Note on data transfer to the USA

Among other things, we use tools from companies based in the USA or other third countries that are not secure in terms of data protection law. If these tools are active, your personal data can be transferred to these third countries and processed there. We would like to point out that no data protection level comparable to that in the EU can be guaranteed in these countries. For example, US companies are obliged to hand over  personal data to security authorities without you, the data subject, being ablte to  take legal action. It can therefore not be ruled out that US authorities (e.g. secret services) process, evaluate and permanently store your data on US servers for monitoring purposes. We have no influence on these processing activities.
