Skill checkmarks and quiz results are stored in this browser’s localStorage. We do not request names, email, age, health information or an account. Checkmarks are not sent to our server or synced between devices. Clearing browser data removes progress.

Videos open only when you follow an external link; no YouTube player loads automatically. External sites have their own privacy terms. Typography may load from Google Fonts; the hosting provider processes technical requests needed to display the site. We load Google Tag Manager (GTM-TP2TRN26), which may load tags configured by the owner. Loading sends a technical request to Google. Actual analytics and advertising processing depends on published tags and consent settings; it is not established by this site’s code alone.
