This Privacy Policy applies to information that we, MARGARITIDIS AUDIO VISUAL (“MARGARITIDIS”, “we”) may collect about you in connection with your access and use of:

  1. MARGARITIDIS website located at (the “Website”);
  2. MARGARITIDIS cloud-based Event Management Platform named BlueTree at (the “Platform”);
  3. our social media pages;
  4. any other products and services offered by MARGARITIDIS (collectively, “Services”).

This policy applies to the following classification of individuals (data subjects) that interact with MARGARITIDIS:

  • Customers: Individuals that are employees or associates of our direct customers (hosts or organizers of events) and are authorized to access and use our Platform pursuant to a relevant agreement between the customer and us.
  • Event Attendees: Individuals who are invited to, register for or check into an event organized by a customer through our Platform.

Usually, this information includes name, job title, company name, email address, mailing address, phone number, browser and device information (including IP Address), profession, medical specialty and in some cases the time of joining and the time of leaving an event.

Furthermore, we take videos and photos of the events both on behalf of our customers and for our own purposes.

Your personal information may be given to us by you, or by a customer or customer administrator on your behalf.

If you are submitting Personal Data relating to any other person (including as a customer administrator, or on behalf of other individuals at your company), you represent that you have full authorization to provide this information to us, and to permit us to use it in compliance with this Privacy Policy.

We encourage events attendees to review the customers’ privacy policies to further understand the types of data collected.
