I didn't know there was a way to get a subscription that lasts 2 years! I see I can access that by clicking "Edit billing cycle" at https://account.proton.me/u/0/mail/dashboard
I'll definitely check that out when there aren't many remaining days for my current subscription.
Oh, I guess I didn't notice this before somehow. I don't know about other users, but it only turns me off. For a non-profit organization, they employ some of the worst marketing strategies.
