EchoVaults is an offline-first, encrypted legacy vault that stores your final wishes, messages, and important information — accessible only in case of death, disappearance, or emergency. It doesn’t rely on servers, cloud, or biometrics. It runs 100% on-device, with zero internet exposure, and uses AES-256-GCM with PBKDF2 encryption. Once set up, no account is needed, and it operates without any background activity or data collection.
