That means that when you remove information from V0LT, it is deleted entirely from all records on the site. If you'd like to delete your information from V0LT, unfortunately you'll have to do so manually, since your activity isn't tied back to your account in a way that's easy for a program to manipulate. For example, if you'd like to delete your data for the cloud stored notes service, simply open the notes service, delete all the text it contains, then press 'Submit'.
