Your opening book, on every device.
Signed in, the opening trainer keeps your book on your account now: learn a line on the bus, and it’s due on your laptop too. Only you see it, and nothing about it is shown to anyone else.

The short version
- Your book saves to your account and follows you between phone and laptop
- It works offline, and catches up when you’re back
- A book you kept before signing in is offered once, by name, and never overwrites the one you have
- Only you see it, and Clear my book clears it everywhere
Until now the opening trainer kept your book in one browser. Learn the Italian on your phone and your laptop had never heard of it. Sign in and that’s over: your book lives on your account, so the lines due before club night are due wherever you open the trainer.
Every line you finish is filed on your device straight away, so a dead spot on the bus doesn’t stop you. It reaches your account as soon as you’re back online, and your other devices catch up by themselves. Your club night, new lines a day and board come along too.
Already have a book?
If this browser has a book from before you signed in, the trainer asks once, and names it: how many lines, which openings. Save it and it joins your account; where both have the same line, the one you ran most recently is kept, and no line already on your account goes missing. Not yours? Say so and it stays where it is.
It’s still private practice. Your book and its XP are seen by you alone, never on your profile or your Club card, and XP never turns into crowns. “Clear my book” clears it from your account and from every device’s copy of it, and a line still waiting on your other phone can’t sneak it back. A book someone else keeps in the same browser is theirs, and stays put. Saving needs an account: guests and anyone signed out keep their book in their browser, as before. The privacy page lists exactly what’s kept.
