How I built a secure personal financial vault for under $0

*Meet *BUDGET-FLOW: A personal financial command center that puts security first.

🛠 The Tech Stack
Framework: Python + Streamlit (for the rapid, clean UI)

Data Storage: Google Sheets (acting as a free, reliable cloud database)

Deployment: Hosted on Streamlit Community Cloud

Security: Built-in authentication gate to keep financial data private

💡 Why I built it
Most apps lock your data away or bombard you with ads. I wanted to focus on:

Privacy: The data lives in my private Google Sheet, not a third-party corporate server.

Control: I can reset, edit, and analyze my spending habits exactly how I want.

Zero Cost: By leveraging Streamlit Cloud and free tiers, the entire infrastructure costs $0/month.

I am still iterating on the features (like analytics and custom cycles). If you're a developer, I'd love for you to take a look at the code or try to "break" the login security!

GitHub Repository: [GitHub]

I’m looking forward to your feedback on the architecture and how I can improve the user experience.
