A new Windows app called Secure Calculator Vault disguises file management within a calculator interface, encrypting user files with AES 256 encryption. It includes a built-in media viewer for images, videos, and text files, allowing users to view content without leaving the app. Files are decrypted only when removed, giving users full control over their data.

The app operates entirely offline, requiring no internet connection, and avoids ads, analytics, or any background tracking. This privacy-focused design appeals to users wary of cloud-based services and data collection. It's available as a one-time purchase on the Microsoft Store, optimized for Windows 10 and 11.

This tool addresses a niche but growing demand for simple, local encryption utilities. While dedicated encryption software exists, combining it with a discreet interface and offline operation makes it accessible for everyday users. Its success will depend on user feedback and its ability to handle diverse file types reliably.
