Where the processing of personal data relating to you has been restricted, such data may only be processed - apart from being stored - with your consent or for the establishment, exercise or defence of legal claims or for the protection of the rights of another natural or legal person or for reasons of substantial public interest of the Union or a Member State.

13.4 Right to erasure

13.4.1 You may request the data controller to erase the personal data concerning you without undue delay and the data controller is obliged to erase such data without undue delay if one of the following reasons applies:
(a) the personal data concerning you are no longer necessary for the purposes for which they were collected or otherwise processed.

In exercising this right, you also have the right to have the personal data concerning you transferred directly from one controller to another controller, insofar as this is technically feasible. This must not affect the freedoms and rights of other persons.

13.8 Right to revoke the declaration of consent under data protection law

13.9 Automated decision-making in individual cases including profiling
You have the right not to be subject to a decision based solely on automated processing - including profiling - which produces legal effects vis-à-vis her or similarly significantly affects her. This does not apply if the decision
a) is necessary for the conclusion or performance of a contract between you and the controller,
(b) is permissible under Union or Member State law to which the controller is subject and that law contains adequate measures to safeguard your rights and freedoms and your legitimate interests; or
(c) is made with your express consent.
However, these decisions may not be based on special categories of personal data pursuant to Art. 9(1) DS-GVO, unless Art. 9(2)(a) or (g) applies and appropriate measures have been taken to protect the rights and freedoms as well as your legitimate interests.

As a matter of principle, data will not be passed on; any exceptions are regulated in the above points. In particular, the data will not be passed on for commercial purposes (address trading).

15. Legal basis for processing

Insofar as we obtain the consent of the data subject for processing operations involving personal data, Article 6(1)(a) of the EU General Data Protection Regulation (GDPR) serves as the legal basis.
When processing personal data that is necessary for the performance of a contract to which the data subject is a party, Article 6(1)(b) DSGVO serves as the legal basis. This also applies to processing operations that are necessary for the performance of pre-contractual measures.
If processing of personal data is necessary for compliance with a legal obligation to which our company is subject, Article 6(1)(c) DSGVO serves as the legal basis.
In the event that vital interests of the data subject or another natural person make processing of personal data necessary, Article 6(1)(d) DSGVO serves as the legal basis.
If the processing is necessary to protect a legitimate interest of our company or a third party and if the interests, fundamental rights and freedoms of the data subject do not override the first-mentioned interest, Article 6(1)(f) DSGVO serves as the legal basis for the processing. The legitimate interest of our company lies in the performance of our business activities.

16. Duration of the storage of personal data

Personal data is stored for the duration of the respective statutory retention period. After expiry of this period, the data is routinely deleted, unless it is necessary for the initiation or fulfilment of a contract.
