About Expentify
Modern Personal Ledger Architecture & Financial Literacy Hub
Expentify is a free personal bookkeeping app built on double-entry accounting, for individuals, households and freelancers who want an accurate record of their cash, bank balances, cards and spending, with optional AI-assisted insights.
It was built by Nasim Farhan to bring cash, bank accounts, cards and shared costs into one ledger that always balances.
Double-Entry Precision
Every entry is recorded on both sides, so cash, bank balances, card debt and spending categories always reconcile.
AI-Powered Insights
An optional Google Gemini analysis reviews your spending on request and suggests where to look more closely.
Zero Data Selling
Your financial ledgers belong solely to you. We never sell, rent, or monetize your transactional records or personal data to third-party brokers.
Technology & Cloud Infrastructure
How Expentify is built:
React, TypeScript and Tailwind CSS on the web; the same app packaged for Android with Capacitor.
A Node.js (Express) server for the website and AI features, with Google Firebase for sign-in and data storage.
Who Writes These Guides
Expentify's Finance Academy guides are written by Nasim Farhan, the developer of this app — not by a team of financial engineers or credentialed advisors. The guides reflect a builder's-eye view of personal bookkeeping: how the underlying accounting mechanics actually work, and why they were implemented the way they are in this specific tool. They aren't a substitute for advice from a licensed financial advisor, accountant, or tax professional, and we'd rather say that plainly than imply a credential we don't have.
