■ About Nocturne ■
The name "Nocturne" embodies the idea that "cherishing the present creates wonderful memories to look back on in the future." We aim to make the digital world a better place by providing a comfortable messaging app where users can communicate with peace of mind.



Nocturne uses our proprietary digital ID "Ciphergrid," developed with blockchain technology, as the user ID. While it's still in beta and may not always run smoothly, it significantly enhances security and strongly protects user privacy.



We want to reduce the sadness caused by miscommunication and misunderstandings. We want you to cherish and enjoy every message. Keep what's important in your heart and experience richer communication with Nocturne.
