By purchasing a quarterly subscription, you acknowledge that your subscription has an initial and recurring payment feature and you accept responsibility for all recurring charges prior to cancellation. Your subscription will be automatically extended for successive quarterly periods, at the then-current subscription rate. To cancel your subscription at any time, you must email us at firstname.lastname@example.org. If you cancel, you may use your subscription until the end of your then-current subscription term. Tagstand may submit periodic charges (e.g., quarterly) without further authorization from you, until you provide prior notice that you have terminated this authorization or wish to change your payment method. Such notice will not affect charges submitted before Tagstand reasonably could act.
