How to Hide Private Photos in an Encrypted Vault on iPhone

TL;DR

CleanMaster's Secret Vault moves private photos and videos into an encrypted store (AES-GCM, Keychain-backed) that you unlock with Face ID or a PIN — so sensitive media stays private even if someone has your unlocked phone.

Steps

Open CleanMaster and go to the Secret Vault.
Set up your unlock — Face ID or a PIN.
Move the photos and videos you want private into the vault.
They’re stored encrypted (AES-GCM, Keychain-backed).
Unlock with Face ID or your PIN whenever you need them.

Why it works this way

Handing someone your unlocked phone to show one photo shouldn’t expose your whole camera roll. The Secret Vault gives sensitive media a separate, encrypted home behind Face ID or a PIN, so it isn’t sitting in the main library for anyone swiping through to stumble on. Encryption is AES-GCM with keys held in the Keychain, and it’s entirely on-device.

Tips & edge cases

Set a PIN as a backup to Face ID so you’re never locked out.
Move, don’t just copy — leaving the original in your library defeats the purpose.
On-device only — there’s no cloud copy of your vault.

FAQ

How is the vault secured? Media is encrypted with AES-GCM and Keychain-backed, unlocked by Face ID or a PIN.

Are vault items still in my main library? You move media into the vault so it’s kept private and separate from the regular library.

Is anything uploaded? No. The vault is on-device; your private media stays on your phone.
