Why We Require "All Files Access" (Android 11+)
Calculator Vault requires "All Files Access" (MANAGE_EXTERNAL_STORAGE) permission on Android 11 and above to perform its essential functions — hiding and restoring photos, videos, documents, and files from any folder on your device. This permission enables the app to move files to a private location and later restore them to their original path as per your command.
