There are many day-to-day activities that take place within the framework of ICT research (conducting surveys, creating websites, organizing conferences…). Without them it would be extremely difficult to develop an activity of this type. Each of them involves multiple and complex problems related to data protection. This chapter introduces the fundamental guidelines that researchers and innovators should follow to ensure adequate compliance with the regulations in force. The recommendations developed do not intend to be exhaustive nor do they allow us to enter into each and every detail of the activities to which they refer. Those who develop them should be sure of the particularities that their own national systems may present. In case of doubt, it is always better to have the help of a DPO or legal advisor who can advise on the issue at stake.
