YOUR TIME, YOUR SPACE

A small privacy note.

Updated September 28, 2026.

Local game progress.

The practice game stores your current pattern, moves and completed patterns in your browser’s local storage. This data stays on your device and is not sent to our server. Clearing this site’s browser data removes it. If storage is unavailable, the game can still run for the current session.

YouTube videos.

Guide pages initially display a thumbnail hosted on assets.yarnation.org. A YouTube privacy-enhanced iframe loads only after you click play. YouTube then receives connection information and may apply its own data practices. You can choose the direct YouTube link instead. See Google’s privacy policy.

Hosting.

Cloudflare delivers this site and its images. It receives normal connection data such as IP address, browser information, request time and requested URL to serve and protect the website. See Cloudflare’s privacy policy.

No account needed.

This version has no account system, payment form, advertising scripts or analytics tags. We do not ask for personal details to play or browse. External links follow the destination site’s privacy practices.
