Part of the content on this website is produced with the help of artificial intelligence. The guided course, the reading library and the reference material are written and checked by the operator; word lookups are model-produced and then cross-checked against curated linguistic databases before they are shown; texts and dialogs a user generates for themselves are unchecked model output. Details are in section 9 of the privacy policy. In every case the content may contain errors, inaccuracies or outdated information. We do not guarantee its correctness, completeness or reliability. Use it as a learning aid, not as an authoritative reference.
This site links to a small number of external pages (for example Google's privacy policy in our own privacy policy). We have no influence over the content of those pages and accept no liability for them; their own terms and privacy policies apply. See our privacy policy for what leaves the app and to whom.
