Because you have a business relationship with us (current contract) we process your data based on article 6.1 a-c of the EU-GDPR:

  • Usage data such as connection history (pseudonymized over IP address): 1 year

Do we carry out profiling?

If you have not created an interest profile within your account, we will try to determine your interest profile from the events you have attended. This is done by thematically categorizing the respective event and comparing it with your automatically created interest profile. You can help us a great deal by comparing the interest profile associated with your account with your personal areas of interest.

Do we pass your data to third parties?

Within the DECHEMA Group (DECHEMA e.V., DECHEMA Research Institute, DECHEMA Ausstellungs-GmbH) we use your data to inform you about services and products that fit your needs. We guarantee that we will always process your personal data in accordance with the provisions of the applicable data protection laws. You should be aware of the fact that you can object to the analysis or use of your personal data for these purposes at any time.

We are using a number of external service providers and also cloud service providers to help us to deliver our event and IT services. These are for example the Lombego Systems GmbH with the conference management system Converia or the Newsletter2Go GmbH with its newsletter tool of the same name. All of these service providers have been carefully selected by us and contractually committed to the careful observance of all relevant data protection regulations. At the same time, of course, we only pass on the minimum amount of data required to use these services.

If we perform an event together with an external organizer, we pass all relevant data to the external organizer in order to carry out the event. If you take part in an event from a series of events with –typically international - changing organizers, we will normally pass your contact data to the next organizer of this event series, unless you have objected to the disclosure of your data when registering for this event.
