Privacy & kids' safetyPrivacidad y seguridad de los niños

The short version: nothing is collected from kids. Ever.

• We collect nothing from children.

  Kids can watch every video and use every page without giving us any information.

• No accounts, no ads, no tracking.

  There are no sign-ups, no advertising, no analytics and no tracking cookies. We don't store anything in your browser.

• No chat or comments.

  There is nowhere on this site for anyone to post or send messages.

• Videos play from this site.

  The lesson videos are not hosted on YouTube or another video service.

• Our web host.

  The site is hosted on Cloudflare Pages. Like any web host, Cloudflare handles basic technical details (such as an IP address) to deliver the pages and keep the site safe. We don't use that to identify anyone.

• Buying the books.

  Purchases happen on Amazon, not here. Amazon's own privacy policy applies there.

• If a grown-up emails us.

  We use your email only to reply to you, and we don't add you to any list.

• Practice app (later).

  If we add a practice app, progress and stars will stay on your own device, with no accounts.
