🔐 Mitilena Offline Signer – Professional Solution for Institutional Security

The app physically cannot connect to the internet. All operations happen only on your device. Everything stored inside is encrypted with military-grade algorithms — so strong it would take more than 400,000 years to brute-force.

📱 ATTENTION MODERATORS AND USERS
