The monthly price is shown before purchase and may vary by region. Payment is charged to your App Store account. The subscription renews automatically unless cancelled in App Store settings at least 24 hours before the end of the current period. Cancelling stops renewal while keeping access through the verified paid end date. A verified billing grace period keeps access through its end. If a payment cannot be collected without grace, or the subscription expires or is revoked, access ends. A refund record alone changes access only if Apple also ends or revokes the subscription. Restore purchases with the same Sudoku Coach account and wait for server verification, then manage the subscription from Account inside the app. Deleting the Sudoku Coach account does not cancel App Store billing.
