a. Billing

By starting your Teeneinstein membership, you are expressly agreeing that we are authorized to charge you the membership fee associated with the type of membership (monthly or yearly) you chose during registration. You agree that we are authorized to charge you the membership fee at the then-current rate to the Payment Method you provided during registration (or to a different Payment Method if you change your account information). Please note that prices and charges are subject to change with notice. As used in these Terms of Service, "billing" shall indicate either a charge or debit, as applicable, against your Payment Method. The membership fee will be billed at the beginning of the paying portion of your membership and each month or year thereafter unless and until you cancel your membership. Sign in to your Teeneinstein parent account, go to the Membership tab, and click Manage your account to see the commencement date for your next renewal period. We automatically bill your Payment Method each month or year on the calendar day corresponding to the commencement of your paying membership. Membership charges are fully earned upon payment.

Note: In the event your monthly membership began on a day not contained in a given month, we bill your Payment Method on the last day of such month. For example, if you became a paying member on January 31, your Payment Method would next be billed on February 28.

You acknowledge that the amount billed each billing period may vary for reasons that include differing amounts due to changes in your membership plan, and you authorize us to charge your Payment Method for such varying amounts. Payments are nonrefundable and there are no refunds or credits for partially used periods. We may change the fees and charges in effect, or add new fees and charges from time to time, but we will give you advance notice of these changes by e-mail. If you want to use a different Payment Method or if there is a change in Payment Method, such as your credit card validity or expiration date, you may edit your Payment Method information from your Account management page. To access your Account management page sign in to your Teeneinstein parent account, go to the Membership tab, and click Manage your account. If your Payment Method reaches its expiration date and you do not edit your Payment Method information or cancel your account (see, "Cancellation" below), you authorize us to continue billing that Payment Method and you remain responsible for any uncollected amounts.

b. Ongoing Membership

Your Teeneinstein membership will continue in effect unless and until you cancel your membership or we terminate it. You must cancel your membership before it renews each billing period in order to avoid billing of the next membership fee to your Payment Method. We will bill the membership fee at the then-current rate plus any applicable tax to the Payment Method you provide to us during registration (or to a different Payment Method if you change your account information). Membership fees are fully earned upon payment.

c. Holds

You may place a monthly membership on hold at any time, and the hold will take effect at the start of your next billing cycle. When the hold period has ended, your membership will resume and we will automatically bill the membership fee at the then-current rate plus any applicable tax to the Payment Method you provide to us during registration (or to a different Payment Method if you change your account information).

You may cancel a hold status at any time by clicking the words "Remove hold" on your Account management page. When you cancel a hold period, your membership will resume immediately and we will automatically bill the membership fee at the then-current rate plus any applicable tax to the Payment Method you provide to us during registration (or to a different Payment Method if you change your account information)..

d. Cancellation

You may cancel your Teeneinstein membership at any time, and cancellation will be effective immediately. You will continue to have access to the program until the current billing period ends. We do not provide refunds or credits for any partially used membership periods.
