Store description excerpt

Arc: Sovereign Dual-Tech Messenger We are still an unnamed startup, but we have destroyed the concept of messengers from the ground up to protect user privacy and communication freedom from unauthorized surveillance and data interception. While currently a beta version centered on DMs (individual messages), we are releasing it early so you can experience our world-class defense technology (Dual-Tech) directly tied to national sovereignty, individual sovereignty, and security during emergencies. ・National Security-Grade Multi-Layered Defense Post-Quantum Cryptography (PQC) Hybrid Key Exchange Standardizing "PQXDH + ML-KEM-1024" to completely neutralize decryption threats from future quantum computers (Harvest Now, Decrypt Later). AEGIS (Arc Enhanced Guard & Integrity System) Digital Signature Our proprietary technology that mathematically guarantees message authenticity. Completely eliminates tampering, impersonation, and man-in-the-middle attacks. Complete Anonymization (Sealed Sender) Absolute privacy where even the server cannot know metadata like "who sent what to whom and when," let alone the communication content. ・Aesthetics of Disappearance — Instant Data Erasure 48 Disappearance Animation Patterns Based on the core concept "Ignite the Fire (IGF)," a beautiful animation triggers when a message disappears, completely erasing data from servers and devices without a trace. Delight Reaction Function Sending specific icons triggers random animations, bringing new color to private conversations. ・Independent Mesh Communication Even in Infrastructure Collapse BLE Mesh Network Even during "emergencies" when the internet or cellular networks are completely down due to communication outages, disasters, or censorship, users can safely relay and exchange E2EE messages via Bluetooth (BLE) with nearby devices. ・Zero Server Exposure Complete On-Device AI (Coming soon) Independently Operating AI Characters We are developing translation AI "Rosetta" and summarization AI "SUM" that operate standalone purely within the device (locally), completely eliminating data exposure to external servers or clouds. ・About Early Access (Beta Testing) Free Access Until August 31, 2026 All premium features are unlocked without credit card registration. Currently, the DM function is fully operational. Notice Regarding Updates To prioritize security enhancements and optimization, high-frequency updates may cause past messages to become un-decryptable (data reset). Please maintain alternative contact methods if necessary. Uncompromising aesthetics and top-tier defense technology (DefenseTech) from Japan bring true privacy and communication freedom to the world.
