About this app

Nulla: The Zero-Knowledge Messaging Standard

Nulla means "zero" in Latin. Zero logs. Zero tracking. Zero personal data collected. Experience the freedom of truly private communication with Nulla, the messaging app designed for those who refuse to compromise on security.

In a digital world where every click is tracked and every message is analyzed, Nulla offers a sanctuary. We don't know who you are, who you talk to, or what you say. You are not a product; you are our customer.

🛡️ CORE FEATURES

1. 100% Anonymous Registration

No phone number required.

No email address required.

No identity verification.

Simply create a unique username and start chatting. Your identity remains a mystery, even to us.

2. End-to-End Encryption (E2EE)

Your messages are encrypted on your device before they ever touch the network.

We use advanced cryptography (X25519 Key Exchange & AES).

Even if our servers were compromised, your messages would remain unreadable. Only you and the recipient hold the keys.

3. RAM-Only Architecture and Zero-Knowledge Storage

Disk persistence is completely disabled on your device. Readable versions of your messages exist only in temporary memory (RAM) while the application is open and are lost when the application closes.

On our servers, messages reside only as End-to-End Encrypted (E2EE) data blocks. The keys to decrypt this encrypted data are only held by you and the recipient on your device. No one with access to the server, including us, can view or decrypt the message content.

4. Ghost Mode đź‘»

Need absolute discretion? Hide specific chats from your main screen.

Hidden chats remain invisible—even when new messages arrive—until you manually search for them.

Perfect for maintaining privacy in physical environments.

5. Anti-Spy Protection

Nulla blocks screenshots and screen recordings at the operating system level.

Your conversations cannot be captured by spyware or curious eyes looking over your shoulder.

6. Recovery Key and Hash Verification System

Forget traditional passwords. When you register, Nulla generates a unique cryptographic Recovery Key. This key is the ONLY way to recover your account.

Security Mechanism: The raw version of your key is never stored on our servers. We only keep a One-Way Encrypted (SHA-256 Hash) and irreversible mathematical trace of the key.

When you log in, the key you enter is instantly processed through the same process, and only the match between the resulting values ​​is checked.

Warning: Because even we don't know the raw key, it's technically impossible for us to recover your account if you lose it. This is the price of true privacy.

7. Advanced Group Controls

Create public or private groups.

Admins have full control: Ban users, mute members, and restrict invites.

Global uniqueness for group names ensures your community is yours alone.

đź”’ WHY NULLA?

Most "free" messaging apps pay for their servers by selling your metadata or profiling your behavior. Nulla is a paid application because we are funded by you. This allows us to maintain an independent, secure infrastructure without selling out to advertisers.

Your Data, Your Rules.

Delete messages for everyone at any time.

Delete your entire account and wipe all traces instantly.

Block unwanted users and close your profile to search results.

Download Nulla today and reclaim your right to privacy.
