Is the twitter DM archive saved anywhere?

[Suemmy]

I have been talking some day with someone on twitter via DM and I have had some important info in there that I forgot to save.
When I wanted to check out,I realised the other person has deleted the DM's so there was nothing left in there.
So I am asking you,once the twitter DM discussion is deleted by the other person (I see it dissapears from me as well), is it still saved and archive somewhere else?Or is deleted forever?
Thank you!
