Gathering and processing personal data

What are your rights?

You have various rights under the terms of the General Data Protection Regulation. Specific rights particularly arise from Articles 15 to 18 and 21 of the General Data Protection Regulation.

The right to information

You can request information about the personal data we have processed. You should precisely state your request in your application for information to make it easier for us to compile the required data. Accordingly, details on the specific administrative procedure and the procedural stage should be provided in the application to the greatest extent possible. In the event of manifestly groundless or excessive applications, the provision of information can be refused.

The right to rectification

If the information in question is not (or no longer) applicable, you can request to have it rectified. You also have the right to have incomplete personal data completed.

The right to erasure

You can ask for your personal data to be erased. Among other things, your right to erasure depends on whether the data in question is still needed in order to comply with our legal duties.

The right to restriction of processing

You have the right to request the restriction of any processing of data concerning you. The restriction is not an obstacle to the processing of the data, insofar as there is significant public interest in the processing of this data.

The right to object

You have the right to object to the processing of the data in question at any time, for reasons arising from your particular situation. However, we are unable to meet this request if there is overwhelming public interest in the processing of this data or a legal regulation compels us to process it.

The right to complain

If you are of the opinion that we have failed to comply with your request in any way, you can lodge a complaint with the relevant data protection supervisory authority. You can find the contact details of the data protection authorities at national and regional state level at
