"A next-generation Time disappearance & Fintech messaging app 'Nocturne’, Operating on a blockchain-based user database and Digital ID,
Implementing enhanced end-to-end encryption (E2EE) with consideration for high security and user privacy.

It connects people through a mesh network, even in environments without internet access."


Starting in June, we have begun releasing Nocturne NextGen, which currently offers only the chat feature. We will be conducting test marketing over the next three months.

The implementation of the Meshnetwork is planned within a few months, point accumulation by the end of this year, and the utilization of points is scheduled for next year.


Secure Ignite the Fire (IGF) Chat

This app automatically erases all user messages from devices and servers after a specified time upon going online. It ensures complete privacy as messages are neither monitored nor used for data collection. 

AI Chat (Coming Soon)

We plan to conduct machine learning internally based on the content sent by users in this chat. We won't have any knowledge of who is asking our AI what.

The collected data will be used as anonymized big data for our future product development, marketing analysis, and collaborations with other companies. We will build it based on Gemini.

Mesh Network (Coming Soon)

Through our partnership with Bridgefy, communication within Nocturne is possible even when the internet is not available. This feature can be utilized during emergencies such as earthquakes or other disasters, as well as in situations like flights or sports events, enabling temporary community formation.


The app operates on a user database and digital IDs developed through blockchain technology. This approach not only ensures enhanced security measures but also creates a borderless experience worldwide, enabling personal authentication from anywhere. It also incorporates functionalities as a hub, with APIs for integration with various global services.

Digital ID

Digital IDs facilitate secure, fraud-free personal verification and the management of connected services.

We also provide APIs for businesses, enabling logins across various platforms.Additionally, there are plans to store data like healthcare records in the future.


By the end of 2024, users will be able to earn points by viewing ads in Nocturne. Plans are underway to enable the exchange of Atlas' points earned in our app into various global digital currencies through the digital ID system and Metamask. Additionally, the functionality for sending and receiving points will also be introduced.

Protect user privacy

We do not monitor or utilize the content of users' messages in our chat service. However, for AI Chat, we use the data as training material for AI improvement. After the timed expiration (IGF: Ignite the Fire), messages are completely deleted from our servers. Nonetheless, in the event of a criminal incident, we may request disclosure from the server provider we use Google.

Enhanced E2EE (End to End Encryption)

Like WhatsApp, Telegram, Viber, and Signal, we use equivalent encryption for communication. However, unlike them, we do not weaken encryption for message transmission due to our policy of not monitoring or repurposing messages for advertising. This means that after initiating IGF (Ignite the Fire), users' communication privacy is completely secure.

Nocturne NextGen

One of the World's Most Secure Messaging Apps

 Nocturne offers unparalleled security, automatically deleting all sent and received messages from all devices and servers once you come online after the designated time for a message. Enjoy secure communication with your loved ones, enhanced with unique features like emotion icons.

The name "Nocturne" comes from the idea that "cherishing the present creates wonderful memories when looking back in the future." We want you to cherish every message and enjoy them. We hope to reduce the sadness caused by the inability to express emotions properly or misunderstandings. We aim to create a market that improves the digital world through a messaging app that makes our users feel comfortable.


Privacy Protection

Nocturne does not monitor, transfer, or sell the content of any messages sent or received. All messages are set to disappear after a certain period of time. Furthermore, messages are end-to-end encrypted and not stored on either device or any servers after they disappear, so there is no risk of message content being leaked. We also fully comply with the European Union's General Data Protection Regulation (GDPR) and manage data based on strict data protection standards.

Automatic Message Deletion

Ignite the Fire ( IGF )

Sent and received messages are automatically deleted from all devices and servers upon the next app launch after the default setting of one day.

The maximum setting is up to 7 days. In individual chats only, you can extend the message lifespan for an additional 28 days from the time of sending by pressing the ☆ button.

Secret Mode

With Nocturne's Secret Mode, you can send confidential information, such as passwords, without revealing it.

Emotion Icons

Nocturne features a unique function that allows you to attach emotion icons to your messages. With a wide variety of expressive icons, you can easily convey your feelings and emotions to others, going beyond what words alone can express.

Enlargement Effect

Enclose your text with emojis at both the beginning and end to enlarge the sent message (may not work on some devices). You can also tap on emotion icons to enlarge them for a more enjoyable experience!

Convenient Features

Nocturne features a simple and intuitive interface, just like other messaging apps used worldwide, making it easy for anyone to use.

It comes with a variety of features, including group chats, point usage*, and mesh network*.

*Point usage and mesh network are not yet available.

In the future, you will be able to use points to send animations to other users, unlock features, and exchange them for various digital currencies. Stay tuned for updates!
