Unfortunately, these subjects sound rather technical due to their nature, but we have put much effort into describing the most important things as simply and clearly as possible.
Automatic Data Retention
Every time you visit a website nowadays, certain information is automatically created and saved, just as it happens on this website.
Whenever you visit our website such as you are doing right now, our webserver (computer on which this website is saved/stored) automatically saves data such as
- the address (URL) of the accessed website
- browser and browser version
- the used operating system
- the address (URL) of the previously visited site (referrer URL)
- the host name and the IP-address of the device the website is accessed from
- date and time
in files (webserver-logfiles).
Generally, webserver-logfiles stay saved for two weeks and then get deleted automatically. We do not pass this information to others, but we cannot exclude the possibility that this data will be looked at in case of illegal conduct.
Our website uses HTTP-cookies to store user-specific data.
What exactly are cookies?
Every time you surf the internet, you use a browser. Common browsers are for example Chrome, Safari, Firefox, Internet Explorer and Microsoft Edge. Most websites store small text-files in your browser. These files are called cookies.
Cookies save certain parts of your user data, such as e.g. language or personal page settings. When you re-open our website, your browser submits these “user specific” information back to our site. Thanks to cookies, our website knows who you are and offers you the settings you are familiar to. In some browsers every cookie has its own file, in others such as Firefox, all cookies are stored in one single file.
There are both first-party cookies and third-party coookies. First-party cookies are created directly by our site, while third-party cookies are created by partner-websites (e.g. Google Analytics). Every cookie is individual, since every cookie stores different data. The expiration time of a cookie also varies – it can be a few minutes, or up to a few years. Cookies are no software-programs and contain no computer viruses, trojans or any other malware. Cookies also cannot access your PC’s information.
This is an example of how cookie-files can look:
purpose: differentiation between website visitors
expiration date: after 2 years
A browser should support these minimum sizes:
- at least 4096 bytes per cookie
- at least 50 cookies per domain
- at least 3000 cookies in total
Which types of cookies are there?
There are 4 different types of cookies:
These cookies are necessary to ensure the basic function of a website. They are needed when a user for example puts a product into their shopping cart, then continues surfing on different websites and comes back later in order to proceed to the checkout. Even when the user closed their window priorly, these cookies ensure that the shopping cart does not get deleted.
These cookies collect info about the user behaviour and record if the user potentially receives any error messages. Furthermore, these cookies record the website’s loading time as well as its behaviour within different browsers.
These cookies care for an improved user-friendliness. Thus, information such as previously entered locations, fonts or data in forms stay saved.
These cookies are also known as targeting-Cookies. They serve the purpose of delivering individually adapted advertisements to the user. This can be very practical, but also rather annoying.
Upon your first visit to a website you are usually asked which of these cookie-types you want to accept. Furthermore, this decision will of course also be saved in a cookie.
How can I delete cookies?
If you want change or delete cookie-settings and would like to determine which cookies have been saved to your browser, you can find this info in your browser-settings:
If you generally do not want to allow any cookies at all, you can set up your browser in a way, to notify you whenever a potential cookie is about to be set. This gives you the opportunity to manually decide to either permit or deny the placement of every single cookie. The settings for this differ from browser to browser. Therefore, it might be best for you to search for the instructions in Google. If you are using Chrome, you could for example put the search phrase “delete cookies Chrome” or “deactivate cookies Chrome” into Google.
How is my data protected?
If you want to learn more about cookies and do not mind technical documentation, we recommend https://tools.ietf.org/html/rfc6265, the Request for Comments of the Internet Engineering Task Force (IETF) called “HTTP State Management Mechanism”.
Storage of Personal Data
Any personal data you electronically submit to us on this website, such as your name, email address, home address or other personal information you provide via the transmission of a form or via any comments to the blog, are solely used for the specified purpose and get stored securely along with the respective submission times and IP-address. These data do not get passed on to third parties.
Therefore, we use personal data for the communication with only those users, who have explicitly requested being contacted, as well as for the execution of the services and products offered on this website. We do not pass your personal data to others without your approval, but we cannot exclude the possibility this data will be looked at in case of illegal conduct.
