Terms of use

DayOneCode is free to use for learning. These are the few rules that come with it, in plain words.

Using DayOneCode

• You may use the lessons for yourself, with your family and in your classroom, for free.
• Please do not copy the lessons, the characters or the recordings onto another website or app.
• Do not try to break, overload or misuse the site.

Children

The lessons are made to be safe for children. A parent, guardian or teacher should decide whether a child uses the site, and stay nearby for the first lessons. There are no accounts and no chat.

The practice computer and real computers

Lessons run on a pretend computer in your browser. Later lessons explain how to try commands on a real computer; when you do, follow the lesson's safety notes, practise inside a practice folder, and ask a grown-up before installing anything. You are responsible for what you run on your own computer.

No promises beyond the lessons

We work hard to keep the lessons correct and the site running, but DayOneCode is provided as it is, without guarantees. A sticker or certificate shows that a level was finished in this browser; it is not a qualification.
