Common questions
Do I need an account?
No. Building books, importing, scanning games and training all work signed out, and your data stays on your phone. An account is only needed for Premium features like cloud backup and sharing.
How do I import my games?
Open More → Game sites and enter your Lichess or Chess.com username. Chess Second downloads your public games and compares them with your books. You can also paste a PGN.
What does "left the book" mean?
It's the first move in a game that isn't in your repertoire, either your own move or a reply your book doesn't cover yet. Those positions go to your Misses list so you can add them to the book or train them.
How do I move my books to a new phone?
With Premium, back up each book to the cloud, then sign in on the new phone and restore. Without Premium, export each book as PGN and import it on the new phone.
How do I cancel or manage my subscription?
Subscriptions are handled by the store you bought from. On iPhone, go to App Store subscriptions. On Android, go to Google Play subscriptions. Deleting the app or your account doesn't cancel it.
I bought Premium but it isn't unlocked.
Make sure you're signed in to the same Chess Second account, then open the Premium screen and tap Restore purchases. If that doesn't work, email us with the date of the purchase.
How do I delete my account?
In the app, go to More, tap your account and choose Delete account. You can also email us from the address on the account. See the Privacy Policy for what gets removed.
