Google Analytics IP Anonymisation

We implemented Google Analytics’ IP address anonymisation to this website. Google developed this function, so this website can comply with the applicable privacy laws and the local data protection authorities’ recommendations, should they prohibit the retention of any full IP addresses.
The anonymisation or masking of IP addresses takes place, as soon as they reach Google Analytics’ data collection network, but before the data would be saved or processed.

You can find more information on IP anonymisation at https://support.google.com/analytics/answer/2763052?hl=en.

​

Google Analytics Google Signals Privacy Policy

We have activated Google signals in Google Analytics. Through this, any existing Google Analytics functions (advertising reports, remarketing, cross-device reports and reports on interests and demographic characteristics) are updated, to result in the summary and anonymisation of your data, should you have permitted personalised ads in your Google Account.

The special aspect of this is that it involves cross-device tracking. That means your data can be analysed across multiple devices. Through the activation of Google signals, data is collected and linked to the Google account. For example, it enables Google to recognise when you look at a product on a smartphone and later buy the product on a laptop. Due to activating Google signals, we can start cross-device remarketing campaigns, which would otherwise not be possible to this extent. Remarketing means, that we can show you our products and services across other websites as well.

Moreover, further visitor data such as location, search history, YouTube history and data about your actions on our website are collected in Google Analytics. As a result, we receive improved advertising reports and more useful information on your interests and demographic characteristics. These include your age, the language you speak, where you live or what your gender is. Certain social criteria such as your job, your marital status or your income are also included. All these characteristics help Google Analytics to define groups of persons or target audiences.

Those reports also help us to better assess your behaviour, as well as your wishes and interests. As a result, we can optimise and customise our products and services for you. By default, this data expires after 26 months. Please consider, that this data is only collected if you have agreed to personalised advertisement in your Google Account. The retained information is always exclusively summarised and anonymous data, and never any data on individual persons. You can manage or delete this data in your Google Account.

​

Google Tag Manager Privacy Policy

We use Google Tag Manager by the company Google Inc. (1600 Amphitheatre Parkway Mountain View, CA 94043, USA) for our website.
This Tag Manager is one of Google’s many helpful marketing products. With it, we can centrally integrate and manage code sections of various tracking tools, that we use on our website.

In this privacy statement we will explain in more detail, what Google Tag Manager does, why we use it and to what extent your data is processed.

​

What is Google Tag Manager?

Google Tag Manager is an organising tool with which we can integrate and manage website tags centrally and via a user interface. Tags are little code sections which e.g. track your activities on our website. For this, segments of JavaScript code are integrated to our site’s source text. The tags often come from Google’s intern products, such as Google Ads or Google Analytics, but tags from other companies can also be integrated and managed via the manager. Since the tags have different tasks, they can collect browser data, feed marketing tools with data, embed buttons, set cookies and track users across several websites.

​

Why do we use Google Tag Manager for our website?

Everybody knows: Being organised is important! Of course, this also applies to maintenance of our website. In order to organise and design our website as well as possible for you and anyone who is interested in our products and services, we rely on various tracking tools, such as Google Analytics.
The collected data shows us what interests you most, which of our services we should improve, and which other persons we should also display our services to. Furthermore, for this tracking to work, we must implement relevant JavaScript Codes to our website. While we could theoretically integrate every code section of every tracking tool separately into our source text, this would take too much time and we would lose overview. This is the reason why we use Google Tag Manager. We can easily integrate the necessary scripts and manage them from one place. Additionally, Google Tag Manager’s user interface is easy to operate, and requires no programming skills. Therefore, we can easily keep order in our jungle of tags.

​

What data is saved by Google Tag Manager?

Tag Manager itself is a domain that neither uses cookies nor stores data. It merely functions as an “administrator“ of implemented tags. Data is collected by the individual tags of the different web analysis tools. Therefore, in Google Tag Manager the data is sent to the individual tracking tools and does not get saved.

However, with the integrated tags of different web analysis tools such as Google Analytics, this is quite different. Depending on the analysis tool used, various data on your internet behaviour is collected, stored and processed with the help of cookies. Please read our texts on data protection for more information on the articular analysis and tracking tools we use on our website.

We allowed Google via the account settings for the Tag Manager to receive anonymised data from us. However, this exclusively refers to the use of our Tag Manager and not to your data, which are saved via code sections. We allow Google and others, to receive selected data in anonymous form. Therefore, we agree to the anonymised transfer of our website data. However, even after extensive research we could not find out what summarised and anonymous data it is exactly that gets transmitted. What we do know is that Google deleted any info that could identify our website. Google combines the data with hundreds of other anonymous website data and creates user trends as part of benchmarking measures. Benchmarking is a process of comparing a company’s results with the ones of competitors. As a result, processes can be optimised based on the collected information.

​

How long and where is the data saved?

When Google stores data, this is done on Google’s own servers. These servers are located all over the world, with most of them being in America. At https://www.google.com/about/datacenters/inside/locations/?hl=en you can read in detail where Google’s servers are.

In our individual data protection texts on the different tools you can find out how long the respective tracking tools save your data.

