Data processing in the context of the provision of services


When contacting us (e.g. by contact form, e-mail, telephone or via social media), the information of the inquiring person is processed to the extent necessary to respond to the contact requests and any requested actions (e.g. names, addresses, e-mail, telephone numbers, text entries).

The response to contact requests in the context of contractual or pre-contractual relationships is made to fulfill our contractual obligations or to respond to (pre)contractual inquiries (Art. 6 para. 1 p. 1 lit. b. DSGVO) and otherwise on the base of legitimate interests in responding to the inquiries (Art. 6 para. 1 p. 1 lit. f. DSGVO).

Service provision

We process data of our contractual and business partners, e.g. customers and interested parties (collectively referred to as "contractual partners") in the context of contractual and comparable legal relationships as well as related measures and in the context of communication with contractual partners (or pre-contractual), e.g. to answer inquiries. This includes inventory data (e.g. names, addresses), payment data (e.g. bank details, invoices, payment history), contact data (e.g. e-mail, telephone numbers), contractual data (e.g. subject matter of contract, term).

We process this data to fulfill our (pre-) contractual obligations (Art. 6 para. 1 p. 1 lit. b. DSGVO), to secure our rights and for the purposes of the administrative tasks associated with this information as well as the entrepreneurial organization (Art. 6 para. 1 p. 1 lit. c and f. DSGVO). We only disclose the data of the contractual partners to third parties within the scope of applicable law to the extent that this is necessary for the aforementioned purposes or for the fulfillment of legal obligations or with the consent of the contractual partners (e.g. to participating telecommunications, transport and other auxiliary services as well as subcontractors, banks, tax and legal advisors, payment service providers or tax authorities).

We delete the data after the expiry of legal warranty and comparable obligations, i.e., generally after 4 years, unless the data is stored in a customer account, e.g., if it must be retained for legal archiving reasons (e.g., for tax purposes generally 10 years).

As far as we use third party providers or platforms to provide our services, the terms and conditions and privacy notices of the respective third party providers or platforms apply in the relationship between the users and the providers.

Cloud services

We use software services accessible via the Internet and running on the servers of their providers (so-called "cloud services") for the following purposes: document storage and management, calendar management, e-mailing, spreadsheets and presentations, exchanging documents, content and information with specific recipients or publishing websites, forms or other content and information, as well as chatting and participating in audio and video conferences.

In this context, personal data may be processed and stored on the servers of the providers if they are part of communication processes with us or otherwise processed by us as set out in this privacy policy. This data may include, in particular, master data (e.g. name, address) and contact data of the users (e.g. e-mail, telephone numbers), data on procedures, contracts, other processes and their contents (e.g. text entries, photographs, videos). The providers of the cloud services also process usage data and metadata (e.g. device information, IP addresses), which are used by them for security purposes and for service optimization.

If we ask for consent to use the cloud services, the legal basis for processing is consent (Art. 6 para. 1 sentence 1 lit. a DSGVO). Furthermore, their use may be part of our (pre)contractual services (Art. 6 para. 1 sentence 1 lit. b. DSGVO), provided that the use of the cloud services has been agreed in this context. Otherwise, user data is processed on the basis of our legitimate interests (i.e., interest in efficient and secure administration and collaboration processes) (Art. 6 para. 1 sentence 1 lit. f. DSGVO).

We use the following service provider, which has integrated the EU standard contractual clauses into its terms of use:


Microsoft Office applications, teams and stream (audio and video meetings), cloud storage services

Data collection on our website

Server log files

Our website is operated by a hosting service provider. Depending on the use of our website, our hosting service provider (hereinafter "hosting company") automatically stores and collects information in so-called server log files, which your browser automatically transmits to us. These are:

  • Browser type and browser version
  • Operating system used
  • Referrer URL
  • Host name of the accessing computer
  • Time of the server request
  • IP address

This is due to our legitimate interest in an efficient and secure provision of our online offer in accordance with Art. 6 Para. 1 lit. f in conjunction with Art. 28 GDPR.

