[This letter was the response I received from Gobbler Support]
 
Hi Geoff,
 
Your expectations of privacy are certainly reasonable, and we should be in line with those expectations.
 
If you sent files/projects to someone, we would not have captured any extra data, or written files to your drives other than some temp files for compression/encryption on your system drive. Those temp files are deleted when the upload is completed.
 
If you backed these three projects up to the Gobbler cloud, then Gobbler had to scan one or more of your drives before they could be backed up. This process is very straightforward: When you click the Scan button (and not before!), Gobbler scans the selected drive. looking specifically for DAW files (.ptx, .logic, etc.). Gobbler then saves a list of those DAW files and the related sub-folders where the supporting media files are stored. It does this so that as files are added to those folders, Gobbler will know to back them up automatically.
 
Gobbler does not scan your system folder or your applications folder. It does not store information about folders which do not contain DAW files. It does not capture or transmit data about your usage, and it does not scan any drives which you don't tell it to scan yourself.
 
I am not sure if we still write files to your drives, but I will check. At one time, we wrote small databases which contained the info about the DAW files on that drive, but that was all.
 
As for deleting those projects from the Gobbler cloud, that shouldn't be a problem:
 

Open the Gobbler client and click Files in Gobbler on the leftDouble-click one of the projects in the listClick "Remove from Cloud" in the lower right-hand corner 
Please let me know if this doesn't answer your questions, or if you still have concerns.
 
Thanks,
      Gordon
