Put.io offers 3 days free trial on every paid plan. If you cancel within the first 3 days you will not be charged.
If you honestly forgot about canceling your plan and there is no significant usage after we have charged you, we can refund that payment. We're not here to trick you. We want happy and willing customers.
You can easily cancel the free trial from your plans page. You can go there by clicking "Your Account" and then "Change Plans"
If we accidentally charge you for any reason, we will refund that payment. Just contact us.
