If you do not cancel your trial subscription before the trial expires, it will automatically roll over onto a paid plan, and you'll be charged immediately. Please note that all plans are auto-renewing, which means the plan will continue to renew and you will be charged at each renewal, as long as the plan is active.
If you do not wish to continue with a paid plan after your trial, you can downgrade your app to our Free plan anytime before the end of the trial to avoid rolling over onto a paid plan.
