Game storage and site analytics
Your progress stays in this browser.
We use local storage for your puzzle entries, notes, elapsed time, and hint count. That data is not sent to an account or cloud service. Clearing site data removes saved progress.
Shared links contain a puzzle, not your progress.
A share link contains the original puzzle clues in its URL fragment. It does not include your entries, time, or personal information. Anyone with the link can open that original puzzle.
Site analytics
With your permission, we use Google Analytics and Naver Analytics to measure visits and site usage. These services may receive browser, device, and usage information and may use cookies or similar technologies. Puzzle entries and candidate notes are not intentionally included in analytics events.
Advertising and Google cookies
We may use Google AdSense to support the service. Google and other third-party vendors may use cookies to serve ads based on visits to this site or other sites. Google advertising cookies allow Google and its partners to provide personalized ads when you have consented, or non-personalized and limited ads where appropriate.
Your privacy choices
Non-essential analytics and advertising storage are denied by default until you choose otherwise. You can accept, reject, or change these choices at any time through Cookie settings in the footer. Essential browser storage used to save a puzzle is separate and remains available so the game can work.
