The MoniPlus subscription is without commitment, so you can cancel it at any time and it will not be renewed.
To manage or terminate a subscription, go to the "Settings" section of your MONI customer area and click on the tab reserved for your MoniPlus subscription.
Then choose the subscription you wish to end and click on "Cancel subscription". You will benefit from the advantages of your subscription until the end of the last paid term and you will receive an email confirming the end of your rights.
