Question 1

What is Atlas Associates Inc.?

Accepted Answer

Atlas Associates Inc. (legal name: Atlas Associates株式会社) is a Japanese DefenseTech corporation pioneering post-quantum cybersecurity, quantum-resistant end-to-end encryption, and offline disaster-resilient communications. Founded on February 22, 2019, by Founder and CEO Takayuki Miyano, the company builds the Arc secure messenger, the local-first Mac screen recorder Atlas Helios, and sovereign communication infrastructure for high-security environments.

Question 2

What makes Arc messenger unique compared to other apps?

Accepted Answer

Arc is the world's first defense-grade messenger combining NIST-standardized Post-Quantum Cryptography (ML-KEM-1024 / PQXDH) with the Signal Protocol Double Ratchet, alongside offline Bluetooth Low Energy (BLE) store-and-forward mesh networking. It requires no phone number for registration, operates with strict zero telemetry, and features sender-controlled Mutual Burn (Vanish-on-Read) message retirement.

Question 3

Why is Post-Quantum Cryptography (PQC) essential today?

Accepted Answer

Adversaries and nation-state threat actors are actively conducting 'Store Now, Decrypt Later' (SNDL) attacks—intercepting and storing encrypted high-value communications today to decrypt them when quantum computers mature. Arc prevents retroactive decryption by implementing a hybrid post-quantum handshake uniting classic Curve25519 with quantum-resistant lattice-based ML-KEM-1024.

Question 4

How does Arc offline mesh communication work during disasters and network outages?

Accepted Answer

When cellular towers, fiber networks, or internet backbones fail due to earthquakes, natural disasters, or intentional network blackouts, Arc devices automatically establish peer-to-peer Bluetooth Low Energy (BLE) connections. Encrypted messages are relayed hop-by-hop (Store-and-Forward) across nearby devices until reaching the recipient, enabling critical crisis communication with zero infrastructure.

Question 5

How does Arc differ from Signal, WhatsApp, and Telegram?

Accepted Answer

Unlike Signal and WhatsApp, Arc does not mandate a cellular phone number, preventing SIM-swap and identity correlation. Unlike Telegram, Arc employs genuine E2EE by default on all 1:1 and group chats. Crucially, Arc provides native offline BLE mesh routing and post-quantum ML-KEM-1024 encryption, which no mainstream messenger offers.

Question 6

What is Atlas Associates' privacy and data sovereignty guarantee?

Accepted Answer

Atlas Associates has zero advertising, zero trackers, and zero data monetization. Messages are end-to-end encrypted so server infrastructure never possesses decryption keys. Cryptographic keys remain isolated within the device's secure hardware enclave. The company adheres to a strict zero-telemetry policy and maintains absolute independence from sovereign surveillance pressures.
