Our Internet pages use so-called "cookies". Cookies are small text files and do not cause any damage to your end device. They are stored on your device either temporarily for the duration of a session (session cookies) or permanently (permanent cookies). Session cookies are automatically deleted at the end of your visit. Permanent cookies remain stored on your end device until you delete them yourself or they are automatically deleted by your web browser.

In some cases, cookies from third-party companies may also be stored on your device when you visit our website (third-party cookies). These enable us or you to use certain services of the third-party company (e.g. cookies for processing payment services).

Cookies have various functions. Many cookies are technically necessary, as certain website functions would not work without them (e.g. displaying videos). Other cookies are used to evaluate the behaviour of users or to display advertising.

Cookies that are required to carry out the electronic communication process (necessary cookies) or to provide certain functions that you have requested (functional cookies) or to optimise the website (e.g. cookies to measure the web audience) are stored on the basis of Art. 6 para. 1 lit. f GDPR, unless another legal basis is specified. The website operator has a legitimate interest in the storage of cookies for the technically error-free and optimised provision of its services.

Mandatory statutory retention obligations remain unaffected.

Usercentrics is used to obtain the legally required consent for the use of certain technologies. The legal basis for this is Art. 6 para. 1 lit. c GDPR.

We have concluded a data processing agreement (DPA) with the above-mentioned provider. This is a contract prescribed by data protection law, which guarantees that the provider will only process the personal data of visitors to our website in accordance with our instructions and in compliance with the GDPR.

This data is collected on the basis of Art. 6 para. 1 lit. f GDPR. The website operator has a legitimate interest in the technically error-free presentation and optimisation of its website - the server log files must be recorded for this purpose.

B.1.6 Use of plugins and tools

B.1.6.1 Integration of Google Maps

This site uses the map service Google Maps. The provider is Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.

To use the functions of Google Maps, it is necessary to save your IP address. This information is usually transmitted to a Google server in the United States and stored there. The provider of this site has no influence on this data transfer. If Google Maps is activated, Google may use Google Fonts for the purpose of standardising the display of fonts. When you call up Google Maps, your browser loads the required web fonts into your browser cache in order to display texts and fonts correctly.

The use of Google Maps is in the interest of an appealing presentation of our online offers and to make it easy to find the places we have indicated on the website. This constitutes a legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR. If a corresponding consent has been requested, the processing is carried out exclusively on the basis of Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TDDDG, insofar as the consent includes the storage of cookies or access to information in your end device (e.g. device fingerprinting) within the meaning of the TDDDG. Consent can be revoked at any time.

Data transfer to the United States is based on the standard contractual clauses of the EU Commission. Details can be found here: https://privacy.google.com/businesses/gdprcontrollerterms/ and https://privacy.google.com/businesses/gdprcontrollerterms/sccs/.

You can find more information on the handling of user data in Google's privacy policy: https://policies.google.com/privacy?hl=en.

Google is certified in accordance with the "EU-U.S. Data Privacy Framework". You can find additional information on this under point C. EU-U.S. Data Privacy Framework.

B.1.6.2 Integration of YouTube videos

This website embeds videos from the YouTube website. The operator of the website is Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.

We use YouTube in extended data protection mode. According to YouTube, this mode means that YouTube does not store any information about visitors to our website before they watch the video. However, the transfer of data to YouTube partners is not necessarily excluded by the extended data protection mode. For example, YouTube establishes a connection to the Google DoubleClick network regardless of whether you watch a video.

As soon as you start a YouTube video on this website, a connection to the YouTube servers is established. This tells the YouTube server which of our pages you have visited. If you are logged into your YouTube account, you enable YouTube to assign your surfing behaviour directly to your personal profile. You can prevent this by logging out of your YouTube account.

Furthermore, YouTube can store various cookies on your end device after starting a video or use comparable recognition technologies (e.g. device fingerprinting). In this way, YouTube can obtain information about visitors to this website. This information is used, among other things, to record video statistics, improve user-friendliness and prevent fraud attempts.

After the start of a YouTube video, further data processing operations may be triggered over which we have no influence.

