SafetyNet is fun for the whole family! By playing the quiz, you learn about security, behavior on the Internet, social networks and other current topics. In order to encourage even the youngest to participate in the race of knowledge, we adapted the materials to the age of 5th to 8th grade of elementary school. We encourage parents to play the quiz together with their children, deepening their knowledge about safety on the ubiquitous Internet.By updating the material through an advanced knowledge quiz and new educational content with adaptation for playing on smartphones, the possibility of greater use is ensured for both high school students and their parents. We encourage parents to play the quiz together with their children, deepening their knowledge about safety on the ubiquitous Internet.For those who want to know more, we have also included learning materials, and for parents we have prepared a corner where they can find content already published on the Internet that tells more about a particular topic.The project was created on the initiative of the Split-Dalmatia Police Administration, with the cooperation of the Faculty of Electrical Engineering, Mechanical Engineering and Shipbuilding in Split and members of the DUMP Association of Young Developers with the support of the city of Split. It is based solely on the goodwill of the volunteers who worked on it.
