Some people worry that Microsoft, Google, Apple or the cloud service provider would take look into their personal data.
I do not bother.
They have a few hundred million users. They don't have the time to look into the personal data of any specific user. (Only people with criminal intent will target a specific person. And they can be reported for the crime!).
Even our government is paranoid that emails could be hacked into, They refuse to send any communication by email, even though the information is quite routine, such as expiry of road tax.
I am not paranoid about "security" or "privacy". I know that there is a small risk, but it is really too small for me to bother about it.