Our hosting service provider is Vercel Inc, 340 S Lemon Ave #4133, Walnut, CA 91789, USA. Vercel has committed under a DPA and under the SCCs, which you can view below: HTTPS://VERCEL.COM/LEGAL/DPA#SCHEDULE-3.

SSL or TLS encryption

We use SSL or TLS encryption on our website. You can recognize an encrypted connection by the fact that the address line of the browser changes from "http://" to "https://" and by the lock symbol in your browser line.


Our websites partly use so-called cookies. These serve to make our offer more user-friendly, effective and secure. Cookies are small text files that are stored on your computer and saved by your browser.

If the cookies are so-called "session cookies", they are automatically deleted at the end of your visit. Other cookies remain stored on your terminal device until you delete them. These cookies enable us to recognize your browser on your next visit.

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 closing the browser.

Detailed information about cookies on our website can be found in a separate section: TO COOKIE STATEMENT.

Contact form

If you contact us via the contact form, your data from the contact form will be stored by us for the purpose of processing the request and in case of follow-up questions.

The processing of the data entered in the contact form is based on Art. 6 para. 1 lit. b DSGVO or on your consent pursuant to Art. 6 para. 1 lit. a DSGVO. You can object to this processing or revoke a declared consent at any time. For this purpose, an informal communication by e-mail to us is sufficient. The lawfulness of the data processing operations carried out until the objection or revocation remains unaffected.

The data you entered in the contact form will remain with us until you request us to delete it or the purpose for storing the data no longer applies. Mandatory legal provisions - in particular retention periods - remain unaffected.

Salesforce Sales Cloud

For communication via the contact form, we use the Service Sales Cloud, of the provider Germany GmbH, Erika-Mann-Str. 31, 80636 Munich. The data provided via the contact form is stored within the Salesforce Sales Cloud.

To manage the user accounts, we use the Salesforce Sales Cloud as a CRM system to be able to process user inquiries more quickly and efficiently. The use of the Salesforce Sales Cloud is thus made pursuant to Art. 6 (1) p. 1 lit. f DSGVO based on our legitimate economic interest to optimize our sales activities and to manage user accounts. These interests are considered legitimate within the meaning of the provision.

Salesforce assures that it processes data in compliance with the GDPR and ensures the protection of data subjects' rights. For this, Salesforce relies on binding corporate rules for compliance with the GDPR and the EU standard contractual clauses, both of which are included in Salesforce's Data Processing Addendum. HTTPS://WWW.SALESFORCE.COM/CONTENT/DAM/WEB/EN_US/WWW/DOCUMENTS/LEGAL/AGREEMENTS/EU-DATA-TRANSFER-MECHANISMS-FAQ.PDF

Salesforce uses the user's data only for the technical processing of the requests and does not pass them on to third parties. To use Salesforce, at least the provision of a correct e-mail address is necessary. Use under pseudonyms is possible. In the course of processing service requests, it may be necessary to collect further data (name, address).

If you do not agree to data collection via and data storage in Salesforce's external system, we offer you alternative contact options for submitting service requests by e-mail, telephone, fax or mail.

Web analytics and advertising

Google Conversion-Tracking

Our website uses the conversion tracking function as part of Google Ads from Google.

When you click on an ad placed by Google, a cookie is set for conversion tracking. This cookie loses its validity after 30 days and does not serve to identify you personally. If you visit certain pages of our website and the cookie has not yet expired, Google and we can recognize that you have clicked on the ad and were redirected to this page.

Each Google Ads customer receives a different cookie. The cookies cannot be tracked through Ads customers' websites. The information obtained using the conversion cookie is used to create conversion statistics for Ads customers who have opted in to conversion tracking. The customers learn the total number of users who clicked on their ad and were redirected to a page tagged with a conversion tracking tag. However, they do not receive information that personally identifies users. If you do not wish to participate in the tracking, you can object to this use by deactivating the Google conversion tracking cookie via your internet browser under user settings. You will then not be included in the conversion tracking statistics.
