We would like to point out that data transmission over the Internet (e.g. when communicating by e-mail) can have security gaps. A complete protection of the data against access by third parties is not possible.
Revocation of your consent to data processing
Many data processing operations are only possible with your express consent. You can revoke your consent at any time. An informal e-mail to us is sufficient. The legality of the data processing carried out before the revocation remains unaffected by the revocation.
Right of appeal to the competent supervisory authority
In the event of violations of data protection law, the person concerned has the right to lodge a complaint with the competent supervisory authority. The competent supervisory authority for data protection issues is the state data protection officer of the federal state in which our company is based.

Right to data portability
You have the right to have data that we process automatically on the basis of your consent or in fulfillment of a contract handed over to you or to a third party in a common, machine-readable format. If you request the direct transfer of the data to another person responsible, this will only be done if it is technically feasible.
SSL or TLS encryption
For security reasons and to protect the transmission of confidential content, such as orders or inquiries that you send to us as the website operator, this site uses an SSL or. TLS encryption.

6. Analysis tools and advertising
Google Analytics
This website uses functions of the web analysis service Google Analytics. The provider is Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, USA. Google Analytics uses so-called "cookies". These are text files that are saved on your computer and that enable your use of the website to be analyzed. The information generated by the cookie about your use of this website is usually transferred to a Google server in the USA and stored there.
The storage of Google Analytics cookies is based on Art. 6 Para. 1 lit.f GDPR. The website operator has a legitimate interest in analyzing user behavior in order to optimize both its website and its advertising.
IP anonymization
We have activated the IP anonymization function on this website. As a result, your IP address will be shortened by Google within member states of the European Union or in other contracting states of the Agreement on the European Economic Area before it is transmitted to the USA. The full IP address will only be transmitted to a Google server in the USA and shortened there in exceptional cases. On behalf of the operator of this website, Google will use this information to evaluate your use of the website, to compile reports on website activity and to provide the website operator with other services relating to website activity and internet usage. The IP address transmitted by your browser as part of Google Analytics will not be merged with other Google data.
Browser plugin
You can prevent the storage of cookies by setting your browser software accordingly; we would like to point out, however, that in this case you may not be able to use all functions of this website to their full extent. You can also prevent Google from collecting the data generated by the cookie and relating to your use of the website (including your IP address) and from processing this data by downloading the browser plug-in available under the following link and install: https://tools.google.com/dlpage/gaoptout?hl=de .
Objection against data collection

