Controller - the natural or legal person, public authority, agency, or other body that alone or together with other bodies determines the purposes and means of the processing of personal data, the entity that decides how and why the personal data are processed. It has the main responsibility for compliance with applicable data protection laws.

Supervisory authority - an independent public authority that has the legal task of overseeing compliance with applicable data protection laws.

Personal data - Personal data are all data relating to a natural person whose identity has been determined or can be determined based on them.

Processing means anything that is done with any personal data, whether automated or not, such as: collection, recording, organization, structuring, storage, adaptation or modification, downloading, consultation, use, disclosure by transmission, dissemination or making available in any way, by alignment or combination, restriction, erasure, or destruction.

Processor is a natural or legal person, public authority, agency, or other body that processes personal data on behalf of the controller.

Anonymization: Irreversibly de-identifying personal information so that the person cannot be identified using reasonable time, cost, and technology either by the controller or any other person. The principles of personal data processing do not apply to anonymous data because they are no longer personal data.

Pseudonymization: The processing of personal data in such a way that the personal data can no longer be attributed to a particular data subject without the use of additional information, provided that such additional data are kept separately and are subject to technical and organizational measures to ensure that they are not attributed to any natural person. Pseudonymization reduces, but does not completely remove, the possibility of linking personal data with the data subject. Since pseudonymized data are still personal data, the processing of pseudonymized data should comply with the principles of personal data processing.
