B 1581, as the data controller (hereinafter referred to as “our company”), hereby informs you through this document about the principles and procedures for processing your personal data and about your rights in relation to the protection of personal data in accordance with Act No. 110/2019 Coll., on the processing of personal data, as amended (hereinafter referred to as the “Data Processing Act”), and Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data, and repealing Directive 95/46/EC (General Data Protection Regulation; hereinafter “GDPR Regulation”).

Our company is the head of the ČEZ Group and also serves as the main governing entity within the ČEZ Group. We perform this role in accordance with Section 79 of Act No. 90/2012 Coll., on Business Corporations and Cooperatives, also known as the Business Corporations Act (hereinafter “BCA”). The principles and procedures for the processing and protection of personal data, their security, the exercise of your rights as data subjects, including the appointment of the data protection officer, are thus uniformly established for all companies that are part of the ČEZ Group and selected companies of the ČEZ Group.

Mgr. Petr Brázda, LL.M., has been appointed as the Data Protection Officer for the ČEZ Group’s corporate group companies and selected companies within the ČEZ Group.

The information provided here is of a general normative legal nature; it is therefore not part of any contract and may be supplemented with details relevant to specific cases of personal data processing during our mutual communication. 

Our company and its contractual processors process, based on the relevant legal grounds and the purpose of processing, in particular the following categories of your personal data:

1. Identification, authentication, and address data: name, surname, academic title, date of birth, identity document details, permanent and (if applicable) temporary residence address, mailing or other contact address, nationality, place and country of birth, registered business address, company ID, in rare cases personal identification number, handwritten and electronic signature;
2. Contact data: telephone number, email address, data box ID;
3. Electronic data: IP address, cookies, authentication certificates and electronic signature certificates, location data of the user’s device, identifiers on social networks and communication platforms;
4. Other personal data linked to a contractual relationship: bank account number, customer account number, SIPO reference number, access card ID number (if issued to you), login ID and password for a personal user account (if created);
5. In specific cases, special categories of personal data;
6. Personal data in audio recordings – audio recordings;
7. Personal data in visual recordings – CCTV footage, photographs, videos. 

Your personal data may be processed by us manually or automatically; however, in the case of automated processing, we do not use automated decision-making, including profiling, that would affect your rights. 

Our company primarily obtains your personal data directly from you, especially during the contract negotiations and execution; in some cases, we may obtain data from third parties who act as intermediaries in these negotiations. In such situations, we inform you when the provision of personal data is necessary for the performance of a specific service or business cooperation and when it is voluntary but intended to facilitate communication and enhance cooperation between you and our company.

We may also generate additional personal data about you, particularly regarding your consumption and consumer behaviour (e.g., in the supply of commodities such as electricity etc.).

Additionally, we may obtain your personal data from public records or state authorities (e.g., the Trade Register, Land Registry, Insolvency Register, or Central Register of Executions, etc.). Or, we may obtain your personal data from non-public records in specific cases based on applicable law. We only use data obtained from such sources for the purposes for which they were originally published.

To improve the quality of our services, ensure objectivity, verifiability, safety, and the protection of rights, our company monitors and records communication with you (for example, calls with customers). In these cases, you are always informed in advance, and you have the right to object to this method of communication. You can also contact us via our web form: Contact us | ČEZ Group. Special communication lines dedicated exclusively to dealing with crisis and emergency situations are always recorded.

Our company uses camera systems to protect property, personal health, and the safety of services being provided; these cameras are located on buildings owned or managed by our company or another company within the ČEZ Group. You are always informed about the use of camera systems through informational signs placed on the relevant premises. Additionally, you may obtain further information upon request at the reception desks of selected facilities. More details are also available on the website, here. The recorded footage may be provided to administrative authorities or law enforcement agencies if necessary.

The legal title for our processing of the data subject's personal data within the meaning of the GDPR may be the following:

1. Consent to the processing of personal data for one or more specific purposes (Art. 6(1)(a) of the GDPR Regulation);

   Your consent is obtained only in specific cases where the processing of personal data cannot be carried out on the basis of another legal title. In such cases, you will always be informed about the specific purpose, data retention period, and other relevant details regarding your consent. Providing consent is voluntary and may be withdrawn at any time either through the procedure specified for the specific data processing or by contacting the ČEZ Data Protection Officer via GDPR ČEZ (cez.cz).

2. Processing is necessary for the performance of a contract to which the data subject is a party or to take steps at the request of the data subject prior to entering into a contract (Art. 6(1)(b) of the GDPR Regulation);

   In the context of this processing of personal data, you or your representative are a party to the contract being prepared or concluded, i.e. you have access to the content of the contract and, at the same time, to information related to the processing of personal data. If a contract is concluded electronically through a website or app, information about personal data processing for that purpose is provided directly on the site or in the app.