If you send us personal data via email – and thus not via this website – we cannot guarantee any safe transmission or protection of your data. We recommend you, to never send confidential data via email.
Rights in accordance with the General Data Protection Regulation
- right to rectification (article 16 GDPR)
- right to erasure (“right to be forgotten“) (article 17 GDPR)
- right to restrict processing (article 18 GDPR)
- righ to notification – notification obligation regarding rectification or erasure of personal data or restriction of processing (article 19 GDPR)
- right to data portability (article 20 GDPR)
- Right to object (article 21 GDPR)
- right not to be subject to a decision based solely on automated processing – including profiling – (article 22 GDPR)
If you think that the processing of your data violates the data protection law, or that your data protection rights have been infringed in any other way, you can lodge a complaint with your respective regulatory authority. For Austria this is the data protection authority, whose website you can access at https://www.data-protection-authority.gv.at/.
TLS encryption with https
We use https to transfer information on the internet in a tap-proof manner (data protection through technology design Article 25 Section 1 GDPR). With the use of TLS (Transport Layer Security), which is an encryption protocol for safe data transfer on the internet, we can ensure the protection of confidential information. You can recognise the use of this safeguarding tool by the little lock-symbol, which is situated in your browser’s top left corner, as well as by the use of the letters https (instead of http) as a part of our web address.
On our website we use Google Maps of the company Google Inc. (1600 Amphitheatre Parkway Mountain View, CA 94043, USA). With the use of Google Maps, we can show you locations in a better way and can therefore adjust our service to your needs. Due to the utilisation of Google Maps, data gets transferred to Google and is saved on Google’s servers. In the following, we want to explain in detail what Google Maps is, why we use this Google service, what data is stored and how you can prevent this.
What is Google Maps?
Google Maps is an internet maps service of the company Google Inc. With Google Maps you can search for exact locations of cities, sights, accommodations or businesses online via a PC, a tablet or an app. If businesses are represented on Google My Business, the respective location as well as other information about the company are shown there. In order to show route directions, a location’s map sections can be integrated in a website through a HTML-code. Google Maps depicts the earth’s surface as either a road map or as air and satellite images. Due to the street view and high-quality satellite images, it is possible for exact representations to be made.
Why do we use Google Maps on our website?
The efforts we make on this page have the goal of giving you a useful and meaningful experience on our website. Through the integration of Google Maps, we can offer you essential information on various locations. Therefore, you can spot our office address with one glance. Furthermore, the route directions always show you the best and fastest way to us. You can retrieve the route directions for traveling either by car, by public transport, on foot or by bike. The integration of Google Maps is a part of our customer service.
What data is stored by Google Maps?
For Google Maps to offer its full services, the company must collect and store your data. This includes your entered search terms, your IP-address as well as your longitude and latitude coordinates. When you use the route-planner function, the entered start address is stored also. However, this data retention happens on Google Maps‘ websites. We can only inform you about it but cannot influence it in any way. Since we have included Google Maps on our website, Google will set at least one cookie (Name: NID) into your browser. This cookie saves data on your user behaviour. Google primarily uses this data to optimise ist own services and to provide you with individual, personalised advertisements.
The following cookies are set in your browser due to the integration of Google Maps:
Purpose: Google uses NID in order to adjust advertisments to your Google searches. With the cookie’s help Google “remembers“ your most frequently entered search queries or your previous interaction with ads. That way you always receive customised adertisments. The cookie contains a unique ID, wich Google uses to collect your personal settings for advertising porposes.
Expiration date: after 6 months
How long and where is the data saved?
There are Google servers in data centres across the entire planet. However, most servers are in America. For this reason, your data is widely stored in the USA. Here you can read in detail about where the Google servers are located: https://www.google.com/about/datacenters/inside/locations/?hl=en
Google distributes data to various data carriers. This makes it possible to retrieve the data faster and to better protect it from possible attempted manipulations. Every server has emergency programs. Thus, should for example a problem with Google’s hardware occur or should a natural disaster impact the servers, any data will quite certainly stay protected.
