Qvaulto keeps your most sensitive documents in an encrypted vault — and, for the files that truly can't be found, in unallocated disk space with no file-system entry at all. Nothing to search, copy, or delete by ordinary means.
Every layer is designed so the one above it can fail safely.
Every file is individually encrypted under its own key, wrapped by a master key derived from your password with Argon2id. The index — names, sizes, timestamps — is encrypted too, not just contents.
Advanced mode moves the vault into unallocated space on the disk itself — no file, no folder, nothing an ordinary "delete" or file search can ever touch.
Add a standard authenticator app as a second step at login, on top of your master password. Optional, and yours to enable when you're ready.
Open images, text, and PDFs straight from the vault, decrypted only in memory. Screenshot and screen-recording tools are blocked where the OS supports it.
Installations are activated with Ed25519-signed codes — unforgeable even by someone who's fully reverse-engineered the application itself.
No cloud requirement, no telemetry by default. The vault lives on your machine, under a password only you know.
Windows, macOS, and Linux downloads appear here as each is released.
