Personal Data You Collect
When people buy tickets, RSVP, book, follow or sign up for emails through your profile or events, you are the controller of the personal data they give you, and Event Schedule processes it on your behalf: only to provide the service to you, and as described in the Privacy Policy.
You are responsible for having a lawful basis for collecting that data and for every message you send, including permission to email any contacts you import, and for answering your attendees' requests about their data. Event Schedule will help you do so.
If you buy a Boost, you authorize Event Schedule to measure the campaign by telling Meta about ticket purchases on the boosted event, for buyers who allowed marketing cookies.
