General
Matheeule.de is a largely static website. No cookies are set, and there is no analysis or tracking of user behaviour. Personal data is only processed to the extent technically necessary, as described below.
Hosting and server log files
This website is hosted by an external service provider ([Please add: name and address of the host]). When the pages are accessed, the hosting provider collects technically necessary access data in server log files (in particular the IP address, date and time of the request, the page accessed, the amount of data transferred, and the browser type and operating system). This processing takes place to ensure secure and stable operation on the basis of our legitimate interest pursuant to Art. 6 (1) (f) GDPR.
Google Fonts
To display fonts consistently, this website embeds fonts from Google Fonts, which are loaded from Google servers (fonts.googleapis.com and fonts.gstatic.com). When a page is accessed, your browser loads the required fonts directly from Google and thereby transmits your IP address to Google. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. The legal basis is our legitimate interest in a consistent presentation pursuant to Art. 6 (1) (f) GDPR. You can find more information in Google's privacy policy at https://policies.google.com/privacy.
External scripts (jsDelivr CDN)
On the certificate pages the program library „pdf-lib“ is loaded via the content delivery network jsDelivr (cdn.jsdelivr.net) in order to create the certificate directly in the browser. Your IP address is transmitted to the operator of the CDN. The legal basis is Art. 6 (1) (f) GDPR. The name you enter is processed exclusively locally in your browser and is not transmitted to a server.
Your rights
You have the right at any time to access (Art. 15 GDPR), rectification (Art. 16 GDPR), erasure (Art. 17 GDPR), restriction of processing (Art. 18 GDPR) and data portability (Art. 20 GDPR). You also have a right to object (Art. 21 GDPR) and a right to lodge a complaint with a data protection supervisory authority. Please use the contact details given above.
