Secure file deletion: When you select files to delete, the app performs a multi-stage process:
• Filename scrambling: the file is renamed multiple times with random characters to overwrite its entry in the storage directory.
• Secure shredding: the file contents are overwritten with random values using direct hardware-level sync.
• Directory slot wiping: the space previously occupied by the file name is overwritten 15 times with dummy files to ensure the original name cannot be recovered.
Wipe free memory: Use this to overwrite the empty space on your storage. This ensures that files you deleted before installing this app become unrecoverable. It works by creating temporary files until the storage is full, and then safely remove them.
