Librus is a set of Polish IT systems supporting education, including an electronic school register and communication between schools, pupils and parents. The privacy policy names the systems Synergia, e-Sekretariat, e-Świadectwa, e-Biblioteka, OSIN and Nasze Szkoły. The service is offered online, with user accounts and mobile apps.
The operator is Librus sp. z o.o., a Polish company with its seat in Katowice. For school systems the school is the controller and Librus the processor. The privacy policy names no data centre and commits only on a best-efforts basis to keep processing in Poland. According to the policy, some data may be transferred to servers outside the EEA, mainly in the United States, through providers such as Cloudflare. The owners were not established from the sources consulted. For a European organisation the provider is established in the EU, but the transfers to US servers call for attention.
