Cognidyne is advertised with a 60-day money-back guarantee from the date of purchase, with the brand asking that you use it for at least 30 days before requesting a refund. We recommend confirming the exact current terms directly at checkout before ordering.
Contact Cognidyne's official customer support directly — not this website — with your order details, within the guarantee window confirmed at your time of purchase.
Calendar your deadline the day your order arrives. This is the single most practical thing you can do to protect your guarantee.
