Billing
Manage your support
The billing page is not wired up yet. Until it is, email me and I will cancel or refund anything for you by hand — that works just as well, it is only slower.
What it will do
Enter the email address you paid with, and Stripe sends you a login link. From there you can change your card, switch between monthly and yearly, or cancel. No password, and no account to remember.
In the meantime
Write to the address on the contact page. Cancellations are never questioned.
