MONEY.

Drop your bank CSV — get instant spending analysis.
Everything runs in your browser. Nothing leaves your device.

What can you do?

SPENDLY transforms raw, messy bank CSV exports into beautiful, interactive financial dashboards. It automatically categorizes transactions, visualizes monthly trends, and highlights spending leaks—all without any server-side processing.

Privacy First

Unlike other budgeting apps, we never see your data. Your financial history is processed strictly in your browser's memory. No account creation, no email harvesting, and zero tracking. Your money, your privacy.

Best For

FREQUENTLY ASKED QUESTIONS

Is my financial data safe?
Absolutely. Your CSV file is parsed locally in your browser. We never upload your data to our servers, and we don't even have a database to store it.
Does it support my bank?
We support any CSV file that contains at least a "Date" and an "Amount" column. You can manually map your bank's specific column names during the upload process.
Why is this better than Mint or YNAB?
Unlike cloud services, we don't require your bank login credentials or a subscription. It's a "one-off" analysis tool for people who value privacy above all else.
Can I use it offline?
Yes. Once the page is loaded, you can disconnect from the internet and the tool will continue to work perfectly, as all logic is client-side.
