A personal data controller is any entity that determines the purpose and means of personal data processing, performs their collection, processing and storage for the purpose specified by it.
The Data controller is primarily responsible for processing personal data and acts on its own behalf. The basic necessary precondition is the existence of a proper legal reason (basis) for the processing of personal data, which the controller must have in order to be able to process personal data at all. At the same time, it is necessary to sufficiently secure personal data.
