Privacy Policy

Data protection

Data protection is very important to us. This data protection declaration informs you about the type, scope and purpose of the collection and use of personal data via our website in accordance with the German Data Protection Ordinance (DSGVO).

Access data and log files

We store information into log files that your browser transmits to us. These are

  • browser type/version,
  • the operating system used,
  • referrer URL (the previously visited page),
  • the host name of the accessing computer (IP address),
  • the time of the server request,
  • the amount of data transmitted and
  • the message whether the retrieval was successful.

This data will not be passed on to third parties. The use of all offered services is permitted – if and so far technically possible and reasonable – without specification of any personal data or under specification of anonymized data or an alias. Since data transmission on the Internet (e.g. communication by e-mail) can be subject to security gaps, it is not possible to protect data completely from access by third parties.

Log files are automatically deleted after one month.

Dealing with personal data

Personal data is information that can be traced back to help to identy a person. This includes the name, e-mail address or telephone number. But also data about preferences, hobbies, memberships or which websites were viewed by someone count as personal data. We only collect, use and pass on personal data if this is permitted by law or if you as a user agree to the collection of data.

Getting in touch with us

When you contact us (e.g. via contact form or e-mail) your details will be stored for the purpose of processing the enquiry and in the event that follow-up questions arise.


We use cookies on our website. Cookies are small files that allow your access device (PC, smartphone or similar) to store specific information related to the device. They serve the user-friendliness of web pages and thus you (for example when saving login data or confirming the cookie banner).

In addition, statistical data can be collected from the use of the website, which can contribute to the improvement of the website. You yourself can influence the use of cookies. Most browsers have an option that restricts or completely prevents the storage of cookies. However, we would like to point out that the use and, in particular, the convenience of using cookies without cookies are restricted.

You can manage many online ad cookies from companies via the US website http://www.aboutads.info/choices/ or the EU website http://www.youronlinechoices.com/uk/your-ad-choices.

Comments and Contributions

If you leave comments or other posts on our website, your IP addresses will be stored for 7 days. This is done for our security if someone writes illegal content (insults, forbidden political propaganda, etc.) in comments and posts. In this case, we ourselves may be prosecuted for the comment or post and therefore we are interested in the identity of the author.

Integration of third-party services and content

We may include third-party content within our website, such as YouTube videos, Google Maps maps, RSS feeds, graphics from other websites or downloads. This always presupposes that the providers of this content (hereinafter referred to as “third-party providers”) determine your IP address. Without your IP address, the third party content providers will not be able to send the content to your browser. The IP address is therefore required for the presentation of this content. We make every effort to use only those contents whose respective providers only use the IP address to deliver the contents. However, we have no influence on whether the third party providers store the IP address for statistical purposes, for example. As far as this is known to us, we will inform you about it.

Google Analytics

We use Google Analytics, a web analysis service provided by Google Inc. (“Google”). Google Analytics uses “cookies”. The information generated by the cookie about your use of this website will generally be transmitted to and stored by Google on servers in the United States. Google processes website usage data on our behalf and is contractually committed to measures to ensure the security and confidentiality of the data processed.

We use Google Analytics only with IP anonymization enabled. This means that your IP address will be truncated by Google within member states of the European Union or other signatory states to the Agreement on the European Economic Area. Only in exceptional cases is the full IP address transmitted to a Google server in the USA and truncated there. On our behalf, Google will use this information to evaluate your use of the website, to compile reports on website activity and to provide other services to us relating to website activity and internet usage.

The IP address transmitted by your browser as part of Google Analytics will not be aggregated with other data held by Google. You can also prevent Google from collecting the data generated by the cookie and related to your use of the website (including your IP address) as well as Google from processing this data by downloading and installing the browser plug-in available under the following link  https://tools.google.com/dlpage/gaoptout?hl=de.

You can find out more about Google’s use of data, setting and objection options on Google’s websites:

Google Fonts

We use fonts from Google, LLC (https://www.google.com/fonts), which are integrated locally on our web server. There is no connection to Google servers or data transfer.


We use external code from the JavaScript framework “jQuery”, provided by the third party provider jQuery Foundation, https://jquery.org.

