In order for this internet portal to function properly, we sometimes store small files – so-called cookies – on your device. This is common for most major websites.
What are cookies?
A cookie is a small text file that a web portal leaves on your computer, tablet computer or smartphone when you visit it. In this way, the portal can "remember" certain entries and settings (e.g. login, language, font size and other display preferences) over a certain period of time and you do not have to make them again on each subsequent visit and when navigating in the portal.
How do we use cookies?
Ideas These cookies are used to store information on our websites about how the website is presented, such as your preferred language or region. For example, if your region has been saved, a website will show the local weather forecast or local traffic news. These cookies also allow you to personalize the font size and type and other areas of the website. Losing the information in a preference cookie may make the website more difficult to use, but typically does not result in an outage. Most Google users' browsers have a preference cookie called "PREF". A browser sends this cookie with requests to Google websites. The PREF cookie may store your preferences and other information, in particular your preferred language (e.g. English), how many search results to show per page (e.g. 10 or 20) and whether the Google SafeSearch filter is activated should.
Security We use security cookies to authenticate users, prevent fraudulent use of credentials and protect user data from unauthorized access. For example, we use so-called SID and HSID cookies, which record the Google account ID and the last login time of a user in digitally signed and encrypted form. The combination of these two cookies allows us to block many types of attacks. For example, we stop attempts to steal information from forms you fill out on websites.
processes Process cookies help a website respond properly and provide expected services. This includes navigating websites and accessing protected areas of the website. A website will not function properly without these cookies. For example, we use a cookie called "LBCS" which allows Google Docs to open multiple documents in a browser. If this cookie is blocked, Google Docs cannot run correctly.
Advertising We use cookies to make ads more engaging for users and more valuable for publishers and advertisers. Cookies are commonly used to select ads relevant to the user, to improve reporting on campaign performance, or to prevent a user from seeing the same ads multiple times. Google uses cookies like the PREF, NID or SID cookie to customize ads on Google products like Google Search. For example, we use cookies to record your most recent searches, your past interactions with an advertiser's ads or search results, and your visits to an advertiser's website. In this way, you receive individually tailored advertising on Google. We also use cookies for ads that we serve across the web. Our main ad cookie for non-Google websites is called "ID". It is stored in browsers under the domain. We also use other cookies, e.g. "_drt_", "FLC" and "exchange_uid". Sometimes a cookie is set for the domain of the website visited. Our DoubleClick product may set a cookie called "__gads" for the domain of the website visited. Other Google products like YouTube may also use DoubleClick cookies to serve more relevant ads. Learn more about ads and YouTube Google also uses conversion cookies, which primarily allow advertisers to measure how many of the people who click on their ads end up buying their products. These cookies enable Google and the advertiser to determine that you clicked on the ad and then visited the advertiser's website. Conversion cookies are not used by Google to target interest-based ads and are only stored for a certain period of time. These cookies are generally set in the domain or in the domain. Data from conversion cookies may also be used in connection with your Google account to link conversion events for your different devices. However, only anonymous conversion data extracted from these cookies is shared with advertisers. Some of our cookies can also be used to measure conversion events. For example, DoubleClick and Google Analytics cookies can be used for this purpose and set in the domain of the website you are visiting.
session status Websites often collect information about how users interact with a website. This includes, for example, which pages users visit most often and whether they receive error messages from certain pages. We use these so-called "session status cookies" to optimize our services and thus improve browsing for our users. However, blocking or deleting these cookies will not affect the use of the website. These cookies can also be used to anonymously measure the effectiveness of PPC (pay per click) and affiliate ads. For example, we use a cookie called "recently_watched_video_id_list" that YouTube uses to track the videos that were last watched in a specific browser.
Analytics Google Analytics is Google's analysis tool that gives website and app owners insights into how their users interact with the resources on offer. Google Analytics may use certain cookies to collect data and report website usage statistics without obtaining any information that would make individual users personally identifiable to Google. In addition to sharing usage statistics, the Google Analytics pixel tag, along with some of the advertising cookies described above, may also help deliver more relevant ads on Google products, such as Google Search, and across the web.
