In the top left corner, you can notice two labels with icons. These represent an organization and a project. All your data belong to an project and all projects belong to an organization. In many cases, you only have one organization and one project (in the Free plan, you cannot create more).
What is most important are settings of the organization and project. When we click the organization label, we can see the number of users, projects, and the possibility to invite more users, upgrade to a paid plan and general configuration.
Under configuration, we can change organization icon and color, organization code, description and we can set the invoicing contact and upgrade to a paid plan that allows you to have more users, more projects and data.
