Additional context
I am unable to locate the v5 code that submits the collected data as described in

Could you indicate where in the code the PII is sent?

Would you consider the addition of an opt-out variable that can be defined at install rather than having to email your legal department?

I should note that I appreciate the level of openness of detail as described in




but I would like to have, as a private person, better proactive rather than reactive control over this information.
