Trials in the App Store work by delaying the start of your subscription for a set period of time. When you activate a trial, you will be asked to confirm your choice and that you are aware of its terms. We will always declare the length of the trial, and the full price of the subscription that comes into effect once the trial ends.
If you want to cancel a free trial without a charge, you need to cancel before 24 hours prior to the end of the trial.
If the trial is not cancelled, Apple will upgrade you to the regular subscription and then renew it automatically.
Trials and introductory offers are only available once. Once you have used a trial, you cannot extend or reset it. We will always provide the full information on whether a trial is available to you. If you sign up for a subscription after using a free trial (no matter when it was activated), the App Store will charge you the subscription price immediately.
