Every "anonymous" Secret Santa app lets the organizer peek at assignments. Sotto doesn't. Server-side draws, PIN-gated reveals, sealed envelopes that burn 10 seconds after opening. No accounts. No emails. No tracking. Even we can't see who got whom — the architecture makes it impossible. Free forever. Built for crews who want real anonymity, not promises. Coming next: Secret Cupid, Secret Diwali, Secret Feedback. Sotto is a platform for anonymous group games. The secret stays secret.
