This privacy policy informs you about the type, scope, and purpose of the processing of personal data (hereinafter referred to as 'data') within our website and its associated web pages, features, and content. Regarding the terminology used, such as 'processing' or 'controller,' we refer to the definitions in Article 4 of the General Data Protection Regulation (GDPR).

6. Google Analytics

This website uses Google Analytics, a web analysis service of Google Inc. ('Google'). The information generated by the cookie about your use of this website is usually transferred to a Google server in the USA and stored there. In the case of activation of IP anonymization on this website, your IP address will be shortened by Google within member states of the European Union or in other contracting states of the Agreement on the European Economic Area.

7. Appointments with Microsoft Bookings

As part of our sales process, we use Microsoft Bookings for appointment scheduling, a service provided by Microsoft Ireland Operations Limited, One Microsoft Place, South County Business Park, Leopardstown, Dublin 18 D18 P521 (hereinafter: Microsoft). The use of this tool allows us to manage and coordinate customer appointments more easily. For this purpose, we collect the following data from you: Name, email address, phone number.

The connection to the service is established when you access the online booking function via a link in an email. The data you enter will be transmitted to Microsoft for the purpose of scheduling an appointment.

We have concluded a data processing agreement with the provider to meet data protection requirements. The provider's privacy policy can be found here. Since personal data is transferred to the USA, additional protective mechanisms are required to ensure the data protection level of the GDPR. To this end, we have agreed on standard data protection clauses according to Art. 46 para. 2 lit. c GDPR with the provider. These oblige the recipient of the data in the USA to process the data according to the protection level in Europe. In cases where this cannot be ensured even by this contractual extension, we strive for additional regulations and commitments from the recipient in the USA.

The legal basis for data processing in relation to the service lies in Art. 6 I lit. b GDPR if the appointment scheduling is aimed at concluding or performing a contract, or Art. 6 I lit. f GDPR for general inquiries, to provide you with a convenient appointment booking option at all times as part of our service offering.

Please note that the use of this service is voluntary and you can always arrange appointments via a separate channel.

The data will be deleted as soon as it is no longer required for the purpose. This does not apply to data that we must retain for a longer period due to legal requirements (e.g., commercial or tax law).