3. Processing is necessary for compliance with a legal obligation to which the controller is subject (Art. 6(1)(c) of the GDPR Regulation);

   Our company is subject to many legal obligations under both Czech and EU law. For greater clarity and better awareness, we present the main applicable legal regulations that determine the areas of personal data processing based on the fulfilment of a legal obligation in the overview of specific purposes attached below.

4. Processing is necessary to protect the vital interests of the data subject or another natural person (Art. 6(1)(d) of the GDPR Regulation);

   This basis is not commonly used in our operations. Such processing of personal data could only occur under exceptional circumstances, of which you would be informed, including further details concerning such potential processing of your personal data.

5. The processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller (Art. 6(1)(e) of the GDPR Regulation);

   This basis is not commonly used in our operations. Such processing of personal data could only occur under exceptional circumstances, of which you would be informed, including further details concerning such potential processing of your personal data.

6. The processing is necessary for the purposes of the legitimate interests pursued by the relevant controller or by a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject which require protection of personal data, in particular where the data subject is a child (Art. 6(1)(f) of the GDPR Regulation).

   The legitimate interest of our company is in particular the ensuring of safety and the protection of the health of individuals and property, keeping of necessary internal records (e.g., lists of qualifications of suppliers' employees working on our premises, overviews of donation requests, etc.), verification of the qualifications of key employees, preparation of contracts with suppliers, customers, and employees, marketing surveys, etc. In all cases of personal data processing based on the legal ground of the legitimate interest of the personal data controller, we conduct a so-called balancing test. We only proceed with the processing of personal data when we have verified through the test that our interests override the interests, rights, and freedoms of the concerned data subjects. During the processing of personal data itself, we always strictly ensure that the interests, rights, and freedoms of data subjects are affected to the least extent possible.

An overview of the specific purposes, legal titles, and periods for which personal data are retained are provided in the table attached. The legal titles marked A–F are defined above.

An overview of Information on the Processing of Personal Data of all companies within the ČEZ Group is available here: Information Memoranda of Group Companies of the ČEZ Group.

GDPR Regulation

Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of individuals with regard to the processing of personal data and on the free movement of such data and repealing Directive 95/46/EC (General Data Protection Regulation).

Personal data (hereinafter referred to as “PD”)

Any information relating to an identified or identifiable natural person; an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier, or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural, or social identity of that natural person.

Data Protection Officer

A person appointed for the entire ČEZ Group and selected companies of the ČEZ Group pursuant to Article 37 of the GDPR Regulation. The Data Protection Officer (hereinafter also referred to as “DPO”) has independent responsibility for the defined area of personal data protection for the ČEZ Group and selected companies of the ČEZ Group and acts as a partner for dealings with the OPDP and data subjects. The responsibility of the Data Protection Officer is, in particular, to protect the interests of data subjects.

Recipient 

A natural or legal person, public authority, agency, or another body to whom personal data is disclosed, whether a third party or not. The recipient has the legal, contractual, or other authority to process personal data. Recipients include other controllers or processors, such as tax, administrative, or regulatory authorities. However, public authorities which may obtain personal data in the context of a specific investigation in accordance with the law of a Member State shall not be regarded as recipients; the processing of such personal data by those public authorities must comply with the applicable data protection rules according to the purposes of the processing.

Data subject (hereinafter referred to as the “DS")

Anatural person to whom the personal data relates. A data subject shall be deemed to be identified or identifiable if their identity is directly or indirectly identifiable on the basis of one or more pieces of personal data.

Proportionality Test

An assessment of a request from the data subject by the Controller, if the request is clearly unfounded or excessive, particularly because it is repetitive. Requests can be considered clearly unfounded, for example, when they are obviously entirely lacking in justification (in cases where justification is necessary) and it is not possible to determine even by interpretation what the data subject is requesting (an example could be an objection to processing under Art. 21(1) GDPR if the DS does not provide information about their situation that would allow the Controller to assess whether the legitimate interest outweighs the interest of the data subject). Requests may be considered clearly excessive, in particular, if they are repeated without justification or are numerous. This cannot be generalized; each case must be assessed in its specific context. The Controller must demonstrate and justify the manifestly unfounded or excessive nature of a request in a communication informing the data subject and the Data Protection Officer of the rejection of the request. The Controller must document and store this justification in case of a possible inspection by the Supervisory Authority.
