The most important rule on data protection in an interview is to discuss the recording, storage, further use, publication and deletion of the data and content in a transparent way. A corresponding data protection agreement should contain: - Name of the interviewee - Details of the interviewer - Purpose of the work, intended use of the data - Consent to use the (possibly anonymised) data for the intended purpose - Type of anonymisation of the data and care regarding data security - Type of recording - Way of passing on the data (e.g. to university) - Place and duration of storage
