  1. Processing data from your devices

(1) In addition to the above-mentioned data, we use technical tools for various functions when you use our website, in particular cookies that can be stored on your device. When you visit our website and at any time thereafter, you have the choice of whether to generally allow cookies to be set or which individual additional functions you would like to select. You can make changes in your browser settings or via our consent manager. Below, we first describe cookies from a technical perspective before going into more detail about your individual options by describing technically necessary cookies and cookies that you can voluntarily select or deselect.

(2) Cookies are text files or pieces of information in a database that are stored on your hard drive and assigned to the browser you are using, so that certain information can be sent to the entity that sets the cookie. Cookies cannot execute programs or transfer viruses to your computer, but primarily serve to make the Internet offering faster and more user-friendly. This website uses the following types of cookies, the functionality and legal basis of which we will explain below:

– Transient cookies: These cookies, in particular session cookies, are automatically deleted when you close your browser or log out. They contain a so-called session ID. This allows various requests from your browser to be assigned to the shared session and your computer can be recognized when you return to our website.

– Persistent cookies: These are automatically deleted after a specified period of time, which varies depending on the cookie. You can view the cookies that have been set and their lifespans at any time in your browser settings and delete the cookies manually.

(3) Mandatory functions technically necessary for displaying the website: The technical structure of the website requires us to use technologies, in particular cookies. Without these technologies, our website cannot be displayed (completely correctly) or the support functions may not be available. These are generally transient cookies that are deleted at the end of your website visit, at the latest when you close your browser. You cannot deselect these cookies if you want to use our website. The individual cookies can be viewed in the consent manager. The use of these cookies is based on § 25 (2) No. 2 TDDDG and Art. 6 (1) (f) GDPR.

(4) Optional cookies with your consent: We only set various cookies with your consent, which you can select on your first visit to our website using the cookie consent tool. The functions are only activated if you give your consent and can be used in particular to enable us to analyze and improve visits to our website, to make it easier for you to use different browsers or end devices, to recognize you when you visit, or to display advertising (including, where applicable, to tailor advertising to your interests, to measure the effectiveness of ads, or to display interest-based advertising). The legal basis for data processing is your consent in accordance with § 25 (1) TDDDG and Art. 6 (1) (a) GDPR. You can revoke your consent at any time without affecting the lawfulness of the processing until revocation.

  1. Consent Manager

To manage your consent, we use the “CCM19” service provided by Papoo Software & Media GmbH. The service sets a cookie within the meaning of Section 3 (3) of this privacy policy, which is necessary for storing and verifying your consent status. Data processing is based on our legitimate interest in managing the cookies and similar technologies used and the related consents in accordance with Art. 6 (1) (f) GDPR and § 25 (2) No. 2 TDDDG.

  1. Matomo

Our website uses the Matomo service provided by InnoCraft Limited. Matomo is an open-source software tool for web analysis. Web analysis involves the collection, gathering, and evaluation of data on the behavior of visitors to websites. A web analysis tool collects data on, among other things, which website a data subject came from (known as the referrer), which subpages of the website were accessed, how often a subpage was viewed, and how long it was viewed for. 

The controller uses the data and information obtained to evaluate the use of this website, to compile online reports showing the activities on our websites, to optimize a website, and to perform a cost-benefit analysis of internet advertising.

Matomo places a cookie on the information technology system of the data subject. What cookies are has already been explained above. Placing the cookie enables us to analyze the use of our website. Each time one of the individual pages of this website is accessed, the Internet browser on the information technology system of the data subject is automatically prompted by the Matomo component to transmit data to our server for the purpose of online analysis. As part of this technical process, we receive information about personal data, such as the IP address of the data subject, which we use, among other things, to track the origin of visitors and clicks.

Matomo is hosted by us on the web server; no data is transferred to the provider of the tool or other third parties.

The legal basis for data processing is § 25 (1) TDDDG in conjunction with Art. 6 (1) (a) GDPR. You grant us the necessary consent via the consent given in the Cookie Consent Manager, if applicable.

Further information about Matomo can be found at the following link: https://matomo.org/privacy/

  1. Contact form

When you contact us via the contact form, we will store the data you provide (your email address, your name and telephone number, if applicable) in order to answer your questions. 

