• Cube states. Every solver runs as JavaScript in your own browser, in a Web Worker. Pressing Solve makes no network request. There is no cube-state endpoint on any server because there is no server-side solver.
• Timer results. Your solves are kept in your browser’s localStorageunder a single key. They are not uploaded, not backed up and not readable by this site’s operators. Clearing site data deletes them.
• Scrambles. Generated locally by the same engine.

Anonymous page analytics. This site uses Vercel Analytics to count page views. It records the page visited, referrer, and coarse device and country information. It does not use cookies, does not build a profile across sites, and does not identify you.

Advertising, if it is switched on. Ad slots are wired but render nothing unless an AdSense publisher id is configured. If ads are enabled in future, Google may set cookies to serve and measure them, governed by Google’s advertising policies. This notice will be updated at that point, and there will still be no cube data involved.

Cube Solver Hub sets no cookies of its own. Your light or dark theme preference is kept in localStorage, not a cookie, and is never sent to a server.

The site collects no personal information from anyone, of any age. There is nothing to sign up for and no field that asks for anything about you.

If this policy changes materially — most plausibly because advertising is switched on — this page will be updated. The commitment that cube states stay on your device is structural, not a policy choice: there is no code anywhere that could send them.

More on how the solvers work is on the about page.
