How do I upgrade from a free trial to a paid subscription?

At any point during or after your free trial you can upgrade to a paid subscription by logging in to your Harpoon account and visiting your Subscription page. Here you’ll be able to select a subscription plan, fill out a credit/debit card form, and upgrade to a paid subscription. From that point on your credit/debit card will be billed monthly or yearly (based on the plan you selected) and you can cancel at any time using the same Subscription screen.
