A little about privacy.

This preview has no accounts, advertising scripts, or third-party analytics. Your puzzle progress and keyboard preference are stored in this browser. Clear site storage to remove it.

Personal progress counts, shelf filters and next-puzzle suggestions use those saved puzzles. They describe this browser’s current collection, not account history, other players or a leaderboard. No additional identifier or server-side profile is created for these features.

Preview content

The original puzzles were drafted and checked with AI assistance and have not been reviewed by an independent English puzzle editor. They remain labeled as drafts. This development preview is marked noindex and cannot be built in public mode until the listed content passes the editorial release gate.

Sharing

Share links contain the puzzle identifier, campaign tags, and optionally your solve time and whether you used help. They contain no player name or filled answers. Sharing opens only after you choose to share; you decide where it goes.

Usage events

The interface emits local browser events for starts, completions, sharing, challenge arrivals, and printing. This preview does not transmit those events to an analytics service. Hosting providers may keep ordinary request logs.
