You can use all major credit cards.
There's no contract on any plan. You just pay as you go, and you can cancel any time without penalty.
Don't worry, your work will not be lost and you can continue with the Bkper Free plan for as long as you want, until you get ready to upgrade.
We will credit your account on a pro rata basis for the remainder of the period, to be used in a new plan, or in the future, if you reactivate your subscription.
