Terms of Use
The service gives a student a private teacher available at any hour. These terms are deliberately short: they say what we undertake to provide and what we ask of you.

What the service is
A platform for learning with a computer teacher, following an ordered curriculum. A lesson runs in writing and in speech, and at the end you can take a worksheet and submit it to be marked.
Every account gets a free allowance of learning time. When it runs out you can still read what you have covered, and to carry on learning the account has to be extended. As these lines are written there is no payment provider connected, and the screen says so plainly rather than pretending to take a card.
The teacher is software
The teacher is not a person. It is software that produces explanations, and it can be wrong — including when it sounds certain. Do not rely on it as the only source for an exam answer, and check anything that looks odd against your teacher at school or against the book.
The service is not a substitute for school and does not award a certificate, an official grade, or any entitlement.
Your account
An account belongs to one person. Do not share a password, and if you think somebody else has been in your account, change it and tell us.
An account for a minor is opened under the responsibility of a parent or guardian, who may look at it, ask for corrections, and close it at any time.
Fair use
The service is for learning. Do not use it to harass anyone, to spread offensive material, to try to extract things from the system that have nothing to do with learning, or to load it automatically.
We may suspend an account that does those things. We will only do so with a reason, and we will say what it was.
Content
The teaching content on the site is ours. You may learn from it, print a worksheet and use it in a classroom. You may not copy it at scale onto another site.
What you write in a lesson remains yours. We use it only to run the service for you, as described in the privacy notice.
Changes and ending
You can close an account at any time, and closing it deletes what was stored in it. We may change the service and these terms; a material change will be shown inside the product.
The service is provided as it is. We work to keep it running and correct, but we cannot undertake that it will be free of faults or mistakes.
