Etergis

Etergis is a secure personal secret orchestration platform built around the Lifeline — a smart dead-man switch. If something happens to you, your encrypted secrets are automatically delivered to the people who need them.

HOW IT WORKS
• Store secrets with end-to-end encryption (AES-256-GCM), encrypted on your device before it ever leaves
• Assign recipients who receive your secrets if your Lifeline countdown expires
• Check in regularly to keep the countdown reset — or set it and forget it
• Miss a check-in and recipients are notified; secrets release after a grace period

KEY FEATURES
• End-to-End Encryption — Secrets are encrypted on your device before leaving it. We have zero knowledge of your content.
• Per-Recipient Key Wrapping — Each recipient gets their own cryptographic key to your secret, wrapped so only they can unwrap it.
• Lifeline (Dead-Man Switch) — Configurable countdown with reminders at intervals you choose (email and SMS).
• Time Capsules — Schedule an encrypted message or file for a future date. No countdown needed — it delivers automatically when the date arrives.
• Safety Check-In — Quick, short-timer check-ins for solo travel, hikes, first dates, or anywhere you want backup. Miss your window and your trusted contact is notified.
• Emergency Keyword Trigger — Set up a keyword that releases a secret ahead of schedule.
• Two-Factor Authentication — Optional TOTP with single-use backup codes.
• Recipient Management — Add trusted contacts who receive your secrets when needed.
• Biometric App Lock — Face ID / fingerprint app lock, processed entirely on your device.
• Subscription Plans — Free tier available (3 secrets, 2 recipients). Personal and Family plans add more secrets, more recipients, and SMS notifications.

USE CASES
• Emergency access to critical accounts for family members
• Personal safety for solo travel, hikes, first dates, or anywhere you want a backup plan
• Time-locked messages for birthdays, anniversaries, or future milestones
• Business continuity — ensure partners can access essential credentials
• Digital estate planning — pass along important information automatically
• Whistleblower protection — release information if you become unreachable

SECURITY FIRST
• AES-256-GCM client-side encryption — content is encrypted before it ever leaves your device
• Argon2id key derivation and password hashing
• TLS 1.3 encryption in transit
• Optional two-factor authentication (TOTP)
• Biometric app lock with configurable auto-lock
• No ads, no tracking, no data selling — ever

Built for people who take security seriously.
