Terms of use
These terms are short because the site is simple: the courses are free, and we ask you to use them fairly.
Last updated: 24 September 2026
Using the site
- You can use all courses, exercises and reference pages for free, for personal learning and in teaching.
- You may link to any page. Please don't copy whole chapters or tables onto other websites.
- Don't try to disrupt the site, for example by sending automated requests in bulk.
Your account
- An account is optional. You can create one with Google or with an email address that belongs to you.
- You can delete your account at any time on your account page.
- We may close accounts that are used to abuse the site.
No guarantee
We work hard to make the courses accurate, but we can't guarantee that they are free of mistakes, or that the site will always be available. The courses are a learning aid, not a certified qualification: the A1–B2 levels describe what a chapter teaches, not an official exam result.
The site is provided free of charge and “as is”. As far as the law allows, we are not liable for any loss caused by using it. Nothing in these terms limits rights you have under the consumer law of your country.
Changes
If these terms change, the new version will be published here with a new date.
