Cookies & local storage
A small amount of storage, with a clear purpose
Game storage
Saved puzzles use browser local storage so that you can continue after refreshing or returning to the page. This is separate from the cookies that analytics services may use.
Your choices
You can accept or reject optional analytics and advertising technologies, and reopen Cookie settings from the footer at any time. You can also clear site storage in your browser settings. Doing so deletes saved games. If browser storage is unavailable, you can still play, but progress cannot be kept between visits.
Analytics services
Google Analytics and Naver Analytics are loaded only after analytics consent. If you reject analytics, these measurement scripts are not loaded. Changing your choice stops future optional measurement on this browser; you may also clear existing cookies through your browser settings.
Advertising services
Advertising partners, including Google, may use cookies or similar technologies for ad delivery, fraud prevention, frequency control, and—when you agree—personalization. Advertising consent is separate from analytics consent and can be changed in Cookie settings.
