I want to prevent Google Analytics from recording the activity that I have on my own website to avoid contaminating the data it collects, for this I would like to put a filter that excludes the IP address of my router so that all my devices are excluded even though I know it is not the best option because it would not register the data of others who share my same IP on the internet, but the system that uses cookies is not feasible in my case. Other options that do not include cookies are welcome.
I have noticed that there is a filter that Google Analytics gives us by default with this objective but I don't know how to configure it, it is the one shown in the following image:
It seems unintuitive to me, after testing and reading the documentation I have not been able to find a way to make it work. It keeps recording the activity of my devices.
