Drop your bank CSV — get instant spending analysis.
Everything runs in your browser. Nothing leaves your device.
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.
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.
Perfect for privacy-conscious individuals, freelancers tracking business expenses, or anyone who wants a quick, non-committal way to audit their spending without syncing their bank login to a 3rd-party cloud.

Managing your money shouldn't mean sacrificing your privacy. Financial Expense Analyzer (Spendly) is designed for security-conscious individuals who want the power of a financial dashboard without the risk of cloud-based data harvesting. Whether you are analyzing personal spending, preparing business reports, or tracking a shared budget, Spendly processes everything 100% locally.
Our tool handles raw CSV files from major banks like Chase, MUFG, Revolut, and more. It uses advanced client-side JavaScript to parse, sanitize, and categorize your transaction history. The interactive charts, powered by Chart.js, allow you to see monthly spend trends, category distributions, and smart insights into your largest spending leaks.
By utilizing a local-first architecture, Spendly is inherently compliant with strict data protection standards. Since no data is transmitted over the network, your financial secrets remain your own. It's an "air-gapped" experience for the web age.
