C.2 Data collection on this website

C.2.1 Use of cookies

We use so-called "cookies". Cookies are small data packets that are temporarily stored on your terminal device when you visit this website. They contain, for example, information about the language, page settings, your e-mail address and your name (when you log in).

Cookies have various functions. Numerous cookies are technically necessary, as certain website functions are not available without them (e.g. the shopping basket function or the display of videos). Other cookies are used to evaluate user behaviour or display advertising.

Cookies are either stored temporarily for the duration of a session (session cookies) or permanently (permanent cookies) on your device. Session cookies are automatically deleted at the end of your visit. Permanent cookies remain stored on your device until you delete them yourself or your web browser automatically deletes them.

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

Cookies that are necessary for the electronic communication process, for the provision of certain functions you have requested (e.g. for the shopping basket function) or for the optimisation of the website (e.g. cookies for measuring the web audience) (necessary cookies) are stored on the basis of Art. 6 para. 1 lit. f GDPR (overriding legitimate interest), unless another legal basis is specified.

We have a legitimate interest in storing necessary cookies for the technically error-free and optimised provision of our services. If consent to the storage of cookies and similar recognition technologies has been requested, processing is carried out exclusively on the basis of this consent (Art. 6para. 1 lit. a GDPR and Sec. 25 para.1 TDDDG); consent can be revoked at any time.

You can set your browser to notify you when cookies are set. This allows you to allow cookies in individual cases or for certain cases, or to generally exclude them, as well as to activate the automatic deletion of cookies when you close your browser. If you deactivate cookies, the functionality of this website may be limited.

If cookies from third-party companies or for analysis purposes are used, we will inform you separately in this privacy policy and, if necessary, ask for your consent.

You can edit your cookie settings here: Go to the german data protection site and you can find the cookie button right on top of the page.

C.2.2 Cookie consent with Cookiebot

Our website uses Cookiebot's consent technology to obtain your consent to store certain cookies on your device or to use certain technologies and to document this in accordance with data protection regulations. This technology is provided by Usercentrics A/S, Havnegade 39, 1058 Copenhagen, Denmark (hereinafter "Cookiebot").

When you visit our website, a connection is established to Cookiebot's servers in order to obtain your consent and other declarations regarding the use of cookies. Cookiebot then stores a cookie in your browser to assign the consents given or their revocation. The data collected in this way is stored until you request us to delete it, delete the Cookiebot cookie yourself or the purpose for data storage no longer applies. Mandatory legal retention obligations remain unaffected.

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

C.2.3 Server log files

Our website provider automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. These are:

  • browser type and browser version,

  • Operating system used,

  • referrer URL,

  • Host name of the accessing computer,

  • Time of the server request,

  • IP address.

This data is not merged with other data sources.

This data is collected on the basis of Art. 6 para. 1 lit. f GDPR (overriding legitimate interest). We have a legitimate interest in the technically error-free presentation and optimisation of our website – for this purpose, the server log files must be collected.

C.2.4 Contact form

If you send us enquiries via the contact form, your details from the enquiry form, including the contact details you provided there, will be stored by us for the purpose of processing the enquiry and in the event of follow-up questions.

This data is processed on the basis of Art. 6 para. 1 lit. b GDPR, provided that your enquiry is related to the performance of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, processing is based on our legitimate interest in the effective processing of enquiries addressed to us (Art. 6para. 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.

The data you enter in the contact form will remain with us until you request us to delete it, revoke your consent to its storage, or the purpose for data storage no longer applies (e.g. after your enquiry has been processed). Mandatory legal provisions – in particular retention periods – remain unaffected.

