When you sign up for an account on the COZYROC Cloud, you can choose a monthly or an annual subscription (you get 20% off with an annual subscription). Your 14-day trial starts upon confirming your e-mail address. While your trial is active, you can use all of the features of the application. When you are ready to become a paid customer, go to the Subscription page and enter your payment details. After your trial expires, your data will still be accessible, but you won't be able to execute packages (neither scheduled, nor on-demand).
NOTE: The billing and payment collection is handled by Stripe and Zoho Subcriptions. From your Subscription page, you will have access to a Zoho Subcriptions customer portal, from where you can view and download information about your invoices and payments.
