# justachat — Private Messaging Without a Phone Number

## What is justachat?

justachat (https://justa.chat) is a private, carrier-free messaging web app that lets people send real-time text messages and images to each other without ever sharing a phone number.

Instead of a phone number, every user gets a unique **JC ID** (e.g. #JC-A1B2C3). You share that ID with people you want to chat with — no phone number, no carrier, no data brokers involved.

## Key Features

- **No phone number required** — sign up with email or social login only
- **Unique JC ID system** — add contacts by their JC ID, not their phone number
- **Real-time messaging** — instant text and image messages
- **No carrier tracking** — SMS networks (AT&T, Verizon, T-Mobile) sell your texting metadata to data brokers; justachat bypasses all of that
- **No data selling** — justachat does not build ad profiles, sell user data, or share with third parties
- **Works on any device** — phone, tablet, or desktop
- **Pay-as-you-go** — simple text credit packs starting at $1.98 (no subscription required)
- **Custom pricing** — buy exactly the amount of texts you need

## Who is it for?

- People who are privacy-conscious and do not want carriers profiting from their communication metadata
- Anyone who wants to message others without exposing their real phone number
- People who have experienced carrier data breaches (T-Mobile exposed 100M+ records)
- Activists, journalists, remote workers, and everyday users who value digital privacy
- Anyone looking for a simple, clean messaging alternative to SMS

## Why it matters

Major US carriers — AT&T, Verizon, T-Mobile — have documented histories of:
- Selling location data and usage patterns to data brokers
- Sharing customer profiles with third-party advertisers
- Suffering large-scale data breaches exposing hundreds of millions of records

justachat routes messages through its own secure infrastructure, completely bypassing telecom networks. No carrier ever sees your messages or metadata.

2. Sign in (email, Google, or Apple — no phone number needed)
3. You are assigned a unique JC ID
4. Share your JC ID with friends; they add you as a contact
