Privacy and analytics

The games and developer tools run in your browser. No account, application backend, or server-side example database is used.

Browser-local example data

Game preferences, records, high scores, reaction attempts, and best rounds are stored in your browser using local storage. The contrast checker, shadow builder, and gradient builder can place validated settings in the page URL so those configurations are shareable. JSON input and output, regex patterns, regex test text, matches, captures, and HTTP explorer searches stay in memory only and are not added to URLs or local storage. The HTTP explorer uses static reference data and does not check URLs or make network requests.

Optional analytics

Google Analytics is loaded only after you select "Allow analytics." When enabled, it measures page visits and product actions such as viewing a prompt, copying a prompt, launching an example, or using a fixed tool action. Event properties contain identifiers, categories, and fixed action names; they do not contain prompt text, game progress, colors, generated CSS, JSON documents, regex patterns, test text, matches, captures, or other information you type.

If you decline, the Google Analytics script is not loaded by this site. Your choice is stored in local storage so the site can remember it.

Change your choice

Resetting the choice removes the saved analytics preference and asks again on the next page load. It does not clear game progress or change the current tool.
