Privacy Policy

Thank you for your interest in our company. We take data protection very seriously.

In principle, you can use our website without providing any personal data. If a data subject wishes to make use of our company's services via our website, this may require the processing of personal data. If the processing of personal data is necessary and there is no legal basis for such processing, we will always obtain the consent of the data subject.

Personal data (such as the name, address, e-mail address or phone number of a data subject) is always processed in accordance with the General Data Protection Regulation (GDPR) and in line with the applied national provisions on data protection
The following Privacy Policy aims to provide information to the public on the nature, scope and purpose of the personal data we collect, use and process. This Privacy Policy also informs data subjects about their rights.

As the controller, we have implemented numerous technical and organisational measures in order to ensure that the personal data processed via our website is afforded the most complete protection possible. Nevertheless, data transfers via internet can always include security vulnerabilities, meaning that it is impossible to guarantee complete protection all the time. For this reason, any data subject may of course communicate personal data to us by phone, for example, as an alternative.

1. Definition of terms

This Privacy Policy is based on the definitions that have been used by European regulators for the adoption of the GDPR (Article 4 GDPR). This Privacy Policy is intended to be simple to read and easy to understand for everyone. The GDPR can be accessed using the following link:


The aim of our Privacy Policy is to provide you with plain, clear information about the processing of your personal data on our websites and in our apps. Therefore, we explain the following terms, amongst others, which will be used in this Privacy Policy:

  • "Personal data" means any information relating to an identified or identifiable natural person (hereinafter referred to as  "data subject"); an identifiable natural person  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 subject" means each identified or identifiable natural person whose personal data is processed by the controller.

  • "Processing" means any operation or set of operations which is performed on personal data or on sets of personal data, whether or not by automated means, such as collection, recording, organisation, structuring, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment or combination, restriction, erasure or destruction.

  • "Restriction of processing means the marking of stored personal data with the aim of limiting their processing in the future.

  • "Profiling" means any form of automated processing of personal data consisting of the use of personal data to evaluate certain personal aspects relating to a natural person, in particular to analyse or predict aspects concerning natural person's performance at work, economic situation, health, personal preferences, interests, reliability, behaviour, location or movements.

  • "Controller" means the natural or legal person, public authority, agency or other body which, alone or jointly with others, determines the purposes and means of the processing of personal data; where the purposes and means of such processing are determined by Union or member state law, the controller or the specific criteria for its nomination may be provided for by Union or member state law.

  • "Recipient" means a natural or legal person, public authority, agency or another body, to which the personal data is disclosed, whether a third party or not. However, public authorities which may receive personal data in the framework of a particular inquiry in accordance with Union or member state law shall not be regarded as recipients; the processing of this data by those public authorities shall be in compliance with the applicable data protection rules according to the purposes of the processing.

  • "Third party" means a natural or legal person, public authority, agency or body other than the data subject, controller, processor and persons who, under the direct authority of the controller or processor, are authorised to process personal data.

4. Erasure and restriction of processing of personal data

Should the purpose of storage not be fulfilled, or a legally prescribed storage period expire, the personal data is, routinely and in accordance with the statutory provisions, erased or processing thereof is restricted.

5. Collection and storage of personal data and nature and purpose of use

a) If you visit our website

In principle, you can use our website without disclosing your identity. When our website is requested, the browser used on your device automatically sends information to our website's server. This information is temporarily stored in a log file. In the process and without any action on your part, the following information is collected and stored until its automatic erasure:IP address of the computer making the request,

  • Date and time of access,
  • Name and URL of the file requested,
  • Website from which access originated (referrer URL) and
  • The browser used and potentially the operating system of your computer, as well as the name of your access provider.

This data is processed by us for the following purposes:

  • To guarantee that a connection can be established with the site without issue,
  • To guarantee that our website is convenient to use,
  • To assess system security and stability and
  • For further administrative purposes.

The legal basis for this data processing is Article 6(1f) GDPR. Our legitimate interest ensues from the aforementioned purposes of data collection. We do not use the collected data for the purpose of drawing conclusions about you as an individual under any circumstances.

Furthermore, we use cookies and analytical services when you visit our website; you can find more detailed explanations on these under Items 9 and 11 of this Privacy Policy.

b) If you use our contact form

If you have any questions, we provide the option of contacting us using a form made available on our website. It is necessary to provide a valid e-mail address in this instance so that we know who sent the enquiry and are able to respond.

