Privacy and face matching
Do guests' selfies go into a public database?
The short answer
No. A matching selfie is used only to match photos at the event it belongs to, and it does not go into a public face database.
The selfie is tied to the event and to the guest's personal gallery. It is not shown to other guests, not published, and not used for advertising or sold.
Full details on how personal information is handled, how to request access, correction, or deletion, and the limits on those requests are in the privacy policy.
