When is the streak broken?
I logged in slightly before midnight in order to keep my streak, but it was already broken. What did I do wrong? How does the system work?

I'm not 100% sure about this, but it could be that Duo uses its midnight--whatever time zone Duo is headquartered in--rather than your local midnight as the cutoff. That could be why you lost your streak before midnight, when you thought you still had time to get points and keep it going.
