## What is Nullchat?

NullChat is a privacy-focused messaging app designed for secure communication without exposing your identity.

Instead of phone numbers, users connect using anonymous cryptographic IDs. Messages are protected with end-to-end encryption and the server never has access to your private keys.

Key features:
• End-to-end encrypted messaging
• Anonymous identity (no phone number required)
• Local encryption keys that never leave your device
• Biometric unlock with Face ID or fingerprint
• Screen protection against screenshots and recording
• Privacy screen when the app is in background
• Optional 2FA (TOTP) for additional security
• Report and block users directly within the app

NullChat was built with a privacy-first architecture where cryptographic operations happen locally on the device. The goal is simple: give users full control over their communication without unnecessary data collection.

NullChat is intended for users 18 years of age and older.

By using NullChat, you agree to our Terms of Service and Privacy Policy. There is zero tolerance for objectionable content, harassment, or abusive behavior. Violations will result in immediate account removal.
