Researchers have responsibilities after a project is completed (Kara 2018). It is not easy to define the end of a research project: is it when the funding has all been spent, or when the last meeting has been held, or the last output published? Whenever the end point is, researchers continue to be responsible for participants’ welfare. This includes helping them when necessary and relevant to the research: for example, if a participant requests amendment to, or removal of, a digitally published output years or decades later. Researchers must ensure that data are stored appropriately and that, as far as possible, findings are taken up and used [see also Application]. Researchers also have responsibilities for their own self-care (see Safety)
