Yes, it will delete all your data if SSD used in your system is FDE drive , as this software uses the mechanism to reset the Cryptographic Key used for encrypting the data.

 

What is FDE cryptographic erase?

"Each FDE drive has a unique encryption key, through which the data is processed real time as it is saved to the media.  Each FDE drive saves different bit patterns to the media given the same original data, while non-FDE drives save the same bit patterns to the media.  The cryptographic key is also used to decrypt the data.  If the encryption key is changed in any way, all data on the drive becomes useless bits.  The only way to read the data again would be to restore the originating encryption key."

So its pretty safe to use this software for cleaning your system SSD.
