I hate apps, They are all spyware for the most part. I do have a couple on my PC. One allows my encrypted Email service to interface with Outlook. Another is Poler Starts. Once my security software caught it trying to access my browser history. I wrote them an email about it and they gave me a flimsy excuse since I had to DL their app and do not play using a browser.
I have CCleaner, I have PDF-XChange Editor, UltraSearch instead of the Microsoft search, AOMEI Backupper to auto-back up the PC to an external drive weekly, 2 years of Turbo Tax as I have used it since it was a DOS based program and a small app that blocks anything Google Chrome related. Of course I a few browser extensions for both Fire Fox and Pale Moon browsers which I use.
I do everything in my browsers. I have software which deletes everything I do online when I close a browser window. I do not use Tabs but every site is opened in its own browser window. I store no history or passwords on the PC.
Like I said, I am a privacy nut. I try really hard to keep "Big Brother" from watching me. I have never visited an App Store either. If you Google my screen name you get back a ton of hits. If you Google my real name you get nothing back. However, If you ask Google search the one right question, it identifies me by my real name and my screen name. You cannot find a picture of me online. At least, I cannot do so.
Every few months I Google my real name to see what might be out there and nothing useful comes up except some links to places which claim to give you my info if you pay. Most of them give minimal info without payment and all of them have me living in places I have not been in over the last 78 years for more than a total of a few days. They also let you know the names of my dead parents.
I used to be in a Wall Street Softball league and we played games in Staten Island and Brooklyn in the 1980s. I also war games a couple of times in Brooklyn also in the 80s. I have never lived in either of those two NYC Boroughs Here is a list of states where I have lived that they missed: NYC, Washington DC, VA and CT.
