Egg hunt leaderboard
The hunt is blind both ways: you can't see the unfound eggs, and the server can't see you. This is the server's half. Every score is computed on encrypted data: it holds no key and never sees a location, a score, or which egg anyone found. Below is the real traffic it handles: encrypted queries arriving, getting computed on, and leaving, all as polytext.
📍 location + time → 256 bits → encrypted on phone → upload
this all happens on your phone; only the polytext is ever sent