​

How can I delete my data or prevent data retention?

Google Tag Manager itself does not set any cookies but manages different tracking websites’ tags. In our data protection texts on the different tracking tools you can find detailed information on how you can delete or manage your data.

Google actively participates in the EU-U.S. Privacy Shield Framework, which regulates safe transfer of personal data. You can find more information at https://www.privacyshield.gov/participant?id=a2zt000000001L5AAI&tid=111273745.

Google AdSense Privacy Policy

We use Google AdSense on this website. It is an advertising program of the company Google Inc. (1600 Amphitheatre Parkway Mountain View, CA 94043, USA). With Google AdSense we can show advertisements that fit our theme. Thus, we can offer you adverts that ideally give you added value. In this privacy statement on Google AdSense we will explain to you, why we use Google AdSense on our website and which of your data is processed and saved, as well as how you can prevent this data retention.

​

What is Google AdSense?

The advertising program Google AdSense has been around since 2003. As opposed to Google Ads (previously: Google AdWords) it is not possible to advertise on Google AdSense oneself. Google AdSense displays advertisements on websites, such as ours. The biggest advantage of this web service compared to some others, is that Google AdSense only shows ads to you which match our website’s contents. Google has its own algorithm which calculates what ads are shown to you. Of course, we only want to show you ads that interest you and provide you added value. Google checks which advertisements are suitable for our users, considering your interests, your user behaviour and our offer. At this point we want to mention that we are not responsible for the choice of the ads. We merely offer advertising space on our website, while Google selects the displayed ads. Moreover, since August 2013 the ads are customised to the respective user interface. This means, that no matter if you visit our website with your smartphone, your PC or your laptop, the ads adjust to your terminal device.

​

Why do we use Google AdSense on our website?

The operation of a high-quality website requires tremendous dedication and commitment. We are essentially never finished with working on our website. This is, because we continuously maintain and keep our website up to date. Of course, we want to achieve economic success with this work. Therefore, we decided for to use advertisements as a source of revenue. It is most important to us however, that we do not disrupt your visit to our website with these advertisements. Thence, with the aid of Google AdSense, only adverts that are tailored to you and our themes are shown.

Like with Google’s indexation for a website, a bot examines both, the matching content and the offers on our website. Then, the ads are adapted to and presented on the website. Alongside the contextual overlaps between the ads and website offer, AdSense also supports interest-based targeting. This means, that Google also uses your data to offer advertising that is tailored to you. That way you receive ads that ideally offer you added value, and it gives us a higher chance of earning a bit.

​

What data is stored by Google AdSense?

Google AdSense uses cookies to display ads that are customised to you. Cookies are little text files, that store certain information on your computer.

Cookies are supposed to enable improved advertisements in AdSense. They do not contain any personally identifiable data. However, it should be considered that Google does not view data such as “Pseudonymous Cookie-IDs” (name or other identification feature is replaced with a pseudonym) or IP addresses as personally identifiable information. Although, within the framework of the GDPR, this data can be classified as personal data. Following every impression (every time you see an ad), every click and any other activity that leads to a call on its servers, Google AdSense sends a cookie to the browser. The cookie is then saved in the browser, provided the browser accepts it.

Under certain circumstances, third parties can place cookies in your browser, and read them or use web beacons, to store data they receive through the display of ads on the website. Web beacons are little graphics that analyse and a record the log file. This analysis allows a statistical evaluation for the online marketing.

Through this cookie, Google can collect certain information on your user behaviour on our website. These include:

• Information on how you interact with an ad (clicks, impressions, mouse movements)

• Information if an ad has already been displayed in your browser. This data helps to prevent an ad from showing multiple times.

Thereby, Google evaluates and analyses data on the displayed advertising material along with your IP address. Primarily, Google uses the data to measure the effectiveness of an ad and improve the advertising offer. Moreover, the data does not get linked to your personal data which Google might have received via other Google services.

In the following we will introduce you to the cookies that Google AdSense uses for tracking purposes. Please note, that we will refer to a test website, which only has Google AdSense installed to it:

If you do not have a Google account or are not logged in, Google usually stores the collected data on your browser with a unique identification (ID). The IDs saved in cookies serve e.g. for providing personalised advertisements. If you are logged into a Google account, Google can gather personal information.

You can delete certain data that is saved by Google anytime (see next section). Much of the information saved in cookies get automatically deleted after a specific time. However, there are also data which are retained by Google for a longer period. This is the case, when Google must store certain data for an undefined, longer period due to economical or legal necessities.

​

How can I delete my data or prevent data retention?

You can always clear or deactivate cookies that are on your computer. How exactly this can be done depends on the browser.

Here you can find an instruction on how you can manage cookies in your browser:

Google Ads (Google AdWords) Conversion Tracking Privacy Policy

We use Google Ads (previously Google AdWords) as an online marketing measure, to advertise our products and services. Thus, we want to draw more people’s attention on the internet to the high quality of our offers. As part of our advertising measures with Google Ads, we use the conversion tracking of Google LLC., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA (“Google”) on our website. With the aid of this free tracking tool we can tailor our advertising offer better to your interests and needs. In the following article we will explain, why we use conversion tracking, what data gets saved and how you can prevent this data retention.

