Privacy-Respecting Festival Check-In and Digital Passports

Design loyalty features that reward participation without making precise location public.

Collect only what the feature needs. A festival stamp can be confirmed with a rotating code, ticket validation or staff scan without storing continuous location history. Default achievements to private, let users select what to share and explain retention periods. Prize drawings require separate eligibility terms. Children need heightened privacy protections and appropriate consent. Security reviews should cover QR replay, account takeover and unintended disclosure.
