1. Subject matter of the contract

Participation in custlab serves the purpose of market and opinion research in return for payment. For the purpose of executing the contract custlab will collect different personal data of the Participant. custlab is commissioned by various companies (custlab's customers) to conduct surveys and / or product tests. Here, customers request specific target groups on which the survey and / or the product test should be aimed at. custlab will group Participants according to specific target groups in aggregated form. Using this data - without the customer being able to establish a personal reference to the Participant - the Participant will be designated from time to time by e-mail to participate in surveys and / or to participate in product tests in exchange for remuneration. The results of these surveys will be transmitted by custlab to its customers without any personal reference being established. Participation in custlab without providing specific personal data is therefore not possible. custlab will be unable to select the Participant for certain surveys and / or product tests without the provision of certain personal data. You can find more details on the collection and storage of your personal data in our Privacy Policy ( and in the respective Declarations of Consent.
