Info about renewal

I have had it with the onslaught of emails from ccleaner LONG before I have to renew. They suggest renewal is imminent, but they were hounding me weeks ahead of time... what an annoyance. Then they re-upped me in October but according to my records it's in November and sure enough this will last until November of 23. However I don't appreciate this and will also not appreciate it next September. I want to un-enroll from automatic renewal and CCleaner is making that very difficult as well. Please advise.
