We store the data in data centres in Frankfurt am Main. For security reasons, the associated data backups are stored in other data centres within the EU and comply with the current requirements of the GDPR. The data is encrypted during transmission from the user to the server.
For the fulfilment of the contract, we use - like any online portal - the services of subcontractors who are listed in our AV contract, which is attached to the terms and conditions, and some of whom are based abroad. The current version can be accessed here.
