What it does
The Decoy Vault is a complete, separate vault opened by its own passcode from the same lock screen. It has its own albums, its own photos and its own settings. Nothing in it points at the main vault, and nothing in the main vault is visible from it.
When you use it
When someone asks you to open the app and you cannot refuse. A partner, a parent, a colleague, an official. You enter the decoy passcode, the vault opens, and it contains whatever you chose to put there.
How it fits with the rest
The Decoy Vault is one of three passcodes. The main passcode opens the real vault. The self-destruct passcode erases both. Intruder Alerts records anyone who tries a wrong code. Together they cover the case that a lock screen cannot: your phone, unlocked, in someone else's hand.
