I’m surprised anyone uses Google services considering how they infiltrate your privacy.
A Google VPN is as private to me as giving a six year old a cardboard box and asking them but to look inside.
Do you honestly believe that there is a mail service out there that does not record data on you?
Protonmail is encrypted and they literally cannot decrypt to record your data.
What is in your email isn’t the only data that sending one can generate. There’s the IP address where it was sent from and where it’s going, there’s the time of day it was sent, there’s a load of metadata attached they can read and glean information about you and your recipient. And there’s advertisement opportunities in the interface that many services use to collect info on you. There are so many ways to collect data on you through your interactions online it’s not even funny.
But yeah, keep pretending like you’ve found the only mail service that doesn’t collect any data on you at all if it helps you cope.
