This is an accepted solution.
Please go to edit code and locate footer.liquid under sections folder and then look for below pattern of code and if you find it...just put the information in the place where i have added text "Please add your info here"
<div class="grid medium-up--grid--table">
<div class="grid__item medium-up--one-half"> Please add your info here</div>
<div class="grid__item medium-up--one-half medium-up--text-right"><span class="visually-hidden">Formas de pagamento</span>
<ul class="list--inline payment-icons"><li>
and before you attempt this please do not forget to duplicate the theme to avoid issues due to accidental changes