The use of YouTube is in the interest of an appealing presentation of our online offers. This constitutes a legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR. If a corresponding consent has been requested, the processing is carried out exclusively on the basis of Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TDDDG, insofar as the consent includes the storage of cookies or access to information in your end device (e.g. device fingerprinting) within the meaning of the TDDDG. Consent can be revoked at any time.

Further information about data protection at YouTube can be found in their privacy policy at
https://policies.google.com/privacy?hl=en.

Google is certified in accordance with the "EU-U.S. Data Privacy Framework". You can find additional information on this under point C. EU-U.S. Data Privacy Framework.

B.1.6.3 Authentication with Google reCaptcha

We use Google reCAPTCHA (hereinafter referred to as "reCAPTCHA") on this website for authentication purposes. The provider is Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.

The purpose of reCAPTCHA is to check whether data is being entered on this website by a human or by an automated programme. For this purpose, reCAPTCHA analyses the behaviour of the website visitor based on various characteristics. This analysis begins automatically as soon as our website is accessed. To analyse this, reCAPTCHA evaluates various information (e.g. IP address, time spent on the website or mouse movements made by users). The data collected during the analysis is forwarded to Google.

The reCAPTCHA analyses run completely in the background. When you visit our website, you are not informed that an analysis is taking place.

The data is stored and analysed on the basis of Art. 6 para. 1 lit. f GDPR. We have a legitimate interest in protecting our website from abusive automated spying and SPAM. If a corresponding consent has been requested, the processing is carried out exclusively on the basis of Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TDDDG, insofar as the consent includes the storage of cookies or access to information in your end device (e.g. device fingerprinting) within the meaning of the TDDDG. Consent can be revoked at any time.

For more information about Google reCAPTCHA, please refer to the Google Privacy Policy and the Google Terms of Service at the following links:
https://policies.google.com/privacy?hl=en and
https://policies.google.com/terms?hl=en.

Google is certified in accordance with the "EU-U.S. Data Privacy Framework". You can find additional information on this under point C. EU-U.S. Data Privacy Framework.

B.1.7 Use of analysis tools and advertising

B.1.7.1 Google Tag Manager

We use the Google Tag Manager. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland.

Google Tag Manager is a tool that allows us to integrate tracking or statistical tools and other technologies on our website. The Google Tag Manager itself does not create any user profiles, does not store any cookies and does not carry out any independent analyses. It is only used to manage and display the tools integrated via it. However, Google Tag Manager records your IP address, which may also be transmitted to Google's parent company in the United States.

The Google Tag Manager is used on the basis of Art. 6 para. 1 lit. f GDPR. We have a legitimate interest in the fast and uncomplicated integration and management of various tools on our website. If a corresponding consent has been requested, the processing is carried out exclusively on the basis of Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TDDDG, insofar as the consent includes the storage of cookies or access to information in your end device (e.g. device fingerprinting) within the meaning of the TDDDG. Consent can be revoked at any time.

Google is certified in accordance with the "EU-U.S. Data Privacy Framework". You can find additional information on this under point C. EU-U.S. Data Privacy Framework.

B.1.7.2 Google Analytics

This website uses functions of the web analysis service Google Analytics. The provider is Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.

Google Analytics enables us to analyse the behaviour of visitors to our website. In doing so, we receive various usage data, such as page views, length of visit, operating systems used and origin of the users. This data is assigned to the respective end device of our users. It is not assigned to a user ID.

We can also use Google Analytics to record your mouse and scroll movements and clicks, among other things. Google Analytics also uses various modelling approaches to supplement the recorded data records and uses machine learning technologies for data analysis.

Google Analytics uses technologies that enable the recognition of users for the purpose of analysing their behaviour (e.g. cookies or device fingerprinting). The information collected by Google about the use of this website is usually transferred to a Google server in the United States and stored there.

The use of this service is based on your consent in accordance with Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TDDDG. Consent can be revoked at any time.

The data transfer to the United States is based on the standard contractual clauses of the EU Commission. Details can be found here:

We have concluded an order processing contract with Google and fully implement the strict requirements of the German data protection authorities when using Google Analytics.

