Auto-renew is an option that will renew your subscription on your behalf before your current subscription term expires, so that there is no license interruption.
In this case, you’ll be charged every term (the duration depends on your subscription) and the software will check the renewal of your license automatically if you have an internet connection. Don’t worry, if there is a problem with your payment or connection, you’ll be able to re-register your license later (or refresh it manually from the software in Help → Refresh your License in HeavyM 1.11).
If you wish to deactivate the automatic renewal, head over to your license manager and click on “View billing details”. You’ll be redirected to a platform where you’ll be able to manage your payment details and preferences.
