Calculator Vault is a discreet app that functions as a regular calculator on the surface, but secretly hides pictures, videos, and locks apps to provide enhanced privacy and security. With the appearance of a standard calculator installed on your phone, this tool effectively conceals your files within a secure vault. Access to the hidden content is granted only after entering a numeric PIN on the calculator panel.

This versatile app also serves as a practical calculator for everyday use. In addition to its primary functionality as a vault, it offers various features to safeguard your privacy. Lock your apps from prying eyes by selecting them within the App Lock tab on the main screen. Enabling the intruder selfie feature captures a photo of anyone attempting to gain unauthorized access, while the fake cover provides an extra layer of security by displaying a misleading interface when opening locked apps. Fingerprint app lock compatibility allows for quick and convenient access to locked apps using your registered fingerprint.
