Signal and Proton Mail – What Private Information Can Law Enforcement Access?
On a regular basis I see questions being asked about the privacy of Signal and Proton Mail in terms of potential law enforcement access. It seems reasonable to me to be skeptical – we live with a large number of Internet vendor applications and services that do not respect our privacy and which capture information about us to sell to data brokers or advertisers. Some of companies pro-actively work with law enforcement and government agencies, and all of them will surrender our information when legally required to.
Here are some basic factors that affect our risk when using applications:
• Does the application vendor profit from selling our private information?
• Does the application vendor minimize the information that they collect and retain?
• Under what legal jurisdiction do these vendors operate?
Signal and Proton both have a reputation for privacy in their respective messaging and email applications. I thought it would be good to try to provide a summary of their privacy positions and what information they can actually provide to law enforcement. Based on publicly available information, here is a summary of the information that can be acquired from Signal and Proton by law enforcement:

Please note: Nothing in this summary recommends or suggests using Signal or Proton Mail for illegal purposes.
Signal retains extremely little personal information and does not monetize any information about individuals. Due to the nature of the email protocol, Proton collects a bit more information but does a good job of protecting the content of email messages you send to other Proton users. Proton does not monetize your private information and operates under Swiss law with high levels of privacy protection.
There is no such thing as perfect privacy on the Internet, but Signal and Proton both provide vastly better protection for your privacy.
