ET911 — Your Life. Encrypted. On Your Terms.

ET911 is the world's safest self-storage vault for life alerts, reminders, documents, and credentials. Every byte is encrypted on your device with AES-256-GCM before it ever touches the cloud. Only you hold the key — true zero-knowledge.

What ET911 protects

Encrypted document vault with expiry reminders (passports, licenses, insurance, wills).
Password and credential manager — client-side AES-256-GCM, Argon2id key derivation.
Smart reminders and life alerts that work offline.
Family coordination and shared access without exposing plaintext to any server.
WhatsApp-style multi-device linking with per-device key rotation.

Why zero-knowledge matters

Your passphrase never leaves your device. Servers store only ciphertext. If our infrastructure were ever compromised, your data remains mathematically unreadable.
