During or after the event, OCF might contact you to collect your feedback about your experience, ascertain event impact or manage a post-event collaboration.

If your personal data is to be shared with a third party, sponsors, exhibitors, it will be clearly specified on the event website or invitation. To understand how a third party will use your data, OCF will provide you a link to the third party’s Data Protection statement or otherwise inform you how to obtain a copy of it.

    We provide and support some of our services through contractual arrangements with service providers and other third parties. OCF and our service partners use your personal data to operate our website(s) and provide services and events to you.

    The personal information OCF collects from you is stored in one or more databases hosted by third parties that may be located within the EU or outside the EU. These third parties do not use or have authority to access to your personal data for any reason other than cloud storage and retrieval.

    We will also disclose personal data in the following circumstances:

    • if we are required or permitted to do so by law, regulatory or other legal process;
    • to protect our rights, reputation, property or the safety of us and others;
    • to defend or enforce our rights or your obligations.

    We do not sell personal information to anyone or share it with third parties who are facilitating the delivery of other services.

    Transferring personal data from the EU

    OCF is headquartered in The Netherlands (NL), and our services are run mostly from there (NL), as well as from France (FR), Germany (DE) and Poland (PL), all inside the EU. Personal data we collect about you will generally be processed in these locations. OCF endeavours to apply suitable safeguards to protect the privacy and security of your personal data and to use it only within the authorisation you have given and the practices described in this Data Protection statement.

    In some cases, OCF may transfer your personal data to countries outside the EU, for example if we use a third party for processing services or storing data or for obtaining feedback on one of the services or events we provide. If we do transfer personal data to third countries, we will ensure that such transfers are compliant with our obligations under relevant data protection legislation and that appropriate technical and operational controls are in place to keep your personal data secure.

    If personal data is transferred from the EU to the USA, the EU-US Privacy Shield will be used. This framework was developed to enable companies to comply with data protection requirements when transferring personal data from the EU to the USA.

    • there are security and privacy limitations on the Internet which are beyond our control;
    • the confidentiality, integrity and availability of any and all information exchanged using these services cannot be 100% guaranteed;
    • we cannot be held accountable for activity that results from your own neglect to safeguard the security of your login credentials and equipment that results in a loss of your personal data.
