The project
Trak30 is a privacy-first budget tracker that installs like an app. Sign up without an email, snap a photo of a receipt and let it read the amount and date, automate recurring bills, and see the month as a ring of spending categories. It learns how you categorize things and flags sneaky recurring charges. The servers are paused right now; these screens come from my latest code running with demo data.
Spending ring
The month at a glance: every category around your balance.
Receipt scanning
Take a photo, and the app reads the amount and date (Tesseract OCR).
Recurring bills
Rent, insurance and utilities scheduled once, with reminders before they’re due.
Money-leak alerts
Spots small recurring charges that add up.
Calendar & analytics
Daily totals on a calendar, savings rate, runway and trends.
Smart categories
Describe a transaction and it learns where it goes next time.

Under the hood
Built with
- Node.js
- Express
- MongoDB
- Tesseract.js
- Chart.js
- PDFKit
- node-cron
- Socket.io admin
- PWA
Privacy by design: username and password only, with security questions and a one-time recovery code instead of an email. A separate real-time admin dashboard watches usage over Socket.io. Nightly jobs handle recurring bills and reminders.
