App Features

• Disguised Access
  At first glance, it’s just a standard calculator. Enter your secret password and hit the √ button to reveal your private content—easy and discreet.

• Secure File Manager
  Store your private photos and videos securely, away from prying eyes. Import from your albums and stash them safely within the app. When needed, you can still share them to other apps—email, cloud drives, or whatever you like.

• Private Contacts Section
  Hide contacts you don’t want in your regular address book. Add as many secret contacts as you need, attach detailed notes, or quickly send messages straight from inside Calculator Vault.

• Personal Notes Locker
  Keep as many notes as you want, tucked away from your main notes app. Great for anything from reminders to sensitive info.

• Built-in Private Browser
  Browse the web right inside Calculator Vault without leaving a trace in your main browser. Bookmark favorite sites and manage them privately.

• Auto-Camouflage & Security Touches
  Calculator Vault automatically goes back to the calculator screen whenever you leave the app, covering your tracks fast. For extra security, there’s even support for a fake password, in case anyone ever pressures you for access.

• Manual Backup Option
  Your hidden files are stored locally in a secure folder. If you ever want to back up everything, you can do it manually at any time.

Whether you’re opening Calculator Vault on your phone or testing it out on BlueStacks, you get seamless tools for privacy without drawing attention.