You can find more information on how Google Analytics handles user data in Google's privacy policy: https://support.google.com/analytics/answer/6004245?hl=de .
Order data processing
We have concluded a contract data processing agreement with Google and fully implement the strict requirements of the German data protection authorities when using Google Analytics.
Demographic characteristics in Google Analytics
This website uses the “demographic characteristics” function of Google Analytics. This allows reports to be created that contain information on the age, gender and interests of the site visitors. This data comes from interest-based advertising from Google as well as from visitor data from third-party providers. These data cannot be assigned to a specific person. You can deactivate this function at any time via the ad settings in your Google account or generally prohibit the collection of your data by Google Analytics as described in the section “Objection to data collection”.
Google Analytics remarketing
Our websites use the functions of Google Analytics Remarketing in conjunction with the cross-device functions of Google AdWords and Google DoubleClick. The provider is Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, USA.
This function enables the advertising target groups created with Google Analytics Remarketing to be linked with the cross-device functions of Google AdWords and Google DoubleClick. In this way, interest-related, personalized advertising messages that have been adapted to you depending on your previous usage and surfing behavior on one device (e.g. mobile phone) can also be displayed on another of your devices (e.g. tablet or PC).
If you have given your consent, Google will link your web and app browser history to your Google account for this purpose. In this way, the same personalized advertising messages can be displayed on every device on which you log in with your Google account.
To support this function, Google Analytics collects Google-authenticated user IDs, which are temporarily linked to our Google Analytics data in order to define and create target groups for cross-device advertising.
You can permanently object to cross-device remarketing / targeting by deactivating personalized advertising in your Google account; follow this link: https://www.google.com/settings/ads/onweb/.
The collected data is summarized in your Google account exclusively on the basis of your consent, which you can give to Google or revoke (Art. 6 Para. 1 lit. a GDPR). In the case of data collection processes that are not merged in your Google account (e.g. because you do not have a Google account or have objected to the merging), the collection of data is based on Article 6 (1) (f) GDPR. The legitimate interest arises from the fact that the website operator has an interest in the anonymized analysis of the website visitors for advertising purposes.
Further information and the data protection provisions can be found in Google's data protection declaration at: https://www.google.com/policies/technologies/ads/.
Google AdWords and Google Conversion Tracking
This website uses Google AdWords. AdWords is an online advertising program from Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, United States (“Google”).
We use so-called conversion tracking as part of Google AdWords. If you click on an ad placed by Google, a conversion tracking cookie is set. Cookies are small text files that the Internet browser stores on the user's computer. These cookies lose their validity after 30 days and are not used to personally identify users. If the user visits certain pages on this website and the cookie has not yet expired, we and Google can see that the user clicked on the ad and was redirected to this page.
Every Google AdWords customer receives a different cookie. The cookies cannot be tracked via the websites of AdWords customers. The information obtained using the conversion cookie is used to generate conversion statistics for AdWords customers who have opted for conversion tracking. The customers find out the total number of users who clicked on their ad and were redirected to a page with a conversion tracking tag. However, they do not receive any information with which users can be personally identified. If you do not want to participate in tracking, you can object to this use by easily deactivating the Google conversion tracking cookie in your internet browser under user settings. You will then not be included in the conversion tracking statistics.
The storage of “conversion cookies” takes place on the basis of Art. 6 Para. 1 lit. f GDPR. The website operator has a legitimate interest in analyzing user behavior in order to optimize both its website and its advertising.
You can find more information about Google AdWords and Google Conversion Tracking in Google's privacy policy: https://www.google.de/policies/privacy/.
You can set your browser so that you are informed about the setting of cookies and only allow cookies in individual cases, exclude the acceptance of cookies for certain cases or in general, and activate the automatic deletion of cookies when you close the browser. If cookies are deactivated, the functionality of this website may be restricted.
Google reCAPTCHA
We use “Google reCAPTCHA” (hereinafter “reCAPTCHA”) on our websites. The provider is Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, USA (“Google”).
The purpose of reCAPTCHA is to check whether data is entered on our website (e.g. in a contact form) by a person or by an automated program. To do this, reCAPTCHA analyzes the behavior of the website visitor based on various characteristics. This analysis begins automatically as soon as the website visitor enters the website. For the analysis, reCAPTCHA evaluates various information (e.g. IP address, length of stay of the website visitor on the website or mouse movements made by the user). The data collected during the analysis are forwarded to Google.
The reCAPTCHA analyzes run completely in the background. Website visitors are not informed that an analysis is taking place.

Facebook pixel
Our website uses the visitor action pixel from Facebook, Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA (“Facebook”) to measure conversion.
In this way, the behavior of the page visitors can be tracked after they have been redirected to the provider's website by clicking on a Facebook ad. This enables the effectiveness of the Facebook advertisements to be evaluated for statistical and market research purposes and future advertising measures to be optimized.
The data collected is anonymous for us as the operator of this website; we cannot draw any conclusions about the identity of the user. However, the data is stored and processed by Facebook so that a connection to the respective user profile is possible and Facebook can use the data for its own advertising purposes in accordance with the Facebook data usage guidelines. This enables Facebook to place advertisements on Facebook pages as well as outside of Facebook. As the website operator, we cannot influence this use of the data.
You will find further information on protecting your privacy in Facebook's data protection information: https://www.facebook.com/about/privacy/.
You can also use the remarketing function “Custom Audiences” in the advertising settings area under https://www.facebook.com/ads/preferences/?entry_product=ad_settings_screen deactivate. To do this, you have to be logged in to Facebook.
