Managing your subscription

You can manage your subscription from Settings at any time. Billing runs through Stripe, so the change itself and its timing are confirmed there.

How to change your plan

Go to Settings, open the Billing tab and choose Manage billing. That takes you to the Stripe billing portal, where you can change or cancel your plan and update your card, and Stripe returns you to Blueprint when you are done.

Cancellation

Which answer applies depends on your plan. Monthly can be cancelled anytime, and you keep Pro through the end of the month you paid for, then move to the free tier with your data intact. The application cycle is paid once rather than subscribed to, so there is nothing to cancel and nothing that renews; your access runs to the end of the cycle you bought and then moves to the free tier the same way.
