VULCAN (Dziennik Vulcan): sovereignty score and 8 European alternatives

VULCAN is a Polish electronic grade book, known as Dziennik Vulcan (e-dziennik), which is used through the eduVulcan mobile app among other channels. The range also includes products such as UONET+ and Prawo Optivum. The system is developed by VULCAN sp. z o.o., a Polish software company that Wikipedia says was founded in 1988. The vendor's pages that could be reached contained little product information, so the functions described here are limited to what the sources consulted report.

VULCAN sp. z o.o. has its head office in Wrocław. According to Wikipedia, the company has been owned by Nowa Era sp. z o.o. since a buy-out in May 2006. The owner's country is not confirmed in the sources consulted, and no foreign parent company has been identified. The website does not state where school data is hosted, and no GDPR or RODO statement was found on the pages consulted. A European school processing pupil data should therefore ask the vendor directly for the hosting location and the data processing agreement.
