Installing HASS app on child's phone for info reporting but prohibit access?

I’d like to install the HASS companion app on my son’s Android phone so that I can pull information from his phone into HASS itself, however I do not want him to have access to dashboards or anything really. I haven’t found a way to do this in the app, as there isn’t really a permissions system. Can someone recommend the best way to do this?

Have you tried using the “Allow person to login” switch when you setup the person? I haven’t but all indications are that if you turn it off they can’t login.
