I'm new to Trello. Why is there logins for Atlassian and when I click to learn more about privacy, view my profile and visibility it's all on this Atlassian platform? It says I have an Atlassian account and that only me and admins can see my email address? Who are these admins? If I signed up for Trello why is Atlassian showing up everywhere and accessing my information? I'm very confused? Is Atlassian some sort of software tool that controls the selling of trello boards?
