Mainz.de, the Mainz.de microsites, and the Mainz.de event database use images from various photographers and image databases. The authors and image sources are usually named directly next to the respective image. For technical reasons, the mandatory link to the image database www.pixelio.de is provided centrally at this location.

Mainz.de and the Mainz.de microsites use map material from the Mainz city administration's geoinformation system based on OSM background maps to display the city map and specialist applications.

The maps from the Federal Agency for Cartography and Geodesy are used for the maps with address data.

The foreign-language pages on mainz.de were generated using AI. The DeepL Pro translation service is used, which automatically translates all content using AI and makes it available in multiple languages on the city’s web server. DeepL Pro is a product of DeepL SE, Maarweg 165, 50825 Cologne.

Machine translations may not fully correspond to the original text. The State Capital of Mainz assumes no liability for the accuracy, completeness, or timeliness of the translations. Furthermore, there is no guarantee that all content on mainz.de will be fully translated —for example, applications integrated as i-frames (such as “Lost and Found Online”), content embedded via interfaces (such as the events calendar), and files (e.g., PDFs, images, graphics) may not be translated. No liability is assumed for damages resulting from missing, incomplete, or incorrect translations. Machine translation does not replace manual translation by certified linguists.

When accessing the pages, personal data remains anonymous, as no data is transmitted to the service provider. The translated content is stored locally on the web server of the State Capital of Mainz and made available directly from there.
