Blackbook Pro is a one-time purchase — not a recurring subscription. We do not set up UPI AutoPay, e-mandates or card mandates, and nothing renews automatically. There is no recurring payment to cancel.
When your Pro period (30 or 365 days) ends, your account simply returns to the free plan — you keep your account, progress and saved words. Extend any time from the pricing page; new days add on top of remaining validity.
Charged twice by mistake, or paid but Pro not active? See our Refund Policy or contact us with your payment ID.