This data is processed on the basis of Art. 6 (1) (b) GDPR, provided that your request 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 inquiries addressed to us in accordance with Art. 6 (1) (f) GDPR or on your consent in accordance with Art. 6 (1) (a) GDPR, if this has been requested.

The contact details will remain with us until you request us to delete them, revoke your consent to their storage, or the purpose for data storage no longer applies (e.g., after your request has been processed or a purchase contract has been concluded). Mandatory legal provisions—in particular retention periods—remain unaffected.

  1. Social Media

LinkedIn: Social network; Service provider: LinkedIn Ireland Unlimited Company, Wilton Place, Dublin 2, Ireland;

Privacy policy: https://www.linkedin.com/legal/privacy-policy Standard contractual clauses: https://legal.linkedin.com/dpa

Opt-out option: https://www.linkedin.com/psettings/guest-controls/retargeting-opt-out

Data processing agreement: https://legal.linkedin.com/dpa

The regulations governing the internal processing of Page Insights at LinkedIn can be found at https://legal.linkedin.com/pages-joint-controller-addendum.

Data subjects can assert their rights with LinkedIn and with us, but LinkedIn has primary responsibility for the processing of Insights data in accordance with the GDPR.

We do not make any decisions regarding the processing of Insights data and all other information resulting from Art. 13 GDPR, including the legal basis, identity of the controller, and storage period of cookies on user devices. LinkedIn fulfills all obligations under the GDPR with regard to the processing of Insights data. 

We use the technical platform and services of the provider for these information services. We would like to point out that you use our social media platforms and their functions at your own risk. This applies in particular to the use of interactive functions (e.g., commenting, sharing, rating). When you visit our pages, the providers of the social media platforms collect, among other things, your IP address and other information stored on your device in the form of cookies. This information is used to provide us, as the operators of the accounts, with statistical information about your interaction with us.

The data collected about you in this context is processed by the platforms and may be transferred to countries outside the European Union, in particular the USA. An adequacy decision is in force between the EU and the USA, confirming the permissibility of data transfer. According to their own statements, all of the aforementioned providers maintain an adequate level of data protection that corresponds to the former Privacy Shield. LinkedIn has certified itself under the EU-U.S. Data Privacy Framework.

We do not know in detail how these platforms use the data from your visit to our account and interaction with our posts for their own purposes, how long this data is stored, and whether data is passed on to third parties. Data processing may differ depending on whether you are registered and logged in to the social network or visit the site as an unregistered and/or unlogged-in user. When you access a post or the account, the IP address assigned to your device is transmitted to the provider of the social media platform. If you are currently logged in as a user, a cookie on your device can be used to track how you have moved around the network. Buttons embedded in websites enable the platforms to record your visits to these websites and assign them to your respective profile. This data can be used to tailor content or advertising to you. If you want to avoid this, you should log out or deactivate the “stay logged in” function, delete the cookies on your device, and restart your browser.

Furthermore, we only process the data from your use of our service that you provide to us and that requires interaction. For example, if you ask a question that we can only answer by email, we will store your information in accordance with the general principles of our data processing, which we describe in this privacy policy. 

  1. Your data protection rights

(1) You have the following rights vis-à-vis a controller with regard to personal data concerning you:

– Right to information,

  1. Objection to the processing of your data or withdrawal of your consent

(1) If you have given your consent to the processing of your data, you can withdraw this consent at any time by contacting Buchholz Hydraulik GmbH, Wasserwerksweg 1-3, 24222 Schwentinental, Germany by mail or by email to info@buchholz-hydraulik.de. Such withdrawal affects the lawfulness of the processing of your personal data after you have notified us of your withdrawal. The lawfulness of the processing of your data up to the time of your withdrawal remains unaffected. 

(2) Insofar as we base the processing of your personal data on our legitimate interests, you can object to the processing. This is the case if the processing is not necessary in particular for the fulfillment of a contract with you, which is described by us in the following description of the functions. When exercising such an objection, we ask you to explain the reasons why we should not process your personal data as we have done. In the event of your objection, we will examine the situation and either stop or adjust the data processing or point out to you our compelling legitimate reasons for continuing the processing.