B.1.7.3 Google Ads

We use Google Ads. Google Ads is an online advertising programme of Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.

Google Ads enables us to display adverts in the Google search engine or on third-party websites when users enter certain search terms on Google (keyword targeting). Furthermore, targeted adverts can be displayed based on the user data available to Google (e.g. location data and interests) (target group targeting). As the website operator, we can evaluate this data quantitatively, for example by analysing which search terms led to the display of our advertisements and how many advertisements led to corresponding clicks.

The use of this service is based on your consent in accordance with Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TDDDG. Consent can be revoked at any time.

The data transfer to the United States is based on the standard contractual clauses of the EU Commission. Details can be found here:

We use the Deep Media Advertiser Tag, a service provided by Deep Media Technologies GmbH, Hohe Bleichen 8, 20354 Hamburg, Germany. The Deep Media Advertiser Tag is a tag management system for managing technologies for marketing and optimisation purposes. It is used in particular to place adverts that are relevant and interesting for you and to improve campaign performance reports.

When using the advertiser tag, pseudonymised online identifiers, such as cookies and click IDs, may be processed. It is not possible for Deep Media Technologies GmbH to personally identify the user. Data is processed by providers for which the user has given consent in the privacy settings of this website. The collection and storage of data can be cancelled at any time by the respective provider. In the event of an objection, this data will not be passed on to Deep Media Technologies GmbH.

The use of this service is based on your consent in accordance with Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TDDDG. Consent can be revoked at any time.

Further information on the use of data by Deep Media Technologies GmbH can be found here:
https://www.deepmedia.de/en/privacy-information-advertiser-tag/.

B.1.8 Contacting Hamburger Hochbahn AG via our website

You have the option of contacting us via our website (www.hochbahn.de/en). The data protection aspects of these contact options are described here. Data protection information on contacting us outside of our website can be found under point 6 of this privacy policy.

B.1.8.1 Enquiry via contact form

If you send us enquiries via the contact form, your details from the enquiry form, including the contact details you provide there, will be stored by us for the purpose of processing the enquiry and in the event of follow-up questions. We will not pass on this data without your consent.

This data is processed on the basis of Art. 6 para. 1 lit. b GDPR if your enquiry is related to the fulfilment of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, the processing is based on our legitimate interest in the effective processing of the enquiries addressed to us (Art. 6 para. 1 lit. f GDPR) or on your consent (Art. 6 para. 1 lit. a GDPR) if this has been requested; consent can be revoked at any time.

We will retain the data you provide on the contact form until you request its deletion, revoke your consent for its storage, or the purpose for its storage no longer pertains (e.g. after fulfilling your request). Mandatory statutory provisions - in particular retention periods - remain unaffected.

B.1.8.2 Chatbot in the career portal

You have the opportunity to get individual questions answered quickly via a free chatbot in the Hamburger Hochbahn AG career portal.

We use the chatbot to answer questions from interested parties or applicants as quickly as possible. In addition, interested parties or applicants can use digital forms or free input fields in the chatbot to send orders to Hamburger Hochbahn AG for processing. Depending on the content of the enquiry, the chatbot can also send it directly to the relevant service employee. To enable the conversation to be resumed at a later date, it is analysed on the basis of your questions and search criteria when you first make contact.

When visiting the chatbot, the user's personal data is processed. This includes

IP address (is not saved)
UserID
ConversationID
Data entered by the user

The first time you use the chatbot, you will be assigned a randomly generated UserID. The UserID remains stored in your browser until you delete your browser history. If you want to use the chatbot again after deleting your browser history, a new randomly generated UserID will be generated. In this case, you may have to re-enter all previously clicked answers or questions or entries. If you use the chatbot again, the UserID is transmitted to it by your browser. This allows you to continue a previously interrupted conversation, search or input in the chatbot at any time (similar to setting cookies on websites). The conversations, searches or entries you have started are also created and saved in the events on your browser. To continuously improve the chatbot, we record events such as "Chatbot was displayed" and click events such as "User clicked on answer X". To do this, we use conversation IDs, which are generated within the bot's database in the same way as the user ID. It serves as an object identifier and is required for the construction of the bot, as database entries need a unique identifier. Data processing for other purposes (e.g. tracking) does not take place.

