Exceptional Friend expiration date

Hi there, a (hopefully) quick question: When does the ‘Exceptional Friend’ subscription expire? Is it at the end of each calender month, or 30 days after purchase, or…?[li]

It’s after 30 days.

Thank you!

Likewise, if you extend your Exceptional Friendship early, you get full credit.
(IE If you have 2 days remaining, extending would make it 32 days.)

Has anybody noticed that the text for Exceptional Friend on the Nex page says “no ads?” I definitely still get ads (for Sunless Sea, for FL merch, etc), and that’s kind of annoying.
