To cancel your OnForm subscription, simply follow the instructions here:
Open the Settings app on your device.
Tap your name.
Select "OnFrom" from the list. If you don't see OnForm on the list, you don't have a subscription through Apple.
Tap "Cancel Subscription". If you don't see this button, the subscription is already canceled and won't renew.
(Optional) Please email us at email@example.com and let us know why you are canceling. Your candid feedback will be incredibly helpful in helping us improve OnForm.
