HIDDEN PHOTO VAULT
for iPhone/iPad

When deciding how to hide photos on iPhone properly, the default hidden album isn't enough. NuDefndr acts as a true secret photo vault for iOS, allowing you to completely hide private photos on your iPhone without uploading them to a cloud. Secured locally as an encrypted vault with FaceID, your sensitive content is locked away offline. Nobody gets in but you.

Zero third-party trackers. Zero analytics. Open source for total auditability.

Engineered for iOS

Security without Compromise

We combined Apple’s Neural Engine with secure local encryption to create a vault that is as fast as it is private.

Neural Engine Detection

Scanning is handled locally via the SensitiveContentAnalysis framework. The app never "sees" the photos; it only receives a boolean safety score from the OS.

FaceID Sandboxing

The NuDefndr Vault uses a separate storage partition. Even if your phone is unlocked, the vault remains encrypted until you pass a biometric check.

Incremental Intelligence

Optimized for large libraries, tracking file signatures so only new content is processed, saving battery and time.

Open Source Integrity

Don't take our word for it. Our development is actively updated on GitHub.
