The Dyrt PRO subscription comes in several forms.

Yearly with 7 day trial:
This creates a subscription that starts with 7 days free and then converts to a paid yearly membership with the card on file starting on day 7. (We will use the card you have on file with Apple for app purchases, the card on file with Google for the Play Store purchases or the card you entered during checkout on our website.) 

Yearly purchase:
Some people just know PRO is what they want and opt for a straight purchase. This version does not have a trial, but will charge the card on file immediately (the card you have on file with Apple for app purchases, the card on file with Google for the Play Store purchases or the card you entered during checkout on our website.)

Monthly:
This monthly option is only available through Apple or Google and does not come with a trial. It's a straight purchase, but it's only charged one month at a time so you only have to pay for the time you use. You can cancel any time and only pay for the single month you paid for. There are no refunds for monthly purchases.
