Data Privacy Policy

We, LD DIDACTIC GmbH, Leyboldstr. 1, 50354 Hürth, Germany, (“LD”), take the protection of your personal data very seriously in conjunction with the use of the services under the URL (referred to as “website”).


Which personal data we process depends on how you use the website:

With this data privacy policy, we provide information about the type, scope and purpose of the personal data we collect, use and process. This Data Privacy Policy also explains your rights to you. The following data protection provisions apply to the use of our website and govern the collection, processing and use of the data.


The data is always processed and used in compliance with the General Data Protection Regulation and in accordance with the country-specific data protection provisions applicable to LD.


You can also use the website without providing us or otherwise leaving behind personal data, if you deactivate cookies. Please note that you may not be able to use all of the functions on the website in this case. The website use cookies to present the portfolio, make the website available, for statistical purposes and to analyse the performance of the website.


We do not pass on any personal data to third parties except our order processors in accordance with Art. 28 of the GDPR and our dispatch services.


We are a B2B (business-to-business) provider. That means we only have business relationships with companies, public institutes and public administrations. This is also clearly stated in our General Terms and Conditions. Furthermore, persons under 16 years of age are not permitted to utilise our services.


LD has implemented several technical and organisational measures to handle the processing in order to offer the most consistent protection possible of personal data processed via this website. To protect the security of your data during transmission, we use encryption procedures that meet the current state-of-the-art (i.e. SSL) via HTTPS. Still, Internet-based data transfers can have security gaps, making it impossible to guarantee complete protection. For this reason, you are free to provide us personal information in an alternative manner. For instance, on the telephone.


If you use the services under the URL, you agree to this data protection provision.

What personal data do we collect and how do we use it?

“Personal data” includes all information that pertains to an identified or identifiable natural person. A natural person is considered identifiable if they can be directly or indirectly identified, in particular by means of an assignment of a designation, such as a name, ID number, location data, online ID, or of one or more special characteristics that express the physical, physiological, genetic, psychological, financial, cultural or social identity of this natural person.

Processing includes any procedure executed with or without the help of automated processes or any such series of procedures in conjunction with personal data such as the collection, recording, organisation, sorting, saving, adjustment or modification, reading out, querying, using, disclosure via transmission, distribution or another form of provision, comparison or linking, restriction, deletion or destruction.

Whether and which personal data we collect, process and utilise (collectively referred to as “processing”) depends on how you use our website:


1. Surfing on our website


1.1 Collection of general data and information


LD’s website records a variety of general data and information every time you or an automated system goes to the website. This general data and information is saved in the server’s log files. The following may be recorded: (1) browser types and versions, (2) the operating system used by the accessing system, (3) the website from which an accessing system was referred to our website (referrer), (4) the subpages an accessing system can access on our website, (5) the date and time of the access to the website, (6) an Internet protocol address (IP address), (7) the Internet service provider of the accessing system and (8) other similar data and information that serves to prevent risks in the event of attacks on our IT systems.


When using this general data and information, LD does not draw any conclusions regarding the relevant person. This information is, in fact, required to (1) correctly display the contents of our website, (2) optimise the contents of our website, (3) ensure the continuous functionality of our IT systems and the technology used by our website, and (4) to provide criminal investigative authorities information required for a criminal investigation in the event of a cyber-attack. LD therefore statistically evaluates the data and information collected and evaluates it with the objective of increasing data protection and data security at our company to ultimately ensure the optimum level of protection of the personal data we process. The data in the server log files is stored separately from all personal data provided by a person. The legal basis for data processing is Sec. 6 para. 1 lit. f GDPR. Our justified interest follows from the purposes listed above for data collection. The data will be deleted as soon as they are no longer necessary to achieve the purpose for which they were collected. This is the case after seven days at the latest. Further storage is possible. In this case, the IP addresses of the users are deleted or shortened, so that an assignment of the client is no longer possible.


1.2 Collection of personal data


It is, in principle, possible to visit our website without your personal data being processed if you have denied the use of cookies. You may not be able to use all of the functions on the website in this case. Please read our declaration for information about the use of cookies. We use the navigation information (data about your computer and visit to our website, in particular, your location, the browser you are using, referral source, length of your visit and the pages you opened) to improve your browser use and the services offered.