MailChimp (Newsletter-Service)

Our newsletter is sent using “MailChimp”, a newsletter sending platform of the US provider Rocket Science Group, LLC, 675 Ponce De Leon Ave NE #5000, Atlanta, GA 30308, USA.

To subscribe to our newsletter, it is sufficient for you to provide us with your email address and then confirm it separately. The request for first and last name is optional and only serves the purpose of personalising the newsletter. The email address and your name are stored on MailChimp’s servers in the USA. MailChimp uses this information to send and evaluate the newsletter on our behalf. In a separate “Data Processing Agreement” concluded with us, MailChimp undertakes to protect our users’ data and not to pass it on to third parties. We trust in the reliability and IT and data security of MailChimp. If you are interested, you can find more information at http://mailchimp.com/legal/privacy/.

Our newsletters contain a so-called “web beacon”, i.e. a pixel-sized file that is retrieved from the MailChimp server when the newsletter is opened. As part of this retrieval, technical information such as information about the browser, your system and your IP address is collected. The statistical surveys also include the determination of whether the newsletters are opened, when they are opened and which links are clicked. For technical reasons, this information can be assigned to individual newsletter recipients, but it is neither our intention nor that of MailChimp to observe individual users. The analyses are used to identify the reading habits of our users and to adapt our content to them or to send different content according to the interests of our users. MailChimp may use the analyses to optimise its own services, but will not use the data of our newsletter recipients to write to them itself or pass it on to third parties.

There are cases in which we direct newsletter recipients to MailChimp’s websites, e.g. to retrieve a newsletter online or to subsequently correct transmitted email addresses. Cookies are used on MailChimp’s websites and thus personal data is processed by MailChimp. We have no influence on this data collection.

You can revoke your consent to the storage of data, the e-mail address and its use for sending the newsletter at any time. The revocation can be made via a link in a newsletter itself or by notifying us. Insofar as you have not subscribed to any newsletter or e-mail services, no data will be transmitted either.


Within our online offering and in particular in the blog we use Gravatar, a service from Automattic, Inc. 132 Hawthorne Street San Francisco, CA 94107, USA.

Gravatar is a service where users can register and store profile pictures and their e-mail addresses. If users leave contributions or comments with the respective e-mail address on other online presences (especially in blogs), their profile pictures can be displayed next to the contributions or comments. For this purpose, the e-mail address provided by the users is encrypted and transmitted to Gravatar for the purpose of checking whether a profile is stored for it.

Gravatar is used on the basis of our legitimate interests within the meaning of Art. 6 Para. 1 lit. f) DSGVO, since with the help of Gravatar we offer authors of contributions and comments the opportunity to personalise their contributions with a profile picture. Automattic is certified under the Privacy Shield Agreement and thus offers a guarantee of compliance with European data protection law (https://www.privacyshield.gov/participant?id=a2zt0000000CbqcAAC&status=Active).

By displaying the images, Gravatar knows the IP address of the user, as this is necessary for communication between a browser and an online service. For more information on how Gravatar collects and uses this information, please refer to Automattic’s privacy policy:  https://automattic.com/privacy/.

If users do not want a user image linked to their e-mail address to appear in the comments at Gravatar, they should use an e-mail address which is not stored at Gravatar for commenting. We would also like to point out that it is also possible to use an anonymous e-mail address or no e-mail address at all if users do not wish their own e-mail address to be sent to Gravatar. Users can completely prevent the transmission of data by not using our comment system.

Social Networks

We use the social network LinkedIn to exchange information with customers and interested parties. When calling up corresponding networks and platforms, the terms and conditions and data processing guidelines of the respective operators apply.

Revocation, Amendments, Corrections and Updates

You have the right, upon request and free of charge, to obtain information about the personal data stored about you. In addition, you have the right to have incorrect data corrected, your personal data blocked or deleted, provided that this is not contrary to any legal obligation to retain such data. You also have the right to revoke your consent with effect for the future.

Right to Information

Your trust is important to us. Therefore we are happy to answer your questions regarding the processing of your personal data. If necessary, please write to datenschutz@t2informatik.de and receive information about your data stored by us.


Thank you for your trust.
