## What is ImpCalc?

ImpCalc looks and works like an ordinary calculator. Enter your PIN and press
the delete key, and it becomes a private vault for the photos, videos, files
and notes you would rather keep to yourself.

Nobody browsing your phone finds a locked app demanding a password. They find
a calculator that adds up.
Not a disguise that falls apart when tapped. ImpCalc handles everyday
arithmetic and percentages, and behaves like any calculator until the moment
your PIN is entered. Enter the wrong number and the delete key simply deletes
a digit, exactly as it should — there is no error message, no shake, and no
hint that anything else exists.
WHAT YOU CAN KEEP INSIDE

• Photos from your library, or taken directly in the app
• Videos
• Documents and files
• Private text notes

Organise everything into folders, rename them, and view or export items
whenever you need them.

MORE THAN ONE VAULT

Create additional PINs, each opening its own separate vault. One PIN can lead
to an everyday collection, another to something more private. Each vault sees
only its own contents.
NO ADS. NO TRACKING. NO SUBSCRIPTION.

ImpCalc shows no advertisements and does not track you across apps or
websites. There is no subscription. The free version includes 3 folders and up
to 10 files in each.


PREMIUM — ONE PAYMENT, KEPT FOREVER

A single purchase, not a recurring charge:
• Unlimited folders
• Unlimited files in every folder
• Private text notes

Purchases restore automatically on a new device with the same Apple ID.

PLEASE READ BEFORE YOU START
Because your files live only on your device and nowhere else, deleting the app
erases them permanently. We hold no backup and cannot restore anything. Keep
your own copies of anything important, and remember your PIN — there is no
recovery.
