Calculator Lock: Encrypt Files is an Android app developed by Fantastic Light. This cleverly disguised app functions as a calculator but serves as a hidden space to encrypt and hide various types of files like photos, videos, documents, and more. The app ensures the safety and privacy of your files by deeply encrypting them, making them inaccessible to other apps or the system's photo album.

The app offers a secure and reliable way to protect your files by requiring a password entry through the calculator interface to access the hidden space. Once inside, users can hide videos and photos securely, with all files being deeply encrypted and inaccessible without the password. Additionally, the app provides file management features, including a built-in photo album, high-definition video player, and support for folder classifications and file sorting.
