From what I understand Google reads/scans all my emails so that they cab "provide" targeted ads and maybe for other reasons.
If a have a group of people who want to hide their emails from Google, how can they best do that in a simple way? Maybe the group has a topic that they are discussing that they don't want Google to know that they are discussing.
The only idea I have is to use a simple encryption. My question is if the simple ROT13 will substitution will work? I understand that few people probably have a good insight into how Google's email scanners work, but maybe someone can make a qualified guess?
Again, I am not interested (in this question) in strong encryption, just something that can hide text from the email scanners.
EDIT: Just to make it totally clear, I am only interested in how to hide things from the automated scripts that Google uses to scan my email. I am not interested here in the situation where a Google employee manually looks at my email.
