Protonmail is cop friendly. Any reasonable privacy aware email provider would hash the secondary email, not store it as cleartext. I implemented secondary email hashing for Riseup to prevent exactly this thing, over a decade ago.

Proton Mail Discloses User Data Leading to Arrest in Spain

Proton Mail came under scrutiny for its role in a legal request by the Spanish authorities leading to the identification and arrest of a user.

Also, WTF logging IP addresses?! I don't know about Swiss law, but at least in the US if you design your system so that you can't gather certain data you can't be compelled to re-engineer it to gather that data just because the cops want it. That is what the whole FBI versus Apple case was about, and the FBI backed down rather than lose in court
@elijah a few years ago i was talking with an an anarchist in their teens who said "I went with Riseup for email instead of Proton because Riseup was designed by people who understand activism and Proton was designed by scientists." Hard to argue with that!
@jdp23 @elijah i wish i was able to get riseup, sadly they aren't allowing registrations currently and im unable to find an invite code, there arent any good email providers anymore.

@vendetta02 @jdp23 @elijah

Here's a list of nice tech collective that host different services for people, including emails. A good part of them don't require invite.
