I have seen this: Shiny - Shiny App Usage Tracking but it is quite old.
I am worried about the legallity of using google analytics without the user's consent (google analytics is dealing with IP adresses, that is personal data following GDPR rules). See How do I use Matomo Analytics without consent or cookie banner? FAQ - Analytics Platform - Matomo for an explanation of my concerns.
I think it would be nice to update the help page with some additional information about the need of a consent screen if using googleanalytics.
I was also wondering if there was a simpler solution than matomo around nowadays ?
