How totals work
The Day view ranks each device’s best validated score for that UTC date. Month and All-time add those daily best scores and report the number of distinct challenge days played. There are no seeded or invented rows.
Public rankings
Daily challenge leaderboard.
Only completed daily challenges that a player explicitly chooses to publish appear here. Scores are recalculated by the server from the submitted five brackets; standard games are never eligible.

Pseudonymous by design
The browser creates a random device ID only when needed. The API stores only a salted SHA-256 hash of that ID, along with the chosen nickname and validated score summary. Publishing is optional, and this device can request deletion of all linked public scores.