2. Contact options


If you use the contact form on our website or otherwise contact us electronically (for instance via email), we will save and process your personal data. You can use this channel to ask us questions about our solution and consulting offers, other questions about LD, ask for an individual offer or submit comments. Personal data you voluntarily provide us will be saved for processing purposes or so we can contact you as well as for possible follow-up questions. For this purpose, we process your following details: last name, first name, email address, telephone number and your message, which you provide us in accordance with your preferences as we can derive them from your query. This personal data will not be passed on to third parties.


The data specified and sent to us in the contact form and via email is processed based on Sec. 6 para. 1 lit. f GDPR. Our justified interest serves the purpose of processing your sent contact enquiry. If you contact us to request an offer or return an order, the data entered in the contact form will be processed to carry out pre-contractual or contractual measures based on Sec. 6 para. 1 lit. b GDPR.

The data you entered in the contact form will remain with us until you request they be deleted, revoke your consent to the data being stored or the reason for the data being stored no longer applies (e.g. after your request has been processed). Mandatory statutory provisions, in particular retention periods, remain unaffected.


3. Third-party websites


Our website contains links to external pages whose content is not located on our server. This is because we have a justified interest in enriching and relating our content to others. LD makes no guarantees with regard to such third-party websites and assumes no responsibility with respect to such third-party websites. You should be aware that the owners and operators of such third-party websites may possibly collect, use or disclose personal data in a manner other than that applied by LD. When accessing internet links to third-party websites, you should review the data privacy policies of these third-party websites. You should also be aware of the fact that third-party websites may use cookies. This data protection policy only applies to content stored on our servers.


Who receives or has access to your personal data?

1. Use of service providers


We utilise service providers who help us operate the website. For instance, we utilise hosting services and website analysing tools from our service providers and use IT support service providers. These service providers are contract processors in terms of data protection laws who only process the provided personal data on our behalf and in accordance with our instructions. We also contractually obligate our service providers to take sufficient technical and organisational measures to ensure the protection of your personal data. We regularly check to ensure that these measures are complied with. If our service providers are not located within the EU/the European Economic Area, we have established a reasonable level of data protection at our service providers (via EU - US Privacy Shield Frameworks certification or EU standard contract clauses).


What cookies do we use?

1. What are cookies?

We use so called cookies on our website. These are small text files that are downloaded and saved to the device you are using to surf on our website (e.g. a computer or smartphone, collectively referred to as “computer”) when you access a website. By using cookies, LD can provide the users of our website with user-friendly services that wouldn’t be possible without cookies in place, e.g. optimising information and services on our website for the user. That allows us to optimally design our website to meet your needs and improve your user experience even more.

Using cookies, you allow us to analyse the use of our website. When you visit our website for the first time, you will be informed that we use cookies on our website.


2. What kinds of cookies does LD use?


LD uses a variety of cookies on the website. These cookies are used for a variety of purposes. Depending on their purpose, cookies can be generally assigned to one of the following categories:


Required cookies:


These cookies are required to operate the website. They allow you to freely navigate through the site and use the functions you want to use on our website. If you do not permit the use of these cookies, your visit to the site may be limited and not all functions will be available.


Cookies required to execute the electronic communication process or provide specific functions you request will be saved in accordance with Sec. 6 para. 1 lit. f GDPR. The LD has a justified interest in saving cookies for the smooth and optimised technical provision of its services.


Analysis cookies


These cookies collect data about how the site is used, such as which subpages are visited most. These cookies provide LD analytical data about the performance of the site and insights into how LD can improve the site.


Google Analytics cookies are saved on the basis of Sec. 6 para. 1 lit. f GDPR. The LD has a justified interest in the analysis of the user behaviour to optimise both its online offer and its advertisements.


3. How can I allow, prohibit and manage cookies?


You can prevent the placement of cookies by our website at any time via the relevant settings in the browser and thus permanently prohibit their use. Already saved cookies can be deleted via your browser or other software programmes at any time. This is possible in all conventional Internet browsers. If you deactivate cookies in your Internet browser, not all of the functions of our website will be fully available to you.


You consent to the use of cookies if you continue surfing on the site after we have notified you of the use of cookies.

Please note that several functions or areas of the site will not be available if your browser does not allow cookies. You can find more information about how to change your browser settings at It is not possible to place an order with our online shop without the cookies we use. Instead, please call us by email or phone.

How long do we process your personal data?

We follow the principles of data avoidance and data minimisation. We therefore only save your personal data as long as it is required to achieve the objective specified here or as is required by the European bodies issuing guidelines and directives or another legislative body in laws or regulations to which LD is subject. Once the purpose no longer applies or these periods are over, the relevant data is routinely blocked or deleted in accordance with the relevant statutory regulations.
