Private Events.
Public Fun.
Organize and attend encrypted events using your Hat identity. Anonymous RSVPs, secure check-in, and zero personal data exposed — ever.
Browse & Organize
Discover nearby events or create your own. Everything runs through your Hat identity — your real name and contact info stay private.
Events, Reimagined for Privacy
Every event detail is encrypted. Attendees are anonymous. Organizers stay in control without collecting personal data.
Encrypted Event Details
Event name, location, description, and time are end-to-end encrypted. Only confirmed attendees and the organizer can see the full details.
ENCRYPTEDAnonymous RSVP
Attendees RSVP using their Hat identity. The organizer sees Hat codes and status — never real names, emails, or phone numbers.
PRIVACYSecure QR Check-In
Arrive at the event and check in with a one-time QR code tied to your Hat. No scanning of IDs, no sign-in sheets, no data collection.
SECUREFull Organizer Tools
