Definition of terms in accordance with Art. 4 GDPR

‘Personal data’ is all information that relates to an identified or identifiable natural entity (e.g. name, address, telephone number, date of birth, e-mail address or usage behaviour).

‘Processing’ means any operation or set of operations, with or without the aid of automated methods, in connection with personal data, such as the collection, recording, organisation, ordering, storage, adaptation or alteration, read-out, querying, usage, disclosure through transmission, distribution or other form of provision, comparison or linkage, restriction, deletion, or destruction.

The ‘controller’ is the natural or legal person, public authority, agency or other body which, alone or jointly with others, determines the purposes and means of the processing of personal data.

Collection of personal data

The following personal data of visitors and users is regularly collected during use of our online offer and our services:

-          Usage data (e.g. device information, IP addresses)

Purpose of processing and legal basis

We process your personal data for the following purposes:

-          Provision of an online offer (incl. functions and content)

When the website is used for purely informational purposes, i.e., when you do not register or transfer any other information to us, we collect the following data in order to display our website to you and to guarantee stability and security (the legal basis is Art. 6, Section 1, p. 1 lit. f GDPR):

  • Operating system and its interface

The above data (or ‘log files’) is stored for a maximum of 30 weeks for security reasons and for the detection of faults. The log files are then deleted. If, however, the storage of this information is required for the purpose of providing evidence (e.g. during investigation into misuse or fraud), it is not deleted until the investigation of the respective incident has been concluded.

-          The provision of contractual performances

In order to fulfil the contract or implement pre-contractual measures, personal data such as basic data and contractual data is processed (legal basis, Art. 6 Section 1 lit b) GDPR).

-          Contact enquiries

If you contact us (e.g., by e-mail, telephone, contact form, or social media), your data will be processed in order to process the contact enquiry and its implementation (legal basis Art. 6, Section 1 lit b) GDPR).

If your enquiry is no longer necessary, we will delete it unless statutory storage periods apply. We check the necessity every three months. The statutory storage periods continue to apply.

Cooperation with order processors and third parties

Your personal data is only disclosed, transferred or otherwise provided for access to third parties on the basis of a statutory permission (e.g. for the fulfilment of contract, following your consent, on the basis of our justified interests or in cases of legal obligation).

If third parties are commissioned with the processing of data on the basis of an order processing contract, they may only process this personal data according to our instructions, in accordance with Art. 28 GDPR.

Third country transfer

It is ensured that before forwarding personal data, either a suitable data protection level exists, or there is an agreement of so-called EU standard contractual clauses of the European Union between dena and the recipients, and/or sufficient approval has been provided by the data subject.
