Subscriptions shall be automatically billed for each subscription period and automatically renewed unless canceled. Add-ons may have billing periods and billing cycles that differ from those of the Base Plan. The free subscription plan is automatically canceled after one year.

For more information on canceling a subscription, please refer to the FAQs. If a subscription is canceled, the Registered User will continue to have access to the Data or Add-on until the end of the remaining billing period applicable to such Subscription, after which access will no longer be available.

The Registered User will be notified by JPXI of any increase in prices for a subscription plan (including both Base Plans and Add-ons). The price increase will be applied to the next payment after the notice, provided that the Registered User has received said notice at least 30 days prior to the payment date. If the period between the advance notice and the payment date is less than 30 days, the increase will be applied to the subsequent payment after that date. A Registered User who does not wish to pay the increased price for a subscription plan may cancel its subscription. If the Registered User notifies JPXI of cancellation by the end of the current billing period, the user will not be charged for any further subscription plan.

For more information on changing a Base Plan, please refer to the FAQs. If a Base Plan is changed during a billing period, the fee for said period will be calculated on a daily pro rata basis according to the Base Plan before and after the change.

Add-ons are subject to additional terms and conditions separately specified by JPXI.
