Not really a worry because they cant get what ddg doesn't have.

Is there even evidence they don't keep anything?

Edit: Okay, you can't really have evidence of absence, but good reasons to believe they don't log?

They state all over in their website that they don't log.

Though I have no way of verifying they don't keep logs, if I discover they do: at least I can sue them for it.
