Many firms and corporations are concerned about the protection of the personal data of their employees or relatives. Loss of such information may result in financial or customer problems. However, few are concerned about data protection issues for minors. Now they limit the possibility of registration on gaming platforms for those under the age of 14 or 18, cinema services, various forums, social networks, but at the same time, when registering on educational platforms, personal data can be required and not protected from strangers. The amount of personal data processed by one state budget institution covers personal contact information of at least 700-800 students, and for each of them one or two legal representatives. That is, by gaining access to one of the digital platforms for learning or parental performance monitoring (diary.ru), you can get a huge database of contacts of minors and their legal representatives for various purposes, the most harmless of which is spam or advertising.
