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 IP addresses are not logged by default, and you can see when they are in our Privacy Policy: https://proton.me/legal/privacy

Nothing has been reengineered - this is how it's always worked, and we have been transparent about it since we started in 2014: https://proton.me/blog/protonmail-threat-model

You may be referring to Proton VPN, which is a completely no-logs service: https://protonvpn.com/blog/transparency-report

@protonprivacy from that link:

2.5 IP logging: By default, we do not keep permanent IP logs in relation with your Account. However, IP logs may be kept temporarily to combat abuse and fraud, and your IP address may be retained permanently if you are engaged in activities that breach our terms and conditions (e.g. spamming, DDoS attacks against our infrastructure, brute force attacks). The legal basis of this processing is our legitimate interest to protect our service against nefarious activities. If you enable authentication logging for your Account or voluntarily participate in Proton's advanced security program, the record of your login IP addresses is kept for as long as the feature is enabled. This feature is off by default, and all the records are deleted upon deactivation of the feature. The legal basis of this processing is consent, and you are free to opt in or opt out of that processing at any time in the security panel of your Account. The authentication logs feature records login attempts to your Account and does not track product-specific activity, such as VPN activity.

it sounds like you or the swiss government can arbitrarily decide to start logging IP addresses without being compelled to notify users? is there a reason you don't make a commitment to notify users whenever their IP address is logged? does swiss law put you under a gag order, or are you just not interested in notifying users when their privacy may be compromised?

@hipsterelectron It's never arbitrary, there's legislation that limits this. Also, gag orders are not legal in Switzerland.
@protonprivacy you did not link to the legislation that limits this, and you did not respond to my point about notifications. if there is no gag order, then why not notify users whenever their IP address is being logged?
