The person responsible within the meaning of the EU General Data Protection Regulation (GDPR) is me: Cornelis Wiebering, Sch├╝tzenstrasse 4, 60311 Frankfurt am Main.

Your rights

You can exercise the following rights at any time using the contact details provided

  • Information about your data stored by me and its processing,
  • Correction of incorrect personal data,
  • Deleting of your data stored by me,
  • Restriction of data processing if I am not yet allowed to delete your data due to legal obligations,
  • Objection to the processing of your data by me, and
  • Data portability, provided that you have consented to the data processing or have concluded a contract with me.

Even if you have given me your consent, you can revoke it at any time with effect for the future.

Purposes of data processing

I process your personal data only for the purposes stated in this privacy policy. Your personal data will not be transferred to third parties for purposes other than those stated. I will only pass on your personal data to third parties if:

  • You have given your express consent to this,
  • the processing is necessary for the fulfilment of a contract with you
  • the processing is necessary to fulfil a legal obligation,
  • the processing is necessary to safeguard legitimate interests and there is no reason to assume that you have an overriding interest worthy of protection in your data not being passed on.

Deletion or blocking of data

I adhere to the principles of data avoidance and data minimisation. I therefore only store your personal data for as long as is necessary to fulfil the purposes stated here or for the various storage periods stipulated by law. Once the respective purpose no longer applies or these periods have expired, the corresponding data will be blocked or deleted in accordance with the statutory provisions.

E-mail, contact form and feedback form

If you contact me with questions of any kind by e-mail or feedback form, you give me your voluntary consent to contact you. This requires you to provide a valid e-mail address. This is used to allocate the enquiry and subsequently answer it. The provision of further data is optional. The information you provide will be stored to process the enquiry and for possible follow-up questions. Your personal data will be deleted upon request after your enquiry has been dealt with.

Changes to the privacy policy

I reserve the right to amend this privacy policy so that it always complies with current legal requirements or to implement changes to our services in the privacy policy, e.g. when introducing new services. The new privacy policy will then apply to your next visit.