Moreover, Google saves some data for a specified period. With some other data on the other hand, Google only offers the opportunity for deleting it manually. Furthermore, the company anonymises information (e.g. advertising data) in server logs, by deleting a part of the IP-address and cookie information after 9 to 18 months.
How can I delete my data, or prevent data retention?
Due to the automatic delete function for location and activity data, which was introduced in 2019, information that is used for determining your location and web or app activity is saved for either 3 or 18 months, depending on your preferred decision, and is deleted thereafter.
Furthermore, it is possible to delete this data manually from your browser history via your Google account anytime. If you want to prevent the determination of your location altogether, you must pause the category “Web and app activity” in your Google account. Click on “Data and personalisation” and then choose the option “Activity controls”. Here you can switch the activities on or off.
Moreover, in your browser you can deactivate, delete or manage individual cookies. This function can differ a little, depending on what browser you are using. The following instructions will show you how to manage cookies in your browser:
If you generally do not want to permit any cookies, you can set up your browser in a way that ensures you get informed whenever a cookie is about to be placed. That way you can decide to either permit or refuse every single cookie.
Google is an active participant of the EU-U.S. Privacy Shield Framework, which regulates the correct and safe transfer of personal data. You can find more information on this on https://www.privacyshield.gov/participant?id=a2zt000000001L5AAI.
If you want to find out more about Google’s data processing, we recommend the company’s internal privacy statement on https://policies.google.com/privacy?hl=en-GB.
We use the tracking and analysis tool Google Analytics (GA) of the US-American company Google LLC (1600 Amphitheatre Parkway Mountain View, CA 94043, USA). Google Analytics collects data on your actions on our website. Whenever you click a link for example, this action is saved in a cookie and transferred to Google Analytics. With the help of reports which we receive from Google Analytics, we can adapt our website and our services better to your wishes. In the following, we will explain the tracking tool in more detail, and most of all, we will inform you what data is saved and how you can prevent this.
What is Google Analytics?
Google Analytics is a tracking tool with the purpose of conducting data traffic analysis of our website. For Google Analytics to work, there is a tracking code integrated to our website. Upon your visit to our website, this code records various actions you perform on your website. As soon as you leave our website, this data is sent to the Google Analytics server, where it is stored.
Google processes this data and we then receive reports on your user behaviour. These reports can be one of the following:
- Target audience reports: With the help of target audience reports we can get to know our users better and can therefore better understand who is interested in our service.
- Advertising reports: Through advertising reports we can analyse our online advertising better and hence improve it.
- Acquisition reports: Acquisition reports provide us helpful information on how we can get more people enthusiastic about our service.
- Behaviour reports: With these reports, we can find out how you interact with our website. By the means of behaviour reports, we can understand what path you go on our website and what links you click.
- Conversion reports: A conversion is the process of leading you to carry out a desired action due to a marketing message. An example of this would be transforming you from a mere website visitor into a buyer or a newsletter subscriber. Hence, with the help of these reports we can see in more detail, if our marketing measures are successful with you. Our aim is to increase our conversion rate.
- Real time reports: With the help of these reports we can see in real time, what happens on our website. It makes us for example see, we can see how many users are reading this text right now.
Why do we use Google Analytics on our website?
The objective of our website is clear: We want to offer you the best possible service. Google Analytics’ statistics and data help us with reaching this goal.
Statistically evaluated data give us a clear picture of the strengths and weaknesses of our website. On the one hand, we can optimise our page in a way, that makes it easier to be found by interested people on Google. On the other hand, the data helps us to get a better understanding of you as our visitor. Therefore, we can very accurately find out what we must improve on our website, in order to offer you the best possible service. The analysis of that data also enables us to carry out our advertising and marketing measures in a more individual and more cost-effective way. After all, it only makes sense to show our products and services exclusively to people who are interested in them.
What data gets stored by Google Analytics?
