According to their statement: > under Swiss law, Proton can be forced to collect information on accounts belonging to users under Swiss criminal investigation. This is obviously not done by default, but only if Proton gets a legal order for a specific account. So I assume normally IP addresses aren't logged. But they can enable IP address logging for specific accounts when ordered to do so. There is very little practical difference in the protection that gives users, but seemingly the privacy policy was technically correct.
