Effective 7 October 2026
Cancel any time. Cancel a subscription from your account (Manage billing or cancel) or by emailing [email protected]. Cancellation takes effect at the end of the current monthly billing period: you keep access until then and are not charged again.
First payment. If you are not satisfied with a new subscription to a vertical, email [email protected] within 7 days of your first payment for that vertical and it will be refunded in full and the subscription cancelled. This applies once per subscriber per vertical.
Renewals. Monthly renewal payments are not refunded, in whole or in part, once the billing period has begun, except as set out below.
Errors. Duplicate charges, charges after a confirmed cancellation, and other billing errors are refunded in full.
Discontinued verticals. If Kastra Research stops publishing a vertical, the subscription is cancelled and the unused part of the current period refunded.
Refunds are returned to the original payment method through Stripe and usually appear within 5 to 10 business days, depending on the card issuer. There is no physical delivery: access to subscriber editions is online and begins as soon as payment completes.
