You must provide Hologram with a valid credit card (Visa, MasterCard, or any other issuer accepted by Hologram) (“Payment
Provider”), or purchase order information as a condition to signing up for the Services.

Unless otherwise set forth in an applicable Order, after Your initial subscription period, and again after any subsequent subscription period, Your subscription will automatically commence on the first day following the end of such period (each a “Renewal Commencement Date”) and continue for an additional equivalent period, at Hologram’s then-current price for such subscription. Unless otherwise set forth in an applicable Order, You agree that Your Account will be subject to this
automatic renewal feature unless You cancel Your subscription at least (a) thirty (30) days prior to the Renewal Commencement Date (or in the event that You receive a notice from Hologram that Your subscription will be automatically renewed, You will have thirty days from the date of the Hologram notice). If You do not wish Your Account to renew automatically, or if You want to change or terminate Your subscription, please contact Hologram at email@example.com. If You cancel Your
subscription, You may use Your subscription until the end of Your then-current subscription term; Your subscription will not be renewed after Your then-current term expires. However, You will not be eligible for a prorated refund of any portion of the subscription fee paid for the then-current subscription period. By subscribing, You
authorize Hologram to charge Your Payment Provider now, and again at the beginning of any subsequent subscription period. Upon renewal of Your subscription, if Hologram does not receive payment from Your Payment Provider, (i) You agree to pay all amounts due on Your Account upon demand, and/or (ii) You agree that Hologram may either terminate or suspend Your subscription and continue to attempt to charge Your
Payment Provider until payment is received (upon receipt of payment, Your Account will be activated and for purposes of automatic renewal, Your new subscription commitment period will begin as of the day payment was received).
6.5 Hologram reserves the right to charge You any overage fees accrued or incurred in accordance with your Order. You acknowledge and agree that overage fees may not be invoiced in the month used and that any failure by Hologram to bill or invoice for overage and related charges on a timely basis will not be a basis for You to dispute payment of such charges.