When processing enquiries and complaints that you send us via the contact form, this data may be forwarded to the departments responsible for handling the respective issues and questions. These responsible departments are primarily other transport companies in the Hamburg Transport Association (hereinafter „hvv“), which have provided the transport service or are responsible for certain sales channels and the operation of infrastructure. The same applies to mobility service providers whose services are made available via hvv switch, or to the payment service providers used. Depending on the content of an enquiry or complaint, it may also be forwarded to other departments. This applies in particular to the affiliated companies associated with HOCHBAHN, but also to external companies such as Stadtreinigung Hamburg (Hamburg City Cleaning) or the relevant authorities. Forwarding only takes place to the extent that it is necessary and appropriate for processing the request. We base such forwarding to other competent bodies for the purpose of processing enquiries and complaints on an overriding legitimate interest on our part (Art. 6 para. 1 lit f GDPR). Forwarding enables the quick and comprehensive processing of the matter in question by the body that also has the information required for processing. It relieves you, the customer, of the need to find out in advance about the distributed responsibilities within hvv, in the hvv switch environment or within the HOCHBAHN shareholding structure. We do not see any conflicting overriding legitimate interest, as the enquiries and complaints in question are submitted to us precisely with the aim and desire that they be processed by the responsible body.

C.2.5 Form for reporting illegal parking, littering and damage at hvv switch points

If you send us information about illegal parking at hvv switch points using the reporting form, your details, including your first and last name and your email address, will be recorded for the purpose of reporting and processing the illegal parking. Your personal data will not be stored by HOCHBAHN, but will be forwarded to our parking space monitoring service provider (PRS Parkraum Service GmbH, Kirchplatz 7, 58739 Wickede (Ruhr); hereinafter referred to as PRS) when you submit the form and will be processed there. Only the photo of the illegally parked vehicle will be stored by HOCHBAHN for a period of three months for the purpose of preserving evidence and will then be deleted (statute of limitations according to Section 26 para.3 of the Straßenverkehrsgesetz (Road Traffic Act). Information on data protection and the handling of your personal data at PRS can be found in their privacy policy.

If you send us information about dirt or damage at hvv switch points, you have the option of providing your name and email address. This information is voluntary. This data is processed by HOCHBAHN. The data you provide will be used exclusively for the purpose of processing your report. If you have provided your name and email address, this information will be deleted immediately after the necessary measures to remove the dirt or repair the damage have been completed. If you decide to report anonymously at , no personal data will be stored.

In principle, the information provided on the forms and your personal data are voluntary. We base the processing on Art. 6 para. 1 lit. f GDPR (overriding legitimate interest). We have a legitimate interest in eliminating contractual disruptions (illegal parking) as well as dirt and damage at hvv switch points and in making the available car-sharing parking spaces available to our hvv switch customers in the best possible condition. Due to the voluntary nature of your report, we do not see any legitimate interest on your part that conflicts with or outweighs our legitimate interest.

We use ProcessWire, a content management system (CMS), to display the forms described here. By using ProcessWire, we process certain personal data in order to provide you with a user-friendly and personalised online experience. The personal data processed by ProcessWire is used for the purpose of providing and maintaining our website. This includes displaying content and improving website functionality. ProcessWire enables us to process data such as IP addresses, browser information and, if provided, personal data such as your name and email address, which you have provided to us, for example, via the contact form provided. The processing of your data by ProcessWire is based on our legitimate interest in the efficient provision and maintenance of the functions of our website (Art. 6 para. 1 lit. f GDPR) and, where applicable, on the basis of your consent, which you have given us, for example, for the use of cookies (Art. 6 para. 1 lit. a GDPR and Sec. 25 para. 1 TDDDG).

C.3 Plugins and tools

C.3.1 YouTube with enhanced data protection

This website embeds videos from the YouTube website. The operator of the site 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 this website before they watch the video. However, the extended data protection mode does not necessarily exclude the transfer of data to YouTube partners. 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 YouTube's servers is established. This tells the YouTube server which of our pages you have visited. If you are logged into your YouTube account, YouTube allows you to associate your surfing behaviour directly with your personal profile. You can prevent this by logging out of your YouTube account.

Furthermore, after starting a video, YouTube may store various cookies on your device 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 collect video statistics, improve user-friendliness and prevent fraud attempts.

After starting a YouTube video, further data processing operations may be triggered over which we have no control.

