This doesn't help. Your contact number is shared by 50 parents' phone..are you sure of their security measures.

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.
