1.5.2 Integration of YouTube videos
This website embeds videos from the website YouTube. The operator of the website is Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.
We use YouTube in the expanded data protection mode. According to YouTube, this mode ensures that YouTube does not store any information about visitors to this website before they watch the video. Nevertheless, this does not necessarily mean that the sharing of data with YouTube partners can be ruled out as a result of the expanded data protection mode. For instance, regardless of whether you are watching a video, YouTube will always establish a connection with the Google DoubleClick network.
As soon as you start to play a YouTube video on this website, a connection to YouTube’s servers will be established. As a result, the YouTube server will be notified, which of our pages you have visited. If you are logged into your YouTube account while you visit our site, you enable YouTube to directly allocate your browsing patterns to your personal profile. You have the option to prevent this by logging out of your YouTube account.
Furthermore, after you have started to play a video, YouTube will be able to place various cookies on your device or comparable technologies for recognition (e.g. device fingerprinting). In this way YouTube will be able to obtain information about this website’s visitors. Among other things, this information will be used to generate video statistics with the aim of improving the user friendliness of the site and to prevent attempts to commit fraud.

Social networks can usually comprehensively analyse your user behaviour 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 processing operations relevant to data protection. 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 under certain circumstances if you are not logged in or do not have an account with the respective social media portal.

In the following, we inform you about the scope, purpose and use of your personal data collected as part of the application process. We assure you that the collection, processing and use of your data will be carried out in accordance with applicable data protection law and all other statutory provisions and that your data will be treated in strict confidence.
Further information on data protection when registering on the Hamburger Hochbahn AG career portal can be found here:
3.1 Scope and purpose of data collection
If you send us an application, we process your associated personal data (e.g. contact and communication data, application documents, notes in the context of job interviews, etc.) to the extent that this is necessary to decide on the establishment of an employment relationship. The legal basis for this is section 26 BDSG under German law (initiation of an employment relationship), art. 6 para. 1 lit. b GDPR (general contract initiation) and - if you have given your consent - art. 6 para. 1 lit. a GDPR. The consent can be revoked at any time. Your personal data will only be passed on within our company to persons who are involved in processing your application. If the application is successful, the data submitted by you will be stored in our data processing systems based on section 26 BDSG and art. 6 para. 1 lit. b GDPR for the purpose of implementing the employment relationship.
3.2 Registration for the applicant management
You can register for the applicant management service at www.hochbahn.de under the "Careers" section. We use the data entered for this purpose only for the purpose of using this service. The mandatory information requested during registration must be provided in full. Otherwise we will reject the registration.
For important changes, for example in the scope of the offer or in the case of technically necessary changes, we use the e-mail address provided during registration to inform you in this way.
The processing of the data entered during registration is carried out for the purpose of implementing the user relationship established by the registration and, if necessary, for initiating an employment relationship (section 26 BDSG and art. 6 para. 1 lit. b GDPR).
The data collected during registration will be stored by us for as long as you are registered on this website and will then be deleted. Legal retention periods remain unaffected.
3.3 Data retention period
If we are unable to make you a job offer, if you reject a job offer or withdraw your application, we reserve the right to retain the data you have provided 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. This storage serves as evidence in the event of a legal dispute. If it is evident that the data will be required after the 6-month period has expired (e.g. due to an impending or pending legal dispute), the data will only be deleted when the purpose for continued storage no longer applies.
A longer storage can also take place if you have given a corresponding consent (art. 6 para. 1 lit. a GDPR) or if legal storage obligations oppose the deletion.
3.4 Inclusion in the applicant pool
If we do not make you a job offer, it may be possible to include you in our applicant pool. In the event of inclusion, all documents and details from the application will be transferred to the applicant pool to contact you in the event of suitable vacancies.
Inclusion in the applicant pool takes place exclusively based on your express consent (art. 6 para. 1 lit. a GDPR). The provision of consent is voluntary and is not related to the current application process. The person concerned can revoke his/her consent at any time. In this case, the data will be irrevocably deleted from the applicant pool, unless there are legal reasons for retention.
The data from the applicant pool will be irrevocably deleted no later than two years after consent has been given.
4. Video surveillance in the buildings and vehicles of Hamburger Hochbahn AG
An important security measure for the prevention and prosecution of criminal offences is video surveillance in our facilities and vehicles. As a transport company, we have a legitimate interest in ensuring the safety of passengers and employees when using our vehicles and facilities (art. 6 para. 1 lit. f GDPR).
The video surveillance images in our systems and vehicles are recorded on a so-called "ring buffer" for a maximum of 72 operating hours (depending on the vehicle type or system). This means that the data is always automatically overwritten, unless the recording is removed or backed up within the maximum recording period in order to clarify criminal offences or special incidents.
Video data may be shared with police investigating authorities in the context of police investigations.
For the purpose of ensuring operational processes and passenger guidance, anonymous people counts are also automatically collected from live video images. This means that no personal data is collected and processed, only counting events. The collected counting data is used to analyse, forecast and improve overcrowding situations as well as stop and transfer times.
5. News transmission via Telegram or Notify
Via our website, you have the option of ordering the dispatch of disruption and blockage notifications for our four underground railway lines via the messaging services "Telegram" or "Notify". We provide this service via MessengerPeople GmbH, Seidlstrasse 8, 80335 Munich (hereinafter "MessengerPeople") or via Commify Germany GmbH, Radeberger Str. 1, 01099 Dresden, which we have commissioned with the technical implementation of sending the messages.
The messages are sent via a Telegram or Notify account created in our name.

