>In its transparency report, ProtonMail explicitly mentions the possibility of real-time surveillance („ProtonMail may also be obligated to monitor the IP addresses which are being used to access the ProtonMail accounts which are engaged in criminal activities“). ProtonMail even mentions a current case of real-time surveillance:

>"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."