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

C.4.5 Meta Pixel

We use Meta's visitor action pixel to measure conversions. This service is provided by Meta Platforms Ireland Limited, Merrion Road, Dublin 4, D04 X2K5, Ireland (hereinafter "Meta"). However, according to Meta, the data collected is also transferred to the United States and other third countries.

This allows the behaviour of our website visitors to be tracked after they have been redirected to our website by clicking on a Meta advertisement. This enables the effectiveness of Meta advertisements to be evaluated for statistical and market research purposes and future advertising measures to be optimised.

The data collected is anonymous to us as the operator of this website; we cannot draw any conclusions about the identity of the users. However, the data is stored and processed by Meta, so that a connection to the respective user profile on Facebook or Instagram is possible and Meta can use the data for its own advertising purposes in accordance with the Meta Data Use Policy (https://www.facebook.com/about/privacy/). This enables Meta to place advertisements on Facebook or Instagram pages and other advertising channels. As the website operator, we have no influence over this use of the data.

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

Insofar as personal data is collected on our website with the help of the tool described here and forwarded to Meta, we and Meta are jointly responsible for this data processing (Art. 26 GDPR). Joint responsibility is limited exclusively to the collection of data and its transfer to Meta. The processing by Meta after the transfer is not part of the joint responsibility. Our joint obligations have been set out in a joint processing agreement. The wording of the agreement can be found at: https://www.facebook.com/legal/controller_addendum. According to this agreement, we are responsible for providing data protection information when using the Meta tool and for the data protection-compliant implementation of the tool on our website. Meta is responsible for the data security of Meta products. You can assert your rights as a data subject (e.g. requests for information) regarding the data processed by Facebook or Instagram directly with Meta. If you assert your rights as a data subject with us, we are obliged to forward them to Meta.

Data transfer to the USA is based on the standard contractual clauses of the EU Commission. Details can be found at:

We use the services of The UK Trade Desk Ltd., 1 Bartholomew Close, London, EC1A 7BL, United Kingdom (hereinafter "Trade Desk"), as a demand-side platform (DSP) to run digital advertising campaigns on various channels (web, apps, audio, connected TV), measure their success and optimise their delivery. In addition, the platform is used for device/household mapping to ensure consistent delivery. Other purposes include limiting ad frequency, fraud detection and reporting.

When using the platform, cookie IDs, IP addresses, device and browser information, usage and event data, timestamps and referrers are processed in particular.

This data is hashed or tokenised so that it cannot be traced back. The identifier is used for cross-channel addressability.

Trade Desk cookies are set and read exclusively on the basis of your consent in accordance with Sec. 25 para. 1 TTDSG in conjunction with Art. 6 para. 1 lit. a GDPR. These technologies will not be activated without your consent. The further processing of data by us for marketing and optimisation purposes is also based on Art. 6 para. 1lit. a GDPR.

D. hvv switch on social networks

We maintain publicly accessible profiles on social networks.

This section of the privacy policy applies to the following social media sites where we provide information about hvv switch:

Detailed information on the individual social networks we use can be found below.

D.1 Data processing by social networks

Social networks can usually analyse your usage behaviour 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 sites triggers numerous data processing operations relevant to data protection, which are described below.

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 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 is carried out, for example, via cookies stored on your 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 preferences and interests are stored. In this way, interest-based advertising can be displayed to you both within and outside the respective social media presence. If you have an account with the respective social network, interest-based advertising can be displayed to you on all devices on which you are or have been logged in.

Please note that we cannot track all processing operations on 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 privacy policies of the respective social media portals.

D.1.1 Legal basis

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

D.1.2 Responsible parties and assertion of rights

When you visit one of our social media sites (e.g. Facebook), 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, correction, deletion, restriction of processing, data portability and complaint) both against us and against the operators of the respective social media portal (e.g. Facebook).

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 corporate policy of the respective provider.

