CalcSafe: Privacy Vault is an innovative utility app designed for Android users that combines the functionalities of a calculator with advanced security features. This app allows users to store private files, photos, and notes in a secure, encrypted environment. The vault is protected by AES-256-CBC encryption, ensuring that all imported files remain inaccessible to unauthorized users. Users can easily organize their files into custom folders and choose between encryption or hidden modes for added security.

In addition to file storage, CalcSafe offers a private camera feature for capturing photos directly into the vault without leaving traces in the device gallery. The app also includes intruder detection, which captures a selfie of anyone who tries to access the vault with the wrong PIN. Additional features such as a decoy mode, customizable app icon themes, quick-lock options, and multi-language support make it an ideal choice for anyone looking to enhance their digital privacy.