With the aid of a tracking code, Google Analytics creates a random, unique ID which is connected to your browser cookie. That way, Google Analytics recognises you as a new user. The next time you visit our site, you will be recognised as a “recurring” user. All data that is collected gets saved together with this very user ID. Only this is how it is made possible for us to evaluate and analyse pseudonymous user profiles.
Your interactions on our website are measures by tags such as cookies and app instance IDs. Interactions are all kinds of actions that you perform on our website. If you are also using other Google systems (such as a Google Account), data generated by Google Analytics can be linked with third-party cookies. Google does not pass on any Google Analytics data, unless we as the website owners authorise it. In case it is required by law, exceptions can occur.
The following cookies are used by Google Analytics:
Purpose: By deafault, analytics.js uses the cookie _ga, to save the user ID. It generally serves the purpose of differenciating between website visitors.
Expiration date: After 2 years
Purpose: This cookie also serves the purpose of differentiating between website users
Expiration date: After 24 hours
Verwendungszweck: It is used for decreasing the demand rate. If Google Analytics is provided via Google Tag Manager, this cookie gets the name _dc_gtm_ .
Expiration date: After 1 minute
Value: No information
Purpose: This cookie has a token which is used to retrieve the user ID by the AMP Client ID Service. Other possible values suggest a logoff, a request or an error.
Expiration date: After 30 seconds up to one year
Purpose: With this cookie your behaviour on the website can be tracked and the site performance can be measured. The cookie is updated every time the information is sent to Google Analytics.
Expiration date: After 2 years
Purpose: Just like _gat_gtag_UA_ this cookie is used for keeping the requirement rate in check.
Expiration date: Afer 10 minutes
Purpose: This cookie is used to determine new sessions. It is updated every time new data or information gets sent to Google Analytics.
Expiration date: After 30 minutes
Purpose: This cookie is used to determine new sessions for recurring visitors. It is therefore a session cookie, and only stays saved until you close the browser again.
Expiration date: After closing the browser
Purpose: This cookie is used to identify the source of our website’s visitor number. This means, that the cookie saves information on where you came to our website from. This could be another site or an advertisement.
Expiration date: After 6 months
Value: No information
Purpose: The cookie is used to store custom user data. It gets updated whenever information is sent to Google Analytics.
Expiration date: After 2 years
Note: This list is by no means exhaustive, since Google are repeatedly changing the use of their cookies.
Below we will give you an overview of the most important data that can be evaluated by Google Analytics:
Heatmaps: Google creates so-called Heatmaps an. These Heatmaps make it possible to see the exact areas you click on, so we can get information on what routes you make on our website.
Session duration: Google calls the time you spend on our website without leaving it session duration. Whenever you are inactive for 20 minutes, the session ends automatically.
Bounce rate If you only look at one page of our website and then leave our website again, it is called a bounce.
Account creation: If you create an account or make an order on our website, Google Analytics collects this data.
IP-Address: The IP address is only shown in a shortened form, to make it impossible to clearly allocate it.
Location: Your approximate location and the country you are in can be defined by the IP address. This process is called IP location determination.
Technical information: Information about your browser type, your internet provider and your screen resolution are called technical information.
Source: Both, Google Analytics as well as ourselves, are interested what website or what advertisement led you to our site.
Further possibly stored data includes contact data, potential reviews, playing media (e.g. when you play a video on our site), sharing of contents via social media or adding our site to your favourites. This list is not exhaustive and only serves as general guidance on Google Analytics’ data retention.
How long and where is the data saved?
Google has servers across the globe. Most of them are in America and therefore your data is mainly saved on American servers. Here you can read detailed information on where Google’s data centres are located: https://www.google.com/about/datacenters/inside/locations/?hl=en
Your data is allocated to various physical data mediums. This has the advantage of allowing to retrieve the data faster, and of protecting it better from manipulation. Every Google data centre has respective emergency programs for your data. Hence, in case of a hardware failure at Google or a server error due to natural disasters, the risk for a service interruption stays relatively low.
