Before you write
How do I install the Android app?
Open the download page on your Android phone and follow the three steps. You may need to allow installs from your browser for this one file.
Can I use the site offline?
Once you have visited the site, most pages are cached by your browser and the lessons keep working. AI Practice needs a connection.
How do I report a wrong translation?
Choose “Lesson or phrase correction”, paste the phrase, and tell us what you would say in your region. We review corrections in batches.
How do I delete my AI Practice data?
The site stores a random device ID in your browser and the server keeps only a daily counter. Clear site data in your browser settings to remove the local ID. See the privacy policy.