Data is processed for the purpose of getting in touch with us in accordance with Article 6(1a) GDPR, on the basis of your freely given consent.

The personal data we collect for the use of our contact form is automatically erased once your enquiry has been dealt with.

c) If you place orders through our website

You can register as a customer for future orders through our website. The benefit of registering is that you can log into our shop directly, using your e-mail address and password, if you wish to place an order in the future, rather than having to enter your contact details again.

In the process, your personal data is entered into an input screen, transmitted to us and stored. If you place an order through our website, we will initially collect the following data if you register:

  • Title, first name, last name
  • A valid e-mail address
  • Postal address
  • Phone number (landline and/or mobile)
  • Company
  • Country
  • Language
  • Sector
  • Tradesperson status
  • Number of employees

This data is collected in order to:

  • Enable us to identify you as our customer
  • Process, fulfil and transact your order
  • Correspond with you
  • Issue invoices
  • Settle any liability claims that may be brought, and to bring any claims against you
  • Safeguard the technical administration of our website
  • Manage our customer data
  • Enable us to categorise you as our customer in price terms

As part of the order process, we obtain your consent to the processing of this data.

The data is processed following your order and/or registration, and the processing of this data is necessary in accordance with Article 6(1b) GDPR, for the specified purposes, in order to properly process your order and for the mutual fulfilment of obligations arising from the purchase contract.

The personal data we collect in order to process your order is stored until the statutory retention obligation expires and thereafter erased, unless we are obliged to retain the data for longer, in accordance with Article 6(1c) GDPR, on the basis of our retention or documentation obligations under tax or commercial law (arising from the German Commercial Code, German Criminal Code or German Fiscal Code), or if you have consented to a longer storage period in accordance with Article 6(1a) GDPR.

6. Additional information on the legal basis for processing

Article 6(1a) GDPR provides Keller & Kalmbach GmbH with a legal basis for processing operations where consent must be collected for a specific purpose of processing. If the processing of personal data is necessary for the performance of a contract to which the data subject is party, this processing is based on Article 6(1b) GDPR.

The same applies to processing operations necessary for the performance of measures prior to the conclusion of a contract, such as in the case of enquiries concerning our services and products. Should Keller & Kalmbach GmbH be subject to a legal obligation under which it is necessary to process personal data, this processing is based on Article 6(1c) GDPR. In rare cases, it may be necessary to process personal data in order to protect the vital interests of the data subject or of another natural person. In this case, the processing is based on Article 6(1d) GDPR. Furthermore, processing operations may be based on Article 6(1f) GDPR.

This legal basis provides grounds for processing operations not covered by any of the aforementioned legal bases, if the processing is necessary to protect the legitimate interests pursued by Keller & Kalmbach GmbH or by a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject. We are therefore permitted to carry out such processing operations in particular, because they have been specifically referenced by European legislators (see the second sentence of Recital 47 GDPR).

7. Taking legitimate interests into account

Where processing of personal data is based on Article 6(1f) GDPR, the legitimate interest of Keller & Kalmbach GmbH is the execution and fulfilment of our business operations for the benefit of our employees and shareholders.

8. Disclosure of data

We solely disclose your personal data to third parties where these third parties are service partners involved in processing the contract, for example logistics companies tasked with delivery and financial institutions tasked with handling payment matters. In cases where your personal data is disclosed to third parties, the scope of the data transmitted is nevertheless limited to the minimum necessary.

Payment service provider: Adyen

Credit cards are billed by our partner Adyen BV, Simon Carmiggelstraat 6 – 50, 1011 DJ Amsterdam, Netherlands. To prevent and expose cases of fraud, we transmit your IP address to our partner Adyen BV, Simon Carmiggelstraat 6 – 50, 1011 DJ Amsterdam, Netherlands. Your IP address is stored by Adyen BV for this purpose. All data is encrypted before transmission. You can revoke your consent with future effect at any time via the contact details in the Credits and legal section.

Credit assessment

Keller & Kalmbach may collect information concerning your credit rating if you select a payment method (e.g. purchase on account) where Keller & Kalmbach has to provide services in advance.

