The software provides four data cleaning modes, namely quick cleaning, private data cleaning, partial cleaning and complete cleaning. You can choose one of them according to your needs.

Quick cleaning: you can clean up all kinds of junk files (invalid files, temporary files, cache files, etc.). ) to help users release storage space;

Completely clear: all data can be cleared, and the device can be restored to the factory settings, but it has no impact on the iOS system and does not need to reinstall the system;

Partial Erase: This mode only erases all the deleted files on the iPhone and makes them unrecoverable, and has no effect on the existing files on the device. (After selecting one mode, other modes are not available).
