*Important Subscription, Pricing and Offer Details
 

  • Details: Subscription contracts begin when the transaction is complete and are subject to our Terms of Sale and License & Services Agreement. For trials, a payment method is required at sign-up and will be charged at the end of the trial period, unless cancelled first. 
  • Renewal: Subscriptions automatically renew unless the renewal is cancelled before billing. Renewal payments are billed annually (up to 35 days before renewal) or monthly (up to 5 days before renewal) depending on your billing cycle. Annual subscribers will receive an email with the renewal price beforehand. Renewal prices may be higher than the initial price and are subject to change. You can cancel the renewal  as described here in your account or by contacting us here.
  • Cancellation & Refund: you can cancel your contracts and get a full refund within 14 days of initial purchase for monthly subscriptions, and within 60 days of payments for annual subscriptions. For annual renewal payments (including post-trial payment), you can get a pro-rated refund of the remaining months left in your term. For details, visit our Cancellation & Refund Policy.
