How do I change or cancel a plan?

Settings → Billing

1. 1
   Upgrade to Pro

   It shows when there is no active Pro subscription. The button says Redirecting while it opens checkout.

2. 2
   Manage subscription

   Opens the Stripe portal once a customer exists.

3. 3
   Cancel or Resume

   Cancel keeps access until the period ends. Resume undoes a scheduled cancellation. A downgrade applies at the end of the current period.
