Locked Secrets Diary

The diary that never reveals the truth.

Most diary apps protect your notes until someone asks you to unlock them.
Locked Secrets Diary is different. It never tells anyone whether a PIN is right or wrong.

Enter your real PIN and you'll see your private diary.

Enter any other PIN and the app opens normally - without warnings, error messages, or suspicious behavior. It simply shows the diary for that PIN, whether that's an empty vault or convincing decoy entries you've prepared.

Only you know which PIN unlocks your real life.

Privacy designed for the real world.

Sometimes privacy isn't about hackers.
It's about moments when someone asks, expects, or pressures you to unlock your phone.
Locked Secrets Diary gives you something ordinary diary apps cannot: plausible deniability.

• Your real PIN opens your private journal
• Every other PIN is also accepted
• The app never displays "Incorrect PIN"
• There are no warning messages
• There is no clue that another, more private diary exists

If someone asks for your PIN, you can provide a different one. The app behaves exactly the same, showing only the entries associated with that PIN. The truth remains yours alone.
Even we can't read your private entries. Your secret diary is encrypted before it ever leaves your device, making it unreadable to anyone except you.

Security that works when it matters.
Your privacy should never depend on remembering to hide your screen.

That's why Locked Secrets Diary includes thoughtful protections built for everyday life:
• Every PIN creates its own completely separate encrypted diary
• One-tap Instant Exit immediately leaves Secret Mode and returns to your regular diary
• Automatic lock after 30 seconds of inactivity
• Face ID and Touch ID support for fast, secure access
• Private entries remain isolated from your everyday journal
• Multiple secure vaults for different levels of privacy

Your everyday diary - plus your private one.
Locked Secrets Diary isn't only about security.
It's also a beautiful journal you'll enjoy using every day.
Record daily moments, organize thoughts with tags, track your mood, browse your memories in calendar view, and quickly search past entries.
Use your regular diary for everyday life while keeping your most personal thoughts protected inside your private vault.
