Appendix B — Technology Stack

Overview

This appendix is for IT-minded readers. Most users can safely skip it. Church Genius Pro is built on a modern, secure, and scalable technology stack.

Backend

• Spring Boot — the application framework that handles all the server-side logic.
• Spring Security — authentication, session management, and access control.
• Hibernate / JPA — how the application talks to the database.
• PostgreSQL — the database where all your church's data is stored. (MySQL is also supported.)

Frontend

• Modern HTML, CSS, and JavaScript with progressive enhancement.
• Responsive design — works on phones, tablets, and desktops without a separate app.
• Optional native-feel installation through "Add to Home Screen" (PWA).

Integrations

• Stripe — for online donations, event payments, and recurring giving.
• Email and SMS services — for transactional emails, reminders, and notifications.
• QR Code generation — for event check-in, kids ministry pickup codes, and public screen links.
• PDF / Excel reporting — for tax statements, financial reports, and member exports.

Security

• Role-based access control — only authorised users see sensitive data.
• Encrypted session cookies and automatic timeout after 30 minutes of inactivity.
• Database backups on a configurable schedule, optionally to cloud storage.
• Stripe handles all card data — Church Genius Pro never stores credit card numbers.

Scalability

The platform supports churches of all sizes, from house churches to multi-campus mega-churches with tens of thousands of members. Multi-tenancy keeps each church's data isolated.
