They mean that everything they wanted to say, they have said. But there might be something else that YOU want to say. So their part is finished but YOUR part might not be. I think it comes from a conversation on a telephone where two people are speaking on either END of the line. Hope that helps!

Hello! It depends on the context which is not totally clear to me but here is what I think it means: That's all "on my end" often refers to "my responsibilities are done or taken care of." For example, "I will do my end of the work." or "On my end, everything is done." but I think that to say "that's all on my end." could also be said like this: "that's all from my side" which is a phrase that I am more familiar with. It just means "that is all I needed to say/do" or "that is all the information that I have/can give" or "that is all that I wanted to/could contribute". I hope that helps!

Thank you for the answer! :)

Hi phew, It's a way to say, "That's all up to me" or, "These are things that I'm responsible for" or "These are the things I will take care of/ I will do" For example, if I was studying a course and I got a bad grade because I didn't study, 'That's all on my end" - because it was up to me to study and I chose not to. EDIT: I would also use it as Darren Quinn suggested too. (probably more so actually) If I finish presenting at work and I have nothing else to say. "That's all on my end". AKA, "That's all I have from my side of the conversation"