For these purposes, within the framework of the statutory provisions (in particular the data protection provisions set out in Sections 28a, 28b and 29 of the German Federal Data Protection Act), address and credit rating information is requested from the company CRIF Bürgel Dortmund GmbH & Co. KG and address and credit rating information is also transmitted to CRIF Bürgel Dortmund GmbH & Co. KG for the duration of the customer relationship.

Where there is a legitimate interest in address and credit rating information (particularly for credit assessment purposes), CRIF Bürgel Dortmund GmbH & Co. KG will provide this information, including information determined on the basis of scientifically recognised, mathematical and statistical processes. You can find additional information about CRIF Bürgel Dortmund GmbH & Co. KG and their working method at: www.crifbuergel-dortmund.de

Your personal data is not transmitted to third parties for any purposes besides those specified above.

We also only share your personal data with third parties if:

  • You have provided your express consent in accordance with Article 6(1a) GDPR,
  • Disclosure is necessary in accordance with Article 6(1f) GDPR for the establishment, exercise or defence of legal claims and there is no reason to believe that you have an overriding legitimate interest in the non-disclosure of your data,
  • the event that there is a legal obligation underlying the disclosure in accordance with Article 6(1c) GDPR and
  • This is permitted by law and necessary in accordance with Article 6(1b) GDPR for the fulfilment of the contractual relationship with you.

As part of the order process, we obtain your consent to the disclosure of your data to third parties.

11.1 LinkedIn Ads and conversion tracking

11.1.1 Description and scope of data processing

We place adverts on LinkedIn. We also use the analysis and conversion tracking technology of the LinkedIn platform to check the effectiveness of this advertising. The data processing is carried out by: LinkedIn Ireland, Wilton Plaza, Wilton Place, Dublin 2, Ireland.

LinkedIn places a cookie on your computer from which information is obtained for the display of adverts. The cookie text files contain information about your visits to our website, in particular about the pages you have viewed, in order to be able to make specific product recommendations on subsequent visits to our website or third-party websites. The cookie contains a randomly generated alias. If you visit our website or the LinkedIn website again within a certain period of time, LinkedIn will recognise you through this alias. However, this information cannot be linked to you personally. Neither we nor LinkedIn merge this information with your personal data and do not pass on any personal data to third parties.

11.1.2 Legal basis for data processing

The data processing is based on your consent in accordance with Art. 6 para. 1 sentence 1 lit. a) GDPR.

11.1.3 Purpose of data processing

It is in our interest to inform you about our offer and to make it clear and user-friendly for you. This is also the purpose of data processing.

11.1.4 Duration of data storage

The data will be deleted as soon as it is no longer required for our recording purposes and no legal, contractual or official regulations prevent its deletion.

11.1.5 Possibility of erasure by the data subject

Please note that the setting must be made for all browsers you use. If all your cookies are deleted in a browser, the LinkedIn opt-out cookie will also be affected.

12. Integrating services and content from third parties

Due to our legitimate interests (i.e. interest in the analysis, optimisation and profitable business activity of our online content within the meaning of Article 6(1f) GDPR), we use content and service packages from third parties within this website in order to integrate their content and services, such as videos or fonts (hereinafter referred to as "content").

As a prerequisite to this, the providers of this content must be notified of the user's IP address, as without this IP address the content cannot be sent to the user's browser. Therefore, the IP address is needed to display the content. We endeavour to only use such content from providers who use the IP address for the sole purpose of delivering the content. Furthermore, third-party providers may use pixel tags (invisible graphics also referred to as web beacons) for statistical or marketing purposes.

These pixel tags enable the analysis of information such as visitor traffic to the pages of this website. In addition, the pseudonymised data may be stored in cookies on the user's device and contain, among other data, technical information concerning the browser and operating system, referrer websites, visit duration and other information about the use of our website. This information may also be combined with such information from other sources.

a) AddToAny – bookmarking & sharing

This website uses the service AddToAny to provide the option of sharing content on social networks. Data is only collected if you activate this service yourself. Because you can only use these services if you have a user account with those networks and you have to sign in using your login details, from this point onwards we are no longer responsible; the creation of user accounts, which is to say membership of social media services, requires your consent to the respective privacy policies.

According to their privacy policy, the AddToAny service does not store any personal data (https://www.addtoany.com/privacy) but does use cookies (see above). Furthermore, we do not obtain any data from AddToAny or data resulting from use of the share button. AddToAny provides an opt-out option for a large number of advertising networks. You can opt out directly at optout.networkadvertising.org.
