Google reCaptcha

We use the Google reCaptcha service to determine whether a person or computer makes a particular entry in our contact or newsletter form. Google uses the following data to determine whether you are a human being or a computer: IP address of the terminal device used, the website that you visit on our site and on which the captcha is embedded, the date and duration of the visit, the identification data of the browser and operating system type used, Google account if you are logged in to Google, mouse movements on the reCaptcha areas and tasks for which you must identify images. The legal basis for the data processing described is Art. 6 Para. 1 lit. f of the Basic Data Protection Regulation. There is a legitimate interest on our part in this data processing to ensure the security of our website and to protect us from automated inputs (attacks).

Our hosting provider 1&1 IONOS SE uses the CDN service of Cloudflare Inc. ("Cloudflare"), 101 Townsend St., San Francisco, California 94107, USA, to make our website faster and more secure. A Content Delivery Network (CDN), as provided by Cloudflare, is a network of servers connected over the Internet to deliver websites to users' screens faster. In simple terms, Cloudflare creates copies of our Smart Calculator files and places them on its own servers. When the smart calculators are called up, the system ensures that they are delivered by the server that can display the smart calculators the fastest. Thus, the smart computers are not only delivered by Cloudflare from our hosting server at 1&1, but from servers all over the world. The Cloudflare servers, like 1&1 IONOS SE, also store server log files. Cloudflare processes this data as part of the services in compliance with the applicable laws. This of course also includes the German Data Protection Ordinance (DSGVO).

JavaScript libraries

JavaScript libraries are used in this website to display some elements and for certain interactive functions, which are downloaded by the browser as a separate file. These JavaScript libraries are very widespread and are used by many websites on the Internet. Therefore we have not stored these libraries on our server, but use identical files from a Content Delivery Network (CDN). This makes the pages load faster from smart machines, because most websites that use the same JavaScript libraries also use the same CDN. This means that your browser does not have to reload the corresponding JavaScript libraries if you have previously visited websites that have already loaded the same library and thus cached it in your browser. This is a great advantage, especially when accessing websites with mobile devices.

However, the integration of JavaScript libraries via a CDN results in data being retrieved from a server of the CDN operator when the website is called, so that this server or its operator at least obtains knowledge of your IP address. Without your IP address, the server could not send the respective JavaScript library to your browser, which is why the IP address is required to retrieve the JavaScript file.

In addition, the CDN server and its operator usually also learn that you have accessed the JavaScript file via our website and some technical information about your browser, since almost every web browser automatically sends this data to the server each time you access it. Some browsers allow you to restrict or modify the data transmitted to the server, but whether this is possible depends on the browser manufacturer. Even if the CDN operator only needs the transmitted information, in particular the IP address, to deliver the retrieved content, it is beyond our knowledge and influence whether and to what extent the operator also statistically evaluates or stores this information.
