Side-by-side

Question NullVault for iOS Apple Hidden collection
Available now Yes Yes
Remains inside Photos No, for the app-managed vault copy Yes
Uses Face ID, Touch ID, or device passcode boundary Platform protections participate Yes, locked by default
Separate pattern-addressed spaces Yes No
iCloud Photos sync Separate vault backup design Hidden state syncs when iCloud Photos is enabled
Photos, files, documents, and notes Yes Photos and videos

Apple documents that hidden photos leave the Library, ordinary albums, and Photos widget; the Hidden collection is locked by default on current systems. If iCloud Photos is enabled, the hidden state follows the photo across signed-in devices. See Apple’s official Hidden album guide.

Which is best for convenience?

The Hidden collection. It is built into Photos, needs no migration, and supports the editing and library experience you already use.

Which is best for an independent privacy boundary?

NullVault is stronger when the requirement is a separate encrypted app-managed copy and a credential that selects one private space without displaying the others. Its current App Store listing and feature documentation define the exact released boundary.

Example: Ava hides gift photos for two weeks; Apple’s built-in option is appropriate. Ben wants encrypted identity documents separated from Photos, with a distinct recovery credential; that is a NullVault use case.

Bottom line

The Hidden collection is the simplest iPhone option for casual library privacy. NullVault adds stronger compartmentalization, broader content types, independent patterns, and encrypted backup outside the iCloud Photos library model.
