Cancel Your Trial or Auto-renewing Subscription
If you wish to cancel your subscription:
You may manually change this at any time in your Apple ID settings:

b. tap your Apple ID at the top

d. tap "Subscriptions"
e. select Manifest Your Soulmate (this will automatically be selected if it is your only subscription app)
f. at the bottom of the screen tap, "Cancel Subscription" to turn off an auto-renewing subscription.
This will prevent the subscription from billing you when it starts next period. Your current subscription will turn off at the end of the current subscription term.