​

What is Google Ads conversion tracking?

Google Ads (previously Google AdWords) is the internal online advertising sxstem of the company Google LLC. We are convinced of our offer‘s quality and would like as many people as possible to discover our website. For this, Google Ads offers the best platform within the online environment. Of course, we also want to get an overview of the cost-benefit factor of our advertising campaigns. Thence, we use Google Ads’ conversion tracking tool.

But what is a conversion actually? A conversion occurs, when you turn from an interested visitor into an acting website visitor. This happens every time you click on our ad and then make another action, such as paying a visit to our website. With Google’s conversion tracking tool, we can understand what happens after a user clicks our Google ad. It shows us for instance if products get bought, services are used or whether users have subscribed to our newsletter.

​

Why do we use Google Ads conversion tracking on our website?

We use Google Ads to show our offer also across other websites. Our aim is for our advertising campaigns to reach only those people, who are interested in our offers. With the conversion tracking tool, we see what keywords, ads, ad groups and campaigns lead to the desired customer actions. We see how many customers interact with our ads on a device, to then convert. With this data we can calculate our cost-benefit-factor, measure the success of individual ad campaigns and therefore optimise our online marketing measures. With the help of the obtained data we can give our website a more interesting design and customise our advertising offer better to your needs.

​

What data is stored with Google Ads conversion tracking?

For a better analysis of certain user actions, we have integrated a conversion tracking tag, or code snippet to our website. Therefore, if you click one of our Google ads, a Google domain stores the cookie “conversion” on your computer (usually in the browser) or on your mobile device. Cookies are little text files that save information on your computer.

Here are data of the most significant cookies for Google’s conversion tracking:

Name: Conversion
Value: EhMI_aySuoyv4gIVled3Ch0llweVGAEgt-mr6aXd7dYlSAGQ111273745-3
Purpose: This cookie saves every conversion you make on our website after you came to us via a Google ad.
Expiry date: after 3 months

Name: _gac
Value: 1.1558695989.EAIaIQobChMIiOmEgYO04gIVj5AYCh2CBAPrEAAYASAAEgIYQfD_BwE
Purpose: This is a classic Google Analytics Cookie that records various actions on our website.
Expiry date: after 3 months

Note: The cookie _gac only appears in connection with Google Analytics. The above list does not claim to be exhaustive, as Google repeatedly change the cookies they use for analytical evaluation.

As soon as you complete an action on our website, Google identifies the cookie and saves your action as a so-called conversion. For as long as you surf our website, provided the cookie has not expired, both Google and us can determine that you found your way to us via a Google ad. Then, the cookie is read and sent back to Google Ads, together with the conversion data. Moreover, other cookies may also be used for measuring conversions. Google Ads‘ conversion tracking can be fine-tuned and improved with the aid of Google Analytics. Furthermore, ads which Google displays in various places across the web, might be placed under our domain with the name “__gads” or “_gac”.
Since September 2017, analytics.js retains various campaign information with the _gac cookie. This cookie stores data, as soon as you open one of our sites that has been set up for Google Ads’ auto-tagging. In contrast to cookies that are placed for Google domains, Google can only read these conversion cookies when you are on our website. We do neither collect nor receive any personal data. We do obtain a report with statistical evaluations by Google. With the help thereof, we can not only see the total number of users who clicked our ad, but also what advertising measures were well received.

​

How long and where is the data stored?

At this point we want to reiterate, that we have no influence on how Google use the collected data. According to Google, the data are encrypted and saved on a secure server. In most cases, conversion cookies expire after 30 days, and do not transmit any personalised data. The cookies named “conversion“ and “_gac“ (which is used with Google Analytics) have an expiry date of 3 months.

​

How can I delete my data or prevent data retention?

You have the possibility to opt out of Google Ads’ conversion tracking. The conversion tracking can be blocked by deactivating the conversion tracking cookie via your browser. If you do this, you will not be considered for the statistic of the tracking tool. You can change the cookie settings in your browser anytime. Doing so, works a little different in every browser. Hence, in the following you will find an instruction on how to manage cookies in your browser:

Chrome: Clear, enable and manage cookies in Chrome

Safari: Manage cookies and website data in Safari

Firefox: Clear cookies and site data in Firefox

Internet Explorer: Delete and manage cookies

Microsoft Edge: Delete cookies in Microsoft Edge

If you generally do not want to allow any cookies at all, you can set up your browser to notify you whenever a potential cookie is about to be set. This lets you decide upon permitting or denying the cookie’s placement. By downloading and installing the browser plugin at https://support.google.com/ads/answer/7395996 you can also deactivate all “advertising cookies”. Please consider that by deactivating these cookies, you cannot prevent all advertisements, only personalised ads.

Due to the certification for the American-European data protection convention “Privacy Shield”, the American corporation Google LLC must comply to the EU’s applicable data protection laws. If you want to find out more on data protection at Google, we recommend Google’s general Privacy Policy: https://policies.google.com/privacy?hl=en-GB.
