For details regarding publication of data please note in particular clause 4.1.1 (access to raw data and associated metadata), and clause 5.3.1 (access to results) of this policy. For details regarding the collection and processing of personal data in connection with UPEX the UPEX Privacy Policy applies. For details regarding the collection and processing of personal data in connection with the use of the European XFEL Facility the data handling provisions of the Terms and Conditions for the non-proprietary user access to the European XFEL Facility (currently in preparation) apply.
Unless otherwise stated in the Scientific Data Policy, the scientific data will be stored as described in the Data retention policy.

I consent to the processing of my personal data (first and last name, name and address of the institute I am currently working for, gender, birth date, birth place including country, nationality) by the European XFEL GmbH for the purpose of matching these with embargo lists.
