Common questions
How do I manage or cancel my subscription?
Apple handles Knock subscriptions. On your iPhone, open Settings, tap your name, and then tap Subscriptions. Choose Knock to change or cancel your plan. Cancelling stops the next renewal, and you keep access until the end of the current period.
How do I restore my subscription on a new device?
Sign in with the same Apple ID, open Knock, and tap Restore Purchases in the settings menu.
How do I request a refund?
Apple processes refunds for App Store purchases. Visit reportaproblem.apple.com and sign in with your Apple ID.
What happens if I lose my connection during a match?
A computer player covers your seat while you are away. Open Knock again and it rejoins the same room, and you take your seat back at the start of the next trick. A player who is still away when the match ends receives a rating penalty in ranked play.
What happens if the host leaves?
Another player takes over as host automatically. The current hand is dealt again, and the match continues with every score kept.
How do I delete my account?
Open Knock, go to the settings menu, and tap Delete Account. This permanently removes your account, your rating, and your match history. You can also email us to ask for deletion.