We process your data in accordance with Art. 6 para. 1 lit. b GDPR. The legal basis for data processing is a free contract between you and Hamburger Hochbahn AG. In addition, there is a legitimate interest in accordance with Art. 6 para. 1 lit. f GDPR to ensure smooth communication with those interested in our job offers or applicants and to ensure that our services function properly and can be continuously improved.

If the legal basis for data processing ceases to apply, all personal data entered by you will be deleted. Data that is required for contract processing or is subject to statutory retention periods remains unaffected by this.

Order processing

The chatbot is used as part of order processing in accordance with Art. 28 GDPR. The processor is Solvemate GmbH, Friedrichstraße 114, 1011 Berlin, Germany. All data is processed exclusively by certified operators of data centres within the European Union.

B.2 Our social media presence

This privacy policy applies to the following social media sites:

B.2.1 Data processing by social networks

We maintain publicly accessible profiles on social networks. The individual social networks we use are listed below.

Social networks can generally analyse your behaviour as a user comprehensively when you visit their website or a website with integrated social media content (e.g. like buttons or advertising banners). Visiting our social media presences triggers numerous data protection-relevant processing operations. In detail:

If you are logged into your social media account and visit our social media presence, the operator of the social media portal can assign this visit to your user account. However, your personal data may also be collected if you are not logged in or do not have an account with the respective social media portal. In this case, this data collection takes place, for example, via cookies that are stored on your end device or by recording your IP address.

With the help of the data collected in this way, the operators of the social media portals can create user profiles in which your preferences and interests are stored. In this way, interest-based advertising can be displayed to you inside and outside the respective social media presence. If you have an account with the respective social network, the interest-based advertising can be displayed on all devices on which you are logged in or were logged in.

Please also note that we cannot track all processing operations on the social media portals. Depending on the provider, further processing operations may therefore be carried out by the operators of the social media portals. For details, please refer to the terms of use and data protection provisions of the respective social media portals.

B.2.1.1 Legal basis

Our social media presence is intended to ensure the widest possible presence on the Internet. This is a legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR. The analysis processes initiated by the social networks may be based on different legal bases, which must be specified by the operators of the social networks (e.g. consent within the meaning of Art. 6 para. 1 lit. a GDPR).

B.2.1.2 Controller and assertion of rights

If you visit one of our social media sites, we are jointly responsible with the operator of the social media platform for the data processing operations triggered during this visit. You can assert your rights (information, rectification, erasure, restriction of processing, data portability and complaint) both against us and against the operator of the respective social media portal.

Please note that, despite our joint responsibility with the social media portal operators, we do not have full control over the data processing operations of the social media portals. Our options are largely determined by the company policy of the respective provider.

You have the right to receive information about the origin, recipient and purpose of your stored personal data free of charge at any time. You also have the right to object, the right to data portability and the right to lodge a complaint with the competent supervisory authority. Furthermore, you can request the rectification, blocking, erasure and, under certain circumstances, the restriction of the processing of your personal data.

B.2.1.3 Storage period

The data collected directly by us via the social media presence will be deleted from our systems as soon as you ask us to delete it, revoke your consent to storage or the purpose for data storage no longer applies. Stored cookies remain on your end device until you delete them. Mandatory statutory provisions - in particular retention periods - remain unaffected.

We have no influence on the storage period of your data that is stored by the operators of the social networks for their own purposes. For details, please contact the operators of the social networks directly (e.g. in their privacy policy, see below).

A legitimate interest exists, for example, if your data is required for the assertion, exercise or defence of legal claims in the context of the application process (e.g. claims under the “Allgemeines Gleichbehandlungsgesetz” (General Equal Treatment Act)). In the event of a legal dispute, we have an overriding legitimate interest in processing the data for evidence purposes.

If you provide information in your application documents that contains special categories of personal data within the meaning of Art. 9 para. 1 GDPR (e.g. information that allows conclusions to be drawn about your sexual orientation; information about your health; information that allows conclusions to be drawn about your ethnic origin or religion), we will also only process this data to the extent permitted by law.

