Welcome to Nulla

Communication without profiles or names.

How to use service

Copy your identifier and share it with others to receive contact requests. Accept requests to start encrypted conversations.

How we protect you

We use an authenticated Diffie–Hellman key exchange to establish fully encrypted sessions. Only you and your contact can read each other's messages.

About the account seed

Your presence in Nulla originates from a single cryptographic seed. It defines your identity. The seed exists only on your device.

Your contact string

Share your identifier with others so they can send you contact requests. Your identifier is unique to your account and allows others to find and contact you.

Add contact

Enter someone's contact string to send them a contact request. Once they accept your request, you can start an end-to-end encrypted conversation.

Account settings

Export your account to back it up or transfer it to another device. Import an account to restore your data from a backup. If someone gets access to your account seed, they can decrypt your messages and access your data.

Auto-delete settings

Messages are stored in an encrypted format on the server, allowing you to retrieve them after page reloads. Configure how long messages should be kept before being automatically deleted. Select an option from down below.

Interface settings

Select which theme should be used for the webapp interface. Information like this can fingerprint you and make it easier for third parties to identify you, for maximum anonymity leave this on the default dark theme.
