stripeFor purchases of credits on playstockfish.com
Credits are non-refundable, and they never expire. Once bought they stay on your account until you spend them, however long that takes.
A credit is site credit for the paid features on playstockfish.com, such as coaching, game analysis and the other tools that use AI. It is not money, has no cash value, and cannot be exchanged for cash.
Credits are sold as digital content that is available immediately, so a purchase is final and is not refundable, whether the credits have been spent or not. If a purchase was charged in error - a double charge, or credits that never arrived - contact us and we will put it right.
Credits do not expire. They stay on your account for as long as the account exists, and they are not reduced by leaving them unused. Deleting your account gives up any credits still on it.
Credits belong to the account that bought them. They cannot be transferred, sold or shared between accounts, and they cannot be reinstated on a new account.
Prices, pack sizes and what each feature costs in credits can change. A change never takes credits off an account you have already paid for - a balance bought at one price stays yours in full.
Payments are taken by Stripe. Card details go straight to Stripe and are never held by this site. Your card statement shows the charge under our Stripe account name.
If a payment has been taken and the credits have not arrived, or anything else about an order looks wrong, use the contact page and we will sort it out.
