This Return Policy applies to purchases made on the Platform (https://bobbycarlsen.com), owned by Sigmoid Vedanta Technologies.

Digital services

Sigmoid Technologies sells digital services only (subscriptions to Kuikma Chess Pro, delivered online to your account). No physical products are sold or shipped, so there are no items to return, exchange or send back, and no packaging or quality-check requirements apply.

Refund in place of return

We offer a refund within the first 7 days from the date of your purchase, as set out in our Refund Policy. If 7 days have passed since your purchase, you will not be offered a refund of any kind, except where required by law.

Defective or non-working service

If the service does not work as described (for example Pro features are not available on your account after payment), please report it to our customer service within 7 days of purchase. We will fix the problem or, if we cannot, refund your payment in full.

How to request

Contact us with your registered email address and the payment / transaction reference: email sigmoidvedantatechnologies@gmail.com or phone +91 74060 53777. Once your request is approved, we will notify you by email, and the refund will be processed within 7 days to the original payment method.
