Empty app state
What Is a Duress Password?
A secondary password designed for extreme situations where you may be forced to unlock your device.
Silent Panic Action
A secondary password that triggers a hidden response. The app opens normally — but your data is hidden behind a decoy empty state.
Plausible Deniability
An attacker sees an empty app and has no way to tell that data ever existed. Zero visual difference from a fresh install.
Always Recoverable
Your data stays safe on disk. Enter your real password anytime to restore everything — nothing is ever deleted.
How It Works
From setup to activation — what happens when a duress password is entered.
Setup
Set a duress password in app lock settings. Must be at least 4 characters and different from your real password.
Duress Entered
Enter the duress password at the lock screen. Notes are cleared from memory and the app opens to a convincing empty state. Data stays safe on disk.
Undetectable
There is zero visual difference between a duress unlock and a fresh install. Enter your real password anytime to restore everything.
How It Protects You
Two passwords, two completely different outcomes. Your data is always safe.
Opens a decoy empty app. Notes are cleared from memory but preserved on disk. Looks identical to a fresh install — no trace of your data.
Restores everything. All your notes, pages, and data come back exactly as you left them. Enter it anytime to return to normal.
