No. Like the edits suggested by WordRake, the decision to renew WordRake is up to you. We will suggest renewing it when your current subscription is about to expire, but there is no automatic renewal. The renewal process is the same as purchasing your first license; you will receive a new license key to input into WordRake.
If you decide not to renew, WordRake will remain in Word or Outlook, but will feature greyed-out operation buttons. Once the existing license has expired, the buttons will remain greyed-out until a new license key has been input.
