Secret diary with a password: how to keep it truly private

A diary is the place for thoughts that are nobody else's business. But a secret diary only stays secret as long as nobody can look inside. Here's a simple explanation of how to truly protect your diary – and why a password on its own isn't enough.

The problem with a paper diary

The notebook with the little lock is lovely, but it isn't secret:

• The lock is decoration. It keeps curious glances out, but not anyone who really wants to look.
• Hiding places get found. Under the mattress, in a drawer – sooner or later the diary turns up when someone tidies.
• Whoever finds it can read everything. Years of your life in a few minutes. You might never even know.

What encryption means – explained simply

Imagine every sentence in your diary is automatically translated into a secret script the moment you write it. "Today I fell in love" becomes something like "k8#Qz!v2Lm@9xR…". Only one key can turn the secret script back into words: your code.

That's encryption. Your diary isn't just locked away – it's made unreadable. Even someone who gets hold of the stored data sees nothing but meaningless characters without your code.

What matters is where it happens. It's safest when encryption happens right on your iPhone and the key never leaves your device. Then there's no other place where your diary sits around in readable form.

Which risks disappear with encryption

Risk	Paper	Cloud app	Vaulted Moments
Someone finds your diary	Reads everything	Often just a password	Unreadable without code
Hacked server	No risk	Possible	No server of our own
Provider reads along	No risk	Possible	No key
Ads and profiles	No risk	Common	No tracking
Diary lost	Gone	Cloud backup	Encrypted backup
Photos	Glued in only	Yes	Yes, encrypted

More private than paper. As easy as an app. Without the risks of the cloud.

Vaulted Moments – your encrypted diary.

Why a password alone isn't enough

Lots of people look for a diary with a password. But a password is often just a door: the app asks for a code, while the entries behind it may still be stored readable – on your phone or on a provider's server. A password without encryption is like a diary in a locked drawer made of cardboard.

So ask every app: are my entries encrypted? And where are they stored?

How Vaulted Moments keeps your diary secret

Vaulted Moments is built for exactly this: finally, a secret diary that's actually secret. Like the paper diary you keep just for yourself – except nobody can find it under the mattress and snoop through it.

• Your entries and photos are encrypted right on your iPhone with AES-256.
• No account with us, no journal server of our own – we store no content. “No cloud” means no storage by us, not the absence of optional backup to your own iCloud.
• Encrypted manual backup and recovery code are always free. Premium backs up automatically to your own iCloud; the file is encrypted on your iPhone first and is unreadable without your code – even to Apple and us.
• Protected by your PIN. Leave the app and it locks itself.
• Not even we can read your diary. We don't have a key.
• No ads, no tracking.

And unlike a paper diary, you can keep photos too: a picture, a few words, a feeling – your private feed that only you can see.

Only you hold the key. So pick a code nobody can guess, and keep your recovery code somewhere safe. Vaulted Moments is coming soon for iPhone. If you'd like to be there at launch, join the waitlist at vaultedmoments.com.
