Basic back-end question

[brinkworthc]

Hello,

Are Zoom SMS messages stored in the cloud or locally (on mobile / desktop) devices?  Are Zoom SMS messages accessible centrally (via admin credentials) or do you need account credentials for each user? As a bonus question, if any SMS messages are deleted, are there any options for recovery of those messages?   I appreciate any feedback and/or links to resources that help with the answers.

(I suspect I know these answers but am verifying)

Thank you.
