I'd like a reference to this policy in writing, so a link to one of their published pages would be great. If the answer is "immediately," that's great (and I fear I won't be able to find that in black-and-white). But if it's that they purge all of the files marked for deletion within X days of the user having chosen to delete them... I want that. I want to know so I can refer to this Jira policy when describing my own data destruction compliance.
