This is a WordPress template on which I added the “Newsletter” plugin (with tracking options turned off).
1 pre-installed plugin is active: the one that prevents to take over this website by trying a high number of logins, until the password is guessed.
As far as I know, this page is free from invisible tracking (no Google Analytics, no ads, no “facebook pixel”).
I suspect that only your ip address can be seen.
Let me know if you think I am incomplete.
