enable weekly email reports — Go to Settings → Weekly Email Report, toggle it on, and enter your email. You'll need to grant Gmail permission once from the script editor (Run any function → Allow when prompted).
Import existing data — If you have historical expenses in CSV format, open AdminOps.gs, paste the CSV contents into the _getImportRows() function, and run importFromCSV().
Something broken? — Go to Settings → System and run STATUS (to check what's wrong) or REPAIR (to fix it). These are safe to run any time.
