Some data are generally required in order to use the website. The data are stored in a so-called Cookie (a small text file on your computer). The data contain a session ID, a unique and anonymous user ID combined with a key to technically answer individual queries from you (user_data). Another security key (csrf) is also saved to prevent common online attacks. These fields consist of alphanumeric strings that do not contain any information about you as a person. One exception is that we save the IP address of too many requests to our system so that we can identify malicious use and errors. In addition, a technical field is saved (singletab) to ensure that some actions are only carried out in the active browser tab (e.g. opening a game). We use local storage to record the difference between your system time and the server time so that we can show you correct time information. We measure how our website is used so that we can better decide which features to develop next and how we can further improve the user experience. To do this, we send statistics on page views and actions to Google Analytics. The data has no direct reference to your user or your person other than the IP address and your Google Analytics identifiers. You can activate other data processing functions. Your personal selection is also saved locally.
We offer a whole range of personal settings for more convenience on our website. The options include, for example, who you would like to play against online, your preferred chessboard and piece designs, the preferred size of the board, the volume of the video player, your preferred language, whether you prefer to use chat or chess notation and much more . You can use this page without making or saving settings, but if you want us to remember which settings you make, we strongly recommend that you activate this function. This function is essential for registered, logged-in users in order to also save data on your privacy settings, blocked users and your friendships on chess24.
Social media data

In order to enable us to offer free services, we would like to ask you to accept personalized advertising from our advertising partners. If you activate this function, data from the advertisers may be collected and stored, in return you will receive more relevant advertising content and we can invest more in free functions and content.

For registered users, we store more information such as your profile, which you can view and change at any time, your chess games, your analyzes, forum content, chats and messages, your friends and blocked users and content or subscriptions that you have taken out. You can find all the data in your personal profile. A free registration is not required to use this website. If you contact our support team, a ticket will be created with your name and email address so that we can answer you. This data is processed by the service provider Zendesk. If you have subscribed to a newsletter or are a registered member, we will be happy to send you the latest news from time to time. You can unsubscribe from a newsletter at any time and, as a registered member, make more detailed settings for the emails that we send in your profile. For newsletters, we temporarily transfer your email address and user name to the service provider Mailchimp. If you purchase content or subscriptions, we work with the payment provider Adyen, who collects and evaluates your payment data and data about the payment process (e.g. to prevent fraud).
