Legal Basis and Purposes

Our legal basis for collecting and using the personal data described in this Privacy Policy depends on the personal data we collect and the specific purposes for which we collect it.

In short, we use the personal data we collect to provide, analyse and improve the Platform and our services; to increase the security of the Platform; and to give you the best possible experience. In addition, we use pseudonymised data to create advertising target groups.

Your personal data will be deleted or anonymised when it is no longer relevant for the stated purposes, and there are no longer any retention obligations.

Service Providers and Data Transfers

We may employ third party companies (“Service Providers“) to facilitate the operation of our Platform, assist us in analysing how our Platform is used, or perform Platform-related services, such as payment, delivery or IT infrastructure services. These third parties have access to your personal data only and insofar as necessary to perform these tasks on our behalf and are required to safeguard it in accordance with our contractual obligations and applicable data protection legislation.

Such safeguards may include transfer to countries that have been deemed to provide an adequate level of protection according to lists of countries published by the Federal Data Protection and Information Commissioner; applying standard data protection model clauses, binding corporate rules or other standard contractual obligations which provide for appropriate protection of data.

We also take internal data privacy very seriously. Our employees and the Service Providers are required to maintain secrecy and comply with applicable data protection legislation. In addition, they are granted access to personal data only insofar as this is necessary for them to carry out their respective tasks or mandate.

The security of your personal data is important to us but remember that no method of transmission over the Internet or method of electronic storage is fully secure. While we strive to use commercially acceptable means to protect your personal data, we cannot guarantee its absolute security. We recommend that you use antivirus software, a firewall, and other similar software to protect your system.