B.3.2 Registration for application management

You can register for application management at www.hochbahn.de under the "Karriere" section. We only use the data entered for the purpose of using this service. Further information on data protection when registering on the Hamburger Hochbahn AG career portal can be found here:
https://hochbahn.onlyfy.jobs/policy.

B.3.3 Data retention period

If we are unable to make you a job offer, you reject a job offer or withdraw your application, we reserve the right to retain the data you have submitted on the basis of our legitimate interests (Art. 6 para. 1 lit. f GDPR) for up to 6 months from the end of the application process (rejection or withdrawal of the application). The data will then be deleted and the physical application documents destroyed. The retention serves in particular as evidence in the event of a legal dispute. If it is evident that the data will be required after the six-month period has expired (e.g. due to an impending or pending legal dispute), the data will only be deleted when the purpose for further storage no longer applies.

Longer storage may also take place if you have given your consent (Art. 6 para. 1 lit. a and Art. 9 para. 2 lit. a and § 26 para. 2 BDSG or if statutory retention obligations prevent deletion.

B.4 Video surveillance in the buildings and vehicles of Hamburger Hochbahn AG

Video surveillance in our facilities and vehicles is an important security measure for the prevention and prosecution of criminal offences. Video surveillance is used to exercise domiciliary rights, to prevent criminal offences and to assert, exercise or defend legal claims. The legal basis for video surveillance is Art. 6 para. 1 lit. f GDPR, whereby our interests arise from the aforementioned purposes. As a transport company, we also have a legitimate interest in ensuring the safety of passengers and employees when using our vehicles and facilities. Insofar as special categories of personal data are processed, this is done on the basis of Art. 9 para. 2 lit. f in conjunction with Art. 6 para. 1 lit. f GDPR.

The images from video surveillance in our facilities and vehicles are recorded on a so-called ‘ring buffer’ for a maximum of 72 operating hours (depending on the vehicle type or operating facility). This data is therefore constantly and automatically overwritten, unless the recording is removed or secured within the maximum recording period to investigate criminal offences or special incidents.

Video data can be passed on to law enforcement authorities in the event of suspected criminal offences. However, this only happens if there is a legal basis for the transfer. This may be the case in particular if the police or other security authorities take action in the context of so-called danger prevention and demand access to the video surveillance data.

For the purposes of ensuring operational processes and passenger guidance, anonymous people counts are also collected automatically from live video images. This means that no personal data is recorded and processed, only counting events. The counting data collected is used to analyse, forecast and improve overcrowding situations as well as stopping and transfer times.

Via our website, you have the option of ordering the dispatch of disruption and blocking notifications for our four underground lines via the messaging services "Telegram" or "Notify".

B.6 Communication with Hamburger Hochbahn AG

Information on communication with us via our website can be found in section B.1.7 of this privacy policy.

B.6.1 Enquiry by e-mail, telephone or fax

If you contact us by e-mail, telephone or fax, your enquiry including all personal data (name, enquiry) will be stored and processed by us for the purpose of processing your request. We will not pass on this data without your consent.

The data you send to us via contact requests will remain with us until you ask us to delete it, revoke your consent to storage or the purpose for data storage no longer applies (e.g. after your request has been processed). Mandatory statutory provisions - in particular statutory retention periods - remain unaffected.

B.6.2 Audio and video conferencing

We use online conferencing tools, among others, for communication purposes. The individual tools we use are listed below. If you communicate with us by video or audio conference via the internet, your personal data will be collected and processed by us and the provider of the respective conference tool.

The conference tools collect all data that you provide/enter to use the tools (email address and/or your telephone number). The conference tools also process the duration of the conference, the start and end (time) of participation in the conference, the number of participants and other "contextual information" in connection with the communication process (metadata).

Furthermore, the provider of the tool processes all technical data required to handle online communication. This includes, in particular, IP addresses, MAC addresses, device IDs, device type, operating system type and version, client version, camera type, microphone or loudspeaker and the type of connection.

If content is exchanged, uploaded or provided in any other way within the tool, it is also stored on the tool provider's servers. Such content includes, in particular, cloud recordings, chat/instant messages, voicemails, uploaded photos and videos, files, whiteboards and other information shared while using the service.

