30 days before your subscription expires, teamviewer send you a friendly email to remind you to that your subscription expires in 30 days and to be sure to renew before then in order to not lose service.
What that email does not tell you is that unless you cancel your subscription at least 30 days (ie on that very day) before your sub expires they will renew you automatically and demand a full year's subscription under threat of legal proceedings.
Personally I believe that the purpose of this email is to lull you into a false sense of security that you can just let your subscription lapse instead of renewing when that is far from the case.
