Rights of Data Subjects under KDG

If your personal data is processed by us, you are a data subject within the meaning of KDG and you have the following rights against us as the data controller:

Right to information

You have the right to request confirmation from the data controller of whether personal data concerning you is being processed by us.

If such processing is taking place, you can request information from the data controller about this information.

Right to rectification

You have the right to request the data controller to correct and/or complete any personal data concerning you if it is incorrect or incomplete. The data controller must make the correction without delay.

Right to restriction of processing

Under the legally defined conditions, you can request the restriction of processing of personal data concerning you:

If the processing of the personal data concerning you has been restricted, these data may – apart from their storage – only be processed with your consent or for the establishment, exercise or defense of legal claims or for the protection of the rights of another natural or legal person or for reasons of important public interest of the Union or of a Member State.

If the restriction of processing has been restricted under the above conditions, you will be informed by the data controller before the restriction is lifted.

Right to erasure

You can request the data controller to erase personal data concerning you without delay, and the data controller is obliged to erase this data without delay if one of the legally regulated reasons applies.

If the data controller has made the personal data concerning you public and is obliged to erase it in accordance with para. 1 KDG, the data controller, taking account of available technology and the cost of implementation, shall take reasonable steps, including technical measures, to inform other controllers who process the personal data that you have requested the erasure by such controllers of any links to, or copy or replication of, those personal data.

If erasure is not possible or only possible with disproportionate effort due to the special nature of storage, the right to erasure shall be replaced by the right to restriction of processing pursuant to § 20 KDG. This does not apply if the personal data have been processed unlawfully. Blocking and the entry of a blocking notice shall also be considered as restriction of processing.

Right to notification

If you have exercised your right to rectify, erase or restrict the processing vis-à-vis the data controller, the data controller is obliged to notify all recipients to whom the personal data concerning you have been disclosed of this rectification or erasure of the data or restriction of processing, unless this proves impossible or involves a disproportionate effort.

You have the right to be informed by the data controller about these recipients.

Right to data portability

You have the right to receive the personal data concerning you that you have provided to the data controller in a structured, commonly used and machine-readable format. You also have the right to transmit this data to another data controller without hindrance from the data controller to whom the personal data were provided.

In exercising this right, you also have the right to have the personal data concerning you transmitted directly from one data controller to another, where technically feasible. This shall not adversely affect the freedoms and rights of others.

The right to data portability shall not apply to processing of personal data that is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the data controller.

Right to object

You have the right to object, on grounds relating to your particular situation, at any time to processing of personal data concerning you that is based on § 6 para. 1 lit. f or g KDG; this also applies to profiling based on these provisions.

The data controller shall no longer process the personal data concerning you unless the data controller can demonstrate compelling legitimate grounds for the processing which override your interests, rights and freedoms or for the establishment, exercise or defense of legal claims.

If the personal data concerning you are processed for direct marketing purposes, you have the right to object at any time to processing of personal data concerning you for such marketing, which includes profiling to the extent that it is related to such direct marketing.

If you object to processing for direct marketing purposes, the personal data concerning you will no longer be processed for such purposes.

Right to lodge a complaint with the supervisory authority

You also have the right to lodge a complaint with the supervisory authority in accordance with § 48 KDG. The competent data protection authority for the responsible body has been mentioned above.
