LatteChat --- Under Development

Overview

This project is a privacy-first social platform backend where users can only interact after mutual QR-based connection approval.

Unlike traditional apps, no one can directly message, react, or interact unless a connection is explicitly established.

Core Concept

• Users register via OTP authentication

• Contacts are synced, but:

  • ❌ No chat
  • ❌ No interaction

• Interaction is only enabled after a QR-based connection handshake

Connection Flow

1. User-A scans User-B’s QR code

2. User-B gets:

   • ✅ Accept
   • ❌ Reject

3. If accepted:

   • Connection is established (persistent)

4. If removed/blocked:

   • Must reconnect via QR again

QR System Rules

Individual QR

• • Valid for 1 minute
• • One-time use only
• • Only 1 active request at a time

👥 Group QR

• ⏱️ Valid for 1 hour
• ♾️ Unlimited joins during validity
• Managed by Admin

Status / Posts

• Users can share status:

  • 👥 Connected users → can like, comment
  • 🌍 Public users → view only (no interaction)

• Restrictions:

  • • No share
  • • No screenshot (client-level restriction)

Philosophy

• Privacy-first
• Intentional connections only
• No random DMs / spam
• Controlled social interaction

Current Progress

• Initial backend setup
• Basic server configuration
• User model (MongoDB + Mongoose)

Tech Stack

• Node.js
• Express.js
• MongoDB (Mongoose)

Upcoming

• • OTP Authentication flow
• • Contact sync logic
• • QR generation & validation system
• • Connection-based messaging
• • Status system

Note

This is an early-stage backend. Core architecture is being designed with scalability and strict privacy controls in mind.