Please note that we do not have full control over the data processing operations of the tools used. Our options are largely determined by the company policy of the respective provider. Further information on data processing by the conference tools can be found in the data protection declarations of the tools used, which we have listed below this text.

The conference tools are used to communicate with prospective or existing contractual partners or to offer certain services to our customers (Art. 6 para. 1 lit. b GDPR). Furthermore, the use of the tools serves the general simplification and acceleration of communication with us or our company (legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR). If consent has been requested, the tools in question are used on the basis of this consent; consent can be withdrawn at any time with effect for the future.

The data collected directly by us via the video and conference tools will be deleted from our systems as soon as you ask us to delete it, revoke your consent to storage or the purpose for data storage no longer applies. Stored cookies remain on your end device until you delete them. Mandatory statutory retention periods remain unaffected.

We have no influence on the storage period of your data, which is stored by the operators of the conference tools for their own purposes. For details, please contact the operators of the conference tools directly.

We use the following conference tools:

C. EU-U.S. Data Privacy Framework

We also use service providers that are certified in accordance with the "EU-U.S. Data Privacy Framework" (EU-U.S. DPF). The EU-U.S. DPF is an agreement between the European Union and the USA that is intended to ensure compliance with European data protection standards for data processing in the USA. Every company certified under the EU-U.S. DPF undertakes to comply with these data protection standards.

If a company is certified according to the EU-U.S. DPF, the data transfer to the USA is carried out in accordance with Art. 45 GDPR on the basis of an adequacy decision of the European Commission of 10 July 2023. Such an adequacy decision makes it possible to transfer personal data from the EU to the corresponding third country without the need for further transfer instruments or additional measures.

D. Data protection rights

The GDPR grants data subjects whose personal data is processed by us certain rights, which we would like to inform you about here. You are welcome to contact us as the controller or our data protection officer if you have any further questions about data protection at Hamburger Hochbahn AG. You will find the contact details in section A.

D.1 Information, erasure and rectification

You have the right to request information about your personal data stored by us at any time and free of charge. This includes information about the purpose of processing, the category of data used, its recipients and the planned duration of data storage or the criteria for determining this duration. You also have the right to erasure and/or rectification of the data, in particular if the data is incomplete or incorrect, if it is no longer necessary for the purpose for which it was collected or if you have withdrawn your consent to processing.

D.2 Revocation of consent

If the data processing takes place with your consent, you can revoke this at any time. An informal notification by e-mail is sufficient for this purpose. The legality of the data processing operations carried out until the revocation remains unaffected by the revocation.

D.3 Right to object

If the data processing is carried out on the basis of a legitimate interest on our part, you have the right to object to the data processing. The prerequisite for this are reasons arising from your particular situation (Art. 21 para. 1 GDPR).

D.4 Right to restriction of processing

You have the right to request the restriction of the processing of your personal data. The right to restriction of processing exists in the following cases:

If you dispute the accuracy of your personal data stored by us, we generally need time to check this. For the duration of the review, you have the right to request that the processing of your personal data be restricted.
If your personal data has been or is being processed unlawfully, you can request the restriction of data processing instead of erasure.
If we no longer need your personal data, but you need it for the exercise, defence or assertion of legal claims, you have the right to request the restriction of the processing of your personal data instead of its erasure.
If you have lodged an objection in accordance with Art. 21 para.1 GDPR, a balance must be struck between your interests and ours. As long as it has not yet been determined whose interests prevail, you have the right to request the restriction of the processing of your personal data.

D.5 Right to data portability

You have the right to have data that we process automatically on the basis of your consent or in fulfilment of a contract handed over to you or to a third party in a structured, commonly used and machine-readable format. If you request the direct transfer of the data to another controller, this will only take place if it is technically feasible.

D.6 Right to lodge a complaint with a supervisory authority

If you believe that the processing of personal data concerning you is in breach of data protection law, you may - without prejudice to any other administrative or judicial remedy - lodge a complaint with the competent supervisory authority. The competent supervisory authority is
