Subscriptions on Google Play and the App Store renew automatically unless you unsubscribe, but you can cancel your subscription to MileOn Premium at any time if you decide you no longer want it.

To cancel, simply follow the instructions provided by Google and Apple on how to cancel subscriptions through their app stores. 

After your subscription has been cancelled, you’ll still be able to use MileOn Premium for the remainder of the month for which you've already paid, and then MileOn Basic will remain available for use through the app at no charge.

IMPORTANT:  Simply uninstalling the app will not cancel your subscription.
