After upgrading Documents, you get a free 7-day trial to explore all the advanced PDF features and VPN. Your iTunes account will be charged after the trial period expires.
If you choose not to subscribe, you should cancel your free trial at least one day before the billing date. To do so:
- Open the Settings app on your iPhone or iPad.
- Tap your name at the top > Subscriptions.
- Select Documents.
- Tap Cancel Subscription. If you don’t see such an option, this means the subscription is already canceled and won't renew.
You’ll still be able to use the Documents Plus superpowers for free until the 7-day trial period expires.
