This site is free and always will be. It has no ads, no accounts, no tracking and no links to outside services. Progress is saved only in this browser, and clearing the browser's data removes it.

Profiles for each child

Children can each have a profile under My learning. A profile is only a nickname and a picture, kept on this device. There are no passwords, so anyone using this browser can open any profile, and progress does not move between devices. Please use a nickname, not a full name.

Spotted a mistake?

Every lesson should be accurate and safe, so please tell me if something looks wrong. Email [email protected] and say which lesson and level it was. This opens your own email app, and the site itself collects nothing. Please don't include details about a child.

Privacy

This site has no accounts, cookies, ads or analytics, and it does not collect information about you or your child.

• Saved on this device only: each child's nickname, picture, level, stars and learning history. You can remove a child under My learning, or clear this browser's data to remove everything.
• Hosting: the site runs on Cloudflare Pages. As with almost any website, the host may keep basic technical logs, such as IP addresses, to run the service and keep it secure. This site does not receive or use those logs.
• Read-aloud: this uses voices already on your device, so lesson text is not sent anywhere.
• If you email: your message and email address reach the feedback inbox. They are used only to reply and to fix the problem. Your email provider handles the message too.
