Privacy & local data

Your tool data stays local

Puzzle seeds, board arrangements, levels and move counts are saved locally by mode. Undo history remains in the current session. No player account or cross-device save service is used.

Guides and theme

Saved-guide bookmarks and the theme preference are kept in separate local storage entries. They are tied to this browser and origin. Private browsing, storage restrictions or clearing site data can remove them.

Usage analytics

Production pages use Google Analytics 4 under the Playgames property. Events measure page views and bounded tool actions such as start, completion or copy, using the product identifier, allowlisted categories and numeric counts. We do not send typed names, board titles, tile labels, uploaded image data or file names as custom event parameters. Analytics page URLs omit queries and fragments and referrers are reduced to their origin. Google may process technical and network information under its own policies.

Advertising in guides

Only the six original guide detail pages can show one Google AdSense display advertisement after the article. The practice, daily and challenge game pages do not load advertising code. Ads are labelled Advertisement, occupy reserved space and do not cover puzzle controls. We request non-personalized ads; Google and its partners may still use cookies or local storage for frequency capping, measurement and fraud prevention and process technical or network information. The links below explain Google’s advertising and partner-site data policies.

Advertising choices

Advertising is enabled only on the production host after Google’s certified Privacy & Messaging platform determines that the applicable consent is ready. Where European consent applies, refusing storage or Google vendor consent prevents an ad request. Use Advertising privacy settings in a guide footer or on this page to reopen the Google consent message when it applies. Do Not Track or Global Privacy Control suppresses both the advertising loader and its consent platform. If consent, the advertising service or a privacy extension blocks an ad, the guide remains readable and the reserved space stays empty.

Your browser choices

The Google loader is not loaded when the browser reports Do Not Track as 1. Privacy extensions may also block analytics. You can clear product storage in your browser’s site-data settings; this also removes the locally saved puzzle arrangement and move count.

Copying a challenge

Clipboard actions copy result text and a starting puzzle link only after you activate the control. The page does not send a message or post to a social account. A copied link does not transfer your saved board.
