Rejoice
Join-by-QR participation app with a live, privacy-preserving dashboard
Release candidate
People join a community challenge by scanning a QR code, without giving a name or email, and log a daily check-in on a private calendar. A projector page shows live totals, and group figures are hidden until a group is large enough to stay anonymous.
What is built
- Anonymous sign-up in under a minute, protected by a CAPTCHA
- Realtime aggregate counters for a live display
- Small-group suppression so no individual can be identified
- Row-level security throughout; load-tested for hundreds of sign-ups in minutes
How it can serve an agency
Public-health and civic campaigns, event check-in and volunteer pledges where an agency wants live participation numbers without collecting personal information.
