The workbook contains no advertising and does not require a child account. An adult should manage downloads, future purchases and contact with support. Please do not send children's names, photographs, recordings, learning records or other sensitive information. Learning progress stays on the device. For the website operator and personal-data requests, see our Legal information and Privacy pages.

The downloadable Windows edition requires Windows 10 or 11, 64-bit. Extract the entire archive, then follow START_HERE.html and use the included launcher. Keep the launcher open during the lesson. The website can be browsed on phones and tablets, but this does not make the Windows program an Android or iOS application. For help, send the product version, Windows version, exact error and the steps that led to it. A screenshot may help after removing personal information. Do not send passwords, payment-card details, activation codes or children's data.
