Hosting and visit statistics

Cloudflare hosts these pages and may process request data, including IP addresses, under its privacy policy. Cloudflare Web Analytics, when enabled, measures aggregate visits and performance without analytics cookies. Testing can be included in counts; page views are not unique people.

Game tools and saved progress

The Block Blast board planner runs locally in your browser. Board inputs and pieces are not uploaded to a solver or AI service. It saves your latest position in localStorage. Color Block Jam checklists also save progress on this device. You can remove saved state through your browser’s site-data controls.

Board-sharing links include the puzzle in the URL fragment after #. Anyone receiving the link can reconstruct it. Fragments are not sent in ordinary HTTP requests. Saved browser data on a former game subdomain does not automatically transfer to this main site.

Videos, comments and feedback

YouTube players load only when you choose to play a video. Color Block Jam comments load from Giscus/GitHub only when requested; posting requires a GitHub account and is public. Footer feedback links also open a public GitHub issue. Do not include private information.

Advertising

These pages currently load no advertising scripts. An ads.txt entry identifies the publisher account; it does not establish approval or income. This notice will be updated before advertising changes the way visitor data is processed.
