Edit inline and pop-up form footer verbiage

I would like to change the statement into "[ ] I agree to receive marketing and customer service calls and text messages from [Company]. Consent is not a condition of purchase. Msg/data rates may apply. Msg frequency varies. To opt-out, you can reply 'stop' at any time or click the unsubscribe link in the emails. [Link to Privacy Policy]". and would it be possible to add a checkbox? Thanks!
