Hi, I would just like to add to this, I have been under a police investigation for some time, and although they are wasting their time. I do take every precaution to preserve my privacy. Which just seems to make them more angry. I have a proton main account, and and cant be specific. But I can say with a degree of certainty that not only can the police gain access to the contents of your proton main account with little effort, they also have the ability to remove login instances from history. As I saw a IP login from a certain location, when I got back from work that instance of the successful login was missing. I know what that morning I entered the IP into a IP lookup website, I even saw what area it come from. I hope this helps people make a informed decision about using proton mail. Because if the police have got it in for you, they will just lie and make up reasons and make the Swiss police feel bad for not acting or helping.
