Maintain two systems, and never ever mix their content. One simple one with non-Windows and only meant for banking or trusted shopping, very sensible emailing with adresses you never share with just anybody, the other system for surfing, gaming, working, whatever.

I do so since years.

And never ever have email adresses, emailing, shopping, paying, banking installed on your cellphone. NEVER. Nothing personal on your smartphone. NOTHING expect your google account data.

Needless to say: keep your google account empty and tidy, do not use their services requesting you to have GPS and tracking on, personal profiling on, personal data sharing on, cloud computing on, all that beeping, blinkling sweet candy-kind of glamour child's play-stuff.

Think of all that as refined white sugar or glucose sirup. Its sweet, it makes many things taste better, its offered everywhere, all the time, in everything, the temptation is omnipresent. But your health is better off without it. Even more, your health will NEVER EVER benefit from it in any way if you consume it.
