r shiny - is uploaded data safe and secure?
<p>I'm building a shiny app where users upload transaction data to get access to an analytics dashboard.  Can I assure these people that their data is secure from sniffers/hackers and will be removed from the shiny server when their session expires?  How does this actually work in Shiny?  (Note that I'll be hosting my app on shinyapps.io)</p>
