HideX: Calculator Lock for Android

App summary

Multipurpose calculator HideX: Calculator Lock is a free privacy app for smartphones that disguises itself as a functional calculator. When unlocked with a personal passcode, it opens a hidden area where you can store and manage sensitive content — from photos and videos to entire apps — so they remain invisible to casual viewers.

What you can hide

• Applications such as social networks, games, and shopping tools
• Personal photos, albums and video files from your gallery
• Miscellaneous documents and other file types buried in a secure vault

Storage and recovery

• Built-in cloud backup keeps your hidden items safe and recoverable if your device is lost or reset
• The app offers expandable cloud storage so you can offload content without sacrificing space on your phone

Privacy and browsing protections

• A private web browser and an integrated VPN help reduce tracking and protect online activity
• You can download videos directly from many websites into the protected area for offline viewing

Disguise and usability features

• The app mimics a working calculator and can change its visible icon to stay inconspicuous
• A cloning feature lets you run the same application both inside and outside the hidden environment, keeping workflows seamless

Security alerts and access control

• Set a passcode to access the hidden vault and prevent unauthorized entry
• Optional break-in alerts notify you of suspicious access attempts and capture a photo of the person trying to open the vault

Why users choose it

With millions of installs worldwide and a mix of concealment, backup, and privacy tools, HideX aims to be a comprehensive solution for anyone who wants to keep selected items on their phone private and recoverable.
