Data Protection

1. General

The privacy of your personal data is very important to us. Therefore we would like to tell you about our use of cookies and analytics, and how we process your personal data.

"Personal data" is all information relating to an identified or identifiable natural person. Data pertaining to legal persons is not included in the term personal data.

We only collect personal data that you have disclosed to us. Further processing, in particular disclosure to third parties, only occurs if you have given your consent to this. This includes displaying the laying farms when the laying farm number is entered in the "Was steht auf dem Ei?" search form on our website and the list of KAT members, KAT system participants, KAT sponsoring members, approved KAT certification bodies and registered rearing farms on the internal section of our website.

Data controller

The data controller responsible for the privacy notice is the Association for Controlled Alternative Animal Husbandry (KAT) (Verein für kontrollierte alternative Tierhaltungsformen e.V. (KAT), Konrad-Zuse-Platz 5, 53227 Bonn, email:

2. Collection and use of your personal data

You are generally able to use our website without entering personal data.

However, we process your personal data if you send us a message using our contact form or by sending an email to us or our employees, for example to or to personalised email addresses used by our employees. The information (name, farm, telephone, email address) collected in the contact form and the data that we receive in your email and content of your message are used solely for the purpose of responding to your inquiry. The lawful basis for processing your personal data contained in emails (e.g. your email address) that you send to us is defined in Article 6 (1) (f) GDPR. The Regulation permits processing of personal data in the legitimate interest of the data controller except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject which require protection of personal data. As the Association is an organisation that is publicly recognised, it is important to us to be contactable by email for third parties. Your emails and the data they contain do not leave our email programme. We only use the data that we receive by email and the content of the message in order to respond to your inquiry. Data is stored only until the processing has been completed. The information is then deleted.

If the processing of your personal data is required in order to fulfil a contract to which you are party (e.g. your participation in the KAT system or when using our database and entering your user data for this purpose by you) or to carry out pre-contractual measures, the data subject's personal data may be processed without consent pursuant to Article 6 (1) (b) GDPR. In this case too, we only keep your data for as long as is required to complete the contract and in respect of any guarantee obligations. Please bear in mind that our KAT participation agreements are long-term obligations that are designed to endure for many years. If personal data is processed to fulfil a contract or carry out pre-contractual measures, we will generally delete this after expiry of the usual retention period of three years following the end of the contract pursuant to Section 195 BGB. According to the provisions of Section 199 para. 1 BGB, the usual retention period generally starts at the end of the year in which the claim arose and the creditor became aware or ought to have become aware in the absence of gross negligence of the circumstances pertaining to the claim and the identity of the debtor.

If we are subject to a statutory requirement to store or retain your data (e.g. in the case of business or commercial correspondence), we may retain it for longer periods of up to ten years.
