If you have ARES Touch as part of the ARES Commander License/purchase, you have included a one year subscription of ARES Touch.
When your subscription is near the expiry date, you will receive a reminder. The ARES Touch Subscription is not auto-renewed: You will not be charged automatically and are free to decide to renew or not.
If you don’t renew your subscription, you will lose access to the premium features of ARES Touch’s Full mode. You will be able to use the features of the Simple and View-only mode for free. To recover access to the Full mode features, you can always buy an ARES upgrade to get another one year of ARES Touch.
If you purchased ARES Touch individually (via Apple AppStore or GooglePlay), the same principle applies, and in order to recover access to the premium features of ARES Touch’s Full mode, you will need to renew your subscription.
