Arc: The Intelligent Messaging App for the NextGen

Arc, an acronym for Accessible, Reliable, and Confidential, aims to be a "bridge between people" that is accessible to all, highly reliable, and ensures confidentiality. Arc inherits the strong foundation of Nocturne and has evolved even further.

The Evolution of Arc: True Privacy for Everyone
Arc provides E2EE (End-to-End Encryption) for all users, including those on the free plan. This ensures your messages can only be read by you and the recipient.

Ultimate Peace of Mind and Freedom, in Your Hands

★ Core Concept: Ignite the Fire ★
In Arc, messages automatically disappear from all devices and servers after a specified period. This concept, "Ignite the Fire," embodies our philosophy of sparking free and heartwarming communication, untethered from digital records, along with our wish for you to cherish every single conversation.

★ Key Features of Arc ★

Connect Anywhere
Our proprietary mesh network feature allows you to exchange messages with nearby users even without an internet connection. Stay connected with your loved ones during disasters or in areas with poor connectivity.

Richer Communication
Enhance your communication with diverse features like ephemeral group chats, a show/hide read receipts feature (Premium), and our unique "Emo" expressions.

Future Developments
We transform your feedback into progress and will continue to evolve with updates approximately every two weeks.
