ZERDAVA File Shredder

ZERDAVA File Shredder is android data eraser which securely deletes files leaving them unrecoverable. It contains all secure deletion algorithms. WHAT IS SHREDDING? Shredding is a process of irreversible file destruction, so that its contents could not be recovered. Sometimes the same process is referred as erasing or wiping; we prefer to call it shredding in an analogy with paper shredding machines, which are used for disposing sensitive documents. WHY IT IS NECESSARY? Whether you plan to trade in your old Android phone for a discount on your new phone, sell it on eBay, give it away to a friend, or drop it off for recycling, you’re going to want to wipe it of all your data first. Traditional data removing methods like deleting, formatting and flashing will not entirely remove the data from a device, instead they will just hide this data and make it inaccessible. But anyone can restore those manually deleted files from the free space until the data itself has been overwritten using secure deletion algorithms. With ZERDAVA File Shredder you can easily shred unnecessary files and securely delete your personal files before selling your phone. This application uses Storage Permission to: - Effectively safely delete files on your Phone, SD Card or OTG device.
