Encrypted photos, videos, files and notes

NullVault is a private photo and video vault for iPhone and Android. It encrypts imported content, filenames, metadata and managed previews inside separate pattern-addressed spaces. Core local use works offline without a NullVault account; optional online services and purchases are separate.

The feature

Why it matters

Keep private media, documents, files, and notes together as encrypted content inside one pattern-addressed vault.

One encrypted home for private content

NullVault is not limited to a hidden photo album. Photos, videos, documents, arbitrary files, and private text notes can live together inside the active encrypted vault.

Filenames, metadata, thumbnails, and file contents are encrypted at rest. The app decrypts only what an authorized vault session needs to display, preview, play, search, or export.

Private viewing and playback

The authorized gallery can display photos, play supported video formats, preview supported documents, and open text notes without requiring a permanent plaintext export.

On Android, videos remain in their original format, and photo imports can preserve original quality or use Storage Saver to reduce file size. That import-mode choice is not advertised for iPhone. Preview and playback support depend on the device and file format.

A deliberate import and export boundary

You choose what enters the active vault. Importing creates a protected NullVault copy but does not guarantee removal of an original from a gallery, synchronized service, Recently Deleted, or an earlier backup.

Export creates a decrypted copy outside NullVault. From that point, the destination app, storage provider, gallery, and any connected cloud service control the new copy.

Questions about this feature

What can I keep in a NullVault vault?

Photos, videos, documents, arbitrary files, and private text notes can be stored as encrypted vault content. Preview support depends on the device and file format.

Are previews and filenames encrypted too?

Yes. NullVault encrypts its managed filenames, metadata, thumbnails, previews, and file contents at rest.

Does importing remove the original?

No universal deletion guarantee is made. Source galleries, synchronized services, Recently Deleted, exports, and backups must be reviewed separately.
