The legal basis for data processing is Art. 6 (1) (f) GDPR. The legitimate interest consists in an error-free function of the website. Microsoft Corporation has certified itself under the EU-US Privacy Shield Agreement (see

Microsoft uses so-called standard contractual clauses (= Art. 46 Para. 2 and 3 GDPR) as the basis for data processing by recipients based in third countries (outside the European Union, Iceland, Liechtenstein, Norway, i.e. in particular in the USA) or data transfer there. Standard Contractual Clauses (SCC) are templates provided by the EU Commission and are intended to ensure that your data also comply with European data protection standards if they are transferred to third countries (such as the USA) and stored there. Through these clauses, Microsoft undertakes to comply with European data protection standards when processing your relevant data, even if the data is stored, processed and managed in the USA. These clauses are based on an implementation decision of the EU Commission. You can find the decision and the corresponding standard contractual clauses here: []( /2021/914/oj?locale=en)
