Legacy Vault is an offline, encrypted digital legacy organizer that stores your most important digital information securely. No cloud, no subscriptions, no ads. Features AES-256-GCM encryption, Argon2id key derivation, auto-lock, emergency QR codes for trusted executors, and printable PDF summaries.

What will happen to your accounts when you are gone? Secret Key splits the master password to your password vault among trusted individuals. No single person knows it on their own - only together, at the right moment, can they reconstruct it.
