🧮 A vault that hides in plain sight

Calculator Vault for Android

Lockilee can disguise your entire vault as a working calculator. Everyday use looks like doing math; your secret code opens the real, encrypted vault instead.

Sometimes the safest vault is one that doesn't look like a vault

A vault app with a lock icon on your home screen tells anyone browsing your apps exactly what it is, even if they can't get inside it. A calculator vault sidesteps that problem entirely — it looks like one of the most unremarkable apps on your phone.

Lockilee's calculator vault is a real, working calculator for everyday use. Enter your secret unlock code on the same keypad instead of a calculation, and it opens the actual encrypted vault behind it.

How it works

One app, two identities

🧮

Everyday calculator

Does real math — addition, subtraction, multiplication, division — like any calculator app.

🔑

Secret unlock code

Enter your own chosen code on the keypad to switch from calculator to vault.

🔒

Same encrypted vault

Once unlocked, you're in the same Private Vault — photos, videos, documents and files, encrypted on-device.

🏠

Same icon, same name

Nothing about the app's icon or listed name on your home screen changes.

FAQ

Frequently asked questions

Is the calculator a real, working calculator?

Yes. It performs actual calculations like any calculator app — that's what makes the disguise convincing rather than an obvious fake screen.

How do I open the real vault from the calculator?

By entering your secret unlock code into the calculator's keypad instead of doing a normal calculation. That code opens the actual encrypted vault.

Can someone tell it's not a normal calculator app just by looking?

No — the icon, name and everyday behavior match a regular calculator app. There's no visible indicator that a vault is hiding behind it.

What's the difference between Calculator Vault and Calculator Disguise?

They describe the same feature from two angles: the vault is what you're protecting, and Calculator Disguise is the mechanism — the calculator appearance — that hides it.
