Quite a lot. It is very, very hard to find info about me on internet, as I don't have any other profiles elsewhere except the forum here. And here too, I had not provided any personal info about me to general public, and whatever that is written there is about my ideas and thinking. I don't have any social media account as such, so finding info on me is not possible via that way as well.
I also use variety of extensions on the browser to avoid any sort of cross-site trackers sneaking up on me, plus I had customised Firefox browser to hardened privacy settings. As I had said earlier few times that I live quite solitary life, hence even for real-life person it is tough to find me.
I don't give my original mobile number or email IDs to malls, shopping plaza, restaurants, online services, etc. excluding genuine necessary services. And hence I always make sure before checking out from those listed places so that they don't even bother to call me back. I never use WiFi services provided by various places like hotels, airports, railways, etc.
Very few people know about me, and that will be like that until I trust some another person to disclose a bit of info !!
