Principles of Data Collection
Anyone who takes part in a competition or a promotion must necessarily provide data for this purpose, as otherwise a possible prize could not be allocated. On the other hand, companies also like to organise competitions for this very reason. For them, this offers the opportunity to collect addresses and the like in order to either use them themselves for advertising purposes or to sell them at good prices.
However, since information such as names, addresses and e-mail addresses are personal data, data protection must be respected in a competition. The information of the participants cannot be used by the company at will. Rather, the collection, storage and processing of data is subject to the legal requirements for data protection.
The fact that competitions require information is not a problem in itself. However, as a first step, the organiser should bear in mind that only the information that is actually needed for the implementation is collected. The principle of data minimisation must therefore be observed.
Furthermore, the data collected for participation in the competition may only be used for this purpose, so that data protection is not violated. This is the principle of purpose limitation, which prohibits the use of data for purposes other than those stated.
In the case of a competition, a privacy notice should transparently explain what information is stored for what purpose and how it is processed.
