Dear BioBrillouin 2025 Organizers, My name is Sonia Montanari, and I'm the Marketing Manager for CrestOptics. I currently handle all our events organization and related matters. CrestOptics will be in attendance at the 9th International BioBrillouin Conference, held on 25–27 November 2025 in Berlin, Germany. Could you please clarify a couple of points regarding the attendee list and data sharing compliance? - Attendee List Sharing: *Will an attendee list be shared with sponsors, such as CrestOptics, for commercial follow-up? If so, what contact details (e.g., email address, title, affiliation) will be included?* - GDPR Compliance: *We need to confirm that this sharing is GDPR compliant. Could you please confirm that attendees provided the necessary, explicit consent for their data to be used by sponsors for direct commercial contact?* - Privacy Policy Language: *For our records, please share the specific language from your registration's privacy policy that covers data sharing with third-party sponsors for marketing purposes at your earliest convenience.* Thank you so much for all your hard work on the event! We are very excited to be part of it. Best regards, Sonia Montanari, Ph.D. Trade Marketing Manager *Mobile*+39 333 2044093 *Website*www.crestoptics.com <https://crestoptics.com/> *Address*Via di Torre Rossa 66, 00165 Rome, Italy <https://crestoptics.com/> CONFIDENTIALITY AND PRIVACY NOTICE: The information in this email is confidential and protected by civil and criminal law.
