The Ultimate Photo & Video Vault

FREE FOREVER

Our app allows you to conceal sensitive photos, videos, and files. Once safely tucked away, you can delete these items from your phone’s main gallery while they stay available in your calculator-alike photo vault.

Please keep in mind that you are the ONLY person who gets access to the secret photo gallery. We do not use any cloud storage functionality for your privacy and security. That said, it is essential to write down your password and store it safely.

Stealthy, Yet Functional

Masks As Calculator

Transform LOCKED into an everyday calculator! To the unsuspecting eye, this secret photo app appears as an ordinary calculator. It cleverly doubles as a regular calculator, blending seamlessly among your everyday apps. Behind this façade, it serves as a formidable safe for your private content.

Multiple Lock Methods

LOCKED provides multiple lock methods to secure your private gallery and files. Choose from pin codes protection, pattern lock, or fingerprint authentication to ensure your data remains inaccessible to others.

Advanced Security Features

The LOCKED app is more than just a calculator vault app or a calculator app lock. Instead, it provides uncompromised privacy by securing your photos and videos with password protection. On top of this, we employ military-grade AES encryption, similar to what international corporations, banks, and governments use, to offer unparalleled security for your files.

Secure and Private Browsing

100% Privacy

Browsing privately is effortless with LOCKED’s built-in browser. This enables you to navigate the internet without leaving any traces and directly download content into your vault. It is not a secret that most of the large sites collect all of the data they can reach through your device: your adjacent accounts, identities, etc. So now you can visit your favorite sites without connecting to your real life accounts!

Decoy Vault

The LOCKED app also features a decoy vault, adding an extra layer of security. This function opens a fake vault, effectively misleading any potential intruder.

Intruder Alert

Our Calculator hidden app features the Intruder Selfie function. This captures a photo of anyone attempting to access your vault and records their attempts and creates break in report.

Secret Diary

Absolutely Safe

Jot down sensitive information or personal thoughts in your secret diary, a feature within LOCKED’s vault. Your private notes, confidential thoughts, and ideas are as safe as your hidden photos and videos.