Google Analytics has a 26 months standardised period of retaining your user data. After this time, your user data is deleted. However, we have the possibility to choose the retention period of user data ourselves. There are the following five options:
- Deletion after 14 months
- Deletion after 26 months
- Deletion after 38 months
- Deletion after 50 months
- No automatical deletion
As soon as the chosen period is expired, the data is deleted once a month. This retention period applies to any of your data which is linked to cookies, user identification and advertisement IDs (e.g. cookies of the DoubleClick domain). Any report results are based on aggregated information and are stored independently of any user data. Aggregated information is a merge of individual data into a single and bigger unit.
How can I delete my data or prevent data retention?
Should you generally want to deactivate, delete or manage all cookies (independently of Google Analytics), you can use one of the guides that are available for any browser:
Google Analytics is an active participant of the EU-U.S. Privacy Shield Framework, which regulates correct and save transfer of personal data.
You can find more information on this at https://www.privacyshield.gov/participant?id=a2zt000000001L5AAI&tid=111388005. We hope we were able to make you more familiar with the most important information on Google Analytics’ data processing. If you want to learn more about the tracking service, we recommend both of the following links: https://marketingplatform.google.com/about/analytics/terms/gb/ and https://support.google.com/analytics/answer/6004245?hl=en.
When you subscribe to our Newsletter you submit your personal data and give us the right to contact you via email. We use the data that is stored for the registration for the Newsletter exclusively for our Newsletter and do not pass them on.
If you unsubscribe from the newsletter – for which you can find a link in the bottom of every newsletter – we will delete all data that was saved when you registered for the newsletter.
Like many other websites, we use the services of the newsletter company MailChimp on our website. The operator of MailChimp is the company The Rocket Science Group, LLC, 675 Ponce de Leon Ave NE, Suite 5000, Atlanta, GA 30308 USA. With the aid of MailChimp we can easily send you interesting news via newsletter. For the use of the service we do not have to install anything but can still access a pool of very efficient features. In the following we will give more details on this email marketing service and will inform you about the most important data protection aspects.
What is MailChimp?
MailChimp is a cloud-based newsletter management service. “Cloud-based“ means that we do not need to install MailChimp on our own computer or server. Instead, we use the service on an external server, or more specifically via an IT infrastructure, which is available via the internet. Using a software this way is also called SaaS (software as a service).
MailChimp allows us to chose from a wide range of different email types. Depending on what goal we want to reach with our newsletter, we can run individual campaigns, regular campaigns, auto responders (automated emails), A/B tests, RSS campaigns (mailings at pre-set times and frequencies) and follow-up campaigns.
Why do we use MailChimp on our website?
The reason we would use any newsletter service is so we can stay in contact with you. We want to keep you on the loop what news or attractive offers we have for you at the time. As we constantly seek out the easiest and best solutions for our marketing measures, we have decided on MailChimp as our newsletter management service. While the software is very easy to use, it offers many helpful features. For example, it allows us to create interesting and attractive newsletters in only a short time. With integrated design templates we can create every newsletter in an individual way. Due to the “responsive design” feature, our contents are also presented in a readable and pleasant way on your smartphone (or any other mobile device).
With tools such as A/B testing or the extensive analysis options, we can swiftly tell how you like our newsletters. This means that we can react if necessary and improve our offer or our services.
Another advantage is MailChimp’s “cloud system”. The data is not stored and processed directly on our server. We can retrieve the datafrom external servers and therefore save our memory space and also decrease maintenance effort.
What data is saved by MailChimp?
Rocket Science Group LLC (MailChimp) operate online platforms which enable us to get in contact with you, provided you subscribed to our newsletter. If you become a subscriber of our newsletter via our website, by email you agree to become a member of a MailChimp email list. Then, MailChimp saves your subscription data and your IP address, so it can verify your entry into the list provider. Moreover, MailChimp stores your email address, your name, your physical address and demographic information, such as language or location.
This information is used to send emails to you and to allow certain other MailChimp functions (e.g. the evaluation of newsletters).
