AbsentKey

A mobile encrypted vault that stores passwords, photos, files, notes, recovery codes and IDs with on-device AES-256-GCM encryption and offline access, addressing insecure storage in notes apps and uncontrolled sharing of sensitive information. It is for individual consumers and households including families, couples, and people planning inheritance or emergency access for trusted contacts. It is delivered as a free local-only app with unlimited secrets and optional paid sharing that allows per-recipient rules for instant, approval-based, or timed release with encrypted cloud backup.
