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. We will not pass your data to third parties, except you register for an event DECHEMA Ausstellungs-GmbH is organizing in cooperation with other partners or by utilizing external service providers. In such a case we normally will transmit your registration data to our cooperation partners.  As far as it is required for the realization of an event or to fulfill your request data may be transfered to associated affiliates, organizations or external service providers, too. If data are transfered to third parties in accordance to the above announced regulations, we oblige these parties to operate within the rules of the EU General Data Protection Regulation (EUDataP). If you register for an event which is part of a series of events, that are organized by altering national or international organizers, DECHEMA Ausstellungs-GmbH will usually pass your adress and/or contact data to the next organizer of this event series. As far as we are obligated legally or by court order, we will convey your data to information-entitled governmental authorities.

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 the company re-lounge GmbH with its tool inxmail for sending and administering our newsletters. For accounting and printing of tickets as well as for the service “personalized ticket” we work together with the Messe Frankfurt Venue GmbH. For analysis and optimization of our web services we are using Google Analytics. 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 you redeem a voucher in order to receive a free ticket, we will pass on your contact details (name, address and e-mail) to the voucher issuer (usually an exhibitor). By redeeming the voucher, you automatically declare your consent to the transfer and use of your data by the exhibitor. We have no further influence on the use of your data by the voucher issuer. If you do not wish this data transfer, you must purchase a ticket for a fee without using a voucher code.

In some places of our website you can contribute within forums or register into catalogs. These contributions in our forums and/or catalogs are accessible for everyone. Therefore one should examine a contribution carefully before the publication whether it not contains data, which are not intended for the public. One must assume, that Internet search machines view those contributions. Therefore this contribution may be world-wide accessible without visiting our website initially. In case of foreign operators the deletion or correction of such entries often cannot be accomplished.

What data does my personalized ticket contain?

An essential guiding principle of the trade fairs we organize is to promote the exchange of information at all levels. In order to make it as easy as possible for you as a visitor to get in touch with the exhibitors you are interested in, we will provide you with a personalized admission ticket. This contains a machine-readable barcode that can be used to uniquely identify you and serves as an electronic business card during your visit to the trade fair.

Exhibitors can "scan" the barcode on your admission ticket to access your contact details and use them to deepen the initial contact. By handing over your personalized admission ticket to the exhibitor for "scanning", you agree to the transfer of your data to the exhibitor. The process is comparable to the handing over of a printed business card and is therefore a deliberate decision on your part. We only provide you with the technical service. We have no influence on the further use of your data by the receiving exhibitor.

What other rights do I have?

a) Rights of access, rectification, deletion and objection

As provided in Article 14-17 of the EU-GDPR we inform you about your rights of access, rectification, deletion and limitation of your processing data. You have the right to request from the controller access to and rectification or erasure of personal data or restriction of processing concerning the data subject or to object to processing as well as the right to data portability.

b) Right of withdrawal

Your right to withdraw consent at any time, without affecting the lawfulness of processing based on consent before the withdrawal.

c) Right of appeal

Lodge a complaint with a competent supervisory authority is always possible.
