Calculator

The Calculator ingeniously disguises its true purpose as a vault to secure personal media files, enabling users to maintain strict privacy on their devices. At first glance, it functions as a typical calculator, but it also features robust security mechanisms to hide pictures, videos, and lock apps behind a Numeric PIN.

To safeguard media, seamless addition of files is integrated through a straightforward locking mechanism straight from the gallery. Locking enhances protection, allowing only authorized access to selected applications, fortifying privacy on the device. The Intruder Selfie function captures a photo of any unauthorized individual attempting to access the vault, further anchoring its security credentials.

Dual security layers through a Fake Cover and Fingerprint unlocking cater to different preferences for access protocols. Alongside classic PIN pad protection, the tool supports fingerprint authentication for faster access, available on compatible devices.

Noteworthy features include support for various file formats, customizable themes, secure app protection to prevent accidental uninstallation, and an intuitive image viewer with functions such as slideshow and sharing capabilities. Dark Mode ensures discreet usage at night, while this platform cleverly avoids listing in recent apps for enhanced privacy.

In cases of forgetting credentials, recovery options via a registered email are assured, supporting password changes and media unlocking as needed. Additionally, there's a theme customization feature to refresh the user interface.

Users should note that uninstalling the game without restoring files will result in permanent loss, which emphasizes the importance of careful file management. User feedback remains central to continuous improvement, inviting suggestions for advancements. Remember, Calculator employs the Device Administrator permission and Accessibility Service, ensuring a high level of security for users.
