Shredder is an application to permanently erase files and directories on smartphone or tablet. After the data has been shredded, it will not be possible to recover from storage. Therefore, it should be used with great carefulness. Almost everyone these days have a large amount of very private data on their devices. You can't just use regular 'delete' on them. This will simply remove the file from the directory structure, but the real data will not be erased, and someone knowledgeable can still get it back.
You should shred your "top secret" privacy photos, videos, work information etc. etc.
If you are an entrepreneur, celebrity, politician it is must have tool for you.
It could save you millions of lost dollars (if somebody will recover the secrets of company you own or have worked for).
Don't use cloud sync as this way you give potential access to your private files to everyone around the world.
If you want to copy files to the PC/laptop or second smartphone or tablet, use USB (highly recommended method!), custom made secure WiFi Hotspot, or secure Bluetooth.
