To remove any doubt, we confirm that Proton Mail has not and does not engage in voluntary real-time surveillance on behalf of law enforcement. We also confirm that Proton Mail cannot be used for any purposes that are illegal under Swiss law. Not only is this against our terms and conditions, we are also obligated by law to assist police investigations in criminal cases. Additional details can be found in our transparency report:
