To apply and register for Das Klassentreffen, we collect various personal data. Usually, these are title, surname, first name, position, company and seniority level, functional area as well as contact data (e.g. e-mail address, LinkedIn profile). This data is referred to in the following as "participant data". We collect the participant data as part of the application process. Mandatory data are marked as such. We use your participant data to plan and organize the event (e.g. to the expected number of participants), invite you and to contact you in the course of communication if necessary. The legal basis for this data processing is Art. 6 para. 1 lit. b GDPR. We also collect information regarding your interest in networking at Das Klassentreffen to understand what participants will expect from this year’s Klassentreffen, improve the overall efficiency and experience of networking at the event and allow interested parties (us or partners of the event) to contact interested participants. You may also have the option of providing further information when registering (e.g. details of interests and wishes with which you can provide us with further details on your planned participation in the event). These data are summarised below as "voluntary data". We would like to meet your needs about your participation in Das Klassentreffen as best as possible and adapt our event optimally to the interests of the participants. The legal basis for this data processing is Art. 6 para. 1 lit. f GDPR, based on our common interest in an event that is as closely related as possible to the interests of the participants. We store the above-mentioned data in our contact database for future contact maintenance (see also Section 2.6 and 2.7) in connection with your existing data, if applicable.

We use the external service provider Eventbrite (Eventbrite Inc., 535 Mission Street, 8th Floor, 94105 San Francisco, CA, USA) for the onsite registration system and the payment for onsite tickets. We have concluded a data processing agreement with Eventbrite, Inc., pursuant to Art. 28 GDPR, to ensure that Eventbrite processes the data in accordance with our instructions and the European data protection principles. If Eventbrite transfers data to companies outside Europe (e.g. to the USA), Eventbrite has taken contractual precautions to ensure compliance with the European data protection principles. However, when personal data is processed outside Europe, it may in individual cases be the case that the rights of EU citizens cannot or cannot fully be enforced. You can revoke consent and withdraw your registration at any time.

In our newsletters, we use market-standard technologies to allow us to measure interactions with the email (e.g. opening of the email, which links are clicked on). We use this data for general statistical evaluations as well as to optimise and further develop our content and customer communication. This is done with the help of small graphics (pixels) embedded in the emails. The data is collected in pseudonymous form only and not linked to your other personal data. The legal basis for this is our aforementioned legitimate interest pursuant to Art. 6(1) lit. f GDPR. With our newsletters, our aim is to share content that is as relevant as possible for our users and to better understand what the readers are actually interested in. If you do not want your usage behaviour to be analysed in this way, you can unsubscribe from the newsletter at any time or disable the display of graphics in your email client by default. The data about how you interact with our newsletters is stored in pseudonymous form for 30 days before being completely anonymised.