MailChimp also shares information with third parties to improve its services. Moreover, MailChimp shares certain data with advertising partners of third parties to get a better understanding of its clients’ interests, in order to provide relevant contents and target-oriented advertising.
With so-called “web beacons” (small graphics in HTML emails), MailChimp can determine if an email has arrived, has been opened or if links have been clicked. This information is then stored on MailChimp’s servers. That way we receive statistical evaluations and can see how you liked our newsletter. Therefore, we can tailor our offer better to your wishes and improve our service.
Moreover, MailChimp are allowed to use this data for improving their own service. Thus, they can for example technically optimise the distribution or determine the location (or the country) of the recipient.
The following cookies can be set by MailChimp. The list is not exhaustive and is merely an exemplary selection:
Purpose: This cookie is necessary to provide the services of Mailchimp. It is always set when a user registers for a newsletter mailing list.
Expiry date: at the end of the session
Purpose: The cookie is used to differentiate a human from a bot. That way secure reports on the use of a website can be created.
Expiry date: after 2 hours
Purpose: This cookie comes from MasterPass Digital Wallet (a MasterCard service) and is used to offer a secure and easy virtual payment process to visitors. For this purpose, the user is anonymously identified on the website.
Expiry date: after 2 hours
Purpose: We could not find any further information about the purpose of this cookie.
Expiry date: after one year
How long and where is the data saved?
Since MailChimp is an American company, all retained data is stored on American servers.
Generally, the data stays permanently saved on MailChimp’s servers and is deleted only when you request it. You can have your contact information with us deleted. This permanently removes all your personal data for us and anonymises you in MailChimp’s reports. However, you can also request the deletion of your data permanently at MailChimp. Then all your data are removed from there and we receive a notification from MailChimp. After we receive the email we have 30 days to delete your contact from all integrations.
How can I delete my data or prevent data retention?
You can withdraw your approval for the receipt of our newsletters anytime, by clicking the link in the lower area of the received newsletter email. When you click on the unsubscribe link, your data with MailChimp gets deleted.
When you land on a MailChimp website via a link in our newsletter and cookies are consequently set in your browser, you can delete or deactivate these cookies anytime.
Depending on the browser, the deactivation or deletion differs slightly. The following instructions show how to manage cookies in your browser:
If you generally do not want to allow any cookies, you can set up your browser in a way so it would notify you whenever a potential cookie is about to be set. This lets you decide upon the placement of every single cookie.
MailChimp Data Processing Addendum
We entered a contract with MailChimp on the Data Processing Addendum. This contract serves as a protection of your personal data and ensures that MailChimp follows the applicable data protection regulations and disclose your personal data to third parties.
You can find more information on this contract at https://mailchimp.com/legal/data-processing-addendum/.
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?
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:
Purpose: The cookie is stored under the domain adform.net. It provides a uniquely assigned user ID that is generated automatically and collects data on the activity on our website.
Expiry date: after 2 months
Purpose: This cookie identifies if your browser accepts cookies. The cookie is stored under the domain track.adform.net.
Expiry date: after 1 month
Purpose: This cookie is saved under the domain track.adform.net. It stands for the client ID and is used to offer you improved advertisements. It can forward more relevant adverts to the user and helps to improve reports on campaign performance.
Expiry date: after 2 months
Purpose: The cookie is stored under the domain doubleclick.net. It serves the purpose of registering your actions following an impression or a click on the ad. Thus, it can be measured how our visitors like an ad.
Expiry data: after 1 month
Value: not specified
Purpose: With the „test_cookies“ it can be verified, if your browser even supports cookies. The cookie is saved under the domain doubleclick.net.
Expiry date: after 1 month
Purpose: It is saved under the domain adform.net. The cookie is placed upon your click on an ad. We could not find any further information on the use of this cookie.
Expiry date: after one hour
Note: This list does not claim to be exhaustive, as Google frequently change the choice of their cookies.
How long and where is the data stored?
Google retains your IP address, as well as various activities you perform on the website. Cookies store this information with the interactions on our website. According to Google, the company collects and saves the given information securely on its internal servers in the USA.
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.
