May I know which OS are you using and which app store are you trying to purchase your subscription from?
The Google play store does have both fixed term and auto-renewable subscription options. The app stores give you flexibility in changing your subscription options, for example between either fixed term or auto-renewable.
You can check more information about the subscription under Subscription options in our Freedome webpage
I am able to choose, under Android devices a one month or single day but not a year option without auto-renew which is not allowed using google play-store credit.
Are tehre any plnas to allow a year subs purchase without auto-renew for Android devices?
