The protection of your personal data is an important matter for us. When operating our website and carrying out the LESER GmbH & Co.

We would like to provide you with more information on the collection, processing and usage of personal data at LESER GmbH & Co. KG in the following:

We collect personal data such as your company, surname, first name, address, telephone numbers and/or email address when carrying out online activities initiated by you (e.g. by using our contact form) (all of the above can also be summarised as "online offering"). Furthermore, we do not collect any personal data unless you voluntarily make this available to us, for example as part of a request or when contacting us through our contact form. The above types of personal data are saved by us. We collect and save such personal data only when and if the German Federal Data Protection Act (Bundesdatenschutzgesetz, BDSG) or other applicable legislation allows it or if you, as the concerned party, have given permission for it. If we provide our customers with the technical capacity to process data using our service or free-of-charge online offering, we are then the contracted data processor in the sense of § 11 BDSG – the responsible body in this case is then our customer/user.

Implementation of contracts and carrying out of free-of-charge offers: We utilise (i.e. process and use) the personal data that we collect primarily for establishing and executing contractual relationships as well as for carrying out activities initiated by you (e.g. free-of-charge website usage options), answering your requests or to grant you access to certain information or offers.

Marketing: We also use personal data to maintain existing customer relationships, e.g. for carrying out online surveys as well as sending marketing information. The latter can include information about offers from selected partner companies.

If consent is required by the applicable legislation to send marketing material or to carry out market research (together "advertising purposes"), such information is only sent if you have given your consent. As a general rule, consent is asked for and granted electronically. The consent declaration is then logged by us and afterwards you can access the content of this declaration at any time through our website. Additionally you can permanently withdraw your consent at any time. Even in instances where consent is not required for your data to be used for advertising purposes, you can object to its use in this way at any time by writing to We discontinue usage of the concerned data for advertising purposes upon receiving your objection or withdrawal of previously given consent.

We use the anonymised data that we receive from usage of our online services for creating analyses and evaluations that can be used for statistical or marketing purposes. These can include, for example, analyses of our online offering's utilisation intensity and the popularity of individual offers and functions. On top of that, we reserve the right to also use personal data for other purposes permitted by the applicable data protection provisions, particularly for maintaining data security and preventing or investigating disruptions to and failure of our online offering (e.g. through deliberate attacks on IT systems). Personal data can also especially be used to improve our offering or to subcontract third parties to carry out technical or administrative services. Finally, data usage can also be required due to legal obligations or official or judicial order, as well as for establishing or maintaining legal rights or to dismiss legal claims.

Personal data is transferred to IT service providers contracted by us, particularly data centre operators, who have access to personal data from our area of responsibility. In certain cases it can be required to pass on personal data to third parties not based in the EU or European Economic Area (EEA). We only pass on your data to third parties based outside of the EU/EEA when we can ensure that they guarantee a sufficient level of data protection or if you have given us express consent to transfer your data.

When accessing our website and the online offering provided by it, certain usage-related information is collected and subsequently used to enable our customers/users to make permanent use of our online offering. This includes properties for identifying users (e.g. IP address) and usage-related information (e.g. details on usage start/end and length as well as the online offers used by you). Identified or identifiable persons can be inferred through this information, which therefore is personal data. The collection and usage of your usage-related data similarly takes place while observing the applicable legislation on data protection. The IP address of each user is recorded and saved with every usage session in order to secure the service's availability as well as the data and information security of our own systems.

Occasionally information is automatically collected when accessing our website (i.e. not via registration) that cannot be traced back to an identified or identifiable individual (e.g. internet browser and operating system used, domain name of the website linking you to us, number of visits, average visit length, pages visited). We use this information to determine the attractiveness of our website and to improve its performance and content.

It may be the case that we save information in the form of a cookie (i.e. a small file) on your computer when you visit our website. Cookies enable us, for example, to customise a website to your interests. Some of the cookies used by us are deleted when the browser session ends, that is, after you close your browser. In contrast, other cookies remain on your device and enable us or also our partner companies to recognise your browser upon your next visit (persistent cookies). You can set your browser to inform you of the presence of cookies, allowing you to accept cookies individually or to reject them in certain cases or in general. If you would prefer that we do not recognise your computer upon your next visit, please set your browser to either delete cookies from your hard drive, block all cookies or warn you before saving cookies. The help function in most browsers explains how you can prevent your browser from accepting new cookies, to get it to notify you when you receive a new cookie or how you can turn off all cookies received.

LESER GmbH & Co. KG enforces technical and organisational measures that are required to protect your personal data against unlawful processing, unlawful or unintentional modification or deletion as well as against loss, unauthorised forwarding or unauthorised access. We have implemented security standards to protect the personal information that you have provided us using standards and technologies customary in the trade. We regularly assess our system for potential weakness and attacks, and use a data centre that is access-restricted at system level to protect the data saved by you on our servers. However, as the internet is not a 100% secure environment, we cannot assume any guarantee or liability for the security of the data that you convey to us over the internet. There is no guarantee that information will not be accessed or that information will not be disclosed, modified or destroyed if our physical, technical and organisational security precautions are breached.

It can be the case that third-party content (such as YouTube videos, Google Map material, RSS feeds or graphics from other websites) is integrated into our online offering. A requirement for this is that the provider of the content (hereinafter referred to as "third-party provider") be able to see the user's IP address. Without an IP address, they cannot send their content to the relevant user's browser. The IP address is therefore required to show this content. We endeavour to use only such content where the respective providers use IP addresses only to deliver their content. However we do not have any influence over third-party providers saving IP addresses for statistical purposes, for example. If this is known to us, we inform users of it.

The LESER GmbH & Co. KG website contains links to other websites. LESER GmbH & Co. KG is not responsible for the data protection policies and content of these other websites.

If you no longer agree to your personal data being saved or if it has become incorrect, we will delete it or make the necessary corrections upon receiving a corresponding instruction from you (insofar as this is possible under applicable legislation). Data kept for invoicing and bookkeeping purposes is however not affected by cancellation/withdrawal or deletion. Upon express request you can receive information on all the personal data we have saved about you, naturally free-of-charge.

Personal data that has been given to us over our website is only saved for as long as it is needed to meet the purpose for which it was entrusted to us. If legal, particularly commercial and tax-related, retention periods must be maintained, the storage period for certain data can be up to ten years. Otherwise data is automatically deleted from our server.
