Using Keap following a no-deal Brexit

Hi All, Is anybody else concerned about the effect of a no-deal Brexit on transfer of data that may be stored in the US. I suppose one question I need answering is where are the servers located where the data I load into InfusionSoft are stored? I have seen that something called the EU-US Privacy Shield Certification is no longer operational, so I am not sure where to start in terms of establishing that it will be legal to continue to send data to be stored by InfusionSoft after 31 December, if there is no deal. Many thanks for any pointers. See also here: https://www.gov.uk/guidance/using-personal-data-in-your-business-or-other-organisation-after-the-transition-period
