Hi Allen & Abraham,

Temporary files are always wiped / shredded (i.e. overwritten with random data) before deletion. This is the same for both Free and Premium users.

Please note that modern SSD devices often have a feature called “wear levelling”, which causes such wiping to be less secure than it might seem. With the proper software, it’s often possible to recover data that logically is overwritten (but in actual physical fact is not). It’s not trivial, and it can’t be done with regular file recover tools. It needs special software that interacts directly with the SSD device, but the point is that it’s possible.
