I’m aware of the first aspect, but since my concern was more not to irritate the average user than to actually protect the already anonymised data, the solution can be considered.
I’ll have to investigate that carefully, thanks for the hint.
I had expected there would be an option to set up some sort of access restrictions for the public/anonymous user (similar to setting up a preconfigured dashboard for users), if that is not possible then that might be something worth considering some time.
Arguably, a public live visitor map is a somewhat kinky thing to have, but lots of smaller community sites feature something similar (https://www.revolvermaps.com/ is a service offering such maps that springs to mind, which I would not recommend for data privacy concerns).
Anyways, thanks again for your response!
