Your lifetime court pass
One payment, no subscription
The standard offer is US$37 once. CALLEN saves 25%, bringing the offer to US$27.75. Stripe shows your final total and any applicable charges before you confirm payment.
What you receive
Access to all 12 practice themes, unlimited Daily Rallies, spaced reviews and future DinkTank game updates while the service operates. There is no recurring membership fee. Access belongs to your account and works on devices where you sign in.
Rally Lab, placement, your first Daily Rally and Attack or Not practice are free. Payment is not required for those features. Court IQ is a training estimate and does not guarantee a playing rating or match results.
30-day money-back guarantee
Try DinkTank for 30 days from your purchase date. If it is not for you, request a refund within those 30 days through our billing support. We will refund the full amount you actually paid, including purchases made with a discount, to your original payment method. We do not deduct payment processing fees.
There are no usage restrictions and you do not need to prove improvement or give a reason. Your paid access ends when the purchase is refunded; you can continue using the free features. This guarantee does not limit any applicable consumer rights, including rights that may apply after the 30-day window.
Access and recovery
Keep access to your purchase email. If your payment succeeds but access is missing, restore the purchase from your account rather than paying again. A full refund or a disputed payment can suspend the related paid access.
Purchase help
Billing support and purchase recovery. Any applicable consumer rights remain unaffected.
