Right to Data Portability
You have the right to have data that we process automatically on the basis of your consent or in fulfillment of a contract handed over to you or to a third party in a common, machine-readable format.

You have the right to request restriction of the processing of your personal data. For this, you can contact us at any time. The right to restriction of processing exists in the following cases:
- If you dispute the accuracy of your personal data stored by us, we usually need time to verify this. For the duration of the verification, you have the right to request restriction of the processing of your personal data.
- If the processing of your personal data has been/is unlawful, you can request restriction of data processing instead of deletion.
- If we no longer need your personal data, but you need it for the exercise, defense, or assertion of legal claims, you have the right to request restriction of the processing of your personal data instead of deletion.
