4. Google Fonts
This website loads fonts (Inter font family) directly from Google LLC servers upon each page visit:

When the fonts are loaded, your IP address is transmitted to Google servers.
Legal basis: Art. 6(1)(f) GDPR (legitimate interest in the consistent and technically sound presentation of the website).
Note: German courts have ruled that the transmission of IP addresses to Google by embedding external Google Fonts without user consent may violate the GDPR (cf. Regional Court Munich I, judgment of 20 January 2022 – 3 O 17493/20).
Third-country transfer: Google LLC is based in the USA and is certified under the EU–US Data Privacy Framework (DPF). The data transfer to the USA is therefore permissible on the basis of the European Commission’s adequacy decision of 10 July 2023 (Art. 45 GDPR).