6. Communication with Hamburger Hochbahn AG
6.1 Inquiry by e-mail, telephone or fax
If you contact us by e-mail, telephone or fax, your enquiry including all personal data arising from it (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 processing of this data is based on art. 6 para. 1 lit. b GDPR if your request is related to the performance 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 requests 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.
The data you send to us via contact requests will remain with us until you request us to delete it, revoke your consent to store it or the purpose for storing the data no longer applies (e.g. after processing your request has been completed). Mandatory statutory provisions - in particular statutory retention periods - remain unaffected.
6.2 Chatbot in the career portal
You have the possibility to get individual questions answered quickly via a free chatbot in the career portal of Hamburger Hochbahn AG.
For what purpose do we use the chatbot?
We use the chatbot to answer the questions of 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 request, the chatbot can also send the request directly to the service employee responsible for it. In order to enable a later resumption of the conversation, it is evaluated on the basis of its questions and search criteria when the first contact is made.
What data is needed from them?
When visiting the chatbot, personal data of the user is processed. This includes:
- IP address (will not be stored)
- 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 browsing history. If you want to use the chatbot again after deleting your browsing history, a new randomly generated UserID will be generated. In this case, you may have to re-enter any previously clicked answers or asked questions or inputs. When you use the chatbot again, your browser will send the UserID to the chatbot. 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 they have started are also generated and stored in the events on their browser. To continuously improve the chatbot, we record events such as "chatbot was displayed" and click events such as "user clicked on answer X". For this purpose, we use Conversation IDs, which is generated analogously to the UserID within the bot's database. It serves as an object identifier and is required for the construction of the bot, since database entries need a unique identifier.
Data processing for other purposes (e.g. tracking) does not take place.
What is the legal basis for data processing?
We process your data in accordance with art. 6 para. 1 lit. b of the GDPR. The legal basis for data processing is a gratuitous contract between you and Hamburger Hochbahn AG. In addition, there is a legitimate interest pursuant to 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.
Who gets your data? Where is the data processed?
The chatbot is used within the scope of a commissioned processing according to art. 28 GDPR. The processor is Solvemate GmbH, Friedrichstraße 114, 10117 Berlin, Germany. All data is processed exclusively by certified data center operators within the European Union.
How long will your data be stored?
If the legal basis for data processing ceases to exist, 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.
6.3 Audio and Video Conferencing
For communication purposes, we use online conference tools, among others. The specific 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 conferencing tools collect all data that you provide/enter in order to use the tools (e-mail address and/or your telephone number). Furthermore, the conferencing tools process the duration of the conference, start and end (time) of participation in the conference, number of participants and other "contextual information" related to the communication process (metadata).
Furthermore, the provider of the tool processes all technical data that are necessary for the handling of the 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 speaker and the type of connection. If content is exchanged, uploaded, or otherwise made available within the tool, this is also stored on the servers of the tool providers. Such content includes, in particular, cloud recordings, chat/instant messages, voicemails, uploaded photos and videos, files, whiteboards and other information shared during the use of the service.
Please note that we do not have full influence on the data processing procedures of the tools used. Our options are largely determined by the corporate policy of the respective provider. For further information on data processing by the conference tools, please refer to the data protection statements of the respective 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). Insofar as consent has been requested, the tools in question are used based on this consent; consent can be revoked at any time with effect for the future.
The data collected directly by us via the video and conference tools are deleted from our systems as soon as you request us to delete them, revoke your consent to store them or the purpose for storing the data no longer applies.

We have concluded a contract on order processing (DPA) with the above-mentioned provider. This is a contract required by data protection law, which ensures that the provider only processes the personal data of our website visitors in accordance with our instructions and in compliance with the GDPR.
7. Self-disclosure for visitors of the Hamburger Hochbahn AG
In order that possible chains of infection can be traced by the public health authorities, we may be obliged at times to document the contact details of all visitors to all premises of Hamburger Hochbahn AG. On the basis of prior registrations, an attendance list is kept before the start of the event, in which the date of registration, name, address, telephone number and e-mail address of all visitors are recorded. The data will be collected exclusively for the above-mentioned purpose. The data will be kept for a maximum of four weeks and submitted to the relevant health authority on request. The data is stored in such a way that it is protected from access and inspection by unauthorised third parties. The documentation of the data is carried out within the framework of the Basic Data Protection Regulation (GDPR). Persons who have not registered in advance and are not noted on the attendance list may not be received and are therefore excluded from participation.
The storage and processing of your data is necessary for the fulfilment of a legal obligation (art. 6 para. 1 lit. c GDPR).
We will delete your data no later than four weeks after the end of the event.
The data will be submitted to the responsible health authority upon request. Your data will not be passed on to other or further third parties.
C. What data protection rights do I have?
Upon request, we will gladly inform you whether and which personal data we have stored about you (right to information). In addition, you can correct incorrect data (right to correction) or have such data deleted whose storage is inadmissible or no longer necessary (right to deletion). Under certain circumstances, you may also request us to restrict the processing of your personal data (right to restriction of processing) as well as object to the processing of your data if this processing is based on
- the legal basis of the overriding legitimate interest (art. 6 para. 1 lit. f GDPR) or
- the performance of a task in the public interest (art. 6 para. 1 lit. e GDPR) or
- is based on consent (art. 6 para. 1 lit. a GDPR, right of revocation, if applicable in conjunction with § 25 para. 1 TTDSG).
