Man... there has to be a "security" wiki - a living document, that instructs you on how to be as anonymous as possible and how to setup all the required tools to stay anonymous.
Somewhat O/T:
Recently I discovered that Amazon store app spies on your Google searches. If I search for a solution, say a pool heater and Google lists websites, including stores with pool heater products, as soon as I open my Amazon store app and type p - o, it lists pool heater at the top. This also happened when I was searching for a pool ionizer, literally I Googled, "keep pool clean without chemicals", without clicking any of the links provided on Google, I saw a product listed, "ClearBlue Ionizer", open the Amazon store app, I wanted to find just general ionizers so I didn't start with the name of the brand, instead I wanted to search for ionizer, by the time I finished typing "ion"... it listed "Pool Ionizer by ClearBlue Ionizer (25,000 Gallon) ... "
At that moment I realized Amazon is tracking my searches. I get they want to be convenient but I don't remember Amazon giving me the option to opt out of information sharing amongst other apps.
Hopefully sooner or later there will be a way to sandbox every app so they're not communicating with each other.
