Will my subscription automatically renew after a month?

No. Unlike other subscription services, My Cognitech Cloud does not automatically charge your card to extend the subscription. You can renew your software access at anytime after your subscription expires. Once your prior subscription has expired, you can change the length of your next subscription.

Please view the following article to see how to renew after your 1 month subscription expires:
