If you subscribed in the iOS app, cancel through Apple: open Settings on your iPhone, tap your name, then Subscriptions, then AutoInvent. We can't cancel an App Store subscription on your behalf, and deleting your AutoInvent account doesn't stop Apple billing you — cancel with Apple first.
If you subscribed on our website, cancel in your account settings at autoinvent.com.
Either way, you keep access until the end of the period you've already paid for.
