No, unless you approve of the payment, you will never be automatically charged. Don't worry!😉 RedKiwi only offers purchase of RedKiwi Premium, not the subscription of RedKiwi Premium.

(For your information, there are two types of payment in in-app purchase. One is subscription or Recurring payments, which is automatically paid every certain time(usually every month). Another is purchase, which is just a one time payment.
