Event photographs, found by the people in them
An organiser uploads the photographs from an event. Each guest enters the event's code, takes one selfie, and is shown the photographs they appear in — and only those.
You need the code for your event, and it comes from whoever organised it: printed on a card, shown on a screen, or sent to you. There is nothing to sign up for and no account to make.
Your selfie is never stored. It is held in memory, used for that one search, and discarded with the response — never written to disk, never added to the searchable photographs.
Organisers upload and manage their photographs in the operator panel. Accounts are created by us rather than signed up for; write to the address on the support page.
