3.1 General information about all Google services

The Google services listed here are provided by Google Ireland Limited (“Google”). You can make privacy settings for your Google account here: 

Google’s privacy policy can be found here: 

3.1.1 Google Analytics

We use Google Analytics, a web analytics service provided by Google, to analyze your use of the website. The information generated by the cookie about your visit to this website will be transmitted to and stored by Google on servers in the United States. Google uses this information to evaluate your use of the website, to compile reports on website activity for us and to provide us with other services related to website activity and internet usage. We are joint controllers with Google and have entered into a joint control agreement specified by Google through our account with Google. 

Summary of the Joint Control Agreement with Google: 

  • Each party is responsible for ensuring that a legal basis exists for the respective data processing.

  • Data subjects’ rights are implemented by Google, insofar as this does not involve exclusive data processing by us. However, to assert your data protection rights, you can contact us and/or Google.

  • The notification of data protection breaches in accordance with Art. 33 DS-GVO is handled by Google.  We are obligated to report immediately if we suspect a data protection breach. 

Google reserves the right to also process the data on servers in the USA and in this respect allows the EU standard contractual clauses and further protective measures to be applied, which are intended to guarantee an appropriate level of data protection (Art. 46 (2) c) DS-GVO).

To ensure anonymized collection of IP addresses, the source code of Google Analytics has been extended by the code “_anonymizeIp”, so that IP addresses are only processed in abbreviated form to exclude the possibility of personal references.

You can also prevent the storage of these cookies by setting your browser accordingly. You can also prevent the collection of data generated by the cookie and related to your use of our website (including your IP address) to Google and the processing of this data by Google by downloading and installing the browser plug-in available at the following link:  

You can alternatively prevent the collection and use of your data by Google by clicking on the following link:

Google Universal Analytics Opt Out.

Clicking this link will set an opt-out cookie that will prevent your data from being collected by Google.

Data by Google is collected in particular from users of a Gmail account, as Google is also the operator here. You can change your advertising settings for this at so that no more activities and information are collected for personalized advertising.

3.1.2 Google AdWords

This website also uses the online advertising program “Google AdWords” from Google, in particular conversion tracking. A conversion can be, for example, a registration, a page access or an inquiry. Google has developed a tool to measure these conversions and ultimately the effectiveness of AdWords ads. The conversion tracking cookie is set on your end device when you click on an ad placed by Google. These cookies expire after 30 days and are not used for personal identification. If you visit certain pages of this website and the cookie has not yet expired, we and Google can recognize that you clicked on the ad and were redirected to this page. Each Google AdWords customer receives a different cookie. Cookies can therefore not be tracked across AdWords customers’ websites. The information collected using the conversion cookie is used to create conversion statistics for AdWords customers who have opted in to conversion tracking. The customers, which include us, 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 any information that can be used to personally identify users. If you do not wish to participate in the tracking, you can easily deactivate the Google conversion tracking cookie via your internet browser under user settings. Furthermore, you can disable the use of these cookies in your advertising settings at Google.

3.1.3 Google Fonts

Mello also uses the “Google Fonts” tool for displaying the various fonts. This tool is also offered by Google. For this purpose, the IP address of the requesting end device is transmitted to the rights holder delivering the font. The processing is carried out in the legitimate interest of Mello to display the website content with the desired font (Art. 6 para 1 p. 1 f) DS-GVO). The IP address is deleted immediately after the font is retrieved. Here is more information about managing your own data in connection with Google products:

3.1.4 Google Tag Manager

The Google Tag Manager is a solution with which we can manage so-called website tags via an interface and thus integrate other services into our website. With the Tag Manager itself (which implements the tags), therefore, no profiles of users are created or cookies are stored yet, for example. Google only learns the IP address of the user, which is necessary to provide the service. 

3.1.5 Integrated YouTube videos

YouTube videos are embedded on our website. The provider of the corresponding plugins and the associated website at is Google. 

The videos are embedded via so-called inline frames (in short “iframes”) in extended data protection mode. An iframe is an element that is used to integrate content from other websites directly into our website via HTML. Information is only collected by Google when you consent and watch the video. After consenting, the cookies mentioned above are set. If you have already consented to play the video on another website, Google recognizes this by the cookie set. If you click on the video, Google receives the information from which website you call up the YouTube videos. If you are logged into your YouTube account, Google can assign your surfing behavior to you personally. You can prevent this by logging out of your YouTube account beforehand. For more information on data protection at “YouTube”, please refer to the privacy policy of this service, available at: Data collection is based on your consent (Art. 6 para. 1 p. 1 a) DS-GVO).

3.2 Facebook Analytics 

If you consent, Facebook may set the cookies described above to help us analyze the use of advertising content and display appropriate advertising. Facebook is operated by Facebook Ireland Ltd, 4 Grand Canal Square Grand Canal Harbour, Dublin 2 Ireland (“Facebook”). 

Facebook Analytics provides us with information on how users interact with our and our Facebook page. The information includes in particular: 

– Number of installs; 

– Number of posts and chats; 

– Number of active users; 

– Retention rate; and

– Number of app invitations. 

We are jointly responsible for data processing with Facebook. We have therefore entered into a Joint Control Agreement with Facebook as specified by Facebook. You can view that here.   

Summary of the Joint Control Agreement with Facebook:

  • Each party is responsible for ensuring that a legal basis exists for the respective data processing.

  • Data subject rights are implemented by Facebook, insofar as it is not an exclusive data processing by us. However, to assert your data subject rights, you can contact us and/or Facebook.

  • The notification of data protection breaches in accordance with Art. 33 DS-GVO is handled by Facebook.  We are obligated to report any suspected data breaches immediately.

On our website, we link to Facebook, LinkedIn and Instagram. If you click on the corresponding icon, you will be redirected to the website of the respective social media provider. In doing so, the provider receives the information from which website you are visiting its page. If you are logged into your Facebook, LinkedIn or Instagram account, the respective provider can assign your surfing behavior to you personally. You can prevent this by logging out of your respective account beforehand.

  1. Data transfers to third countries and third parties

We also process data in countries outside the European Economic Area (“EEA”). Within the scope of the services outlined in section 3, processing by third-party providers also takes place in the USA.

We will delete or anonymize your personal data as soon as it is no longer necessary for the purposes for which we collected or used it in accordance with the above paragraphs. If we are required by law to retain data, such periods are 6-10 years. Furthermore, data may be retained for a longer period as long as the data is related to litigation or criminal proceedings.
