It's preemptive for when you DIE. That's why in the screenshot you sent it says "in the event of my death", not "if the government comes knocking, violate the law and delete my data first".

You can delete your data from Proton, too, but the payment information, which was how this person was identified, is stored regardless by their third-party payment provider.

Mailbox only erases your payment info 4 weeks after you've last paid, and ended your contract with them, and they use Ayden for payments, which also has no set date at which they'll delete your payment information.

You're not understanding. They can order whenever.
