I'm working on an R shiny app for my employer with lots of data analysis information, however, we need a way to host the app so we can share it with the public. We're looking at Shinyapps.io to host the app but are concerned about security. Our data contains sensitive information that cannot be shared publicly(names, addresses, etc.). We would also need to update the data, probably daily, to keep it up to date. We use 2 excel files/sheets, one is around 115,000 x 23 cells, the other is 1,250 x 30 cells.
Is Shinyapps.io good for this?
