Cancelling: Stripe vs Apple
Where you subscribed decides where you cancel. Web subscriptions in Settings, iPhone subscriptions in Apple's Subscriptions.
Open Settings → Billing → Manage subscription. Cancel there; the plan runs to the end of the period you paid for and does not renew. Credits already added stay in your balance.
Apple bills you and only Apple can cancel. On your iPhone: Settings → your name → Subscriptions → VidRocket → Cancel Subscription, or through the App Store app under your profile. Apple's own page also works: apps.apple.com/account/subscriptions.
Settings → Billing says "Billed by Stripe" or "Billed by Apple" next to the plan.
Your account, products, creators and projects stay. You can keep using any credits you have and buy packs without a subscription.
