'do not delete data base' when prompted UNLESS...

‘do not delete data base’ when prompted UNLESS you permanently want to delete all personal data files, folders, emails.
This should be more clearly explained in the uninstallation prompt as many don’t realize this. 

For me it is pretty clear that this is going to delete the database if I select Yes , but I guess delete has different meanings to different people. At least by default is is set at No , so if you hit Enter by mistake there is no loss.

I would actually suggest that uninstalling the application does not even prompt to delete the data, like it was before, then there will be no problem.