E. Customer service enquiries

If you contact us by e-mail, telephone or fax, your enquiry, including all resulting personal data (name, enquiry), will be stored and processed by us for the purpose of processing your request.

This data is processed on the basis of Art. 6 para. 1 lit. b GDPR, provided that your enquiry is related to the performance of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, processing is based on our legitimate interest in the effective processing of 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.

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

When processing enquiries and complaints that you send us, this data may be forwarded to the departments responsible for handling the respective issues and questions. These responsible departments are primarily other transport companies in the hvv that have provided the transport service or are responsible for certain sales channels and the operation of infrastructure. The same applies to mobility service providers whose services are made available via hvv switch, or to the payment service providers used. Depending on the content of an enquiry or complaint, it may also be forwarded to other departments. This applies in particular to the affiliated companies associated with HOCHBAHN, but also to external companies such as Stadtreinigung Hamburg (Hamburg City Cleaning) or the relevant authorities. Forwarding only takes place to the extent that it is necessary and appropriate for processing the request. We base such forwarding to other competent bodies for the purpose of processing enquiries and complaints on an overriding legitimate interest on our part (Art. 6 para. 1 lit. f GDPR). Forwarding enables the quick and comprehensive processing of the matter in question by the body that also has the information required for processing. It relieves you, the customer, of the need to find out in advance about the distributed responsibilities within hvv, in the hvv switch environment or within the HOCHBAHN shareholding structure. We do not see any conflicting overriding legitimate interest, as the enquiries and complaints in question are submitted to us precisely with the aim and desire that they be processed by the responsible body.

F. EU-U.S. Data Privacy Framework

We also use service providers who are certified under 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 United States that aims to ensure compliance with European data protection standards when data is processed in the United States. Every company certified under the EU-U.S. DPF undertakes to comply with these data protection standards. Further information on this can be found at the following link: https://www.dataprivacyframework.gov/.

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

G. Storage period

Unless a specific storage period is specified in this privacy policy, your personal data will remain with us until the purpose for data processing no longer applies. If you assert a legitimate request for deletion or revoke your consent to data processing, your data will be deleted unless we have other legally permissible reasons for storing your personal data (e.g. tax or commercial law retention periods). If there are legally permissible reasons, the deletion will take place after these reasons no longer apply.

H. Data protection rights

The GDPR grants certain rights to data subjects whose personal data is processed by us, which we would like to explain to you here. If you have any questions about this or other data protection issues at hvv switch, please feel free to contact us as the controller or our data protection officer. You will find the contact details in section A.

H.1 Information, deletion and correction

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 the processing, the category of data used, its recipients and the planned duration of data storage or the criteria for determining this duration. Furthermore, you have the right to have the data deleted and/or corrected, in particular if the data is incomplete or incorrect, is no longer necessary for the purpose for which it was collected, or if you have revoked your consent to its processing.

H.2 Withdrawal of consent

If data processing is carried out with your consent, you can revoke this consent 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.

H.3 Right to object

If 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. This requires reasons arising from your particular situation (Art. 21para. 1 GDPR).

H.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 usually need time to verify this. For the duration of the verification, you have the right to request the restriction of the processing of your personal data.

  • If the processing of your personal data was or is unlawful, you can request the restriction of data processing instead of erasure.

  • If we no longer need your personal data, but you need it to exercise, defend or assert 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 pursuant to Art. 21para. 1 GDPR, a balance must be struck between your interests and ours. As long as it is not yet clear whose interests prevail, you have the right to request the restriction of the processing of your personal data.

H.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 be done if it is technically feasible.

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

If you believe that we are violating data protection law, you have the right to lodge a complaint with a supervisory authority. The right to lodge a complaint exists without prejudice to other administrative or judicial remedies . In Hamburg, you can contact the competent supervisory authority at: Hamburger Beauftragter für Datenschutz und Informationsfreiheit (The Hamburg Commissioner for Data Protection and Freedom of Information), Ludwig-Erhard-Str. 22, 20459 Hamburg, email: mailbox@datenschutz.hamburg.de.
