I'm looking to obtain a list of another user's posts that I have upvoted. I learned in a previous question that this is not possible through the Stack Exchange Data Explorer, because any private data, including up/down votes, are not included in the SEDE data dumps.

That left me wondering: Is such a list theoretically possible to obtain by writing my own app that uses the Stack Exchange API? If so, are there any apps that anyone has written that already do this?
