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.

@elijah I really dont get how you use email recovery with an hashed email address. Anw, u should not put a recovery email if u want privacy. Second, keeping IP address might be in swiss law, in France u have to but eu law says it personnal data and it shouldnt be stored without consent.
