Source in Swiss law? 'By default' is of course legalese. If a user can turn on the IP logging feature, you can too. And you did in at least one case according to your own transparency report: 'In April 2019, at the request of the Swiss judiciary in a case of clear criminal conduct, we enabled IP logging against a specific user account which is engaged in illegal activities which contravene Swiss law. Pursuant to Swiss law, the user in question will also be notified and afforded the opportunity to defend against this in court before the data can be used in criminal proceedings.' https://protonmail.com/blog/transparency-report/ https://protonmail.com/blog/transparency-report/