2.3 Participation in the event
During Das Klassentreffen, we may use your participant data for organizational reasons (to determine your attendance or to contact you). The legal basis for this data processing is Art. 6 para. 1 lit. b GDPR.
2.4 Recordings
Recordings (photo and video) will be made during the event. This includes stream recordings for the online part of the event and recordings made by photographers and camera teams for the on-site part. We would like to ensure the possibility of documenting the event for internal purposes or the purpose of external presentations.
We would like to use the images and recordings taken in the context of our external presentation on our website and in our social media profiles (Facebook Fanpage, Twitter, LinkedIn, Xing, YouTube) in connection with the documentation of Das Klassentreffen. To do this, we first want to edit individual recordings (e.g. by selecting the image cut) and upload the edited recordings to the websites. The respective websites are freely accessible on the Internet and can therefore be accessed worldwide. The subpages of these websites, including any recordings, can be found via search engines. The providers of social media platforms process and use data that is posted on the platforms for their purposes if necessary. As soon as the content has been posted on the platforms, third parties (e.g. users of the platforms) can view, share, or download the content. In principle, recordings of speakers in the sessions will be published. Individual participants will only show up on the screen when they ask questions. Messages written to the chat will be shown to all speakers and participants in the session, with your name and title next to them, and might be read by the speaker during the session. There are also other networking features on the event platform, which allow you to interact with other participants, e.g. 1:1 video calls. These will also make your details available to other participants, but won’t be recorded or published.
You can contact us using the contact details given in section 1 and inform us that you wish to object to the use of the recordings on which you can be identified. The legal basis for this data processing is Art. 6 para. 1 lit. f GDPR, based on our legitimate interest in the documentation and advertising of our event as well as our external presentation. The recordings are usually published within a period of up to 48 months after the event.
2.5 Subsequent Klassentreffen updates
We will also use your participant data to provide you with further information on workshops, documents, or presentations from us or our speakers or further information on Das Klassentreffen. The legal basis for this data processing is Art. 6 para. 1 lit. b GDPR.
2.6 Future Klassentreffen events
We store the fact that you attended Das Klassentreffen this year in our contact database so that we can inform you by email about similar future events and the next Klassentreffen.
The legal basis for this data processing is Art. 6 para. 1 lit. f GDPR, based on our interest in advertising our future events. We store this data for the duration of our business relationship. If you do not wish to be contacted again, you have the right to object to this use of your data at any time. Please do not hesitate to contact us at any time using the contact details listed in section 1. You will also always find a link to unsubscribe in the emails.
3. Links to other websites and online content
Our website may contain links to websites and online content of other providers not affiliated with us. If you activate these links, we naturally no longer have any influence on which data is collected by the respective providers and which data they record. For more detailed information on data collection and use, please refer to the privacy policies of the respective providers. Since the collection and processing of data by third parties is beyond our control, we cannot assume any responsibility for this.
4. Disclosure of data
4.1 General information
We will pass on the data raised by us in the context of the registration or the event in principle only if:
- you have given your express consent according to Art. 6 para. 1 lit. a GDPR,- the disclosure according to Art. 6 para. 1 lit. f GDPR is necessary for the assertion, exercise, or defense of legal claims and there is no reason to believe that there is an overriding legitimate interest in not disclosing the data,
- we are legally obliged to disclose such information according to Art. 6 para. 1 lit. c GDPR or
- this is legally permissible and, according to Art. 6 para. 1 lit. b GDPR, necessary for the execution of contractual relationships with you or for the implementation of pre-contractual measures which are taken at your request,
- insofar as this is stated in these data protection notices (in particular concerning the publication of photo and video recordings on the social media platforms).
Also, the data may be passed on in connection with official inquiries, court orders, and legal proceedings if this is necessary for legal prosecution or enforcement.
4.2 External service providers
Some of the data processing described in these data protection notices may be carried out by our service providers. In addition to the service providers mentioned in this Privacy Policy, this may include, in particular, data centers that store our databases, IT service providers that maintain our systems, and consulting firms. If we pass on data to our service providers, they may only use the data to fulfil their tasks. The service providers have been carefully selected and commissioned by us. They are contractually bound to our instructions, have suitable technical and organizational measures at their disposal to protect the rights of the persons concerned, guarantee an appropriate level of data protection, and are carefully monitored by us. Some of our service providers may process your personal data outside the European Union or the European Economic Area. In these cases, we protect your personal data by ensuring that the requirements of Art. 44 et seq. GDPR are fulfilled.
5. Data Transfer to third countries
As explained in this privacy policy, we use services whose providers are partly located in so-called third countries (outside the European Union or the European Economic Area) or process personal data there, i.e. countries whose level of data protection does not correspond to that of the European Union. If this is the case and the European Commission has not issued an adequacy decision (Art. 45 GDPR) for these countries, we have taken appropriate precautions to ensure an adequate level of data protection for any data transfers. These include, among others, the standard contractual clauses of the European Union or binding internal data protection regulations.
Where this is not possible, we base the transfer of data on exceptions to Art. 49 DSGVO, in particular your express consent or the necessity of the transfer for the performance of the contract or for the implementation of pre-contractual measures.
If a transfer to a third country is provided for and there is no adequacy decision or suitable guarantees, it is possible and there is a risk that authorities in the respective third country (e.g. intelligence services) may gain access to the transferred data in order to collect and analyse it, and that the enforceability of your affected rights cannot be guaranteed.
6. Your rights
You have the right to request information about the processing of your personal data by us at any time. We will explain the data processing to you in the context of the provision of information and provide you with an overview of the data stored about your person. If data stored by us is incorrect or no longer up to date, you have the right to have this data corrected. You may also request that your data be deleted. Should deletion not be possible in exceptional cases due to other legal provisions, the data will be blocked so that it is only available for this legal purpose. You can also have the processing of your data restricted, e.g. if you believe that the data stored by us is not correct. You also have the right to data transferability, i.e. we can send you a digital copy of the personal data you have provided on request.
To exercise the rights described here, you can contact us at any time using the contact details listed in section 1 above. This also applies if you wish to receive copies of guarantees proving an adequate level of data protection.
Finally, you have the right to complain to the data protection supervisory authority responsible for us. You may exercise this right with a supervisory authority in the Member State of your residence, workplace, or alleged infringement. The competent supervisory authority is in Berlin: Berlin Commissioner for Data Protection and Freedom of Information, Friedrichstr. 219, 10969 Berlin.
Right of withdrawal and objection
According to Art. 7 para. 3 GDPR, you have the right to withdraw your consent to us at any time. The consequence of this is that we will no longer continue the data processing based on this consent in the future. The revocation of the consent does not affect the legality of the processing carried out based on the consent up to the revocation.
If we process your data based on legitimate interests according to Art. 6 para. 1 lit. f GDPR, you have the right according to Art. 21 GDPR to object to the processing of your data and to give us reasons which arise from your particular situation and which, in your opinion, indicate that your interests worthy of protection prevail. If you wish to object to data processing for direct marketing, you have a general right of objection, which we will also implement without stating reasons. Also, you will always find an unsubscribe link in our information emails on future events. Concerning the preparation of the photo and video recordings, you can also contact the photographer or cameraman at any time and inform them that you do not want any recordings of yourself. If you wish to exercise your right of withdrawal or objection, simply send an informal message to the contact details listed above.
