Settings and progress in this browser

The app stores dimensions, mode, grid and center preferences, completed cells and the current row in local browser storage. Each blueprint has its own progress record. The tool has no progress-sync service and does not upload these storage records. Optional analytics may capture visible page interactions as described below.

Choose Clear progress to clear the current blueprint. To remove all settings and progress for this site, use your browser’s site-data controls. Clearing site data or using a browser that cannot save storage can prevent you from resuming a build.

Links and downloads

A shared link contains the width and height, or circle diameter, and the mode. It contains no completed cells or current row. Anyone opening it sees the same geometry and their own browser’s progress, if any.

PNG generation happens in your browser. The image is a clean reference without your completion marks.

Optional analytics and your choice

On the production site, choose Allow to enable Google Analytics 4 and Microsoft Clarity. Google Analytics measures visits and interactions in aggregate reports. Clarity measures interactions through heatmaps and may record sessions showing page content, clicks, scrolling and other activity. These providers can process page URLs, browser/device information and identifiers and use cookies; we do not promise that this collection is anonymous or cookie-free.

Before you allow analytics, or after you decline, neither provider’s script is loaded. Advertising consent remains denied. Your Allow or Decline choice is saved in localStorage, separately from tool settings and blueprint progress. If browser storage is unavailable, the choice may last only for the current page.

Use Analytics settings in the footer to change your choice. Choosing Decline after allowing analytics sends withdrawal signals, removes this site’s Google Analytics and Clarity cookies, and reloads the page to stop the scripts. It preserves your tool settings and blueprint progress. Withdrawal does not erase information already received by the providers, and this site cannot remove cookies on their own domains.

Accounts and hosting

This app has no accounts or advertising scripts. It is hosted by Cloudflare Workers, which may process request information such as URLs, IP addresses and browser information according to its service configuration and privacy policy. Analytics choices do not control hosting request logs.
