The preschoolers from Polish and Greek kindergartens participated in the activities planned according to the project's schedule established by the teachers. The children were asked about their participation in the project and all of them agreed. 

Taking care about data protection and copyright issues:

• the teachers used RODO regulations to provide a framework to ensure that personal information about kids is shared appropriately;
• the teachers considered safety and wellbeing of their pupils. They shared the most necessary informations for the project's purpose, they used only names without surnames of preschoolers;
• the teachers during publication photos from events, online meetings covered their faces with funny filters;
• the parents were informed about their kids' participation and different ways of children's educational activation - every child has been given access to view Twinspace activities with their parents by adding them as the members;
• the teachers were open and honest with their parents from the outset about why, what, how and with whom information will, or could be shared, and seek their agreement.
