- the opening of an account;
- merchant account approval;

14. SUBSCRIPTIONS
Certain Checkout Flow services may be provided on a subscription basis.
Pricing, billing frequency and renewal terms will be disclosed before subscription.
The customer may cancel in accordance with the cancellation procedure applicable to the relevant service.
Cancellation prevents future renewals in accordance with the applicable terms but does not automatically result in a refund for services already provided or a billing period already started, subject to mandatory rights under applicable law.
15. CANCELLATION OF A SERVICE
Cancellation requests should be submitted as soon as possible to:
checkoutflowintegration@gmail.com
Where a service has not yet started, Checkout Flow will review the request according to the circumstances.

The parties agree not to improperly disclose information reasonably identified as confidential and to use such information only as necessary for the business relationship, subject to applicable legal requirements.
