Install GrapheneOS on a Pixel. Most Android apps just work, and unlike the stock OS, it does not spy on you.
Even if I keep everything safe many govts are using Microsoft cloudfor day2day operations. Recently my employer lost tons of data. Every CV you send to a company or recruitment is kept often unencrypted. Every other country is fingerprinting/face ID upon arrival. Are you sure about their security?
Things that I have dumped into my email are far less consequential compared to those.
The game is lost. Very few people can have privacy.
