>The firm's privacy policy, which was updated yesterday, now says: "If you are breaking Swiss law, ProtonMail can be legally compelled to log your IP address as part of a Swiss criminal investigation."
That makes it sound like they normally do not / did not log the IP, but then got orders from the police the log these particular IPs.
I was even considering switching to them...
As far as I understand according to several comments I read here in HN "99%" of the people don't understand what "by default" means, making the sentence misleading for most.
Throwing in a word like default changes the entire meaning.
Instead of we don't log anything*
* we log only when requested
They should say your ip can be logged.
It's like saying in big headline.
No meat burgers *
* meat means carots
