When you create SciNote account you get one team, within which you then create your projects and manage your data. For this reason, it is not possible to delete your team, since you would not be able to use SciNote.
In this situation, we suggest you rename the team you have created. To rename your team, go to Settings in the upper right corner and open Teams tab. Select the team you have created to preview its information. Continue by clicking on team’s name and a window Edit team name appears. Write the new team name and click the Update button.
